It has been in the news for quite a few years that Australia is planning on shuttering the 3G network, and it is finally happening in phases. Vodafone was the first to do it, by closing down its 3G operations between December 2023 and January 2024. Telstra and Optus will follow suit in 2024, in the month of June and September, respectively.

How does the 3G sunset affect Australians?

The 3G sunset has brought on a wave of panic that nearly three quarters of a million Australians might be cut off from emergency services with the handsets they presently use. It means they won’t be able to dial the emergency Triple Zero number (Australia’s main emergency service) when Telstra and Optus close their 3G networks. To combat that issue, The Australian Federal Government has created a Working Group to ensure the transition from 3G to 4G is seamless as possible.

The new group was established a couple of days after Australian Communications Minister Michelle Rowland spoke about the problem, and asked the three major mobile operators – Telstra, Optus and TPG ( formerly Vodafone Hutchison Australia), along with the Australian Mobile Telecommunications Association (AMTA), to join the working group. It is being supervised by the Department of Infrastructure, Transport, Regional Development, Communications and the Arts.

What will be the focus of the Working Group?

The announcement of the 3G network switchover was first made in 2019, in order to provide a more efficient use of spectrum by mobile network operators, to improve data speeds and capacity.

A common problem detected is that many customers are using old 4G handsets, and believe their device will automatically function using 4G, once the 3G network is permanently shuttered. The handsets could continue to operate normally for voice and data, which is why many are unaware of the impending concern.

The Working Group will target a subset of 4G handsets configured by the manufacturer to use 3G for calling Triple Zero, despite otherwise working over 4G to make voice calls. It is indeed very troubling because users won’t know that their handset can’t call Triple Zero after the switchover. It can only be discovered during an emergency when they try to dial.

What efforts are being undertaken?

The Working Group is collaborating with industry experts and stakeholders to identify impacted customers, improve accessibility of public-facing information and contact points, and amplify messages to ensure the community is aware of the switchover.

Telcos are reaching out individually to advise customers with older 4G phones, devices purchased overseas and now being used in Australia, or those bought via the “grey market”,

about their handsets not being properly configured to make emergency calls post the 3G shutdown. The three mobile operators have been asked to submit action plans at the earliest, and instructed to update on a fortnightly basis.

Older 4G handsets don’t support VoLTE emergency calls. They have VoLTE capability that enables voice calls and Internet access, but these devices revert to 3G for emergency calls. Australians have been continuously urged to upgrade affected devices or get new ones to ensure they have connection to faster 4G and 5G mobile services.

If warranted in the public interest, options exist under law for the Government to consider regulatory intervention – including proposals for delays to planned switchovers, subject to required consultation and procedural processes. However, consumers have been strongly discouraged to avoid placing test calls to Triple Zero. This is because impacted gadgets will still work over current 3G services until the 3G switchovers occur later in 2024. Moreover, it could disrupt the networks and prevent others from accessing live-saving support.

What triggered the threat?

Telstra’s power outage

The inability to contact emergency services was highlighted when a person from Melbourne, Victoria, died due to cardiac arrest during a Triple Zero outage that affected the Telstra network. Telstra is the national emergency call provider which directs calls to emergency service organizations around the country.

The deceased’s family tried to call for help, but the call couldn’t be forwarded right away to paramedics. The outage lasted for more than an hour, during which Telstra operators could answer calls but failed to redirect them to all Triple Zero call centers. The outage lasted for 90 minutes, and among the almost 500 calls to Triple Zero during that window, Telstra was unable to transfer 148.

The service was intermittently malfunctioning between 3.30am and 5am, which meant that some operators had to resort to email referrals. Triple Zero Victoria operators couldn’t receive those until well after 7 am. By the time the paramedic crew responded to the Melbourne patient experiencing cardiac arrest, it was too late, and the resuscitation efforts were unsuccessful.

Optus’ breach of public safety rules

Optus had to pay a hefty fine of $1.5 million Australian dollars (US$980,316), when it was found guilty of large-scale breaches of public safety rules around its Triple Zero system, putting many consumers at risk.

The ACMA conducted a thorough investigation, and discovered that the operator hadn’t uploaded required information of almost 200,000 mobile customers to the Integrated Public Number Database (IPND) between January 2021 and September 2023. The INPD is utilized by services like the Emergency Alert service to warn Australians of disasters such as floods and bushfires, and by Triple Zero to provide location details to law enforcement, ambulance and fire brigade in an emergency.

What does the current scenario look like?

The AMTA flagged this issue in November, 2023 – three weeks before Vodafone started phasing out its 3G network from December 15. AMTA CEO Louise Hyland had previously stated that customers have to act immediately if they have an older mobile device that still connects to a 3G network, which hasn’t been upgraded. It has listed 20+ common devices that are likely to be affected by the 3G closure.

The government is closely monitoring the transition. As mentioned, there are various options in law, which include potential proposals to delay the 3G switchovers. Telstra is next in line to shut down its 3G networks, and working closely with other mobile network operators, the ACMA (Australian Communications and Media Authority) and the federal government to manage Australia’s transition from 3G to 4G. The switchover is crucial for the connectivity and future productivity of the country, to be achieved via increased speed, efficiency, and capacity. As per their spokesperson, 3G now accounts for only 1% of Telstra’s mobile network traffic. Many of their customers had begun upgrading their mobile devices ever since the 3G shutdown was announced 5 years ago.

With 740,000 customers about to be impacted by the 3G shutdown, will the government step in to delay the switchover? Communications Minister Michelle Rowland has assured Australians of a safe transition. As per the latest update an inquiry has been initiated due to the Senate voting in favor of a One Nation motion into the 3G mobile network shutdown. One Nation Senator Malcolm Roberts stated that telcos have to delay the 3G sunset till the inquiry is complete and it is 100% certain that Australians are ready for the switch.

The 3G network shutdown has already begun in Australia, with Vodafone kicking it off on December 15, 2023. Rival telco Telstra will switch off its 3G network on June 30, 2024, while Optus has set a date for the switch-off as September 2024.

How does the 3G shutdown impact security of businesses?

The 3G sunset has a considerable impact which includes business disruptions, regulatory compliance, increased vulnerabilities, data privacy concerns, and hacker exploitation. Threats arising due to outdated protocols could expose sensitive data and compromise the integrity of operations. Take a look:

• The 3G shutdown can expose systems to cyber threats as many businesses still use 3G networks. As they are phased out, security patches and updates for these systems may stop, giving hackers an excellent opportunity to attack.
• The process of transitioning from 3G to newer networks introduces vulnerabilities that cybercriminals may exploit. During this period, devices are generally more susceptible to attacks as they adapt to new network configurations.
• Older devices might not be compatible with 4G/LTE, so transitioning would be problematic.
• The encryption protocols used in 3G networks might not be as robust as those in newer networks. Inadequate encryption can lead to unauthorized access and interception of sensitive data.
• Phishing and social engineering have become common these days – cybercriminals con people by posing as representatives of network providers, giving phony upgrade alternatives or providing false information. Users could be tricked into installing malware or giving out personal details via social engineering attacks.

Why upgrade to 4G/LTE?

People are still asking – is 3G still available in Australia? It is, in limited capacity, but the 3G shutdown (Australia) for major telcos is imminent in 2024, so it is advisable to make the switch immediately. The 4G/LTE network offers a range of benefits that significantly enhance your security system’s performance and reliability:

Faster Communication

4G technology provides quicker data transfer, ensuring that your information is transmitted within seconds.

End-to-End Encryption

All data transmitted over the network is encrypted, providing a secure communication channel.

Improved Authentication

Advanced authentication mechanisms are implemented to safeguard against unauthorized access. 

Future-Proof Security

As 3G networks are gradually being phased out, upgrading to 4G ensures that your device remains up-to-date and compatible with the latest advancements.

How to secure 4G networks?

Rather than researching the exact date of when will 3G be turned off in Australia, it is time to start preparing for the future:

Understand the risks 

The first step to securing your 4G networks is to understand the risks and potential impact of a security breach. You should conduct a thorough risk assessment to identify the most critical assets, likely threats, and effective countermeasures. You should also monitor the network performance, traffic, and anomalies to detect any signs of malicious activity.

Encrypt the data

Encryption ensures that even if data is somehow accessed by unauthorized parties, it remains unreadable, while authentication verifies the identity and integrity of the devices and users. Strong encryption algorithms and keys are used to implement mutual authentication between the network elements and the devices.

Implement firewalls and VPNs 

Implementing firewalls and VPNs (Virtual Private Network) are a must, in order to control the access the traffic of your 4G networks. Firewalls filter the incoming and outgoing traffic based on predefined rules and policies, and block any unauthorized or suspicious connections. VPNs create a secure channel between devices and the network, while encrypting data in transmit. You have to configure the firewalls and the VPNs according to the network requirements and the security standards.

Updating and patching software

There will inevitably be bugs and vulnerabilities that hackers can exploit to compromise the network. You should regularly check for the latest updates and patches from the vendors and providers, and install them as soon as possible – they can easily fix these issues.

Training consumers

Users are generally the weakest link in the security chain, as they could fall victim to phishing, malware, or cyber attacks. Provide users with clear and simple guidelines on how to use the network safely and securely, and the process of reporting any incidents or issues.

Review and audit security measures 

It is very important to review and audit the security of 4G networks consistently. Evaluate the effectiveness and efficiency of security measures and policies, while identifying r weaknesses. Conduct regular audits and tests to verify the compliance and the performance of the network security, and make any necessary adjustments or improvements.

Security Features of 4G/LTE Upgrades

Authentication and Encryption

4G networks make use of mutual authentication between the user device and network. The device always verifies the network’s identity and vice-versa, via keys and certificates. Data transmitted over air interface is encrypted using strong encryption algorithms like Advanced Encryption Standard (AES). This encryption ensures that even if data is intercepted, it remains unreadable without the decryption keys. There is another type of authentication where Subscriber Identity Module (SIM) or Universal Subscriber Identity Module (USIM) cards are used. They store cryptographic keys and play an integral role in ensuring no one gets access to the network except authorized users. 

Key Management

Robust key management protocols are used to securely handle encryption keys, ensuring their confidentiality and preventing unauthorized access to these critical keys.

Segmentation

Virtualization technologies separate different network services, preventing security breaches from spreading across the entire network if one segment is compromised.

Protecting Integrity

Using Hash-based Message Authentication Code (HMAC), integrity protection is established, to ensure that the data being transmitted is authentic and hasn’t been tampered with. Device integrity lets only authorized and verified software components get loaded during the boot-up process, so no malicious code can be executed. Internet Protocol Security is also implemented for secure communication between network elements, thus providing a secure channel for data transmission within the LTE network. 

Improved Privacy Protocols

It is necessary to protect location privacy of users; temporary identifiers are often used instead of static identifiers – these make it tougher to track a user’s movements. For subscriber identity privacy, temporary mobile subscriber identity (TMSI) and pseudonymization are used to hide the actual identity, thus reducing the risks associated with tracking. 

Firewalls 

Mobile networks implement firewalls and Intrusion Detection Systems for round-the-clock monitoring. They are used to control the traffic entering and exiting the network – you can detect and prevent unauthorized access attempts, malware, and other breaches. There are Access Control Lists too, which are created to specify which devices or users are allowed to access network resources, thus preventing unauthorized access.

Lawful Interception

Rest assured, 4G/LTE networks have protocols in place to support lawful interception. So if there is a chance of data breaches, authorities can monitor communications in compliance with legal requirements. If any threat is detected, they can intervene and take prompt action. When does 3G end in Australia? That is what everyone wants to know! But businesses and consumers have to start preparing beforehand. The former should begin talking to cybersecurity organizations and seek certifications for the upgraded network’s security measures. As of now, the 4G/LTE upgrades will be rolled out in phases for minimal disruptions, but dedicated customer support channels are being established to ensure a smooth transition. Businesses have to train network operators and support staff on the new security protocols and features, without further delay!

The world of telecommunications is certainly evolving at a swift pace, and with technological advancements, older networks are becoming obsolete. The 3G shutdown (Australia) is being much talked about these days, ever since it was announced by the Big Three - Vodafone, Optus, and Telstra.

What will 3G be turned off in Australia?

The Australian Communications and Media Authority (ACMA) have set deadlines for the 3G network shutdown. Here is a timeline to give you a better idea:

• The announcement about the 3G shutdown (Australia) was made several years in advance to give individuals and businesses ample time to switch to newer networks.
• Providers had opted for a phased shutdown to minimize disruptions. It involved decommissioning 3G cell towers and reallocating resources to support 4G and 5G networks.
• Telecommunication companies have been actively communicating with their customers, notifying them of the impending shutdown and offering assistance with transitioning to 4G or 5G services. This includes information on compatible devices and potential plan changes.

Vodafone is shuttering 3G services in December 2023, while Telstra and Optus will follow suit in 2024, in June and September, respectively.

When does 3G end in Australia? Take a look at how it affects devices:

How to check if your device is 3G-only?

If you have purchased your device within the last 10 years, then it is likely they are at least 4G-capable. But older devices might not be compatible with Voice over Long Term Evolution (VoLTE), a technology that allows your phone to make and receive calls on 4G networks. Devices bought outside Australia could be affected even if they are listed as 4G-compatible, because their spectrum bands aren’t compatible with Australian networks.

You might be able to check if VoLTE and/or 4G are enabled in your device’s Settings under Mobile Data Options. If the device is able to connect to 4G, it should automatically select this network over 3G where available. If you only ever see the “3G” symbol at the top of your phone or tablet’s screen, your device is likely to be 3G-only.

What if you have a 3G-only phone?

You won’t be able to make calls, send messages, or use the internet when the 3G network is switched off. Many older phones, especially those manufactured before 2014, might not support newer networks. Emergency 000 calls on other 3G networks when in coverage will still be possible. You could also use Wi-Fi to access the internet. However, it is recommended that you upgrade to a 4G or 5G compatible phone immediately.

What other devices are impacted by the 3G shutdown?

It isn’t just older phones that will be affected by the shutdown. Some older tablets, e-readers, security systems, baby monitors and even medical alert devices which use a 3G connection may no longer work after the 3G shutdown. Some devices such as tablets and e-readers with 3G connectivity may still be able to be used, but they will become Wi-Fi only devices.

Is it necessary to change mobile plans?

As of now, there is no need to change mobile, data, or broadband plans once the 3G network downs its shutters. You can still access your service on 4G and 5G networks where available. Don’t worry about keeping your phone number – there won’t be any change regarding that.  However, you may need to update your SIM card, if your old device still uses a mini or micro SIM size. Newer phones and devices require a nano SIM as standard, which is much smaller than the SIM cards used in old phones. If your current SIM is too big for your new device, you can contact your telco’s customer service team to order a nano SIM replacement.

Should Australians upgrade directly to a 5G device?

If you wish to future-proof your new device and get access to some of he fastest speeds available in Australia, you could definitely consider a device with 5G connectivity, in addition to 4G. The 5G-ready devices let you use your telco’s 4G and 5G networks where available, so you can experience faster speeds and less lag when on 5G. This technology is now standard on premium phones from brands like Apple, Samsung and Google, and readily available on affordable devices from almost every major manufacturer. Please keep in mind that once you have a 5G-ready phone, it has to be paired with a 5G-capable plan. Check with your telco to see if 5G is available on your plan.

Steps to check compatibility on 3G devices

Identify make and model

It is imperative to identify the make and model of your device. The information is available in the device settings, on the original packaging, or in the user manual. Different manufacturers and models could have varying specifications. You could also search online by entering the model number, along with “specifications” to know more about its network capabilities. The manufacturer’s website can provide useful information in the form of detailed specifications for their products, including network compatibility data, as well.

Check phone settings

Go to the “Settings” in your device, and search for terms like Mobile Networks, Connections, or Network. Find and select “Network Mode” or similar options, and then look for LTE or 4G.

Talk to your mobile service provider

If you are still unable to get information about whether your device is compatible with 4G or not, talk to your mobile service provider. Give them the device’s make and model number and they will guide you from there.

Use online tools

There are numerous online tools and websites using which you can verify if the device is compatible with 4G. Search for such tools on the internet, and enter the device details to verify its compatibility.

Keep in mind that even if the device is 4G compatible, you need to ensure that your carrier supports 4G services in your area, and you have a 4G-enabled SIM card. If you encounter any difficulties, reaching out to your carrier's customer support is often the most reliable option.

Is 3G still available in Australia? This is a common question on everyone’s mind these days! Even if 3G is still operational, the shutdown is imminent, with Vodafone being the first in December, 2023. However, it means that you can expect improved network coverage and performance as the 3G spectrum is repurposed for newer technologies – you get to experience faster download and upload speeds, smoother streaming, and reduced latency. While it might require a few adjustments, the transition to 4G and 5G networks promises improved connectivity and better performance for both consumers and businesses. So don’t wait any longer – upgrade your devices right away!

Australia is all set to undergo a colossal change as three major players - Telstra, Optus, and Vodafone – prepare for a 3G network shutdown after a couple of decades. The phenomenon, known as “3G Sunset”, is set to take place between December 2023 and September 2024, following which telcos have to repurpose the radio frequencies to support newer technologies.

Is 3G still available in Australia?

The 3G shutdown (Australia) is a huge development for the Australian telecommunications industry that has witnessed the use of 3G technology for a long time. 4G has been the norm for some years, while 5G is making inroads, but many individuals and organizations still use 3G-only devices. The shutdown of Telstra, Optus, and Vodafone’s 3G networks will render some of these devices useless, leading to concerns around consumer choice and potential environmental impact. As of now, 3G networks are still available, but the phasing out is set to start soon, so there could be network disruptions.

Will IoT devices work after the 3G shutdown?

With the imminent 3G network shutdown, businesses with devices that operate on IoT (Internet of Things) platforms could face hurdles. But the good news is that transitioning to other available technologies, like 4G, 5G and 0G can offer a variety of benefits, including improved capabilities, lower costs, and better device management.

So what happens after the 3G networks are completely shut down? The answer is simple – older IoT devices might become inoperable. So, businesses that use IoT devices have to invest in updated hardware and new connectivity solutions. It is estimated that more than 50% of all IoT devices that presently rely on cellular to transmit data and connect to the internet will be affected by the 3G sunset.

3G/4G capable devices would still be able to communicate, but that will be lost if they go outside the area of 4G coverage, due to the lack of 3G backup. Despite this, many companies have delayed upgrading their IoT devices due to the complexity of updating numerous devices and their underlying management architecture. The cost of replacing these devices can be exorbitant, depending upon your businesses, and the transition can be huge challenge for companies that rely on IoT devices. Moreover, there are security concerns related to emerging technologies.

What to do after the 3G network shutdown?

The 3G sunset does pose challenges, but there are several connectivity options for IoT devices and projects that need to be upgraded or replaced. If the IoT devices are connected to the 3G network, it is imperative to be prepared for the 3G network shutdown. The first step is to determine which of your devices are still using 3G technologies and what their replacement options are.

Some devices can be replaced with 4G or 5G compatible devices, but for others, you might need to consider alternative options such as switching to a different type of network like 0G – a low-cost, low-power wireless network designed to send or receive small messages between IoT devices. Of course, you might have to upgrade to a new device altogether.

When does 3G end in Australia?

One of the most frequently asked questions is – When will 3G be turned off in Australia? This 3G network shutdown, or 3G sunset, is the process of phasing out the 3G technology in a given region and replacing it with newer technologies like 4G and 5G. Since 2001, 3G has been the predominant technology for wireless mobile telecommunications, but as mobile network operators move towards more advanced networking capabilities, they have committed to phasing out 3G connectivity.

In Australia, the 3G shutdown is set to happen during the following timelines:

• Vodafone – December 15, 2023.
• Tesltra – June 30, 2024
• Optus – September 2024.

The phasing out of 3G technology is a significant milestone in the evolution of mobile communication technology. It will surely cause some hurdles for IoT-based operations, but in the long run, it paves the way for more advanced and effective connectivity options.

What issues have cropped up?

There are presently two barriers to the transition from 3G to 4G or 5G:

• Lack of awareness about the 3G shutdown – some segments of the Australian market are still in denial or believe the 3G sunset date can be extended.
• Limited technical resources to support it – companies lack the infrastructure and budget to make the switch.

Different companies are at various stages in their transition programs to 4G. For organizations that haven’t mapped out a strategy yet, it is imperative the get started right away. The best planned and executed migrations can take between 12 to 18 months. These projects often require a re-evaluation of the business and technical aspects of the IoT solution. A redesign of the technical architecture could be needed, along with hardware and equipment replacements in the field.

A major issue for machine-to-machine (M2M) projects, has always been the hidden costs of project planning. For instance, 4G might not work where 3G works, antennas purchased to support 3G may not be compatible with 4G, power, and connector specification could be different.  Another consideration is the lead time on hardware, which can take up to six months if sourced overseas.

The transition has to be as smooth and efficient as possible, so there are minimal disruptions in the business and no negative impact on customers. Work out a clear migration plan, understand the requirements of existing and future devices, and choose the most suitable network technology.

Which sectors are going to be affected?

Industrial and manufacturing industries are going to be massively impacted due to the 3G network shutdown. For example, some of them have windmills that connect to the 3G network. They have to be upgraded, before the network is turned off in their region. Failure to upgrade these devices could lead to lost data and decreased efficiency, as they won’t be able to connect to the internet. There is a global shortage of microchips, which has made it even tougher for IoT-based operations to update devices. The transportation sector will be affected too, as IoT devices used to record driving hours, capture real-time location and collect other data will become inoperable.

Let’s face it – the 3G shutdown (Australia) is inevitable, but it is a great opportunity for businesses to upgrade and boost operations. It is best to capitalize on this incredible opportunity, minimize costs, and make businesses future-proof.

Ever since 2003, thousands of Internet of Things (IoT) devices and systems have benefitted from the arrival of 3G in Australia. In the last few years, the network has acted as the backbone of several industries that relied on it to stay connected and transmit data consistently. But with the evolution of 4G/LTE and 5G networks, telcos in Australia have decided to shut down the 3G network, making several devices and systems redundant.

Why are 3G networks being shut down?

This type of shutdown is known as reallocating or re-farming – it happens when a specific mobile radio frequency band or spectrum is repurposed from one technology to another. The reason being that technology is constantly evolving, so people hardly use 3G frequencies these days.

The evolution of the carrier network has two different objectives. The first is to increase data speeds. The second is to better meet the needs of IoT devices, which often only transmit small amounts of data and thus, don’t need high data bandwidth. However, they must have long battery life and greater coverage. For carriers to roll out these new network services, they have to shut down older networks to re-farm the spectrum bands.

3G networks use wideband code division multiple access (WCDMA) technology, which uses the entire cellular spectrum for data transmission. 4G/LTE and 5G use orthogonal frequency-division multiplexing (OFDM) technology, which divides the spectrum into smaller sub-bands or slices for more efficient use. 3G devices can’t communicate with 4G/LTE or 5G towers. As consumer demand for 3G depletes, it isn’t possible for network carriers to maintain and support separate sets of network infrastructure.

Once the 3G spectrum band has been reallocated, it won’t be available to use anymore. Eventually, the spectrum will be improved to 4G/LTE and boosted by 5G later on. Few mobile and mobile broadband devices won’t be able to access the network, or will have limited connectivity. Professional hardware has to be replaced.

What have the Big Three decided?

The major telcos in Australia Telstra, Optus, and Vodafone have announced different timelines to shutdown 3G networks:

Telstra 3G shutdown

The 3G connectivity on its 2100MHz spectrum was shut down on March 25, 2019. However, 3G services will continue on its 850MHz spectrum until June 2024. Consumers who use Telstra MVNOs including Boost Mobile, Belong, and Woolworths Mobile are going to be impacted. As of now, the company is proceeding with the planning and upgrades of its new mobile network and new 4G/LTE coverage. It is even working to repurpose the spectrum that is used for its 3G services and reallocate it to 5G.

Optus 3G shutdown

3G services on the 2100MHz spectrum have been shut down, but the 900Mhz spectrum still has it. All Optus MVNOs including amaysim, Circles.Life, and gomo will lose 3G connectivity, once the 3G is entirely axed in September 2024. The company will contact consumers who are likely to be affected, in order to provide information about upgrading their device, SIM card, or both.

Vodafone 3G shutdown

Here too, there isn’t any 3G connectivity on the 2100MHz spectrum since 2019, but it is available on the 900MHz spectrum. Vodafone plans to switch off the 3G network on 15 December 2023. Vodafone-powered providers such as iiNet, TPG, and Kogan Mobile will lose 3G connectivity. Some 4G/LTE handsets could require a change in settings so they can continue making and receiving calls on the Vodafone 4G/LTE network.

Let us assess the impact of the transition from 3G to 4G/LTE

As of now, Australia has between 2 and 3 million active IoT devices operating on 3G. Apart from key sectors like mining and resources, major users of 3G-enabled devices include healthcare providers, utilities, emergency services and road authorities. Once the shutdown rolls out, all 3G-based devices will cease to operate. It means flood monitoring systems in regional Australia, GPS systems on ambulances, and even traffic signal systems.

Various companies are in different stages in their transition to 4G/LTE. Ideally, these migrations take anywhere from 12 to 18 months. Businesses have to re-evaluate their overall model and technical aspects. It could mean a redesign of the technical architecture, as well as hardware and equipment replacements in the field. The shutdown of the 3G network has its most significant impact on businesses that rely on the 3G network to operate their IoT deployments, including fleet companies, logistics providers, government contractors, and other businesses that use machine-to-machine (M2M) communications. It is crucial for these businesses to understand and properly prepare for the shutdown.

Impact on individual consumers

Most smart devices these days have both 3G and 4G/LTE capability, so your phone should continue functioning like before. But if you are using a 3G only device, then it must be upgraded. 3G will be around till 2024, so you have some time to make the transition. The shutdown is imminent, so take a moment to check your device, and ensure everything is updated and geared up for the future.

Impact on businesses

As technology progresses and new advances replace the old, businesses have to learn, adapt, and embrace the change. Here are some issues that businesses could face:

Compatibility of devices

With 3G devices being discontinued, businesses that exclusively rely on 3G connectivity equipment will face compatibility issues. Upgrading to 4G/LTE compatible devices and routers will be necessary to ensure continued connectivity and operations.

Network congestion

When the transition happens from 3G to 4G/LTE, there will be increased number of users in newer networks. The uptick in demand could cause network congestion, thus impacting the reliability and speed of mobile data connections for businesses during peak usage periods.

Disruptions in services

As telecom providers progressively shut down 3G networks, businesses that depend upon 3G for critical services such as point-of-sale systems, remote monitoring, tracking devices in vehicle fleets, and M2M communications, are bound to face service disruptions. It will unfortunately lead to loss of productivity, customer dissatisfaction, and potential financial losses.

Vulnerabilities in security

Since 3G networks are older technologies, they don’t have cutting-edge security features of their 4G/LTE counterparts. Businesses that still use 3G are definitely exposed to greater security risks. For instance, alarm systems might not work properly, and there could be data breaches and cyber attacks. Upgrading to 4G/LTE networks enhances security measures, protecting sensitive business information.

How can businesses prepare for the transition?

• Assess the present deployments and determine which hardware is compatible with 4G/LTE. The equipment that doesn’t fall under this category has to be replaced.
• Evaluate connectivity needs and determine the required bandwidth, coverage area, and data usage.
• Contact suppliers to begin software upgrades, get an idea of how much the transition will cost, and chalk out replacement hardware. Don’t forget to factor in lead times. You need to conduct thorough research to select a suitable 4G/LTE router that meets your business needs – account for network compatibility, security features, scalability, and management capabilities.
• Test new devices to ensure they are compatible with existing infrastructure. It could involve reconfiguring or upgrading systems. Testing connectivity is a must, along with configuring redundancy features such as dual SIM functionality, so there is uninterrupted connectivity, even during network disruptions.
• Identify all devices and equipment that currently rely on 3G connectivity. Update the network settings on these devices to connect to the new 4G/LTE network.
• Monitor the performance of the 4G/LTE network and devices following the switch. Optimize network settings, such as signal strength and bandwidth allocation, to achieve optimal performance.
• Communicate all changes to staff and impacted customers to minimize disruptions and ensure a seamless transition.

Will other tech be affected?

Apart from smartphones, 3G plays a crucial role in navigation and alarm-based systems in vehicles. Now that 4G/LTE and 5G have made their foray into the market, roadside assistance and emergency crash alerts are among the many network-based features that will be affected by the shutting down of 3G.

While the modification may come in the form of downloadable software or physical spare parts, it will help to keep your vehicle up-to-date.

The shutdown of the 3G network in Australia is certainly a vital milestone in the evolution of its telecommunications infrastructure. In the upcoming months, it will pose several challenges for businesses that still depend upon a 3G network, but careful planning and preparation make the transition to newer technologies more convenient. By assessing their current devices, testing their systems, and communicating changes to their staff and customers, businesses can prepare for the change and continue to operate effectively into the future. Transitioning to 4G/LTE ensures that businesses can maintain a competitive edge in the digital landscape.

In today’s business environment, consumers always look for instant results. A simple example is that when they place an order, they immediately start tracking to see when the package will arrive. In fact, no one will place orders without a definitive ETA (estimated time of arrival). This has drastically changed the last mile for the supply chain industry, forcing operations into making faster deliveries and monitoring more accurately to deliver a product to its final destination.

Companies are struggling to keep up with shipping and tracking – they are looking for new methods to keep up with the increasing pace of last mile. As we become more dependant on technology, it comes as no surprise that digitization is the solution. Once digitization is implemented in the supply chain, it revolutionizes last mile, thus allowing accountability and transparency to meet customer requirements more efficiently. It ensures there is no extra stress on the supply chain, which could cause disruptions.

How can last mile improve digitization of supply chain?

Plan and schedule transportation

When it comes to the last mile of supply chain planning, it means the movement of finished goods from the transportation hub to its final destination. To ensure that this process goes on smoothly, you must plan the transportation properly. Even though transportation seems like the most straightforward aspect of the supply chain, as “the hard part is over”, it can cause loads of issues, if not efficiently managed.

End-to-end efficiency in a supply chain is extremely important for seamless last mile operations. It is clear that with the right transportation optimization software, dispatchers and planners are able to design and optimize the perfect transport scenario. Suitable solutions allow dispatchers to plan and schedule vehicle routing in the network, thus ensuring pickup and drop-off of goods in a timely manner. Using analytics, data integration, telematics, Internet of Things (IoT) , and geo-services, you get real-time forecasts. It provides you with the information required to avoid disruptions and make optimal transportation decisions, both in-bound and out-bound. Thanks to smart, accurate, and timely decisions, planning efforts can be reduced up to 60%, while transportation costs can be minimized by 20%.

Keep in mind that automation of digitization eliminates risk of human error, while allowingsmarter decisions, via use of parallel processing instead of sequential methods. Data is simultaneously analyzed through one system, rather than requiring coordination from numerous team members. It improves internal communication, while easing exchange of information.

With a digitally transformed transportation system, you can be more confident in your goods’ timely movement from one destination to another. 

Keep tabs and monitor in real-time

Apart from reliable transportation, you should be able to track and monitor products as they move through the last mile of supply chain. Multi-dimensional monitoring helps visualize the supply situation, providing transparency when it comes to bottlenecks, inventories, and complete coverage of the supply chain.

While identifying bottlenecks, you can check exactly which orders are affected so you can filter them apart from on-schedule orders and reduce further delays. Moreover, these real-time updates will allow you to update customers as quickly as possible, thus maintaining customer satisfaction.

Monitoring via last mile software solutions help to identify specific problems like bad weather, delays in transportation, and lost cargo, before they even arise. Warnings such as these are critical to avoid disruptions and maintain timely deliveries. This monitoring system keeps tabs on processes in a global environment, be it tracking products by land, air, or sea. It will monitor supply of parts against planned sequence, inventories, and transportation route, ensuring you have eyes on the products at all times. It simultaneously checks your ability to deliver and also the status of products, so the supply chain is up-to-date. Using Anstel’s Last Mile solutions that help to monitor round-the-clock, you can save tremendously in reducing safety stocks and additional transportation trips, allowing you to increase production.

Pay attention to shipping

Transportation and monitoring are two of the major components of last mile, but the primary purpose of last mile is delivering goods to their final destination. Some companies often overlook the importance of their shipping responsibility, falsely perceiving it as being out of a business’s control. In fact, there have been several delays in shipping in the last couple of years due to the Covid-19 pandemic.

While this is an unprecedented side effect, it should not be news for supply chain managers to prepare for the unexpected. To prepare for global delays like this, or even delays of the usual kind, supply chains must have an effective system of managing their shipping process. Digitization of supply chains will help predict delays and quickly resolve them. While it may seem that the solutions for transportation and monitoring overlap with shipping, it is crucial to cover all of your bases.

When it comes to shipping, machine learning has totally transformed supply chains. This is a process where enormous data caches are analyzed to find connections between different sets of information. Shipping involves massive quantities of data, and it can be easy for important details to get lost, resulting in delayed or missing orders. When this happens, business is impacted, which leads to loss of reputation and revenue leakage.

Once machine learning is implemented into the shipping systems, it will use historical data such as past orders, while comparing it with real-time information. It enables standardization of key data points to alleviate some of the complexity of supply chains and last mile delivery. Thus, it pinpoints the factors contributing to a successful supply chain and continues to implement them. Moreover, it predicts forecasts that let you prepare orders, storage and transportation more accurately, thereby simplifying the shipping process and bringing products to consumers much faster. Added awareness of these factors will allow you to maximize capacity and transportation, saving you valuable time and money while exceeding customer expectations.

Keeping customers happy

The last mile is all about bringing goods to their final destination, but you must not forget what that destination is – customers. The ultimate goal of your supply chain is to maintain and improve customer satisfaction, while encouraging repeat business. By digitizing the supply chain, you provide customers with timely, rapid, and reliable deliveries. Implementation of transportation planning systems, multi-dimensional monitoring, and machine learning, ensures an excellent supply chain performance, which means happy customers at the end of the day. Customers get real-time updates thanks to last mile solutions, regarding order status. They know just what to expect when they conduct purchases. While digitization is crucial for your supply chain and will benefit you in countless ways, it is essential to remember that it is advantageous for customers too, especially in the last leg of their anticipated delivery.

How can transitioning towards digitization help?

Due to volatility of demand and irregular product availability, stock-outs are amongst the biggest challenges being faced by last mile delivery companies these days. Customers have little patience or tolerance when they hear their favorite item is unavailable. It will take seconds for them to switch to a competitor when they encounter a stock-out. After all, there are many active players in the last mile delivery environment. 

High seasonality, short shelf-life, and the perishable nature of many products require a lot of precision in purchase order planning. When you work with a trustworthy digital transformation partner, it helps to accurately forecast future demand and product availability, so you can dynamically adjust stock levels to find the right balance between minimizing stock-outs and eliminating waste.

Remember that due to aggressive growth, last mile delivery providers have an incredibly complex network of warehouses, docks, dark stores, and local vendors, usually without adequate planning infrastructure. They usually have limited planning tools and rely heavily on employees for knowledge management. Add to that the abundance of spreadsheets for individual processes, and it is not hard to get lost in the chaos. 

Thanks to digitization, machine learning, and advanced analytics, last mile providers can effectively plan all steps of their supply chain journey. It includes forecasting, dark-store replenishment, and warehouse procurement – each step is integrated seamlessly with one another and works in sync to deliver amazing customer service. They can consolidate their entire supply chain network under a single digital platform. The system considers external factors such as weather data, special events, and promotions from various sources to generate actionable insights and automated recommendations to run their dark-store replenishment and warehouse procurement processes. 

By utilizing cutting-edge technologies and analytics, last mile providers can survive the ever-demanding challenges of fast growth. Digital supply chain planning solutions offer sophisticated tools to tackle these predicaments rigorously. 

The Covid-19 pandemic showed us what it takes to find innovative solutions during challenging times. Supply chains have to maintain stellar performance so companies can continue delivering exceptional customer service, while ensuring their product offerings are accessible, convenient, and fully available at all times.
