- Enhanced Mobile Broadband (eMBB): Seamless video streaming, online gaming, and cloud computing.
- Massive Machine-Type Communications (mMTC): Low-power, wide-area connectivity for IoT devices.
As 5G continues to spread, it’s natural to wonder about the fate of 4G. Will it be phased out entirely, or will it continue to coexist alongside its newer, flashier sibling?
The Current State of 4G
Despite the emergence of 5G, 4G remains the dominant wireless technology globally. According to a report by the Global mobile Suppliers Association (GSA), as of 2022, there are over 10 billion 4G subscriptions worldwide. This accounts for approximately 55% of all mobile subscriptions, with the remaining 45% split between 5G, 3G, and 2G.
In many regions, 4G networks are still being expanded and upgraded to support growing demand. In the United States, for example, Verizon, AT&T, T-Mobile, and Sprint continue to invest in their 4G LTE networks, with some networks boasting speeds of up to 1 Gbps.
However, as 5G adoption accelerates, it’s becoming clear that 4G’s days are numbered. Network providers are increasingly focusing on deploying 5G infrastructure, with some, like South Korea’s KT Corp, already planning to shut down their 4G networks entirely.
Why 4G is Being Phased Out
Several factors contribute to 4G’s gradual decline:

As 4G begins to fade, what does this mean for consumers?
Device Compatibility
For those still using 4G-only devices, the phasing out of 4G networks may render their devices obsolete. Fortunately, most modern smartphones are 5G-capable, ensuring a smooth transition to the new network.
Network Speeds
In areas where 5G has been deployed, consumers can expect significantly faster data speeds and lower latency. However, in regions where 4G remains the primary network, speeds may remain the same or even decrease as networks become increasingly congested.
Pricing and Plans
As 5G networks expand, network providers may offer new pricing plans and promotions to incentivize adoption. This could lead to more competitive pricing and innovative data plans.
The Future of Wireless Networking
As we look to the future, it’s clear that 5G is the future of wireless networking. While 4G will likely continue to exist in some form for the foreseeable future, its days as the dominant technology are numbered.
6G on the Horizon
Research has already begun on 6G, the next generation of wireless technology. Expected to offer even faster speeds, lower latency, and increased capacity, 6G promises to revolutionize the way we interact with the digital world.
As we hurtle towards a 5G-dominated future, it’s essential to stay informed about the latest developments in wireless networking. While 4G’s demise may be inevitable, its legacy will live on, paving the way for the next generation of wireless technologies.
In conclusion, the writing is on the wall: 4G is being phased out, making way for the faster, more efficient, and more capable 5G. As consumers, it’s essential to stay adaptable, embracing the changes that this new era of wireless networking brings.
What is the 4G sunset?
The 4G sunset refers to the gradual phase-out of 4G wireless technology in favor of newer, more advanced technologies such as 5G. This process has already begun in some countries and is expected to continue over the next few years. The sunset period will involve a transition from 4G to 5G, during which 4G networks will continue to operate alongside 5G networks, but will eventually be shut down.
The 4G sunset is not a sudden event, but rather a gradual process that will allow users to adapt to the new technology. During this period, users will be encouraged to upgrade their devices and plans to take advantage of the faster speeds and additional features offered by 5G. The exact timeline for the 4G sunset will vary depending on the country and region, but it is expected to be complete by the mid-2020s.
When will the 4G sunset happen?
The timeline for the 4G sunset varies depending on the country and region. In some countries, such as the United States, the 4G sunset is already underway, with some carriers having already shut down their 4G networks. In other countries, the process has not yet begun, but is expected to start in the near future.
It’s difficult to predict exactly when the 4G sunset will happen, as it will depend on a variety of factors, including the pace of 5G adoption, the availability of 5G devices, and the development of 5G infrastructure. However, most experts agree that the 4G sunset will be complete by the mid-2020s, with some countries potentially completing the transition earlier or later than others.
What will happen to my 4G device during the sunset?
During the 4G sunset, users with 4G devices will likely experience a decrease in service quality as 4G networks are shut down or repurposed for 5G use. In some cases, users may experience service interruptions or complete loss of service, particularly in areas where 5G coverage is not yet available.
It’s likely that users will need to upgrade their devices to 5G-compatible devices in order to continue receiving service. Carriers may offer incentives or promotions to encourage users to upgrade, such as discounts on new devices or plans. Users who do not upgrade to 5G devices may be left without service or may be forced to use older, slower technologies such as 3G or 2G.
Will I need to buy a new phone during the 4G sunset?
It’s likely that users will need to upgrade their devices to 5G-compatible devices during the 4G sunset. This is because 4G devices will not be able to connect to 5G networks, and will eventually become obsolete as 4G networks are shut down.
However, it’s not necessary to buy a new phone immediately. Users can continue to use their 4G devices until the 4G sunset is complete, or until their carrier notifies them that their device is no longer supported. At that point, users will need to upgrade to a 5G-compatible device in order to continue receiving service.
What are the benefits of 5G over 4G?
The main benefits of 5G over 4G are faster speeds, lower latency, and greater capacity. 5G networks are capable of delivering speeds of up to 10 Gbps, compared to the maximum speeds of around 100 Mbps offered by 4G networks. This means that users will be able to download movies, games, and other content much faster, and will experience less lag and buffering.
In addition to faster speeds, 5G networks offer a number of other benefits, including greater capacity, which means that more users can be connected to the network at the same time without experiencing a decrease in service quality. 5G networks also offer lower latency, which means that data transmits more quickly, and is particularly important for applications such as online gaming and virtual reality.
Will 5G be available everywhere during the 4G sunset?
It’s unlikely that 5G will be available everywhere during the 4G sunset. In fact, 5G coverage is still limited in many areas, and it may take several years for 5G networks to reach the same level of coverage as 4G networks.
During the 4G sunset, users may experience service interruptions or complete loss of service in areas where 5G coverage is not yet available. In these areas, users may be forced to use older, slower technologies such as 3G or 2G, or may need to rely on Wi-Fi connectivity.
What does the 4G sunset mean for IoT devices?
The 4G sunset has significant implications for IoT devices, which often rely on 4G connectivity to operate. As 4G networks are shut down, IoT devices will need to be upgraded or replaced in order to continue functioning.
This could have significant consequences for industries such as manufacturing, logistics, and healthcare, which rely heavily on IoT devices. Companies may need to invest in upgrading their IoT infrastructure, which could be costly and time-consuming. However, the shift to 5G could also bring new opportunities for IoT devices, such as faster speeds and greater capacity, which could enable new use cases and applications.
