Will 4G Cell Phones Work on 5G Networks? Everything You Need To Know

by Rhydian Choi

It’s no secret that the world of mobile technology is advancing quickly, with new generations of networks and phones being released seemingly every day. Now that 5G networks are beginning to become available, many people are wondering: will 4G phones work on these networks?

There are several factors to consider when making the decision to switch over to a 5G network. This guide provides an overview of what 4G and 5G network technologies entail and explains how they differ, covering both their respective benefits and drawbacks. Additionally, it provides different scenarios related to the compatibility between 4G and 5G phones-— discussing whether investing in a new phone or sticking with your current one is the best option for you.

The difference between the two networks

Although these networks both utilize the same type of cell towers, the technology is significantly different. With 4G, the data rate is designed to support both data and voice services; with 5G, it’s designed to support much higher bandwidth and faster speeds.

4G networks are capable of supporting a maximum transmission speed of a little more than 150 Mbps, while 5G networks have theoretical maximum speeds of around 10 Gbps. In addition, 5G also makes use of shorter-range radio frequencies—as low as 6 GHz—which allow for more localized traffic access and lower latency.

The physical layer design in 4G and 5G networks will also be distinct. In the case of 4G networks, lower frequencies (2-6 GHz) are used where larger cell sizes are operated over large distances; while at higher frequencies (6-14 GHz), coverage is much more local but operates over smaller distances. On the other hand, with a 5G network these two frequency ranges overlap to provide better coverage for both local and metropolitan areas.

The answer is both yes and no. Generally speaking, 4G phones can access 5G networks, but it will depend on how the networks have been upgraded and which frequencies they use. Most operators in the United States offer services over two frequency bands: sub-1GHz (low bands) and mmWave (high bands).

4G devices that only support sub-1GHz will be limited to 5G speeds up to 1 Gbps — significantly faster than the current LTE capabilities of up to 400 Mbps with many 4G networks. By comparison, 5G mmWave devices are noticeably faster with peak download speeds of 6-7 Gbps or higher depending on coverage levels and distance from a base station or tower. Unfortunately, 4G phones cannot access these ultrafast mmWave frequencies — they simply don’t have appropriate electronic components such as antennas that can operate at those incredibly high frequencies.

The bottom line is this: if your device has a radio transceiver specifically designed for the millimeter wave spectrum then it should be able to access a 5G network and enjoy those high speeds. Otherwise, your device may use some combination of existing 3/4 G tech over whatever spectrum is available — which may not necessarily offer much improvement over existing speeds offered by your current provider.

Benefits of 5G

The move to 5G technology promises faster download and upload speeds, providing users with a more reliable mobile internet connection than ever before. The new networks are designed for low latency, which means fewer delays when loading content on your device. This can make all the difference if you’re streaming video or trying to complete an online transaction quickly. Other benefits of 5G include:

-Increased Network Capacity: 5G will allow more connections at higher speeds, allowing more people to use the same network while maintaining rapid connection speeds.

-Better Security: 5G networks will be secured by CommScope’s Dynamic Spectrum Access technology that automatically identifies and blocks any unauthorized connections in real-time. This will increase user security and reduce the risk of malicious attacks on the network. To add up, privacy and data protection are essential, and features like that are offered by companies like https://policy.zte.com.cn/.

-Advanced Connectivity: Thanks to flexible layers that support cutting-edge technologies such as mmWave, Edge computing, and Wi-Fi offloading, users are likely to experience a much faster response time when connecting to the web. For businesses, this could translate into increased operational efficiency from improved data transfer speeds and greater reliability from low levels of latency.

What are the challenges?

The transition to 5G technology brings with it many challenges as this next generation of cellular networks is more complex and requires the development of new infrastructure. The following are some of the major challenges that must be addressed in order to make this transition a success:

Signal interference: 5G radio frequencies operate at very high frequencies, which makes them more susceptible to interference. This will require a far more sophisticated antenna system than was used for 4G or earlier networks and will also require much tighter frequency control, or else performance will suffer.

Costs: The increased capacity of these networks comes at a price – both financial cost and power consumption. Deploying the necessary equipment and infrastructure demands significant investment from all sides. Additionally, the large number of antennas used by 5G networks require a great deal of power, making the economics of transitioning from 4G highly dependent on the availability of low-cost power sources such as renewable energy sources.

Spectrum shortage: One issue in establishing 5G networks is that there may not be enough spectrum for data traffic to flow properly. This is due to multiple competing technologies trying to share available spectrum resources, which can cause congestion and delays in data transmissions. Governments are attempting to address this issue by making additional spectrum available through auctions but this has caused frustration among network providers who have been forced to pay higher prices for spectrum rights than they had originally anticipated

Latency: Latency refers to how long it takes for signals on a 5G network to reach their destination and is an important factor when it comes to ensuring seamless connectivity between devices. Low latency is critical for having devices such as self-driving cars interact with one another in real-time; anything slower than 15 milliseconds will cause problems with these types of applications. Unfortunately, current technologies do not allow for latency lower than about 30 milliseconds, so significant improvement must be made before true 5G technology can become viable.


While many changes come with the switch from 4G to 5G, the primary takeaway is that more advanced speeds and lower latency levels are now possible. This means that users can access greater speeds for activities such as downloading files and streaming videos. In addition, businesses can use 5G to develop new products or services that require faster speeds than what was once possible with 4G.

Ultimately, if you are considering getting a new smartphone for use on the latest 5G network, you should make sure that the model is specifically designed for this purpose and has the
