As the world embraces the newest mobile technologies, it’s important to understand the distinction between 4G, which was the norm in the 2010s, and 5G, which is shaping the future of mobile. Knowing the differences between the two will help you learn the benefits of 5G, and how it can provide faster and more reliable service.

What Is 5G vs 4G Mobile?

4G and 5G refer to the generations of cellular telecommunications technology. The way that your phone communicates with other devices—and the Internet—is governed by the technology it’s using. Everything comes down to which “G”, or generation, you’re running, including call quality and browsing speed. Generally speaking, each new generation boasts exponentially improved tech than the last. So, if you want to be streaming, chatting, texting, and browsing at your best—5G is the way to go.

What Are the Benefits of 5G?

Both 5G and 4G utilize similar technologies that transmit based on radio signals. The difference lies with 5G’s ability to use a wider range of frequencies, allowing data to travel stronger and faster. 5G is also more efficient because its technology allows it to reach people with less clogging and slow-downs.

The table below shows a breakdown of differences between 4G and 5G performance. It includes the following info:

Average download speed: These are the speeds that we see in the real world for each network. The speeds represent how long pages, files, and other data take to download and install.

Latency: Information is sent in “packets” from one point to another. Latency is the average time it takes for that information to be sent and received.

Bandwidth/Capacity: Networks operate within selected frequency ranges. The capacity of a network is how much room it has in those ranges for all phones and devices to utilize. If one device is taking up too much bandwidth, then another device will have slower speeds. More bandwidth equals more room for high speeds for everybody.


Average Download Speed35 megabits per second (Mbps)50 Mbps to 3 gigabytes per second (Gbps)
Latency50 milliseconds10 milliseconds
Bandwidth/CapacityLimited to 600 MHz–2.5 GHzSubstantially more capacity across three different ranges
AvailabilityMore readily available across the countryStrongest in large cities and currently rolling out nationwide


5G has the advantage over 4G in all performance categories, meaning you can do whatever you need, faster. 4G is still available in more places nationwide as 5G spreads from large cities. However, because 5G has more bandwidth and also more frequency bands, there will be more types of 5G so that people in all areas can eventually take advantage.


Is All 5G the Same?

In short: no. In fact, 5G technology has greater variation than any previous generation. One of the reasons is due to 5G being able to operate in a wider range of frequencies. Whereas 4G works within 600 MHz to 2.5 GHz, 5G actually has three main ranges: low, medium, and high band frequencies. Because of this, devices and operators will be able to offer and reach people in different ways depending on their location and service plan.

When it comes to providers, the same idea goes: not all providers are the same. Some operate on different frequency bands, and others are still working on their 5G service plans.
