Since the rise of the internet and smartphones, internet networks, popularly known as 3G, 4G or 5G, is progressing and improving every year. But what changes between them?
The main improvement is higher download rate in each new generation of networks. For example, with 3G, we were able to send messages via the internet, with 4G, we can download and watch streaming services from anywhere with a signal and, with 5G, it will be possible to connect things, the famous Internet of Things (IoT).
The 3G network began to be used in mid-2002 and is the network with the highest coverage in the national territory. Then, in 2018, came the 4G network, with a higher speed, but without coverage throughout the country. And now, we will have the 5G network.
To understand what changes in each of the generations, it is necessary to understand two concepts that are present in all of them: latency and transmission speed.
Ping
The first concept to be explained is latency, which is nothing more than the response time between an action and its reaction. Latency and speed are inversely proportional: the lower the latency, the higher the speed. Latency is very important when using the internet for certain commands.
For example, an autonomous car needs very low latency so that, when it detects an object on the road, it can break before hitting it. That's why it's only with 5G that IoT must have full force to become more popular.
5G networks have a much lower latency than 4G networks. As stated before, scholars indicate that the response between information sent and its execution (latency) using 5G Will it be close to that of a human or even faster, helping to implement autonomous objects such as cars, robots, among other things.
Transmission speed
As mentioned in the previous topic, speed and latency are inversely proportional. So, in order for us to have low latency, the speed must be high.
Speed is one of the main changes we can see when moving from a 3G network to 4G, for example. The 3G network operates with 8Mbp/s (Megabits per second), 4G, with 28Mbp/s, and 5G promises to be up to 10x faster than 4G.
Thus, a higher speed means that more data can be transmitted and received. It is this difference that allows generations of networks to perform different tasks.
