Today we won't just see what the mobile networks. But also how they work and what types exist. Join me in this extensive article where we talk in detail about each of these points, which you can extend by knowing the main differences between 4G and 5G networks.

What are mobile networks?

It is, in short, of a communication system between the control panel and the devices that connect to it. In this case it would be between the mobile device and the telecom company.

To sum it up a bit, it's about connecting elements like communication towers or antennas and mobile devices. Networks operate over a geographic area generally installed in networks.

In this way and depending on the estimated number of people who will use the service. An infrastructure of communication towers is installed so that the user can use their device and the information they send is received by another person.

How does a mobile data network work?

Communication between mobile devices works by sending and receiving low-power radio signals, a process that is explained by how wireless networking technology works. They travel to several nearby points, they can "jump" from one antenna to another until they reach their destination.

When we make a phone call, what happens is ours cell phone starts looking for coverage. If we have it, a connection is created between our mobile phone and the nearest tower or telephone station to establish the call.

It just doesn't work that way for calls. But also with SMS and the Internet.

Types of existing mobile networks

2G o GSM

Many surely remember using the 2G connections on their mobile devices. This connection is the first for fully digital cell phones. For little things like sending WhatsApp, communicating by voice, etc. It didn't work badly at all.

However, when we tried to browse or work with a larger data stream it obviously got too slow as this type of network is limited to 900 bits per second.


It's about the network 2.5G and It is born to try to solve the serious problem of sending unswitched data. In terms of speed, the change was noticeable as we are talking about 56000 bits. Also being able to reach 144.000 bits per second.


It's about the network 2.75G which practically passed without pain or glory to say the least. Obviously the speed was increased in every way, especially when we were close to an antenna.

3G (UMT)

Popularly known as 3G, the change brought about by this network was well known. The data connection was up to 384.000 bits per second. Which allowed you to browse the internet more smoothly and also perform tasks like video calling.

The way it works is basically to prioritize devices that are close to the antenna while those that were further away were in the background. Surely on many occasions you have heard that to save battery it was better to keep the 2G connection, rather than the 3G one.

It certainly required more power to use 3G, which was reflected in the battery drain.

4G (LTE)

The fourth generation is really fast. Works with the orthogonal frequency division multiplexing and it solves everything that 3G coverage could not. It remains constant no matter how much there is, which gives it impressive stability.

With a 4G connection, browsing sometimes becomes much faster than when doing it with a Wi-Fi connection. Although again it requires more power to run.

5G (IMT-2020)

5G promises to be a real madness in terms of speed since it is a trivial capacity of 100 Mbps. 10 Gbps if certain conditions are met.

If you want to know more, you can consult our guide on what the 5G network is and how it works, so that you really understand what this new 5G network is about.
