When we talk about 5G, we are referring to a specific mobile connection standard which corresponds to a very high speed in both download and upload in order to be able to be used for the widest possible range of uses and devices.
However, taking a step back, we know that mobile connectivity has changed a lot over time and we can now use 3G or 4G (or LTE) networks on most parts of the planet.
This latter connection type, 4G, is already characterised on its own as extremely high performance and it is often faster than many household networks with ADSL technology, in the absence of fibre optics. One of the things that can be done with this type of speed is viewing HD videos and downloading files minimising latency.
So what does 5G have that is so different from this technology?
The factor that will set 5G apart from other communication standards is naturally the connection speed. Basically, what will change in common use will be having a data connection as much as 1000 times faster than the current 4G. This is a value that will make use much more vast than it is now.
Another thing that will change will be the technology around us. Devices belonging to the world of IoT (Internet of Things) will be implemented more and more, so terminals perpetually connected to the network: washing machines, coffee machines, virtual assistants, home automation devices.
In order to work, these devices will need an increasingly faster data connection with protocols that demonstrate its performance and security.
A bit of history: mobile connections
There have been different mobile connections available over the years. If we want to go back through history, we need to go back to 1991, when “1G” connectivity was born.
It was a protocol that only allowed telephone calls but which, in its historical context, was already an enormous step forward.
Then 2G appeared which, with its protocols like GSM, made it possible to send SMS text messages too. On the other hand, 3G, a technology that is still in vogue today, allowed data exchanges in increasingly greater volumes and at a more reasonable speed, guaranteeing an actual mobile connection to the Internet.
4G finally allowed all of this enormous data and information exchange to be done at an even higher performance and it is now the protocol used in the areas of the world with the greatest connection possibilities.
5G will make everything even faster, obviously, but how?
It will happen with a distribution of the network, making it so that it uses an extremely high number of antennae and cells in order to make the signal between them even more available, thereby avoiding fibre optics and the problems connected to it.
However, we will still need to wait another year or more. The first telephones that will be compatible with the 5G network will be on the market between 2019 and 2020, to then expand.
