By 5G we mean the fifth generation of a mobile phone standard and a communication protocol. It uses radio frequency bands of the electromagnetic spectrum but the specific allocations differ from country to country.
By 5G we also mean everything related to 5G:
- all devices connected to the 5G network (mobile phones, connected things, antennas, satellites...)
- radiation produced during the communication
- the processing of the data transmitted via this protocol.
On many places in our documents we mention 5G as we prefer to use the widely known phrase - 5G but one may also read 4G, 6G and so on.
Basically, 5G technology builds on the existing 4G system and in the first expansion phase (FR1) it uses only a slightly extended frequency range compared with 4G, up to a maximum of 6 GHz. The main difference here compared with 4G is the use of new types of antennas that can be targeted and thus enable a more effective data transmission with a higher performance.
The second 5G expansion phase (FR2) is still largely in the planning stage and is going to use significantly higher frequencies between 26 and 80 GHz (milimeter waves). However, since the coverage range decreases as the frequency increases, the transmission masts will have to be installed much closer together. This also significantly increases the number of masts and small cells required.
