As the current frequency bands used by the 4G network become congested, the 5G network will have to take up new frequencies.

There are three frequency bands used by the 5G network. Different frequencies also support different uses.

  • Sub-gigahertz frequencies offer a wide geographical coverage. IoT devices use this frequency.
  • The 3-6 GHz frequencies will bring significant additional capacity.
  • Frequencies above 24 GHz will allow for increased speed, as well as bringing further capacity.

With three frequency bands, 5G will mean a much denser network of base stations in the future.

In the current situation, the signal from the base station carries information from the outside to the inside. However, the millimetre frequencies introduced by 5G will not pass through walls. Since a radio link needs a direct connection to the terminal at millimetre frequencies, an internal network of several antennas is needed.

Using three different bands, 5G is not a single network, but rather a network of different networks. The current 4G will remain alongside it for a long time to come.
