BS422
The BS422 has all the RF circuitry required for a completely self-contained base station. Its
main RF components are outlined in Chapter
The BS422 is a multi-technology basestation that is based on a Software Defined Radio,
which enables it to operate several different radio technologies:
TETRA
TEDS
DMR Tier 3
Analog PMR
Each BS422 can operate up to four different carriers simultaneously, independent of the
selected radio technology, inside a defined band.
The different carriers may operate in different bandwidths depending of the selected
technology.
