OPERATIONAL DESCRIPTION OF THE BS422
The BS422 has all the RF circuitry required for a completely self-contained base station. Its main RF components are outlined in Chapter “BS422 main components”.
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.
Hardware
The BS422 is a compact single-box unit with build in duplex filter.
The concept is based on a decentral architecture, which means that no further components like servers or switches are needed. All features for a functional trunked radio system is build into the BS422. The basestation is designed for direct outdoor mounting.

Environmental / climatic requirements
The Base Station is designed for outdoor operation, such that it can be placed in the antenna mast close to the antennas.
The Base Station is designed to be able to operate at severe environmental conditions.
The Base Station is guaranteed to operate under ambient air temperatures from –25°C to +55°C Celsius. Maximum BS422 cabinet temperature is +85°C. Storage temperature for the BS422 is from –40°C to +85°C.
Note that the guaranteed MTBF data is valid only within the standard specified temperature range Screening of BS422 to specific customer-defined temperature range (from -40°C to +55°C ambient air temperature) is optional upon request.
The Base Station encapsulation complies with IP65
Placement
The recommended placement of the Base Station is as close to the antennas as possible to reduce cable loss. The placement of the Base Station shall be such that it is securely fastened to a mast or building that is able to carry the weight of the BS422 and withstand the local environmental conditions. All cables, antennas etc. shall be properly fastened to the mast or building using appropriate fixtures as to avoid damage to the equipment and possible injury to persons.
Grounding
The BS requires careful grounding.
Grounding is important to protect the equipment when inserting/removing cables and to protect the operator from faulty equipment.
An effective grounding is also important to protect the installation during thunderstorm (lightning).
The grounding shall be as specified in paragraph “1.2.6 Power connection to SB422”
