BS422 innovative outdoor base station
Description
BS422 is a multi-carrier, multitechnology outdoor base station. The base station is a supplement to DAMM’s current portfolio of TETRA base stations, by being much more than just a TETRA base station.
It can operate up to four logical carriers, each in any technology mode:
• TETRA
• DMR Tier III
• DMR Tier II
• Analog
• TEDS (TETRA Enhanced Data Service)
at the same time, any combination.
With the BS422 one single base station can contain one TETRA, one DMR T2/T3, one TEDS and one Analog logical carrier or any other mix, enabling seamless communication across these technologies.
As a single-carrier setup, it is possible to connect up to eight BS422 base stations at one site (node), each running TETRA with full 25W output power, offering up to 31 simultaneous traffic channels and one master control channel. As a dual logical-carrier setup, this will be 16 TETRA carriers with 10W output power and 63 traffic channels and one master control channel.
This base station is designed to be placed close to the antennas without any additional visor and that saves installation and maintenance cost.
