Airbridge cBTS3612 CDMA Base Station
Current equalization hot backup, centralized management, and decentralized power
supply are enabled. It makes the power supply system safer and more reliable. It
provides automatic alarming through monitoring interface for the power fan, input
under-voltage, output over-voltage, overheat and protection against reverse
connection. This ensures the reliability of the power system. Remote power on/off
function enables unattended BTS operation and remote maintenance.
1.2.6 Multi-band supported
Now the cBTS3612 base station support the following band class specified in
TIA/EIA-97-D Recommended Minimum Performance Standards for cdma2000
Spread Spectrum Base Stations.
Band Class 0 (800 MHz Band).
Band Class 1 (1900 MHz Band).
Band Class 5 (450 MHz Band).
To support the different band classes, RF modules with different specifications
should be configured in cBTS3612 base station.
