1 GENERAL INFORMATION
The mBDA Digital Band Selective Repeater
(hereinafter called
“mBDA”) is designed for a single network
system, like 850MHz, 900MHz, 1800MHz, 1900MHz, AWS, 2100MHz or 2600MHz etc. It can wireless
transmit, three-way amplify BTS uplink and downlink signals and enlarge coverage range. Digital band
selective technology effectively amplifies the desired BTS signals and provides superior out-of-band
rejection, avoid cell interference and improve call quality.
Main Features
Wideband digital processing technology, instant operation bandwidth reaches 25MHz for GSM, 20MHz
for LTE and 15MHz for WCDMA.
It supports three wideband channels; each channel can turn off separately. Operation band is
0.2-25MHz adjustable for GSM, 3-20MHz adjustable for LTE, and 5-15MHz adjustable for WCDMA.
High power bandwidth linear PA ensures signals no distortion amplification.
The system gain is compensated automatically according to the temperature variation within the
enclosure, which ensures stable operation under ambient temperature.
Has off-line isolation testing, downlink VSWR alarm, downlink input filed intensity and output power
testing function, which is convenient for installation and commissioning.
Supports multi-band expansion, convenient for configuration and upgrade.
Remote software upgrade is available.
Local Web Operation and Maintenance Terminal (Web-OMT): operating status and parameters can
be set or monitored by PC locally.
Operation Maintenance Center (OMC): system working parameters and communication configuration
can be set or inquired remotely through the build-in WCDMA modem. If alarm is generated, the
equipment will dial up to OMC automatically.
Build-in Li-ion battery ensures that alarm information can automatically report to OMC in case of
equipment power failure.
Designed for all weather installation
– waterproof, damp-proof and omni-sealed.
