CDMA 800MHz Wideband Repeater SERIES
Brief Introduction:
CDMA wireless repeater is the transferring equipment for radio transmission, functioning as amplifier in the process of CDMA
mobile communication, as it includes broadband/band selective repeater, selective frequency repeater and frequency shift repeater.
CDMA wireless repeater can serve as the signal resource for indoor cover system as well as for other areas, such as areas without
optical fibers and outdoor signal blind area on the verge of the signals coverage.
CDMA broadband/selective band repeater is the one working for all-band frequency and some frequencies. CDMA selective
frequency repeater refers to one or more repeaters of CDMA allocation channels in all-band frequency or some bands, whose
specifications of 1W、2W、5W、10W、20W.
Highlight Features
