GSM850/GSM900
|
|
The MCPA is designed to expand signal coverage through enhancing the uplink receiving sensitivity and amplifying the downlink signal strength in the area where call drops and handoff failures happen frequently.
It is installed on the top of telecommunication tower and below the BTS antenna to amplify the mobile signal via a low-noise amplifier before the signal is transmitted to the BTS.
