Functions

BTS functions as a bridge connecting mobile stations to BSC in the CDMA
system. Details are given below:

BTS communicates with MS (mobile station) through a CDMA air
interface.

BTS communicates with BSC (Base Station Controller) through an Abis

interface.

In the forward link, BTS first receives data from BSC through the Abis

interface, then encodes and modulates the data, next converts
baseband signals into radio frequency signals, finally transmits them

through a power amplifier, the radio frequency front end (RFE) and an
antenna.

In the reverse link, BTS first receives weak radio signals through the
antenna feeder and RFE. The signals then undergo low noise
amplification, down frequency conversion, and decoding and

demodulation. Finally, BTS sends the data through the Abis interface to
BSC.
