Downlink:

The BTS receives data from BSC, including voice and signaling data.

The transmission unit sends signaling data to the operation & maintenance unit for processing.

The voice data are then sent to baseband processor for processing of rate conversion,

encryption and interleaving.

Data are then sent to RF unit for modulation to high-frequency signals.

Finally, data are then transmitted through the antenna feeder processor.

Uplink:

The antenna feeder processor receives the RF signals from the MS. It then sends these signals to

the RF unit to convert into digital signals. The signals are then transmitted to baseband processor for rate signals conversion, decryption

and de-interleaving.

After conversion to the code pattern, suitable for long-distance transmission, the signals are

sent to the BSC through the Abis interface.
