The ZXMBW E9200 processes the following basic traffics:
Forward traffic: The forward traffic from the core network
sends IP packets to the ZXMBW E9200. After decrypting and
unpacking these IP packets, the ZXMBW E9200 CPU control unit
transmits them to the baseband processing unit for encoding
and modulation. The modulated signals are sent to the RF
processing unit for up conversion. After being processed for
power amplification, these signals are transmitted through the
antenna to user terminals.
Reverse traffic: the antenna of the ZXMBW E9200 receives the
signals from user terminals. The RF processing unit performs
down conversion for these signals and then sends them to the
baseband processing unit for channel demodulation. Afterwards,
the CPU control unit converts these signals into IP packets and
encrypts them, and then sends them to the core network
through the transmission network.
