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.
