Rail WiFi AES Systems 

The WiFi-5/6 train-to-ground DAS/AES systems consists of multiple subsystems, support for speed of a train typically ranges from 80 - 120 km/h, enable 100MHz - 6000MHz RF over fiber with BiDi operational.  

According to the demand of customer,we think a clearly system application diagram is needed so as to avoid misunderstand.Above diagram is what we understand of the scenario. A trackside AP's RF PORT is connected with a MASTER through RF cable,MASTER finish the O/E and E/O convertion and divide one port signal to 4 port optical signal, one MASTER can connect 4 SLAVE sites through fiber not more than 1.5km.Every SLAVE finish O/E and E/O convertion and connect a panel atanna.

SLAVE atanna’s coverage area is AP in front and rear of the train.
