1. What is the purpose of the "RF cable"?
Is the TX port of the master BTS looped through the second BTS? Or hase
every nanoBTS his own TRX/RX?
The RF cable is used to route TX from the rear unit to the AUX connector
of the front unit. The SMB socket at the back and AUX are directly connected,
there is nothing special about them. So in a stacked two-units assembly
the front unit also has the TRX antenna of the rear unit at the AUX connector.
Most certainly the idea is to improve transmission of the rear unit or to
better separate the two TRX antennas.
So TX is looped through one unit but the two TX signals are not combined.
Thank you. This made it clear. I thought about the same setup but was
hoping that the TRX signal is combined.
Any idea what the NWL connector is for?
Best regards
Konrad
