Hi,
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?
I am asking because I would like to use a nanoBTS-Booster with the multi-TRX
setup and therefore require a combined RF signal.
I'm not entirely sure, but I think that's just the reference clock ?
But in any case you can use splitter / combiner for both the RX and TX path.
You will loose 3dB on the RX path because of the split but that might
be ok with you if you have a LNA before hand anyway.
2. The example example "openbsc.cfg"
configures the trx 1 as follows:
timeslot 0
phys_chan_config CCCH+SDCCH4
timeslot 1
phys_chan_config SDCCH8
No, all TCH should work fine.
Cheers,
Sylvain
