Re: nanoBTS multi-TRX setup

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
