The question is - is there any difference between multiplexed and non-multiplexed mode for osmo-bts-trx config file? I've got multiplexed mode working with following setup: ...
phy 0 instance 0 instance 1 ...
trx 0 phy 0 instance 0 trx 1 phy 0 instance 1 ...
I used the same configuration.
Should it look differently for non-multiplexed mode? Are there some other command-line options or config files adjustments missing to make non-multiplexed mode working? Did I got the overall setup right?
Multiplexed and non-multiplexed configurations should look the same to osmo-bts. The main difference will be on ARFCN settings.
Multiplexed (MCBTS) - TRX0 is the primary ARFCN. Channel spacing is fixed at 4, so TRX1 and TRX2 must be set 4 and 8 ARFCN channels higher than TRX0 respectively.
Non-multiplexed - ARFCN for each channel can be set within the limitations of the RF device. This will vary depending on the particular RF product.
