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.
