Hi Tom,
Can you please elaborate a little "how can i drive the seperate RF paths as
two TRX units controlled by one osmobts instance?"
i have tried setting the configuration file for osmobts-trx (osmo-bts.cfg)
by adding 'trx 1' section at the end, but i got an error when starting
osmobts. i was not able to find any documentation regarding this setup.
further fairwaves umtrx hardware supports 2 seperate RF paths, does that
mean that i can use fairwaves umtrx hardware with single osmo-trx and single
osmobts instance?
thanks,
Arif
