[Openbts-umts-discuss] OpenBTS GSM and UMTS simultaneous operation

[Yile Ku <sti...@gm...>]

We want to build a GSM and UMTS basestation.  We want to run at European
frequencies for both GSM and UMTS for testing reasons.  We are going to run
GSM at the 900 Mhz frequencies, but we are trying to figure out what we
should run UMTS at.   The UMTS bands are 900 and 2100 Mhz.  Can we run both
GSM and UMTS in the 900 Mhz bands simultaneously, or do we need to separate
them and run GSM at 900 and UMTS at 2100 if we want to run them
simultaneously?

Thanks,
Y-
