[Openbts-discuss] MultiBTS using two USRPs

[Deepika K. <dee...@gm...>]

Hey All,

Can anyone guide me a bit regarding running 2 openBTS simultaneously using
two USRPs on one PC. Actually,I want run two GSM bands i.e 900 and 1800
using two USRPs and two copies of OpenBTS on one computer. I have my first
usrp with IP address 192.168.10.2 and the second one with the IP
192.168.10.3.
Now, when i connect the USRP with IP address  192.168.10.2 , it attaches to
* ANY* of the GSM stack i.e either 900 or 1800 band openBTS randomly . What
i want exactly is to connect the USRP with IP address  192.168.10.2 to
attach only with GSM stack of 900 band openBTS and 192.168.10.3 to GSM
stack of 1800 band openBTS only and specifically.
Is there anyway to implement such an arrangement or do i have to make any
modifications in the codings of both openBTS ?

Any help in this regard will highly be appreciated.
