Keep in mind that multi ARFCN does not require multiple transceivers. You can create different carriers within the bandwidth (sampling rate!) of a SDR. Ralph.

Subject: Re: [Openbts-discuss] Noob Question about multiple ARFCN Hi Alexander, About the multiple arfcns osmotrx support with UHD. So far the only thing I have seen is dual channelling with UmTRX or B210, but there does not seem to be any support of multiples arfcns on a single trx (can't put more than one trx on a B200). Is there a branch of the osmotrx-dev I have not seen ?

Thomas Tsou should be able to comment on how to enable it in OsmoTRX. Please excuse typos.

The transceiver software for that SDR supports multiple ARFCNs using a single physical radio. The transceiver software for UHD based hardware does not yet support multiple ARFCNs. > > Regards, > -Michael > > > On Dec 18, 2014, at 10:37 AM, Arthur Rabaté <art...@gm...> wrote: > > > > Hi, > > > > I am wondering why we can't have multiple ARFCN (contiguous or not) with a single TRX. > > OsmoTRX offers a 2 ARFCN configuration but with 2 trx (B210 for example is supported but not B200) > > I do not know how opencell systems works for multiple arfcns but I can only assume that there are multiple trx inside ? > > > > This question may have been answered before; if so, I will have poorly searched. > > > > Thanks ! > > ------------------------------------------------------------------------------ > > Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server > > from Actuate!
