Re: [Openbts-discuss] Hardware for OpenBTS (GSM/GPRS and UMTS)

[Ralph A. S. d. <ra...@sc...>]

Well, I do not know the NI modeling scheme, looks a bit like a N200/N210, but with broader bandwidth in mind (like needed for LTE), I would recommend a somehow modern USB3 radio like the B200 or B210. For me my B210 has become a real Swiss Army Knife. Gbit Ethernet soon comes to its limits when dealing with 3G/4G/5G, and (only my personal impression) I do not like having Ethernet and UDP for high speed sampling. Sure, USB3 is not really better, but at least it is point to point, and the link speed is higher, allowing more headroom for things that can go bad :)

Hello,

We are going to order new hardware to run OpenBTS in our lab, so far we have been using USRP2.

According to the wiki (http://openbts.org/w/index.php/Ettus_Research_USRP) there several models supported, although i can see that in the build shell script the supported radio types is limited to SDR1, USRP1, B100, B110, B200, B210, N200 and N210.

What about the new USRPs by National Instrument, are they supported? I was considering NI USRP-2932 (http://sine.ni.com/nips/cds/view/p/lang/da/nid/212999).

I would really appreciate any recommendations about the hardware. The main use is for our lab for 2G and 3G (and perhaps also for openLTE), but there is no need for high power or outdoor installations.

Thanks you in advance.
