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

[Matt E. <ma...@et...>]

German,

The B200 is a solid low cost way to run GSM.  It also runs UMTS with
OpenBTS and there are 3 LTE packages which run on it.  It has the advantage
of being able to select arbitrary sample rates, so it can work efficiently
with GSM, UMTS, and LTE without hardware changes, resamplers, etc.

The frequency accuracy is fine for all 3, and we have many many
basestations out there running without a GPSDO.  You can also add a GPSDO
if you like, and still be at only $1300.  Plus, it is a real GPSDO with
proper holdover specs and the like.
