I normally resist talking about our own products on this list, but since
there is some incomplete information I will offer some corrections. I
won't speak to competitor's products.
- Get USRP N (not USRP 2), if you want to have access
to variety of
daughter boards, available for USRPs. Though it's quite expensive,
especially if you add a GPSDO to it.
These are the highest dynamic range and will have the best RF performance.
- Get USRP B200, if you want a small single-channel
device. Though
you _may_ have issue if you start playing with handover, as it doesn't
have GPS or a stable enough reference clock.
A GPSDO is available for B200, or you can use the 10 MHz input from an
external source. The B200 is by far the lowest cost option, and it has a
high dynamic range in comparison to Lime-based solutions. If you want
diversity receive and dual transmit, you can get the B210 which is also a
low cost option.
