Our lab is using USRP N310's with an external frequency synth ($500), a TI dev board splitting chip ($200?) and an external 10 MHz selenium clock ($2k). The set up is very very good but extremely expensive as well.

After paying for RF cables and a host server, we are roughly getting 1 channel per $4k.

For MIMO and beam-forming, it might be cost effective for you to buy more N210's in order to use the hardware you already have.

A wireless research lab on campus uses lots of B-series USRP's because they are a (relatively) cheep way to set up lots of AP's and clients. That lab has a good 20-30 B-series devices and used them for a wide variety of experiments. Not sure if they are suitable for your desired experiments.

Alternatively, this non-Ettus device may be worth looking into:


I would like to warn you that RF cables (SMA. BNC, N-connector) are surprisingly expensive (and effected by the American tariffs). You should budget accordingly.

Hi dear community members!

I want to run experiments using MIMO and/or beamforming techniques with open source. However, I am getting stuck with hardware. Traditionally, I used USRPs N210 for experiments. I have only two.

Is there any cheap hardware that can support MIMO & beamforming applications on the market?
