Dear *, Is it possible to syncronize large number of USRPs (e.g. N210) in time and frequency for building an large MIMO array. My imagination would be using an Ethernet switch hubbing all the USRPs and connect to a host PC vial 10Gbps ethernet. All the USRPs share a common 10MHz/1PPS input. The communications between all the USRPs with the host PC is via TCP (I'm not sure if UHD support TCP now) so that there is no packet loss.
We previously build a 2x2 MIMO using USRP2s with two ethernet adapters on host PC, which is quite successful. Bests, Hanwen
