[srsran-users] SDR for 5G NSA

[Andre Puschmann]

Liam,

for 5G NSA to work with srsRAN, both the UE and the eNB, require a SDR 
with two independable tunable RF chains. See [1] for details on it.

This requirement stems from the fact that band combinations for NSA for 
commercial handsets are very restrictive. We couldn't find a combo that 
fits in the analog bandwidth of a dual-channel SDR with a combined LO 
for both chains, like the B210. If you can, it might be possible to use 
that for NSA with COTS phones.

Thanks
Andre
