Ettus B200 SDR board (USB3 carries simple I/Q) – you need USB3 on server. Other SDR models may work,
we have not tried them. We found you need to separate the TX/RX antennas by a few meters with coax
extenders for best performance.
Scope – not really required but since you want to ensure low power and proper band it’s helpful. Here is
the 2.5Ghz uplink and 2.6Ghz downlink shown on band 7 with 120Mhz separation. Band 7 block was
graciously loaned to us by Canadian operator Telus. This is licensed spectrum so either you need a Faraday
cage, permission or a test licence.
