FULL DUPLEX WIRELESS LINK

Hello,

I was wondering a solution that may give me a low latency and high throughput. So I was googling…
Some solutions like AirFiber and licenced radios uses one radio to RX and another to TX.

So my idea is to put 2 RB921 on each side, combined with a duplexer.
. POP1 POP2
RX: 5.2Ghz ← TX: 5.2Ghz
TX: 5.8Ghz → RX: 5.8Ghz

Is there anyway to get this working?
Even using a RB’s to separate traffic to send RX packets in one port, and TX on another?
