RX and TX simultaneously

[maxlacourchristensen]

Hello,

I am using RPI4B and Asus AC56.

I am curious if it is possible to send and receive packets at the same time without significant increase in dropped packets? I have experienced that if the base station sends packets at the same time as the drone transmits packets, I get a significant increase in dropped packets. Is it possible to use a NIC with more antennas and somehow subdivide the band (20/40 MHz) to allow one antenna to do RX and another to do TX at the same time? I have another RTL8812AU NIC with 2 external antennas.

Do you know if there is anything related to MIMO or OFDM which can help in this matter?

You can setup two different nics (each on separate channel) for tx and rx. You need to configure two instances of wfb-ng or modify python code to use different nics for tx and rx and different frequency channels for them
