We have done extensive testing with two radios in the same board, set to channels 1 and 11. If you try to transmit continuously on radio 1, radio 2 will act like its channel is busy and wait until radio 1 stops transmitting. All data will stop on radio 2 until radio 1 has finished.
We tested with R52Hn, R2n, and ubiquiti XR2. Same results.
There are no CPU resource issues. Our testing never resulted in more than 15% cpu busy.
You will only see this if you contrive a test (or your application requires) radio 1 to transmit continuously. This is unusual, so most users set their
radios to channels 1 and 11 and it appears to work fine. However, what's really happening is that the two radios are, to some extent, sharing the available bandwidth in the transmit direction.
