I am using USRP N210 and XCVR2450.

, it should print 'B' and doesn't send when machine A is sending.
In reality, machine B lost a lot of messages from A, which are supposed to
be received with carrier_sensed().

I found the size is not used anywhere in tunnel.py source file. Does it

I am using USRP N210 and the daughter boards are XCVR2450. Does each
antenna can both transmit and receive, or one antenna can only transmit and
another can only receive?

fixed_delay as 0.01 to 0.1 and test the result.
And also, please set the CSMA threshold carefully to avoid
possible collision.

But when I tested tunnel.py, the working freq is only 2.50 G and 2.51G. Why
doesn't tunnel.py work on the same frequencies as benchmark_tx/benchmark_rx?

*Actual frequency: 4500.000 MHz*
Clearly the 4500MHz is not the real TX frequency. What is that?
