1) The sequence numbers are not in accordance with the data. Sometimes
the first packet I get has sequence number 0 but at other times I get
sequence numbers like 5 or 41. The mac frame length is 524. An example
sequence numbers pattern was 5,36,452,753,961. I do not understand why
are the sequence numbers random? The antennas are very close to each
other so shouldn't the packet loss rate be very low? And are packets
corrupted and GNU Radio can not decode them properly?
The unreliability can have multiple reasons, like
- too high gain
- too low gain
- overruns/underrruns
- DC offset (try different LO offsets)
The constellation plot is usually a good indicator how good it works.
Placing the USRPs side by side doesn't always make things better.
2) My transmission does not work for any frequency other than 5.89G. I
can't understand what could be the reason for this. Not even 5.88G. My
daughter board supports 1.2G to 6GHz.
Can you describe a bit more verbose what you did and what happened?
Actually, that should work by just changing the frequency in the GUI.
To debug, it might also be helpful to test your setup with a WiFi card.
This is helpful to understand if the problem is in the sender or the
receiver.
Best,
Bastian
