um, yeah, it's a strict
Hi Bastian,
Thanks for reply. I know they are two different values. 5M is for
the physical layer and 115K bits/s is for the application layer. The
application layer's upper bound should be the physical layer. So the value
of application layer should always be less than the physical layer' s.

Then how to explain the relationship between the 5M and the 115K bits/s
throughput?
I cannot since I see absolutely no relationship. Maybe you want to
explain (in detail) why you think these numbers should match.

Hi ,
I made a mistake. The unit of the throughput is wrong. It should be Kb/s.
And I wrote a TCP client and server to run over the gr-ieee802-11. I set
the sample rate to 5M so that no O errors and the packet lost rate is only
3%. Also I choose the BPSK1/2 encoding. The throughput is only 115K

However, theoretically, as my current sample rate is 10M and BPSK. So the
coding rate should be 10M/2 = 5M b/s. The throughtput

I just found I can't use the iwconfig tap0 rate 20M to setup the bandwidth

But in their video , it can be set in this way. May I know how
