Re: [Discuss-gnuradio] Looking for 802.11 MAC & PHY Package

[Marcus Müller]

Hi Jiayi,

:) gr-ieee802-11 is, as far as I know, the most comprehensive,
functional implementation so far. It *can* talk to consumer cards -- but
of course, that's not because it has a complete MAC implementation.
Actually, doing a really standards-compliant IEEE802.11agp MAC can't
really be done in host software alone -- the gigabit ethernet interface
alone just has too much latency, and you'll have to be really fast when
detecting ACK's, calculating checksums and sending out the reply. I
doubt you can implement a fully working IEEE802.11 MAC in software alone
without touching the FPGA.

Here's the official source code:
https://github.com/bastibl/gr-ieee802-11 has the source code, btw.


Greetings,
Marcus
