Dear Marcus and all,

Many thanks for the advice regarding the Hydra and ORBIT project.

Actually I’m looking for the open-source 802.11 PHY&MAC packages which  
are  
compatible with Recent GNU Radio and USRP N210/X310.

I’ve searched from internet and got some findings listed below:

1. Hydra PHY & MAC from University of Texas at Austin [1]

2. FTW IEEE802.11a/g/p OFDM Frame Encoder [2]

3. UWICORE m-HOP 802.11 MAC for USRP based on the FTW PHY [3]  
[http://www.uwicore.umh.es/mhop-software.html](http://www.uwicore.umh.es/mhop-software.html)  
\*\*\* All (1-3) only compatible with gnuradio-3.2.2 which was too many  
years  
ago.

4. WIME IEEE 802.11a/g/p Transceiver for GNU Radio v3.7 [3]  
[gr-ieee802-11 - Distributed Embedded Systems](http://www.ccs-labs.org/software/gr-ieee802-11/)  
\*\*\* This is a most recent package for gnuradio 3.7, but is PHY only. Are  
there any MAC package which compatible with this WIME PHY?

5. ORBIT Project [5]  
\*\*\* This is a huge project which can be studied. Are there any project  
provide both 802.11 MAC & PHY like Hydrd did before?

Best regards,  
Jiayi

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:  
[GitHub - bastibl/gr-ieee802-11: IEEE 802.11 a/g/p Transceiver](https://github.com/bastibl/gr-ieee802-11) has the source code, btw.

Greetings,  
Marcus
