Re: [Discuss-gnuradio] How to see what kind of mac/phy schemes?

[George Nychis]

There is currently no MAC layer support.  There has been some work in 
supporting it through the new m-blocks, but I still believe there are 
pieces missing for tightly timed CSMA MACs.  The timestamps are great 
for TDMA, but CSMA is still kind of left in the dark.

I'm working on it as research right now.  I've implemented a CSMA and 
TDMA MAC, but they're currently not available.  Hopefully I can wrap 
them up by the end of August and release them.
