A quick question, what is the time reference you are using for the TDMA engine? Is it GPS or something else? How accurate about the time synchronization?

Hey list,
For those who were not at the GR Conference 2012: I presented some work
demonstrating a simple ARQ MAC over TDMA; using GNU Radio and USRPs in
GRC. Its very cool work, I encourage anyone to take a peek at the
slides, and checkout the repo and run the examples.
The MAC layer work is actually the work of John Malsbury (I'm just the
messenger). He will be continually polishing and debugging the code over
the next week or so. There should be a wiki page soon...
So, I promised at the presentation that I would email the slides and the
relevant information to checkout the repository.

*Note*: Users will have to generate the tdma hier block first, and then
reload GRC to use the top level simple MAC block.

Feedback is always welcome!
