uhm... right now we're at 19200baud on the first control system... thats 19.2Kbps... I'd rather take the stability of Zigbee at a speed thats already 13 times faster than what we're using now... not to mention to actually use all the bandwidth of 802.11n/g you'll be using most your processor just to do communications...

At the place where I work, we use some MaxStream ZigBee chip modems to link our plant AGVs together, and as of yet the system has proved flawless and the range excellent, in the 250' x 250' steel-constructed factory they can still communicate with eachother at extremely low (often no) packet drop rates.

Anybody have any other suggestions on radio systems that would be interesting? I know that theres more out there than just Zigbee and the 802.11x standards... any other suggestions?
