I don't know of any wireless product that comes close to it's theoretical rating.
This year, I was running throughput testing for a demo board. At 10-30 feet in a quiet environment (as shown on a spectrum analyzer), we were achieving about 120 Mb/s out of a theoretical 300 Mb/s using IXChariot software.
If all robots are sharing one channel, that is pretty unnerving, especially given the throughput requirements for a single video feed.
