I understand from some reports that for the 802.11b (11mbps), the data rate can only reach the most 4.5 - 5.5 mbps. It will never reach 11mbps. Is that true?
If that's true, how is the data rates for cisco aps?
How about the 11a standard? What is the "actual" data speed like?
11Mbps is the max *signalling * rate for 802.11b. With the right packet size (and a strong signal) the good devices, Cisco included, will achieve about 6Mbps (the best test is an FTP file transfer).
At the lower signalling rates (1, 2 & 5.5Mbps) you should also get about 66% of that for data throughput. It's a little different because 1 & 2Mbps use a different coding, but that's close.
Actual throughput for 802.11a is about 22Mbps, with around 35Mbps for the proprietary 'turbo' modes.
