Hi all,
I need some help finding the thoeretical data rates for 802.11 a, b, g, n standards. I think I should use the following equation...
C = 2Blog2M
C = data rate in bps, B = channel bandwidth in hz, M = # of voltage levels or # signal elements
For instance I look up the channel bandwidth for 802.11a and find its 16.6Mhz (20Mhz total) and its modulated with BPSK so its # of signal elements is 2. After I put them into the formula above I get...
C = 2(1660000)log22 = 33200000 = 33.2Mb/s
Which is way to high according to http://en.wikipedia.org/wiki/802.11a it should be around 12Mb/s. Anyone have any ideas on what could be the problem? Thanks for reading!
