[QUOTE="Norval, post: 1000560, member: 62"] Those would be carrier frequencies. The 20Mhz would most probably refer to bandwidth around those carrier frequencies. Based on the Nyquist rate, max symbol rate = 2 x max frequency bandwidth. But we never use the Nyquist rate, as it does not provide safety gaps between filters and would result in interference. The relation between bit rate and symbol rate as I mentioned before depends on the modulation and can range between 1:1 for BPSK and 8 bits per symbol for 256QAM. I doubt very much that anything hight than 64QAM (6 bits per symbol) would be used in Wi-fi though. [/QUOTE]
