Description Gary Pei 2010-10-25 13:32:58 UTC

Created attachment 1005 [details]
Modify GetChannelFrequencyMhz to get the center freqency correctly for 802.11a.

According to 802.11-2007 equation 17-27 on page 613 for 802.11a 5GHz:

Channel center frequency = Channel starting frequency + 5 × nch (MHz) (17-27)

Thus, for example, channel 36 should be 5180 MHz. However, current code return 5175 MHz. Current code is correct for 802.11b/g.

I applied a different (simpler) fix
