hi,

well today i was thinking about non-ovelapping channels like 1_5_9_13 but
for US or  Canada 12 (low power but OK) ;  Then it hit me!!
* 4 channel layout for US:*

*OFDM* subcarriers use *16.25*mhz / 2 = 8.125 then
2412 -2462 = 50mhz
*tail *e *head*  -16.25mhz  so there is space for two non-overlapped
channels with some guardband
(channel 1 center freq) 2412 + 8.125 =  2420.125
(chan 11 center freq)   2462   - 8.125 =  2453.875           2420.125 -
2453.875 = *-33.75*

2420.125 + 8.125 = *2428.25*  (~ new channel 4 )
2428.25 +  16.25 *+ 1.25mhz guard*  = *2445.75*     (~new channel 8)
2445.75 + 8.128 = 2453.875
2462 - 8.125 = 2453.875


the thing is how to use this in newer N AC...
