10 or 15mhz channels for 2.4 EPMP

Subject says it all. My competitor has hosed the 2.4 spectrum for any chance of a 20mhz channel. So 10 or 15 would be sweet.

5 and 10 MHz channels are already supported.

On my AP, running 2.6.2, TDD mode allows only 20/40mhz. Standard WIFI does support 5,10,20 and 40. But I need TDD mode to use 10mhz...

Whate frame size are you using? 5MHz and 10MHz are not supported in TDD mode with a 2.5ms frame size. However, TDD does support 5MHz and 10MHz as long as the frame space is 5ms.
