Subject: [manet] Channel planning for multi-channel MANET

Hi everyone,

The channel spacing is important in planning the
spectrum allocation in multi-channel MANET. In IEEE
802.11, the channel spacing has to be at least 30 MHz
wide in order for two channels to simultaneously
operate in the same geographical area with negligible
interference. 

That standard was made in 1999. I guess
the channel spacing could be much smaller since the
progress in DSP would allow for much more accurate
filtering. 

Does anyone know how small the channel spacing could
be under current technologies?

Thanks!

- Leon
