[MLB-WIRELESS] building a mesh

[Ryan Abbenhuys]

...also, this is why wireless ISP's using current wireless technologies can
never succeed on a large scale. (i'm surprised they've lasted as long as
they have)

You'd be struggling to get more than 15-20 users on a single AP while still
providing broadband type speeds.

They'd also struggle to put in more AP's due to channel overlapping as they
are also limited to 3 or 4 channels at a stretch.
