[MLB-WIRELESS] building a mesh

[Ryan Abbenhuys]

Unfortunatelly a mesh on current wireless technology has a few problems. 
The main one being that in an actual true mesh the noise floor would be
extremely high.  So you might have a "mesh" network, however it would be
extremely slow.

The only mesh that will truly work is a sectored mesh similar to the way
mobile phone towers work and use separate channels for each sector of
coverage, and separate channels for tower to tower links. Due to the
limitations of current wireless gear you'd be limited to only 3 interfaces
per base station making coverage and linking awkward to organise.

(anyone mobile network guru's please correct me if i'm wrong.)
