Re: 95% can be real if... it determines what 95% coverage is.
Or you could put up another radio. This would create a self-healing mesh, with overlapping coverage. No overload.. It would just roll over to the next available, less busy radio. They have built a system like this in Palm Desert, California. Works VERY well.!
What tehcnology are they using? How big of an area are they covering? Most rural wireless has to have antennas pointed at subscribers and vice versa, to the nondirectional nature of a mesh doesnt make as much sense.
