Non line of sight has interesting possibilities.
Normally wireless needs line of sight access. This means nothing can be
between the two antennas. Any tall trees in the area, you need an antenna
higher.
"Non line of sight" systems typically don't really get around that, what they
do is make each user also a repeater station, so that if you don't have line
of sight to the base, you will have it to someone who does, or to someone
who has it to someone . . .
Of course, this does mean the effective bandwidth for any given person is
less than the total, as traffic is being repeated.
There was a company developing this on Long Island, and has some successful
installs. However, the geography of the NY area is problematic with hills,
valleys, rocks, trees, etc. LI is relatively flat, but the experience didn't
make use around here look promising.
