[Chapter-delegates] Internet Pioneer urges Pacific Islanders to face Internet Challenges at PacINET 2008

[Chris Grundemann]

There are a number of options when it comes to terrestrial wireless.  One
example is right here in my home town of Denver, Colorado.  There is a large
microwave radio on a rooftop in downtown Denver which fires at a blank
billboard on the side of a mountain along the I-70 valley.  This billboard
in turn reflects the signal down into the town of Idaho Springs where it has
been the sole source of telecommunications connectivity for many years.  To
answer the question more generally; no, it does not always need to be line
of site.  There are various ways to take advantage of the various properties
of reflection, refraction and diffraction.  If mountains are the problem you
could build a (or several) solar powered active relay station(s) to connect
communities on both sides (never rule out multiple hops - there is a lot
that can be done there).  If it is simply long expanses of ocean (or
desert), there are frequencies which will follow the curvature of the earth,
etc...

I assume that this has been researched in some detail but there may be
possibilities that have been overlooked, it may be worth revisiting.
Especially when the alternatives are as expensive as they appear to be.
