We have a few years of experience with the millimeter microwave gear (our
units operate in the 60-70GHz range); the solution was driven by cost and
logistics in order to provide a high-capacity link to a research facility
on a small island (the island is somewhat famous as it appears in the title
shot for Gilligan's Island). The radio path is >2 miles, and supports a
GigE payload. While we've had a couple of problems that required attention
by the vendor, the link has been stable, and is the primary link to that
site. At this high frequency, you'll need to pay attention to stuff like
weather and seriously consider space diverse links depending upon the
nature of the payload. We also have some recent experience with a free
space optics link (>1 mile, also supporting a GigE payload). While the
characteristics are slightly different, environment also requires some
We have heard discussion about higher data rates and longer distances under
development, although these usually are for specific, burst-type purposes
as opposed to carrier-type links.
Feel free to contact me directly if you'd like to pursue further.
