Up Hill and Down Dale
Members of the ISP-Wireless list discuss dealing with wooded hills.
How expensive is a good solution, and can it be made profitable?
[December 22, 2000]
On the ISP-Wireless list in December, DG
asked,
"Has anyone who lives in a wooded hilly region been able
to set up wireless? What's the best way to punch through trees?"
A number of respondents advised DG
to go hiking:
[JU warned] "At the power levels that
we are allowed on 2.4 GHz, the signal cannot reliably 'punch through'
trees and go more than a few blocks. You've got to raise the antenna above
the tree tops. My suggestion would be to set up your access point on the
highest hilltop nearby.
Then, to deliver reliable service, install your customer antennas so
there are no trees between each antenna and the hilltop. With careful
choice of antenna locations and heights, you stand a good chance."
[MKS noted] "If the surrounding hills
are within four miles or so, it looks like most people would have good
line of sight either from their roof tops or from short (20' or so) masts
on their houses."
[JS agreed] "Get on one of those hills
that surrounds your town. You will not be able to service everyone, but
you will be able to service many. Remember, though: the farther away from
the antenna you get, the more important the trees and other obstacles
become."
KM advised checking out the value proposition
before committing to anything complex:
"Anything is possible, but whether it's worth trying depends entirely
on how much value you create from succeeding. In other words, will the
customers pay for the additional trouble and expense the trees will create?
Such as the cost to install guy-wired poles on their roofs, or setting
up many access points and backhaul routes, or installing equipment on
the trees themselves."
JP argued that a little creative financing
can justify an installation like this:
"Our area is covered with trees, but we have stuff on the hills looking
down into town from three locations, and we can service almost everyone
in town. With one well-chosen hilltop, you could pick up enough customers
to pay for a second hilltop easy enough. I've rented hilltop space for
$100-200 a month, traded for services, done all sorts of stuff. Land doesn't
depreciate."
