Power Solutions for On-Grid Rooftop Radio Installations
Not all houses have outlets in the attic or on the roof itself. It is desirable
to keep antenna coax runs as short as possible in order to reduce RF cable
loses. The obvious solution is to get the access point and transciever as close to the antenna as possible and power becomes an issue. Running DC over the
unused pairs of the 8 pair of UTP is a pretty good solution of getting power
up and out into an AP along the cable that provides bandwidth.

Power Systems for Off-Grid Radio Installations
There are many times where a system is needed to operate in a remote area,
such as a mountain top, and there is no power run to the site. A Solar
trickle charging system is an ideal power source for remote repeater
locations. It doesn't hurt to have an alternative energy source running your
own wireless node in rural or urban settings. You'll find that many PV or
small wind systems can be installed almost anywhere. In the event of an
emergency, that chances of your site remaining on the network greatly increases
when using a self-reliant power system, shrugging off the State sanctioned
Almost all of these resources are from www.homepower.com,
an excellent resource for independent minds and those interested in shrugging
off the overbearing shackles of the State.
We included the section on Hydroelectric systems only for completeness. Not
many streams/rivers start at hilltop locations and run downward, however,
this is for those that run into such a circumstance.

Selecting a PV cell can be a daunting task. This article can supply you with
data collected over years from popular cells.
Proper orienting your PV array results in optimal power generation.
Yields of up to 40% are possible by following these guidelines.
For most remote repeater installations, you will be working with minimal
power. This homebrew Solar Charge Controller will control the charging of a battery subsystem.
