In
the last few years wireless technology has been developed to the point
that it is reliable enough and inexpensive enough to offer an alternative
method to delivering the last mile necessary for a broadband Internet
connection. There are actually many different solutions that an
ISP can use to offer this service. Even in large cities where DSL
and Cable modem is wireless available wireless solutions are becoming
more popular because they both don't depend on a wired infrastructure
and have proven to be extremely reliable.
In deciding
which wireless technology to use Root Automation decided to use Motorola's
Canopy Wireless solution. This is because of three major
reasons.
First, the
system which Root Automation utilizes has been developed to offer
a outdoor solution. Many other ISP's are currently offering
wireless Internet access using the 2.4Ghz frequency which has two
basic technologies, FHSS & DSSS. Both of which are really
designed for indoor use and have many different potential conflicts
from 2.4Ghz phones, and microwave ovens just to name a few.
Second, the
system which Root Automation utilizes is easy to install. The
subscriber module only weighs 1 pound and can be easily secured
to the side of a building. The Motorola Canopy system also
utilizes a Power-Over-Ethernet connection to both provide power
to the subscriber module and hook into your computer (Just 1 small
cable). Many computer systems already have a Ethernet
card (also commonly called a network card or NIC card). If
your computer doesn't have one they can be easily installed with
either an internal card or a USB to LAN converter.
Third, the
system which Root Automation utilizes follows all of the FCC guidelines
and can be installed by a non-professional. That's
right, this is an issue. Some of the other systems out there
have a coaxial cable which runs from the transmitter/receiver (which
may be a card in your computer, an external box hooked to your
computer through a USB or serial connection) to the antenna. According
to the FCC systems like this are supposed to be professionally
installed which makes sense because RF frequencies are traveling
down the coaxial cable. That is why the Motorola Canopy system
and a few other systems out there have the transmitter, receiver
and antenna build into one FCC licensed box.
