A little
over two years ago, Meadowcreek Computer Works installed a wireless
system on
Black
Mountain to
provide high-speed internet services to the community. The system was based on the
802.11b wi-fi standard which operates at 2.4 GHz. The system started to reach
its maximum capacity after 120 residents and businesses, and
Meadowcreek began to research ways to upgrade the wireless system to
keep pace with the growth.
After looking at various technologies and wireless
systems, Meadowcreek decided to use the Motorola Canopy wireless
system. This system is
a very robust, secure, and
well-developed system. It is used in many parts of
the country where stability and security are needed in a wide area
network environment.
The canopy system that was decided on operates at 900 MHz and
5.7 GHz, which does not conflict with the existing 2.4 GHz wi-fi
system. The Canopy
system also uses a proprietary synching algorithm (taken from GPS
readings from a GPS receiver on the tower) in order to prevent
communication problems which plague wi-fi technology.
In addition to adding four more
access points on Black mountain (two 900 MHz access points and two
5.7 GHz access points), Meadowcreek made a deal with US Customs to
locate 6 access points on Dawson Ridge (two 900 MHz access points,
two 5.7 GHz access points, and two 2.4 GHz wi-fi access
points). A radio
backhaul connects Black mountain with the
Dawson tower
and effectively doubles the capacity of one tower alone.
The new access points on
Black
Mountain and
Dawson will
allow 800 to 1600 more clients to be added to the current wireless
network serving the county.
The 900 MHz access points can reach up to 30 miles, while the
5.7 GHz access points can reach 10 miles with a greater amount of
bandwidth as compared to the 900 MHz access points. The wireless network extends
from south of
Naples to Porthill and
from the west side of the valley to the
Montana
border. If a person can
see the
Black
Mountain tower or Dawson Ridge
tower, that person is able to receive the wireless signal from
Meadowcreek. Although
the system is limited somewhat by needing a line of sight (or near
line of site with the 900 MHz Canopy gear) to the tower, the
subscriber modules can be placed up to 300 feet away from the
customer's home. This
aids in obtaining a signal in the case of a small hill or other
obstruction blocking the line of sight from a home to the
tower.
In the past, a T1 line was used to
support the bandwidth needs of the wireless system. As the wireless network
began to grow, the 1.5Mbps bandwidth of the T1 line became too
limited to service the needs of all the customers on the
network. The Canopy
network has a main backhaul beamed wirelessly from
Spokane. This backhaul has a
capability of 10Mbps (approximately 8 times more than a single T1),
and it is upgradeable to 45Mbps.
The greater
bandwidth capability serves many purposes. It allows businesses to
connect from Bonners Ferry to branch offices in Sandpoint,
Coeur d'Alene,
Spokane, and other surrounding
areas through the wireless network through virtual private
connections (VPNs).
This can be done at a significant cost savings over a
dedicated Verizon line for the same amount of bandwidth. The new system has a low
latency, which allows the use of voice over IP (VoIP)
technologies. Companies
such as Vonage, Packet 8, and other VoIP providers can sell their
services to customers on the wireless network.
The main
portion of the upgrade process took place over the winter, which
increased the time frame for having the system completely ready for
use. However, even with
the small interruptions in service which occur from time to time
while equipment and firmware upgrades take place, the upgrade
process is coming along smoothly. Future plans include
expansion to Eastport, access points to cover new subdivisions not
currently accessible from the current towers, and a redundant
backhaul to
Spokane. It is Meadowcreek's goal to
increase the reliability, stability, and usefulness of the existing
network to 99.999% uptime.
Small changes are taking place daily to turn this goal into a
reality.
