3Why Deploy Wireless Bridging?
4Why Deploy WLAN Bridging?
- Cost
- 3Com Outdoor WLAN bridges are inexpensive,
unlicensed, and do not involve any reoccurring
charges. - Choices are typically Telco circuits or Fiber.
- Telco circuits incur a setup cost and a monthly
cost. - A single T1/E1 charge can range anywhere from
about 500/month up to 1,500/month depending on
region, number of lines and features. - Fiber installation can be very costly. Fiber
interfaces can be expensive, but other costs
include the fiber cable itself, trenching,
conduits, laying and cutting the cable,
connectorization, and right of way permits. A
recent customer chose 3Coms WLAN bridges instead
of fiber because it was going to cost nearly
40,000 to link 2 buildings approximately ½ mile
apart.
5Why Deploy WLAN Bridging?
- Time
- A 3Com Outdoor WLAN bridge link can usually be
setup and working within a couple of hours. - Telco circuits requires scheduling with the local
carrier, and coordination of effort during setup
and ongoing maintenance. - Fiber installations usually needs to be cleared
by the local utilities first since trenching is
involved. The city or county might need to be
involved for right of way issues if the cabling
will be placed across land that is not owned by
the customer. - There are myriad issues that come up during
installation of fiber that require additional
troubleshooting and time.
6Why Deploy WLAN Bridging?
- Speed
- 3Com Outdoor WLAN bridges can create links up to
108Mbps with throughput up to 40Mbps.
Throughput is variable and dependent on such
issues as distance, antenna type / gain,
beam-width, local EMI and physical signal
interference. - A T1/E1 circuit has a maximum capacity of 1.5 to
2.0Mbps. The only way to get more bandwidth is
to buy more circuits at an additional monthly
charge, replace those circuits with higher
capacity and higher cost circuits, or employ
expensive compression devices with a noticeable
but limited bandwidth improvement.
7Why Deploy WLAN Bridging?
- Security
- 3Com Outdoor WLAN bridges offers a variety of
security options the strongest of which is WPA2
with AES, but also support WPA/TKIP, 802.1X,
Local RADIUS MAC authentication, and 64.128.152
bit WEP - 3Com WLAN Building to Building Bridges use WDS
(Wireless Distribution System) as the bridging
protocol rather than Client Bridging. This makes
it more difficult for clients to try to connect
to bridge traffic
8Why Deploy WLAN Bridging?
- Flexibility
- 3Com Outdoor WLAN bridges can be located anywhere
wireless coverage is required. Durable
weatherproof housings with internal lightning
protection assure reliable operation year round. - Access point bridging functionality can be
combined on the same unit, allowing units to be
located throughout parks, campus environments,
shopping malls, etc., with a wireless backhaul
link providing access to the wired data network. - 3Com Outdoor WLAN bridges come as a complete kit
which includes both a wall mounting bracket and a
pole mounting bracket, providing for a wide
variety of mounting possibilities.
