Wireless LAN Outdoor Bridge Solution
3CRWEASY96A
Outdoor solution for secure long-distance
wireless connections
The 3Com® Wireless LAN Outdoor Bridge Solution is a comprehensive building-to-building outdoor
wireless LAN kit that reduces the need to evaluate, purchase and assemble separate components. One
convenient package includes everything you need to offer an easy-to-manage building-to-building
wireless LAN. The package features a 3Com Wireless LAN Building-to-Building Bridge with integrated
antenna and power-over-Ethernet cable in a durable, weatherproof enclosure.
The bridge uses either of two network topologies:
Point-to-point
I
I
Point-to-multipoint
The first illustration shows the point-to-point topology (also known as Ad Hoc Network Mode). Notice
that the bridges face one another. While this is elementary in a close setting, real-world conditions such
as long distances, mountainous regions, and architectural barriers will not allow for such a precise
alignment. However, those conditions will not necessarily prohibit effective communication
between locations.

If necessary, you can mount an antenna inside a building; however, indoor placement reduces the antenna’s effective range. To ensure the physical safety of anyone near the antenna and to prevent damage to the bridge, follow the building codes for antenna installations in your area.This is another good reason to make sure that only a professional performs the installation.
