Introduction to the Wireless Bridge
The Cisco Aironet 1400 Series Wireless Bridge is a high-performance
outdoor-deployable wireless bridge that provides wireless connectivity
between multiple network locations within a metro area with a low total cost
of ownership. The bridge operates in the unlicensed UNII-3 frequency band
(5725 to 5825 MHz) and provides high-speed data transfer rates of 6 to 54
Mbps.
The bridge is designed for applications requiring high data throughput over
intermediate ranges. For a point-to-point link, the bridge provides a
maximum speed of 54 Mbps at ranges of up to 7.8 mi. (12.5 km) using the
integrated antenna. The system is also configurable for point-to-multipoint
operation over distances of up to 2.0 mi. (3.2 km) using a 9-dBi gain
omnidirectional antenna at the root bridge site and a 22.5-dBi gain antenna at
the non-root bridge site.
In addition, two point-to-point bridge links can be stacked to increase data
throughput or provide aggregation and redundancy.
Two configurations of the bridge are available:
•Integrated (built-in) 22.5-dBi antenna
•External antenna (connects an optional antenna)

Network Configurations
The following sections describe the bridge’s role in three common network
configurations: point-to-point, point-to-multipoint, and port aggregation or
redundancy.
Point-to-Point Configuration
In a point-to-point configuration, two bridges connect two LAN networks
together using a wireless communication link. The following illustration
shows a typical point-to-point configuration.
Point-to-Multipoint Configuration
The point-to-multipoint configuration connects the main LAN network to
multiple remote LAN networks. The following illustration shows a typical
point-to-multipoint configuration.

Port Aggregation or Redundancy Configuration
The port aggregation or redundancy configuration increases bandwidth or
backup redundancy communications between two LANs. Port aggregation
for increased bandwidth occurs when both wireless links simultaneously pass
Ethernet traffic. Backup communication redundancy is achieved when the
second wireless bridge link is used if the first link fails. The maximum
number of bridges allowed for redundancy configurations is two. The
following illustration shows a typical port aggregation or redundancy
configuration.
