Aironet 350 Series Wireless Bridge
|
|
|
The Cisco Aironet 350 Series Wireless Bridge enables
high-speed long-range outdoor links between buildings
and is ideal for installations subject to plenum
rating and harsh environments. It is designed
to meet the requirements of even the most challenging
applications, with features including:
- A metal case for durability and plenum rating
and an extended operating temperature rating
for harsh environments
- High-speed (11-Mbps), high-power (100-mW)
radios, delivering building-to-building links
of up to 25 miles (40.2 km)
- Supports both point-to-point and point-to-multipoint
configurations
- Broad range of supported antennas
- Simplified installation, improved performance,
and upgradeable firmware, ensuring investment
protection

Fixed Wireless
Solution |

Designed to
connect two or more networks (typically
located in different buildings), the
Cisco Aironet 350 Series Wireless Bridge
delivers high data rates and superior
throughput for data-intensive, line-of-sight
applications. The bridges connect hard-to-wire
sites, noncontiguous floors, satellite
offices, school or corporate campus
settings, temporary networks, and warehouses.
They can be configured for point-to-point
or point-to-multipoint applications
(see Figures 1 and 2) and allow multiple
sites to share a single, high-speed
connection to the Internet. For functional
flexibility, the wireless bridge may
also be configured as an access point.
The high-speed links between the wireless
bridges deliver throughput several times
faster than E1/T1 lines for a fraction
of the cost- eliminating the need for
expensive leased lines or difficult-to-install
fiber-optic cable. Because bridges have
no recurring charges, savings on leased-line
services quickly pay for the initial
hardware investment. Wireless bridges
connect discrete sites into a single
LAN, even when they are separated by
obstacles such as freeways, railroads,
and bodies of water that are practically
insurmountable for copper and fiber-optic
cable. Combining powerful 100-mW radios,
industry-leading receive sensitivity,
installation tools to assist in bridge
placement, delay spread capabilities,
and a broad array of directional and
omnidirectional antennas, Cisco provides
a complete solution for a wide variety
of fixed wireless applications.
A Rugged Design
The Cisco Aironet 350 Series Wireless
Bridge features an extended operating
temperature range of -20° to 55°C,
allowing for placement outdoors in a
NEMA enclosure or in harsh indoor environments
such as warehouses and factories. With
a durable metal case, the Cisco Aironet
350 Series Wireless Bridge is UL 2043
certified, and designed to achieve plenum
rating as defined by various municipal
fire codes. |

Simplified
Installation and Optimized Performance |
|
|
|
The Cisco Aironet
350 Series Wireless Bridge supports
a variety of features designed to simplify
installation and improve performance.
Cisco Aironet 350 Series Wireless Bridges
obtain their operating power over the
Ethernet cable, eliminating the need
to run AC power to what are often remotely
located wireless devices.
To provide flexibility during installation
and configuration, the Cisco Aironet
350 Series Wireless Bridge may be accessed
either over the LAN connection or via
a console port. The frequency agility
option on the Cisco Aironet 350 Series
enables the bridges to select the clearest
transmission channel, avoiding noise
and interference. Frequency agility
simplifies installation and, by intelligently
avoiding interference and selecting
the best transmission channel, maximizes
throughput. |
