Cisco 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:

• High-speed (11-Mbps), high-power (100-mW) radios, delivering building-to-building links of up to 25 miles (40.2 km)
  
  
• A metal case for durability and plenum rating and an extended operating temperature rating for harsh environments
  
  
• 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. Like Cisco Aironet 350 Series Access Points, 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. (See Figures 3 through 5.)

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.

Investment Protection

Cisco will continue to add features, functionality, and enhancements to its bridge firmware. To protect user investment, Cisco Aironet 350 Series Wireless Bridges feature enough storage to handle future firmware upgrades.
