BRIDGING FIXED NETWORKS
The Cisco Aironet 1400 Series Wireless Bridge can be used to provide either:
1. The sole connection
2. The primary connection with an additional technology such as a T1 line providing redundancy, or
3. As a back up solution for additional resiliency in conjunction with other technologies such as fiber optics.
Ideal applications include:
• Local Government-Backbone (backhaul) portion of community-based municipal networks such as public safety networks, or any fixed network location
• Education-Higher education campus building interconnects and K-12 schools within a metropolitan area
• Healthcare-Hospital campuses and physician offices
• Enterprise Campus-Building-to-building links (point-to-point or point-to-multipoint), or any situation where a company needs to expand across an area where right-of-way is not possible
• Service Provider-Backhaul to aggregate multiple lower-speed links into a higher speed link
Figure 1. Point-to-Point and Point-to-Multipoint Applications
Mobile Networks and Wireless Bridges
The concept of mobile networks is significant not only for service providers looking to offer seamless network access, but also for individual organizations such as municipal public safety units. In many instances, the technology exists to create the zones that provide the mobile network, but the challenge lies in bringing the network to these zones. The Cisco Aironet 1400 Series Wireless Bridge provides a cost-effective solution to this application. The wireless bridge can connect to the network that contains the 2.4 GHz access points or bridges that are providing wireless zone coverage, and also provide the backhaul link to the high-speed network (Figure 2). Whether these zones are 802.11 hot spots at cafes and restaurants or bridged 802.11b cells for mobile networks, the Cisco Aironet 1400 Series Wireless Bridge provides a non-interfering and higher speed distribution service.
Figure 2. Public Safety Network Utilizing Wireless Bridges
ROI
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. The Cisco Aironet 1400 Series with its 54 Mbps throughput capability connects discrete sites into a single LAN at speeds much greater than leased lines, even when they are separated by obstacles such as freeways, railroads, or bodies of water that are practically insurmountable using copper or fiber-optic cable.
High Performance
Operating in the unlicensed 5.8 GHz band, the Cisco Aironet 1400 Series Wireless Bridge sets a new standard for performance, combining powerful 250 mW radios, industry-leading receive sensitivity, installation tools to assist in bridge placement, delay spread capabilities, and a choice of integrated or connectorized high gain antennas, Cisco provides a complete solution for a wide variety of fixed wireless applications.
Data rates of 54 Mbps can be enabled for point-to-point links up to 8.5 miles, and for point-to-multipoint links up to 2.75 miles. Aggregate throughput can be obtained in excess of 28 Mbps. Also, by using higher gain antennas or lower data rates, ranges in excess of 20 miles point-to-point can be covered. 1
Security
Cisco Aironet has a proven track record for leading the industry with advanced security features. Building on basic wireless security, support for the Cisco Wireless Security Suite is included with the Cisco Aironet 1400 Series Wireless Bridge (Figure 3), featuring support for IEEE 802.1X mutual authentication and strong encryption with Temporal Key Integrity Protocol (TKIP). Network managers can confidently deploy a wireless bridging solution that provides robust security and protection, with the ease of centralized management through a Remote Authentication Dial-In User Service (RADIUS) server such as Cisco Secure Access Control Server (ACS).

Intelligent Network Services
The Cisco Aironet 1400 Series Wireless Bridge utilizes Cisco IOS ® Software to provide a familiar user interface with common functionality, scalability, and security. Additionally, advanced features such as quality of service (QoS) are included, enabling packet prioritization for voice, video, and data. Trunking up to 24 voice-over-IP (VoIP) circuits and data over point-to-point links is also possible. Bandwidth can be increased between bridged networks through the aggregation of multiple bridges at each site through Fast Ether Channel (FEC), or Port Aggregation Protocol (PAg-P), or through routing protocols. For a multipurpose network, Virtual Local Area Networks (VLANs) can be configured by allowing different non-root bridges operating on the same root bridge to trunk different VLANS. Network services can now be segmented based upon end user requirements (Figure 4).
Figure 4. VLAN Configuration for Wireless Bridges
Flexible
Rapid deployment and redeployment can be achieved with no reliance upon telecommunications providers nor a lengthy license or trenching process. The Cisco Aironet 1400 Series Wireless Bridge allows placement in an outdoor environment without the use of an expensive additional National Electrical Manufacturers Association (NEMA) enclosure. Further flexibility is achieved by enabling point-to-point or point-to-multipoint networks with a single product line. The mounting bracket has been designed to allow installation on poles, walls, and roofs, while also providing a mechanism for choosing the desired polarization. The Cisco Aironet 1400 Series Wireless Bridge offers an outdoor wireless bridging solution in two product SKUs. The captured antenna version features an integrated radio and high-gain integrated antenna for user installations of point-to-point links and the non-root nodes of point-to-multipoint networks. The connectorized version provides professional installers with an N-Type connector that allows the deployment of the root nodes of point-to-multipoint networks with omni-directional or sector antennas, or of high gain dish antennas for longer links. The external antenna options are:
• 9.0 dBi vertically polarized omni antenna
• 9.5 dBi sector antenna with support for vertical or horizontal linear polarization
• 28.0 dBi dish antenna with support for vertical or horizontal linear polarization
Ease of Use
Based upon IEEE 802.11a technology and utilizing the same Cisco IOS Software as in a wired network, the Cisco Aironet 1400 Series provides a user with a familiar experience that supports an "out-of-the-box" deployment.
