The Cisco Aironet® 1400 Series Wireless Bridge creates a new benchmark for wireless bridging by providing a high-performance and feature-rich solution for connecting multiple LANs in a metro area. Building a metropolitan area wireless infrastructure with the Cisco Aironet 1400 Series Wireless Bridge provides deployment personnel with a flexible, easy to use solution that meets the security requirements of wide area networking professionals. Designed to be a cost-effective alternative to leased lines, it is engineered specifically for harsh outdoor environments, yet also works well in indoor deployments. The Cisco Aironet 1400 Series Wireless Bridge is the premier high-speed, high-performance outdoor bridging solution for line-of-sight applications, providing features such as:
The Cisco Aironet 1400 Series Wireless Bridge can be used to provide either:
Ideal applications include:
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.
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.
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
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).
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).
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:
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. Convenient LEDs and an externally accessible Received Signal Strength Indicator (RSSI) for alignment feedback/diagnostics and a quick-hang mounting bracket allows for an easy installation process.
To simplify ordering and installation, the Cisco Aironet 1400 Series Wireless Bridge provides the professional or IT installer with all of the components and accessories necessary to complete most deployments, including:
The CiscoWorks Wireless LAN Solution Engine (WLSE) is available as a management tool for Cisco Aironet access points operating autonomously (without a Wireless LAN Controller) and wireless bridges. CiscoWorks WLSE is a turnkey, scalable, and centralized management platform with an HTML-based interface. It uses Simple Network Management Protocol (SNMP) and Secure Shell (SSH)/Secure Sockets Layer (SSL) for managing Cisco Aironet access points and wireless bridges via a Web browser.
