DATA SHEET 3Com 11 Mbps Wireless LAN Building-to-Building Bridge (R) Key Benefits Top Performance Manageability The 3Com 11 Mbps Wireless LAN building-to-building bridge is based on IEEE 802.11b technology to ensure consistent top performance.* The simple-to-use management interface helps you manage all bridges from anywhere on the same subnet on the network, or use Telnet to remotely manage this bridge over the Internet. (R) Flexibility This bridge delivers both point-topoint and point-to-multipoint connections at various ranges, depending on which antenna you choose. Reliability Support for dynamic rate shifting helps keep your network connections constantly available and reliable. Long-range, cost-effective wireless connectivity between sites As part of our wireless LAN family, the 3Com 11 Mbps Wireless LAN building-to-building bridge provides reliable, high-performance connections between your hard-to-wire sites. Extend your network to previously hard-to-reach users without leasing data circuits or having to lay cables. Simply attach a bridge to your existing wired network and another to the new building. Connect multiple buildings, portable or temporary classrooms, and temporary networks. And if your company's network requirements or location change, the wireless building-to-building bridge can be easily relocated. Security Support for 40- and 128-bit WEP encryption keeps network data and transmissions safe from a security breach. Plus, this bridge uses encapsulation techniques to help protect data. get throughput exceeding that of two dedicated T1 lines. Plus, you won't have to worry about expensive leasedline service that's actually slower than this wireless bridge. Flexible Connections With point-to-point and point-tomultipoint connectivity options, the 3Com wireless building-to-building bridge lets you transfer information between two buildings or multiple buildings across campus. What's more, you can choose the antenna option that best fits your needs--get transmissions up to 1300 meters with omni-directional antennas, and 4100 meters using sector panel antennas. High Performance With a wireless 3Com building-tobuilding bridge, you get high-speed, long-range connections. In fact, you'll *Data throughput can vary depending on several factors, including network traffic load, distance between bridges, and antennas used. 3COM(R) 11 MBPS WIRELESS LAN BUILDING-TO-BUILDING BRIDGE Cost Effective Figure 1. Point-to-multipoint connections from one to multiple buildings using omni-directional antennas. Figure 2. Point-to-point connections from one building to another using sector panel antennas. Simple Management The easy-to-use graphical interface reduces management burdens. Manage all of your bridges from anywhere on the same subnet, or do it over the Internet using telnet. Easily align antennas with real-time signal strength reporting and usage data. Plus, default settings make configuration simple--all you have to do is hook them up. Complete Security When you choose the 3Com wireless building-to-building bridge, you don't have to worry about security. Support for both 40- and 128-bit WEP encryption lets users exchange information privately. Plus, our bridge uses a 3Com proprietary protocol to encapsulate data. This protocol ensures the wireless bridge will not interfere with VPN or other protocols--so your encrypted data passes right through. 2 Now you can connect all of those hard-to-wire locations for less. With a 3Com building-to-building bridge, you don't have to worry about running expensive and tough-to-install leased lines or fiber-optic cabling. Just connect your wired LANs to wireless building-to-building bridges, or connect a remote building-to-building bridge to a 3Com 11 Mbps Wireless LAN Access Point 6000 or a 3Com AirConnect Wireless LAN Access Point. In minutes, you've interconnected a remote site with the central site. Best yet, this hardware investment can pay for itself, when compared to the money you would have spent on leased-line service. (R) Customer Support Quick access to support information is available on 3Com's Web site at www.3com.com. When to Buy Our building-to-building bridge is ideal for organizations who: * Are looking for a cost-effective alternative to leased lines. * Don't want to invest in laying expensive and tough-to-install cables since their network requirements or location may change. * Want a simple way to connect remote and hard-to-wire locations-- between office buildings that aren't already connected to one another, portable classrooms and cross-campus office buildings, and buildings separated by other structures such as bridges or freeways. 3COM(R) 11 MBPS WIRELESS LAN BUILDING-TO-BUILDING BRIDGE Networking on a Tight Budget Consider this hypothetical scenario: Jill, the principal of Fairmont High, is excited about the new addition to the school addition--three computer labs, 15 classrooms, and more. But that's two years off. Classrooms are bursting at the seams. More students are on the way. And 50 new computers need to be networked. Is it possible on the school's budget? Yes. Using our building-to-building bridges, she turned one of three new portable classrooms into a computer lab Product Features and gave the others network access-- without running cables. She connected one bridge to the school network and another to a 3Com 11 Mbps Wireless LAN Access Point 6000 in the portable computer lab. Now all of the new computers, including those in portable classrooms, have access to network resources and the Internet. Just like you'd expect--a simply powerful solution from 3Com. Fast data transfer rates Allow bridging speeds much faster than leased-line service. Excellent range with antenna options Provide wireless links up to 1300 meters using omni-directional antennas, and 4100 meters using sector panel antennas. Point-to-point and point-to-multipoint support Lets users transfer information between two buildings or multiple buildings across the campus. Dynamic rate shifting Keeps network connections available and reliable by automatically determining transfer rates based on signal strength and environmental conditions. MAC layer encapsulation Ensures LAN protocols are transparent to the user. Secures data over the wireless link. 40- and 128-bit WEP encryption Allow users to exchange information in full privacy. Transparent to VPN protocols Enables encrypted data to pass without interception. GUI management interface Helps you to manage all bridges from anywhere on the same subnet--also displays signal strength monitoring and usage data. Remote management Allows IT administrators to manage the bridge remotely, using the Internet and Telnet. Firmware upgradeable design Provides convenient local and remote firmware updates from anywhere on the same subnet, reducing IT workload and helping to lower total cost of ownership. Protocol independent Supports all networking protocols, including TCP/IP, IPX, and more. 3 3COM(R) 11 MBPS WIRELESS LAN BUILDING-TO-BUILDING BRIDGE Specifications 802.11b Data Rates Supported Receive Sensitivity Bridging Protocol 11, 5.5, 2, 1 Mbps 11 Mb: -81 dBm 5.5 Mb: -84 dBm 2 Mb: -85 dBm 1 Mb: -87 dBm MAC layer encapsulation Range Transmit and receive information up to 4100 meters between wireless building-to-building bridges, depending on the antenna selected.
