Additionally, Spanning Tree Protocol (STP) support prevents loops from being formed on the network. For more information on these items, see the Wireless LAN Access Points User Guide.

For WDS and STP configuration instructions, see “WDS/STP Settings” on page 45.

MANAGEABILITY

3Com offers a wide range of standards-based management support, from SNMP to 3Com Network Supervisor and HP OpenView for seamless integration with your wired network.

Wireless Infrastructure Device Manager and Wireless LAN Device Discovery tools let you configure parameters, run diagnostics, backup and restore configurations, and monitor performance from anywhere on the network using an embedded web server browser. You can also update wireless device software on multiple devices using 3Com Network Supervisor to simplify bulk updates.

With Power over Ethernet (PoE) support, the same Category 5 cable that connects your access point to the data network also provides its power. A single cable installation dramatically improves your choice of mounting configurations because you no longer need to consider AC power outlet locations. PoE support makes it easier than ever to overcome installation problems with difficult-to-wire or hard-to-reach locations.

802.11G WIRELESS NETWORK STANDARD

802.11g operates in the 2.4 GHz band at up to 54Mbps, and supports the widest coverage—up to 100 meters (328 feet). However, is subject to a greater risk of radio interference because it operates in the more popular 2.4 GHz band.

Consider 802.11g when you need wider coverage and vendor compatibility and you are:

„Maintaining support for existing 802.11b users and the existing wireless investment while providing for expansion into 802.11g.

„Implementing a complete wireless LAN solution, including bridges, gateways, access points and clients; Wi-Fi certification guarantees compatibility among vendors

„Providing access to hot spots in public spaces such as coffee shops or university cafeterias
