PERFORMANCE AND RELIABILITY

3Com wireless access point performance features ensure reliable and seamless connections for users wherever they roam. Automatic channel selection automatically finds the least loaded channel for interference-free communication. Auto network connect and dynamic rate shifting keep users connected through a wide variety of conditions by changing to the optimum connection speed as they move through the network.

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.

WIRELESS NETWORK STANDARD

FAR-REACHING 802.11G

802.11g operates in the 2.4 GHz band at up to 54Mbps. Ratified in 2003, it supports the widest coverage—up to 100 meters (328 feet). 802.11g shares the 2.4 GHz band with other popular 802.11b devices that use this unlicensed radio spectrum. Use of other devices in this frequency band can cause interference with 802.11g signals.

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.
