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.
