CHAPTER 1: INTRODUCTION
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 lets you configure parameters, run
diagnostics, backup and restore configurations, and monitor performance from
anywhere on the network using an embedded web server browser.
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 STANDARDS
Understanding the characteristics of the 802.11g and 802.11a standards can help
you make the best choice for your wireless implementation plans.
802.11G
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.
For those organizations demanding even higher speeds, a “turbo mode” feature
can boost throughput rates up to 108 Mbps. 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
