Wireless Network Standards

3Com 3CRWE875075A Wireless Network Standards, FAR-REACHING 802.11G, HIGH-PERFORMANCE 802.11A

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.

Understanding the characteristics of the 802.11g and 802.11a standards can help you make the best choice for your wireless implementation plans.

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). 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:

nMaintaining 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

HIGH-PERFORMANCE 802.11A

Ratified in 2002, 802.11a is IEEE’s more recent wireless standard. It operates at the 5 GHz band and supports data rates at up to 54 Mbps. For those organizations demanding even higher speeds, a “turbo mode” feature can boost throughput rates up to 108 Mbps. And because there are fewer devices in the 5 GHz band, there’s less potential for RF interference. However, because it is at an entirely different radio spectrum, it is not compatible with 802.11g.

The higher spectrum provides about 50 meters (164 feet) of coverage—about half what 802.11g offers.

Consider 802.11a when you need high throughput in a confined space and you are:

nRunning high-bandwidth applications like voice, video, or multimedia over a wireless network that can benefit from a fivefold increase in data throughput

nTransferring large files like computer aided design files, preprint publishing documents or graphics files, such as MRI scans for medical applications, that demand additional bandwidth
