San Francisco, CA - Gartner Symposium/ITxpo.  Last October, Gartner changed its overall recommendation for basic WLAN technology from 802.11b only to 802.11a/g. In a session today, Gartner restated its position on which physical standards should be selected for notebooks and access points. 

Notebooks, which tax networks the most with bandwidth needs, should be moved to 5GHz using 802.11a. 802.11g is not recommended as a sole strategy because it operates in a band (2.4 GHz) that is increasingly crowded due to its backward compatibility with 801.11b, said the Gartner analyst . 

If your orgnization uses Web-enabled handhelds, remember that unlike notebooks, they don't have the bus speeds to support data transfers of 54Mbps, so they must operate at the slower 802.11b and remain at 2.4GHz. They’ll gain more operational bandwidth since these devices will not be sharing with notebooks, Gartner noted. Furthermore, wireless-enabled peripherals such as printers have limited bandwidth requirements, so they too should be running on the slower 802.11b networks.

Gartner recommended reviewing all equipment to ensure it conforms to all legal frequencies with the country of use, and to consider WAN installation within the building at the same time as WLAN deployment. Specific recommendations include purchasing 802.11a/g access points and adapters with WPA or WPA2 support, and planning a future WLAN with 802.11a at the center, not 802.11g.

    I have been an advocate of using 802.11a/g for the last six months or more, but most large organizations (85,00 - 130,00 people) have been paralyzed by the fact that they just got 802.11b working and secure. The investment in the newer technology (so I am told) has made upgrades cost prohibitive. I am surprised to see them just starting to use technology like Bluetooth.

    Where do companies in the USA or other countries stand in their quest to move to 802.11a/g?

    • 802.11b is expected to virtually disappear by 2009

      hjbevil,

      According to Gartner: Most enterprise-class access points will be of dual-band (2.4 gigahertz [GHz]/5GHz) physical standard by the end of 2009, accounting for 92 percent of shipments. Most consumer-class access points will be 802.11g physical standard by 2009 (87 percent of shipments); dual band will account for approximately 10 percent of shipments, and 802.11b is expected to virtually disappear by 2009.
