Gartner recently restated their recommendations for wireless deployment:

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 .
