VARs could play a big role in convincing businesses to embrace WiFi. To do this, some suggest that resellers adopt the technology themselves. But, according to Foundry Networks product marketing manager Michael Hong, VARs need sufficient know-how and training in providing maintenance and support before they can deploy their own networks. Stephen Dane, director of iPass, believes resellers may find a niche in the small and medium enterprise sector, which is not sufficiently served by large telcos. Security risks related to WiFi may mean more consultancy in case of a complex setup for corporate environments. But the major risk for VARs, Applinet technical director Robert Casula noted, is the fast evolution of wireless technology and standards that could make previous technologies obsolete. This could lead to a costly lift-and-shift upgrade for the solutions they sold.
