The Wi-Fi Alliance on Tuesday is set to attack one of the main problems with wireless LAN phones by certifying features to extend battery life.
The industry group that certifies interoperability of Wi-Fi products is adding a label it calls WMM (Wireless Multimedia) Power Save, which identifies products that have reduced the power needed to use multimedia applications over wireless LANs, said Frank Hanzlik, managing director of the alliance.
Using a wireless LAN for VoIP (voice over Internet Protocol), streaming video, and other multimedia applications increases the power consumption of Wi-Fi, which already tends to drain battery power because of ongoing searches for nearby access points, said IDC analyst Abner Germanow. The size and weight requirements of Wi-Fi phones as well as dual-mode cellular and WLAN handsets, plus the need to carry them around all day, make power consumption even more critical.
Equipment certified for WMM Power Save should extend battery life under multimedia use by between 15 percent and 40 percent, Hanzlik said. On Tuesday, the Wi-Fi Alliance will introduce the certification and also announce the first handful of products that have received the seal, he said. A variety of chip sets, product reference designs, and devices from vendors including Atheros Communications, Broadcom, and Cisco Systems have been certified in the first round, according to the group. There won’t be a WMM Power Save logo on the boxes of certified products, Hanzlik said. Instead, information about each product’s certifications will be available on the Wi-Fi Alliance’s Web page.
