The Wi-Fi Alliance now certifies features for Wi-Fi networks that will extend battery life for mobile devices. This extension of the Wi-Fi Multimedia (WMM) program, called Power Save, helps pave the way for rapid proliferation of Wi-Fi technology into phone handsets where battery life is critical.

WMM Power Save gives device manufacturers and developers a robust framework to improve Wi-Fi power efficiency, via improved signaling capabilities and the opportunity to fine-tune power consumption. The certification for both access points and client devices uses mechanisms from the recently ratified IEEE 802.11e standard, and is an enhancement of legacy 802.11 power save.

"As many as 55 million subscribers for Wi-Fi enabled mobile phones are expected in the consumer market alone," said Monica Paolini of Senza Fili Consulting.

The following devices are the first to be Wi-Fi CERTIFIED(TM) for WMM Power Save, and currently populate the program test bed:

  • Atheros AR5002AP-2X Access Point
  • Broadcom AirForce(TM) BCM94704AGR Dual-Band 802.11a/g Access Point
  • Broadcom AirForce(TM) BCM94309CB Dual-Band 802.11a/g PC Card
  • Cisco AIR-AP1231G-A-K9 with AIR-RM21A-A-K9
  • Conexant 802.11a/g PRISM WorldRadio
  • Marvell Semiconductor 802.11a/b/g WLAN router
  • Ralink 802.11a/g Mini PCI
  • Winbond Mini PCI 802.11a/b/g WLAN Client
