Mobile and Handheld Devices to Get Extended Battery Life

By Susan J. Campbell
For all consumers frustrated with the lack of sufficient operating time for battery-operated mobile wireless devices, technologies are becoming available and certified to reduce power consumption and make mobile devices more power efficient. The Wi-Fi Alliance (WFA) has recently certified the 802.11a/b/g dual-band, multimode WorldRadio™ solution from Conexant Systems, Inc. under the Alliance’s new Wi-Fi CERTIFIED™ for Wi-Fi Multimedia (WMM™) Power Save certification program.

Conexant’s PowerSave power management technology is included in the WorldRadio which significantly reduces power consumption. Combining this technology with the WMM Power Save could help drive the increase in adoption of Wi-Fi-enabled mobile devices. Additionally, validation of future products will be measured against Conexant’s chips.

Chee Kwan, vice president and general manager of Conexant’s Wireless Networking business views the certification as a way to increase consumer confidence in Conexant’s products. The WMM Power Save techniques add significant power consumption improvement and conform to industry interoperability and performance standards, assuring customers that their Wi-Fi CERTIFIED products will not only work seamlessly, but also for longer than earlier products.
With the increased demand on wireless devices, the industry has also seen an increase in the demand for extended battery-life. Consumers want the flexibility and freedom of not being tethered to an Ethernet plug in the wall, but the wireless advantage is only as good as the battery operating time provided. WMM Power Save extends the battery life of Wi-Fi devices, such as multimedia cellular phones, enterprise handsets, PDAs and digital cameras, by increasing the efficiency and flexibility of the data being transmitted. To be able to take advantage of the WMM Power Save functionality, both the Wi-Fi client and the access point must be Wi-Fi CERTIFIED for WMM Power Save.
Conexant is a semiconductor company headquartered in Newport Beach, California. With approximately 2,400 employees worldwide, the company boasts that it has enabled more Internet connections through its modem technologies capabilities than all of its competitors combined. Key products for Conexant include client-side xDSL and cable modem solutions, home network processors, broadcast video encoders and decoders, digital set-top box components and system solutions.
The WiFi Alliance consists of more than 200 member companies around the world focused on promoting the growth of wireless Local Area Networks (WLANs). As a non-profit association, the Alliance aims at enhancing the user experience for mobile wireless devices. The interoperability of WLAN products is tested and certified by the Alliance based on the IEEE 802.11 specification. More than 2,000 products have been designated as Wi-Fi CERTIFIED™ since the program’s inception in March of 2000.
The emerging advances in Wi-Fi technology that make it easier for consumers to operate in a wireless environment are exciting for any user. Technology has given us the ability to work anytime and anywhere as long as we have the necessary power to do so. With companies like Conexant on the forefront for setting standards to optimize operating time on battery-operated mobile devices, the freedom and flexibility that technology can offer just became broader.
