802.11g Handheld WiFi Module Announced
Agere Systems today announced a new small-form-factor 802.11g mobile Wi-Fi module specifically designed for handhelds. This embedded system-in-package delivers 54 megabit-per-second (Mbit/s) speeds while balancing exceptional range and power savings.
Powered by Agere's complete WaveLAN chip set and software drivers, this module is being developed by Universal Scientific Industrial Co. Ltd. (USI), the leading global design and manufacturing service company, to provide excellent connectivity performance in small-form-factor Wi-Fi devices. Measuring only 20x29 millimeters, the SiP module is a standard product tailored to the size, power, operating distance and performance needs of handheld devices for wireless connectivity in homes, businesses and public hotspots.
The mini-module delivers an extended range of up to 100 meters at 6 Mbits/s. Mobile devices incorporating this solution can take advantage of this range-at-speed performance to provide users with the best possible wireless connection over distance. Using Agere's WaveLAN chip set -- which includes an RF transceiver, media access controller, baseband processor and power amplifier -- the SiP module delivers output power of 14 dBm at 54 Mbits/s operation and 16 dBm at 12 Mbits/s.
This module offers a new "deep sleep connected" mode that enables a device to idle at low operating power while retaining an active association to its access point. This standby power mode - the state most often in use by wireless devices - operates at 1.5 milliamps for the entire module, representing the industry benchmark achieved for low power consumption in 802.11b and g solutions.
In addition, the module is compliant with the draft IEEE 802.11e specification to meet the quality-of-service requirements for applications including voice over wireless LAN and streaming media. The solution will also support the new 802.11i security standard, which is expected to be finalized in June. The mini-module is currently sampling to customers, and is expected to begin volume production in third calendar quarter 2004.
Industry analyst firm Gartner Dataquest estimates that by 2006, 60 percent of PDAs and 5 percent of cellular handsets being shipped will include built-in wireless LAN connections. This module will be on display at the Computex 2004 trade show, being held June 1-5 in Taipei, Taiwan.
