Wi-Fi Here, Wi-Fi There
A new chip from Broadcom could make Wi-Fi ubiquitous. (PC Magazine)First your company launched a wireless network. Then you set one up in your home. Whats next? How about having Wi-Fi in your cell phone, MP3 player, or even your digital camera? If chipmaker Broadcom Corp. has its way, the Wi-Fi juggernaut will keep rolling along. The company recently took the wraps off its tiny, low-power Wi-Fi chip called the AirForce One, a technology that promises to put built-in wireless networking into all sorts of electronics gear.
The AirForce One is the first Wi-Fi solution to combine a 2.4-GHz radio, power amplifier, 802.11b baseband processor, and medium-access controller on a single CMOS chip thats smaller than a postage stamp. By putting more than 100 components on a single chip, Broadcom claims the AirForce One requires 70 percent less transmit power, 80 percent less receive power, and 97 percent less standby power than a typical Intel Centrino Wi-Fi solution.
