Faster Wi-Fi Uses Less Power

Researchers at IBM have found a way to use a hybrid transistor to control the flow of current through circuits. By using a technique normally used to make CMOS circuits more efficient, they have increased speeds three times, while using 80 percent less power.

These circuits used in wireless devices, such as Wi-Fi cards or 3G mobile phones would dramatically reduce power consumption and increase battery life. Anyone who has tried a Wi-Fi card in an iPaq knows how much energy these devices currently use.
