Low-power chips bring WiFi to remote sensors

摘要

A CALIFORNIAN COMPANY claims to have overcome the power consumption problems that have so far prevented WiFi from being used to sather data from battery-powered sensors. Sunnyvale-based GainSpan - which was formed in 2006 as a spin-off from the chip-maker, Intel - claims that its technology will allow WiFi transmitters to operate for up to ten years, powered by a single AA battery.
