BRIGHT FUTURE FUR ULTRA LOW POWER RF

摘要

Even though the chips ship in their tens of millions each week, the market for short-range, low-power RF technologies operating in the globally popular 2.4GHZ ISM band - such as Wi-Fi, Bluetooth, ZigBee and a slew of proprietary solutions - is far from maturity. In the next few years, many impressive developments will emerge and wireless connectivity will pervade every aspect of our lives. In particular, ultra low power (ULP) wireless applications - using tiny RF transceivers powered by coin cell batteries, waking up to send rapid "bursts" of data and then returning to nanoamp "sleep" states - are set to increase dramatically.
