Wireless Proximity Key Fob Doesn't Need a Smartphone

摘要

Ultra low power (ULP) RF specialist Nordic Semiconductor ASA announces that a Norwegian consumer product developer called Unikia has developed a low cost proprietary 2.4GHz wireless key fob that Unikia claims will retail for around US $25-30 and won't require the end user to download an app or employ a smartphone or other computer gadget in order to use. In operation, the user simply purchases a pair of pre-paired key fob-sized tags that can each be used to find the other at the push of a button by sounding an audible alarm in the partner tag (up to a range of 40m).
