A Texas company has introduced a WiFi sensor tag called Tag4M, which integrates RFID and web based applications to create an "instrumentation cloud". The credit card sized tag searches for and automatically associates with an off-the-shelf 802.11b/g access point. Each Tag4M unit has its own permanent MAC address, and it shares a common SSID (default network name) with the AP so it can transfer data and accept commands from any predetermined web page. Users can also connect the AP to a LAN to operate a Tag4M in Local mode. With low power consumption, the Tag4M's WiFi radio chip and ceramic antenna can operate at a range of 50 m indoors and 100 m outdoors, and last as long as two years.
