The V-Tag Model VT100-6 is a compact active RFID tag that generates its own mesh network and offers features such as:
 
Location Tracking System (LTS)
Temperature
Battery level
Beeper
 
Location Tracking System is accomplished by setting up a fixed tag attached to wall, ceiling, fences and posts around the loca­tion being monitored. Track and monitor your assets without costly infrastructure. The moveable tags then calculate their own positions based on the signals received from the fixed tags and from other neighboring tags.
