Real Time Locating Systems are fully automated systems that continually monitor the locations of assets and personnel and it utilizes battery-operated radio tags and a cellular locating system to detect the presence and location of the tags. The Systems are usually deployed as a matrix of locating devices that are installed at a spacing of anywhere from 50 to 1000 feet and they determine the locations of the radio tags. The Systems continually update the database with current tag locations as frequently as every several seconds or as infrequently as every few hours for items that seldom moves and can track thousands of tags simultaneously and the average tag battery life can be five or more years. The Real Time Locating Systems have the feature that frequency of tag location updates may have implications for the number of tags that can be deployed and the battery life of the tag.
