The accuracy and reliability of tracking and locating is increased by using a unique combination of at least two locating technologies. This may be done while reducing the costs for achieving a given level of accuracy and reliability, leveraging existing standard technologies, delivering room level location accuracy, providing choke point capabilities, providing RTLS capability minimizing additional infrastructure costs and maintenance costs, and/or increasing battery life of tags. Information for locating a tag within a region, the region including a plurality of zone or boundary identifier transmitters and a plurality of access points may be combined by (a) receiving by the tag, from one of the zone or boundary identifier transmitters, a zone or boundary identifier, (b) transmitting by the tag, information identifying the zone or boundary identifier and a tag identifier associated with the tag, over at least two channels, (c) receiving, by at least two of the access points, the information identifying the zone or boundary identifier and a tag identifier associated with the tag, transmitted by the tag, (d) transmitting, by each of the at least two access points, the information identifying the zone or boundary identifier and a tag identifier associated with the tag, as well as secondary information for use in deriving a location of the tag, and (e) storing the zone or boundary identifier and the tag identifier associated with the tag, and the secondary information, in association with one another.
