Claim 19:
20. A method of position location of a plurality of tags in a system, comprising:
providing a first network with a network operating element coupled to the first network;
providing at least one anchor network gateway coupled to the first network, the at least one anchor network gateway providing an anchor network;
forming a network of a plurality of nodes separate from the network operating element, wherein the plurality of nodes comprises fixed position anchors configured to communicate via ranging with the plurality of tags and directly via the at least one anchor network to the at least one anchor network gateway; and
operating the system using accurate timing provided by the network operating element within networked wireless communication protocols to provide a global location network schedule for the system;
wherein the network operating element comprises: a time source independent of the plurality of nodes and a time division multiple access location network manager (TLNM) configured to operate the system, the time source configured to provide timing information to the TLNM and through the TLNM provide timing information to the plurality of nodes for operation of the system in conjunction with ranging information from the plurality of tags received through the plurality of anchors and the at least one network anchor gateway,
wherein the timing information is passed from the time source to the TLNM and over the communication network to the wireless anchor network gateway and the wireless anchor network gateway passes the timing information on to the anchors over the wireless anchor network, and
wherein the tag to anchor communication operates on a schedule that is independent from a schedule for operation of the wireless anchor network.
