Abstract
An autonomous system with no Customer Network Investment is described, wherein the system is configurable to operate on in a band in addition to the LTE band. Such system allows the definition of hybrid operations to accommodate the positioning reference signals (PRS) of LTE and already existing reference signals. The system can operate with PRS, with other reference signals such as cell-specific reference signals (CRS), or with both signal types. As such, the system provides the advantage of allowing network operator(s) to dynamically choose between modes of operation depending on circumstances, such as network throughput and compatibility.
Claims21
A method for tracking and locating one or more wireless network devices in communication with a network, comprising:
- collecting at a node in the network information regarding a reference signal or a plurality of known signal samples;
- without processing the collected information for location calculation purposes at the node, sending the collected information from the node to a locate server unit;
- and
- calculating at the locate server unit a location of each in range wireless network device based on the collected information.
