1. A computer-implemented method of determining a location of a mobile computing device, the method comprising:
determining, by a mobile computing device, a first location of the mobile computing device;
responsive to determining the first location, requesting, by the mobile computing device, acoustic-contextual data from a real-time locating system, the acoustic-contextual data associated with the first location of the mobile computing device, the acoustic-contextual data comprising first data associated with one or more transmitting devices, the one or more transmitting devices being a part of an infrastructure of the real-time locating system, and second data associated with an environment proximate the one or more transmitting devices;
receiving, by the mobile computing device, the requested acoustic-contextual data from the real-time locating system, the acoustic contextual data being transmitted via a network associated with the real-time locating system;
receiving, by the mobile computing device, one or more acoustic signals from at least one of the one or more transmitting devices; and
determining, by the mobile computing device, a second location of the mobile computing device based at least in part on the acoustic-contextual data and the one or more received acoustic signals,
wherein an accuracy of the second location of the mobile computing device exceeds an accuracy of the first location of the mobile computing device.
