Classification: CPC G  H | IPC G  H

Claim 7:
8. A method associated with a real-time locating system, the method comprising:
transmitting, by a first transducer, first acoustic signals having a first frequency, the first acoustic signals including an identifying code of a transmitting device, wherein the identifying code represents a location of the transmitting device;
transmitting, by a second transducer, second acoustic signals having a second frequency, the second acoustic signals including the identifying code of the transmitting device, wherein the identifying code represents the location of the transmitting device;
transmitting, by a beacon device, beacon data via a short-range wireless communication technique, wherein the beacon data includes a time offset value and information that may be used by a receiving device in decoding the transmitted acoustic signals, the information describing a subset of identifying codes in use in a vicinity of the beacon device, wherein the identifying code is a member of the subset of identifying codes, and wherein the time offset value may be used by the receiving device to adjust its timing of receipt of either RF or acoustic receptions; and
selecting, by one or more control devices, the first or second acoustic signals based at least in part on one or more operating capabilities of one or more mobile units associated with the real-time locating system, and causing transmission of the selected acoustic signals and the beacon data,
wherein the first transducer, the second transducer, the beacon device and the one or more control devices form a part of the real-time locating system.
