SYSTEM AND METHOD FOR POSITIONING AND TRACKING MOBILES WITHIN A STRUCTURE
First Claim
1. A method for positioning and tracking mobiles within an infrastructure, the method comprising:
- transmitting, from a first aerial, a first signal generated in accordance with a first characteristic for addressing specifically a first one of the mobiles, and the first aerial being located at a pre-determined position outside of the infrastructure;
upon receiving the first signal and detecting the first characteristic, the first mobile generating and transmitting a second signal with a second characteristic different from the first characteristic;
receiving, at the first aerial and at each one of at least three additional aerials, the second signal at respective reception times, the at least three additional aerials located at respective pre-determined positions outside of the infrastructure;
determining a position of the first mobile based on;
the respective reception times;
the pre-determined position of the first aerial; and
the respective pre-determined positions of the at least three additional aerials; and
outputting the position of the first mobile to a display device, for display relative to a given location.

Abstract
Method and a system for positioning and tracking a mobile within an infrastructure. The method includes transmitting, from a first aerial, a first signal generated in accordance with a first characteristic for addressing specifically a first mobile, and the first aerial located at a position outside of the infrastructure; upon receiving the first signal and detecting the first characteristic, the first mobile generating and transmitting a second signal with a second characteristic; receiving, at the first aerial and other additional aerials, the second signal at respective reception times, the other aerials located at respective pre-determined positions outside of the infrastructure; determining a position of the first mobile based on: the respective reception times; the position of the first aerial; and the respective positions of the other aerials; and outputting the position of the first mobile to a display device, for display relative to a given location.

19. A system for positioning and tracking mobiles within an infrastructure, the system comprising:
-
a mobile free to be moved throughout the infrastructure; a transceiving device and at least three receiving devices located at respective pre-determined positions outside of the infrastructure, the transceiving device for transmitting a first signal generated in accordance with a first characteristic for addressing specifically the mobile, and each one of the transceiving devices and the at least three receiving devices for receiving at respective reception times a second signal sent from the mobile; a positioning module for determining a position of the mobile within the infrastructure based on the respective reception times and the respective pre-determined positions; and an output device for communication with the positioning module, and for outputting the position of the mobile, wherein the mobile generates and transmits the second signal upon detecting the first characteristic of the first signal, the second signal having a second characteristic different from the first characteristic. - View Dependent Claims (20, 21, 22)

23. In a processor device, a method for positioning and tracking mobiles within an infrastructure, the method comprising:
-
sending a first command to a first aerial, the first command instructing the first aerial to transmit a first signal with a first characteristic for addressing specifically a first one of the mobiles, the first aerial being located at a pre-determined position outside of the infrastructure; receiving from the first aerial and each one of at least three additional aerials, respective reception times at which a second signal is respectively received, the second signal being generated by the first mobile upon the first mobile detecting the first characteristic of the first signal, the second signal having a second characteristic different from the first characteristic, and the at least three additional aerials being located at respective pre-determined positions outside of the infrastructure; determining a position of the first mobile based on;
the respective reception times;
the pre-determined position of the first aerial; and
the respective pre-determined positions of the at least three additional aerials; andoutputting the position of the first mobile to a display device, for display relative to a given location. - View Dependent Claims (24, 25, 26, 27)

28. A system for positioning and tracking mobiles within an infrastructure, the system comprising:
-
a processor device for communication with a memory device; a display device for communication with the processor device; and an application module comprising instructions, stored within the memory device, for allowing the processor device to; send a first command to a first aerial, the first command instructing the first aerial to transmit a first signal with a first characteristic for addressing specifically a first one of the mobiles, the first aerial being located at a pre-determined position outside of the infrastructure; receive from the first aerial and each one of at least three additional aerials, respective reception times at which a second signal is respectively received, the second signal being generated by the first mobile upon the first mobile detecting the first characteristic of the first signal, the second signal having a second characteristic different from the first characteristic, and the at least three additional aerials being located at respective pre-determined positions outside of the infrastructure; determine a position of the first mobile based on;
the respective reception times;
the pre-determined position of the first aerial; and
the respective pre-determined positions of the at least three additional aerials; andoutput the position of the first mobile to the display device, for display relative to a given location.
