Estimating the term…
Wireless devices, systems and approaches or methods having the capability of determining the location of a given wireless device. An example system includes a wireless device that generates at least one pulse as a part of an output signal, and the at least one pulse is captured by anchor devices and used, in a time of arrival approach, to determine the location of the example device. The at least one pulse may be generated during a designated portion of an otherwise normally modulated message. Another example system includes an anchor node that generates a directional output signal, the direction output signal including data indicating its direction, and the directions of output signals from plural anchor nodes when pointed at a wireless device are used to determine the location of the wireless device. Combinations of the pulse and directional antenna systems, devices used within each of these systems, and approaches associated with these systems are also included.
A method of determining the location of a wireless device, the method comprising:
A wireless device comprising generating circuitry that generates a carrier signal, and modulating circuitry that modulates the carrier signal relative to data for transmission in accordance with a predetermined modulation communication protocol to generate a signal for transmission, the device further comprising pulse creation circuitry adapted to selectively create one or more pulses in association with the signal for transmission, the one or more pulses being generated and applied in a manner inconsistent with the predetermined modulation communication protocol associated with modulation of the carrier signal by the modulating circuitry, resulting in one or more pulses disposed in the signal for transmission.
A wireless communication system comprising:
