WiFi transceivers detects and iTagPro features traces motion whereas WiFi transceivers are naturally transmitting packets for communication. Therefore, tracing performance may be piggybacked on current WiFi alerts and use current WiFi spectrum without compromising communication or throughput. One embodiment is capable of tracing independent motion of a number of objects. One embodiment is able to detecting and tracing motion of one or more people that independently perform units of effective-grained movements. Therefore, in accordance to one embodiment, radio frequency transceivers, equivalent to WiFi transceivers can be used as accurate, occlusion resistant, high resolution movement cameras able to working in low mild or dark circumstances. FIG. 1 illustrates an instance dwelling situation, iTagPro geofencing wherein radio signals (e.g., WiFi indicators) are scattered by objects, according to 1 embodiment of the current invention. FIG. 1 illustrates an instance home scenario, in which radio signals (e.g., WiFi signals) are scattered by objects, according to one embodiment of the present invention.
WiFi AP is being used for accessing the Internet, which is for instance a 4-antenna 802.11ac AP. AP receives backscatter reflections from a close by reflector iTagPro geofencing (e.g., the monitor), as effectively as the faraway reflectors, resembling fingers of individual B. Because of the distinction in distance, as well as the truth that faraway backscatter signal has to reflect off or journey by partitions, iTagPro tracker there is a considerable difference in signal strength between the 2 backscatter components. As described below, one embodiment supplies a method to capture and/or estimate weak backscatter signals. As illustrated in FIG. 1 , the AP receives many backscatter reflections, out of which only some correspond to reflections from the moving objects. The reason being the nice propagation properties of WiFi frequencies and the abundance of reflectors in indoor iTagPro geofencing environments. Many objects corresponding to drywalls, tables, iTagPro website chair, laptops and floors replicate indicators on the 2.Four GHz and 5 GHz frequencies. The problem is to determine the backscatter signals which are mirrored from the moving objects amongst these multitude of backscatter components.
FIG. 2 illustrates an example movement detection/tracing system, according to at least one embodiment. 202 and iTagPro geofencing N transceivers 204 1 via 204 N . WiFi transceivers which can be capable of tracing and iTagPro technology tacking motion could also be disposed in a room. Each of the transceivers may transmit a radio frequency sign and receive backscatter alerts from objects in the environment. 206 and a number of static objects 208 could also be situated in the surroundings that reflect the radio frequency signals transmitted by the transceivers 204 1 through 204 N . 206 and ship the estimated parameters to server 202 for more processing. 202 isolates the backscatter generated by shifting objects, and traces the motion after combining the measurements from all of the transceivers.
