Abstract: Certain embodiments are directed to techniques (e.g., a device, a method, or a non-transitory computer readable medium storing code or instructions executable by one or more processors) for many-to-many communication techniques for coordinating communications among a group of mobile devices that can be performed by a first mobile devices. The first mobile device can transmit a request to establish outgoing pairwise ranging sessions with other mobile devices of the group. Each of the mobile devices of the group of mobile devices can establish ranging sessions with the other mobile devices. Each mobile device can act as both an initiating device and a responding device for the ranging session. The first mobile device can detect one or more redundant ranging sessions the mobile devices. The first mobile device can identify whether to keep or terminate each of the one or more redundant ranging sessions based on a common criterion.

Abstract: A system and method for highly selective intrusion detection using a sparse array of ultra wideband (UWB) radars. Two or more UWB radars are arranged in a sparse array around an area to be protected. Each UWB radar transmits ultra wideband pulses that illuminate the area to be protected. Signal return data is processed to determine, among other things, whether an alarm condition has been triggered. High resolution radar images are formed that give an accurate picture of the area to be protected. This image is used to detect motion in a highly selective manner and to track moving objects within the protected area. Motion can be distinguished based on criteria appropriate to the environment in which the intrusion detection system operates.
