Abstract: In a general aspect, motion is detected using wireless signals. In one example, beamforming dynamic information is obtained based on a set of wireless signals transmitted through a space from a first wireless communication device to a second wireless communication device. Motion of an object in the space is detected based on the beamforming dynamic information.

Abstract: In a general aspect, motion is detected using wireless signals. In one example, a wireless signal transmitted through a space from a first wireless communication device is received at a second wireless communication device. Dynamic beamforming information is based on the wireless signal. The second wireless communication device uses the dynamic beamforming information to detect motion in the space, or transmits the dynamic beamforming information to the first wireless communication device for use in detecting motion in the space.

Abstract: In a general aspect, motion is detected using wireless signals. In one example, a wireless standard protocol message is transmitted by a wireless communication device through a space to one or more neighbor devices. A corresponding wireless standard protocol response including beamforming information feedback is received from each of the one or more neighbor devices in response to the wireless standard protocol message. Motion of an object in the space is detected based on the beamforming information feedback from each of the neighbor devices.

Abstract: In some cases, a wireless sensor device includes a radio frequency (RF) processor system. The RF processor system includes a forward error correction (FEC) device, a digital signal processor (DSP) device and a shared memory device that is connected between the FEC device and the DSP device. The DSP device is directly connected to the shared memory device and configured to selectively access individual memory elements of the shared memory device. The FEC device is directly connected to the shared memory device and configured to collectively access arrays of memory elements of the shared memory device.

Abstract: In some aspects of what is described, a wireless sensor device includes a radio frequency (RF) processor system. The RF processor system includes a very large instruction word (VLIW) processor device that has multiple execution units. The RF processor system also includes storage units and an interconnect device. The storage units store instruction words to be routed to the execution units. The interconnect device provides connectivity between the storage units and the execution units. The interconnect device is adapted to route instruction words from storage units to respective execution units according to routing indices for each clock cycle of the VLIW device.
