摘要： A wireless device includes multiple RF chains, one or more processing modules, a switching circuit and a processor. The RF chains operate in multiple RF bands, and at least one RF chain is configurable to operate at a RF band selected from the RF bands. The processing modules are configurable to process signals communicated with the RF chains. The switching circuit routes signals between RF chains and processing modules in accordance with a routing plan. In response to an event that warrants reconfiguration, the processor re-allocates resources, including (i) allocating one or more RF chains to respective RF bands, (ii) allocating one or more processing modules to process signals associated with the RF bands, and (iii) setting the routing plan to route signals between pairs of RF chains and processing modules allocated to a common RF band. The processor communicates wirelessly with remote devices in accordance with the operational reconfiguration.

摘要： A Wireless Local-Area Network (WLAN) access point includes a WLAN transmitter, a WLAN receiver, and a processor. The WLAN transmitter is configured to transmit WLAN packets and to send a timing-synchronization signal. The WLAN receiver is configured to receive echo packets including reflections from an object of the transmitted WLAN packets, to receive the timing-synchronization signal, and to time-synchronize the echo packets and the corresponding WLAN packets. The processor is configured to (a) in response to a gap in the received echo packets, generate one or more synthetic echo packets by interpolating over two or more of the time-synchronized received echo packets, to consequently derive a sequence of equally-spaced echo packets, (b) using the derived sequence of equally-spaced echo packets and the WLAN packets estimate one or more parameters of the object, and (c) output the estimated parameters to a user.

摘要： A method for estimating a location of a target Wireless Local-Area Network (WLAN) device includes obtaining relative locations of three or more WLAN devices. Respective distances are measured between each of the WLAN devices and the target WLAN device. The location of the target WLAN device is estimated based on the locations of the WLAN devices and on the measured distances, wherein measuring a distance between a WLAN device and the target WLAN device includes: exchanging WLAN signals, detecting a first leakage signal by a receiver of the WLAN device, detecting a second leakage signal by the receiver of the target WLAN device, calculating time differences between a time a WLAN signal was sent and a time a leakage signal was detected, and subtracting the time differences one from the other to obtain a time-of-flight that corresponds to the distance between the WLAN device and the target WLAN device.

摘要： A wireless device (24) includes a modem (56) and processing circuitry (50, 52). The modem is configured to modulate signals for transmission over wireless channels, and demodulate signals received over the wireless channels. The processing circuitry is configured to receive a first frame from a second wireless device over a wireless channel via the modem, and transmit a second frame to the second wireless device via the modem over the wireless channel, to calculate a first Channel State Information (CSI) based on the first frame, to calculate a first normalized CSI by applying to the first CSI a normalization procedure, and generate, based on the first normalized CSI, a first key that due to the normalization procedure has an increased likelihood to match a second key generated in the second wireless device based on the second frame, and to communicate securely with the second wireless device over the wireless channel using the first key.
