Abstract: 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.

Abstract: 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 via one or more transmit antennas, and to send a timing-synchronization signal over an internal interface. The WLAN receiver is configured to receive, via one or more receive antennas, echo packets including reflections from an object of a selected subset of the WLAN packets transmitted by the WLAN transmitter, to receive the timing-synchronization signal from the WLAN transmitter over the internal interface, and to time-synchronize the echo packets and the corresponding WLAN packets using the timing-synchronization signal. The processor is configured to estimate one or more parameters of the object based on the time-synchronized echo packets and WLAN packets, and to output the estimated parameters to a user.

Abstract: A method for communication includes modulating a stream of data in accordance with a voice-band modem specification, so as to generate a modulated signal. The modulated signal is up-shifted to generate a passband signal, which is transmitted over a telephone line simultaneously with a baseband voice signal.

Abstract: Apparatus for data communication includes a transmitter, which is adapted to generate a sequence of symbols at a variable symbol rate, responsively to a stream of digital data, and to convert the sequence to an analog data signal for transmission over a communication medium. A receiver includes an analog/digital converter (ADC), which is adapted to receive and digitize the data signal at a variable sampling rate so as to generate a sequence of digital samples, and digital processing circuitry, which is coupled to process the digital samples so as to extract the stream of digital data therefrom. The transmitter and the receiver are adapted to negotiate over the communication medium so as to set the sampling rate of the ADC and to determine the symbol rate responsively to the sampling rate.

Abstract: Briefly, in one example of the present invention, a modem has a modem controller able to generate signals to enable coexistence of a modem session and a voice call. The modem also has a relay to connect and disconnect a handset jack from a data access arrangement (DAA) according to the signals.
