Abstract: A system and method for speed measurement of a mobile device (300), using a speed sensor (460) such as a satellite navigation system (460) or an accelerometer, does not need such speed sensor (460) to be continually activated. The system and method make use of a monitor (471) for monitoring at least one motion indicium for indicating that the speed of the mobile device (300) is above an initial threshold (112), including but not limited to: monitoring the Doppler shift measurements of a timing signal; monitoring the timing advance of a cellular radio signal; monitoring the number of base stations (511) visible to the mobile device (300); monitoring the frequency of base station handover, however determined; monitoring the level crossings and/or the autocorrelation of an RSSI signal; and/or triangulation of the position of the mobile device (300). When the monitor (471) determines that the mobile device (300) may be travelling in excess of a threshold speed (112), a speed sensor (460) is activated to confirm the indication. If the speed sensor (460) determines that the mobile device (300) is travelling at a speed below a second threshold (171), the speed sensor (460) is deactivated.

Abstract: A mobile wireless communications device includes a housing an antenna, and radio frequency (RF) circuitry. A transceiver is connected to the antenna and a processor is operative with the RF circuitry. The transceiver includes an In-phase and Quadrature (I/Q) Modulation and Power Amplification circuit having an In-phase (I) circuit with a modulator mixer and power amplifier circuit. A Quadrature (Q) circuit includes a modulator mixer and power amplifier circuit. A power combiner receives the separately amplified In-phase and Quadrature signals and sums and outputs the signals as a combined I and Q signal. The I and Q circuits are isolated from the combined I and Q signal to enhance antenna matching and transmitted radiated power (TRP) and reduce harmonic emission from the power amplification circuits.

Abstract: A test method is for determining RF sensitivity of an RF receiver (132) for a plurality of channels extending over a frequency band(s) using an RF source (131) coupled to the RF receiver by an RF communications link (133). The plurality of channels may include channels having a predictable RF sensitivity and a channel(s) having a non-predictable RF sensitivity. The test method may include measuring an RF sensitivity for one or more of the channels having the predictable RF sensitivity, and generating a partial RF sensitivity function for the channels having the predictable RF sensitivity based thereon. The method may further include measuring an RF sensitivity for the channel(s) having the non-predictable RF sensitivity. Additionally, an overall RF sensitivity function may be generated for the plurality of channels based upon the partial RF sensitivity function, and based upon the measured RF sensitivity for the channel(s) having the nonpredictable RF sensitivity.
