Abstract: During an ongoing wireless telephone call communication session between a pair of mobile devices, a local device responds to its user's activation of a virtual or actual button or key, or its user's verbal command, by automatically sending an over the air message (e.g., a SMS or text message or other network communication message) to the remote device. The message requests location information of the remote device. Upon obtaining location information from the remote device, a location of the remote device is automatically displayed on the local device. Other embodiments are also described and claimed.

Abstract: Wireless electronic devices may include wireless communications circuitry such as a transceiver, antenna, and other wireless circuitry. The transceiver may be coupled to the antenna through a bidirectional switch connector. The switch connector may mate with a corresponding radio-frequency test probe that is connected to radio-frequency test equipment. When the test probe is mated with the switch connector, the transceiver may be decoupled from the antenna. During transceiver testing, radio-frequency test signals may be conveyed between the test unit and the transceiver using the test probe. During antenna testing, radio-frequency test signals may be conveyed between the test unit and the antenna using the test probe. Transceiver testing and antenna testing may, if desired, be conducted in parallel using the test probe.

Abstract: Electronic devices with wireless communications capabilities are provided. The electronic device may include storage and processing circuitry, power amplifier circuitry, power supply circuitry, etc. The storage and processing circuitry may direct the power amplifier circuitry to operate using a desired gain mode, in a particular radio channel, and at a given output power level. The power supply circuitry may bias the power amplifier circuitry with a power supply voltage. The performance of the power amplifier circuitry may be characterized by an adjacent channel leakage ratio (ACLR) margin. The power consumption of the power amplifier circuitry may be characterized by a current savings ratio. A cost function may be calculated by taking the product of the ACLR margin and current savings ratio. A minimum point for each cost function curve may be determined. It is desirable to bias the power amplifier circuitry with a supply voltage corresponding to the minimum point.

Abstract: Calibration equipment for calibrating multiple test stations in a test system is provided. Each test station may include a test unit, a test fixture, and a radio-frequency (RF) cable that connects the test unit to the test fixture. A control test setup may be used to calibrate uplink and downlink characteristics associated with each test station (e.g., to determine path loss associated with the RF cable and test fixture and variations associated with the test unit). The control test setup may calibrate each test station at desired frequencies to generate a test station error (offset) table. The test unit of each test station may be individually configured based on the test station error table so that offset is minimized among the different stations and so that the test stations may reliably measure hundreds or thousands of wireless electronic devices during product testing.

Abstract: A wireless electronic device such as a portable electronic device may contain a baseband module. Power amplifier circuitry in the device may amplify radio-frequency signals for transmission. During calibration measurements, a computer directs the baseband module to generate control signals that adjust the gain of the power amplifier circuitry. The computer may also direct the baseband module to generate a series of modulated or unmodulated test tones at one or more communications channel frequencies. A power sensor may be connected to the output of the power amplifier circuitry using a transmission line path. The computer and power sensor may be used in making power measurements on radio-frequency signals at the output of the power amplifier while power amplifier gain and test tone frequency adjustments are being made. Power amplifier calibration data may be produced and stored in the electronic device based on the power measurements.

Abstract: A test station may include a test host, a signal generator, and a test chamber. Multiple devices under test (DUTs) may be placed in the test chamber during production testing. Radio-frequency signals may be conveyed from the signal generator to the multiple DUTs using a conducted arrangement through a radio-frequency signal splitter circuit or using a radiated arrangement through an antenna in the test chamber. The signal generator may broadcast initialization downlink signals. The multiple DUTs may synchronize with the initialing downlink signals. The signal generator may broadcast test downlink signals at a target output power level. The multiple DUTs may receive the test downlink signals and compute a corresponding downlink transmission performance level based on the received downlink signals. A given DUT is marked as a passing DUT if the downlink performance level is satisfactory. A given DUT may be retested if the downlink performance level fails design criteria.

Abstract: A portable handheld electronic device contains a camera lens and accelerometer to allow a user to control voicemail and call features by swiping his finger across the camera lens and/or tapping the device. Therefore, the user can comfortably input commands into the device with a single hand and without needing to move the phone away from his ear to apply these inputs. In another embodiment, the camera lens can also be used to control navigation of the display screen or a displayed document of the device. For example, if a user wishes to shift a scrollbar for a page displayed on the screen downwards to view the bottom of the page, the user should move his finger over the camera lens in an analogous downward direction.

Abstract: A system for performing wireless local area network testing of wireless devices may include a wireless local area network tester and a device under test. The tester and device under test may communicate over a wireless link. To ensure that the tester accurately analyzes test data, a data rate table is used that specifies fixed data transmission rates to be used by the device under test under both high-quality link conditions and low-quality link conditions. This forces the device under test to transmit control packets at the same high data rate during packet loopback testing, regardless of link quality. When the captured control packets are analyzed at the tester, both low-link-quality data and high-link-quality data may be analyzed using a common test template, ensuring accurate results.

Abstract: Wireless test equipment may be used to perform over-the-air testing of user equipment. The user equipment may contain an antenna and a receiver. The wireless test equipment may contain a call box that performs network-level testing by sending and receiving protocol-compliant network messages. The call box may transmit a radio-frequency test signal at a predetermined power. The antenna in the user equipment may receive the radio-frequency test signal and may provide the received radio-frequency test signal to the input of the receiver. The call box may send a network message such as a code-division-multiple-access intercode handover command to the user equipment to direct the user equipment to measure the received radio-frequency test signal power at the input of the receiver. The measured power may be transmitted to the call box as part of a pilot measurement message indicator, using an intercode handover command, or using other network messages.

Abstract: Calibration equipment for calibrating multiple test stations in a test system is provided. Each test station may include a test unit, a test chamber with an over-the-air antenna, and a radio-frequency (RF) cable that connects the test unit to the test chamber. Reference devices under test (DUTs) may be used to calibrate uplink and downlink path loss (e.g., OTA path loss, RF cable path loss, and variations of the test unit) associated with each test station. The reference DUTs may calibrate each test station at desired frequencies to generate a path loss table. Once calibrated, the test chambers may be used during production testing to test factory DUTs. During production testing, the transmit/receive power efficiency of each factory DUT may be calculated based on values in the path loss table to determine whether a particular production DUT is a passing or failing DUT according to pass/fail criteria.

Each test station may include a test unit, a test chamber with an over-the-air (OTA) antenna, and a radio-frequency (RF) cable that connects the test unit to the test chamber. Reference devices under test (DUTs) may be used to calibrate the OTA path loss of each test station at desired frequencies. Once calibrated, the test chambers may be used during production testing to test factory DUTs to determine whether a particular production DUT is a passing or failing DUT according to pass/fail criteria. A running average path loss value may be constantly updated based on path loss values measured using the reference DUTs and the passing production DUTs. Dynamically updating the path loss value using this statistical approach can properly track the behavior of each test station as operating conditions shift over time.

Abstract: A test station may include a test host, a signal generator, and a test chamber. Multiple devices under test (DUTs) may be placed in the test chamber during device characterization operations. Radio-frequency signals may be conveyed from the signal generator to the multiple DUTs using a radiated arrangement through an antenna in the test chamber. The signal generator may broadcast downlink test signals. The DUTs may synchronize with the downlink test signals and measure radio-frequency performance levels while receiving the downlink test signals. The test host may direct the signal generator to gradually lower its output power level. The DUTs may be used to determine downlink sensitivity by monitoring the measured radio-frequency performance levels as the output power level of the signal generator is lowered. Downlink sensitivity testing may be performed across any desired radio-frequency bands and channels.

Abstract: Wireless electronic devices may include a transceiver, an antenna resonating element coupled to the transceiver via a transmission line path, transceiver and antenna impedance matching circuits, and other circuitry. The transceiver and the impedance matching circuits may be formed on a first substrate. The antenna resonating element may be formed using a second substrate. The antenna resonating element may be decoupled from the first substrate during testing. First and second sets of test points may be formed at first and second locations long the transmission line path. During testing, a test probe may mate with the first set of test points, whereas an impedance adjustment circuit that serves to electrically isolate the antenna impedance matching circuit from the transceiver may mate with the second set of test points. The impedance adjustment circuit need not be used if the antenna impedance matching circuit is decoupled from the transceiver during testing.
