    摘要： An RF transceiver includes a configuration controller that generates a control signal to select a first candidate radiation pattern for a beamforming antenna based on a first plurality of steering weights. An RF transceiver section broadcasts a first beacon transmission with the first candidate radiation pattern, and generates feedback signals to indicate if a first remote station has responded to the first beacon transmission. When the first remote station has responded to the first beacon transmission, the configuration controller stores the first plurality of steering weights used in association with the beacon transmission and generates control signals to the RF transceiver section to use the first candidate radiation pattern when communicating with the first remote station.

    摘要： Methods and systems for stabilizing a GNSS clock by reducing interference are disclosed and may include stabilizing a frequency of a temperature compensated crystal oscillator (TCXO) on a chip in a GNSS device. A clock signal may be generated for the device by temporarily configuring circuitry adjacent to the TCXO at a constant power level. Temperature and electromagnetic interference of the TCXO may be stabilized by the constant power level of the adjacent circuitry, which may be on the chip or external to the chip. The frequency of the TCXO may be stabilized by temporarily disabling the adjacent circuitry. A GNSS clock signal may be stabilized by the configuring of the constant power level while a GNSS location may be calibrated. A GNSS location of a fixed wireless device, such as a wireless access point, may be calibrated utilizing the configured constant power level and shared with other wireless devices.
