Abstract:
Techniques for dynamic power control of a radio of a utility data collection device (e.g., utility meter configured for wireless communications) are described that utilize a detection scheme applied to a Front End Module (FEM) in the utility data collection device. A utility data collection device measures a Voltage Standing Wave Ratio (VSWR) presented to the FEM during transmission. The result of this measurement allows the utility data collection device to dynamically control the input power to a FEM transmit portion. Utilizing these techniques, the utility data collection device can adjust to environmental changes and conditions experienced in the field.
