Abstract
A method and apparatus is disclosed for adjusting a transmission power level of a transceiver (12, 15) at a utility meter data origination site (10). A power level of transmission at the site transceiver (12, 15) is adjusted to an optimum level if an acknowledgement is not received from a network gateway (30) in response to data transmissions from the site transceiver (12, 15). Also, for each unsuccessful transmission period, the amount of metering data is increased in the next transmission period to make up for the failed communication tries. Upon establishing communication with the gateway (30), the site transceiver (12, 15) can receive commands from the gateway (30) that further adjust its power level of transmission to optimize reception at the gateway from a large plurality of utility meter data origination sites (10) within a geographical area served by the gateway (30). The gateway (30) communicates utility metering data through a wireless network (40), such as WIFI, GPRS, POE or CDMA to a data collection center (50) for data processing and billing operations.
