Abstract
An arrangement for use in a utility meter includes a non-volatile memory and an RF transceiver. The non-volatile memory has a first and a second port, the first port configured to obtain commodity consumption data. The radio frequency (RF) transceiver is configured to receive and RF signal from an external source and obtain energy from the RF signal and provide the energy to a bias voltage input of the non-volatile memory. The RF transceiver is further operable to perform a data transfer operation responsive to the received RF signal, the data transfer operation including a transfer of meter-related data between the non-volatile memory and the RF transceiver using the second port of the non-volatile memory.
