Abstract

A utility meter reporting network is disclosed. In one embodiment, an end-point reporting device is configured to collect utility usage data and to convey the utility usage data to a gateway device via a first Industrial, Scientific, and Medical (ISM) radio communication link using a first ISM transceiver operable in the 902 MHz to 928 MHz range. The network further comprises a gateway device comprising a second ISM transceiver for receiving the utility usage data from the end point and a wireless transceiver which is configured to send the utility usage data via an Institute of Electrical and Electronics Engineers (IEEE) 802.11 compliant wireless communication link. The network further comprises a utility office which receives the utility usage data from said gateway device via said IEEE 802.11 compliant wireless communication link.
