METERING RF LAN PROTOCOL AND CELL/NODE UTILIZATION AND MANAGEMENT |
摘要 |
<p>The present technology relates to protocols relative to utility meters associated with an open operational framework. More particularly, the present subject matter relates to protocol subject matter for advanced metering infrastructure, adaptable to various international standards, while economically supporting a 2-way mesh network solution in a wireless environment, such as for operating in a residential electricity meter field. The present subject matter supports meters within an ANSI standard C12.22/C12.19 system while economically supporting a 2-way mesh network solution in a wireless environment, such as for operating in a residential electricity meter field, all to permit cell-based adaptive insertion of C12.22 meters within an open framework. Cell isolation is provided through quasi-orthogonal sequences in a frequency hopping network. Additional features relate to real time clock distribution and recovery, uplink routing without requiring a routing table, and the handling of Beacon Requests and Registered State bit resolving to avoid circular routes.</p> |
