RF MEASUREMENT AND USE AND CELL LAN PROTOCOL / Node This technology relates to protocols for utility meters associated with an open operational structure. More closely, this subject refers to a protocol subject for an advanced measurement infrastructure, adaptable to various international standards, while economically supporting a 2-way mesh network solution in a wireless environment, such as for operation in a residential electricity meter field. This subject supports meters in an ANSI standard C12.22 / C12.19 system, while economically supporting a 2-way mesh network solution in a wireless environment, such as for operation in a meter field. residential electricity, all to allow for a cell-based adaptive insertion of C12.22 meters into an open structure. Cell isolation is provided through quasi-orthogonal sequences in a frequency hopping network. Additional features refer to real-time clock distribution and retrieval, uplink routing without requiring a routing table, and the handling of Signal Guidance Requests and Registered State bit resolution to avoid circular routes . Features regarding cell or node usage or management on a mesh network include cell size management, Number of children management, offsetting difference between the current reading and a crystal reference on a mesh network, broadcast recognition, and Traffic Load Control on a Mesh Network. Other features refer to features of the environmental assessment tool for measuring the need for performance of RF transceivers, downlink routing mechanisms, out-of-supply notification system features, the use of a minimum propagation delay path for optimization of the mesh network, and operation at the node level of a Discovery Phase in a frequency hopping network. |
