Programming electronic meter settings using a bandwidth limited communications channel
First Claim
1. A system for communicating data to a electronic meter over a bandwidth limited network, comprising:
- a controller having a network scheduler;
a radio interface at said electronic meter that receives said data from said controller; and
a network interface at said node that processes said data, wherein said controller communicates said data in pieces to said electronic meter, and wherein said network interface stores each piece in memory such that the pieces are combined in a memory buffer to be executed together within said electronic meter.

Abstract
A system for transferring a sequence of actions to an electronic meter through a bandwidth limited communications channel. The sequence of actions is programmed as a program file that is broken into pieces for transmission to the electronic meter. The pieces are received by the electronic meter, verified not to contain errors, and combined into a single program session. Any errors in the transmission are noted in a status table and the program file is retransmitted. Upon receipt of an execute command, the program session is commenced. After the session has completed the status table is updated. Thus, the electronic meter may be programmed in a programming session that contains more data than can be transferred via the bandwidth limited communications channel.
