Electric monitoring system using a random phase multiple access system

Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, are configured for receiving monitor data from an electric meter. A data stream is created based upon the monitor data. The data stream is spread with a common pseudo-noise (PN) code that is used by a...

Zusammenfassung:	Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, are configured for receiving monitor data from an electric meter. A data stream is created based upon the monitor data. The data stream is spread with a common pseudo-noise (PN) code that is used by a plurality of nodes in communication with an access point. The spread data stream is transmitted at a first time based on a slot start time and a first randomly selected timing offset. The spread data stream is transmitted while at least a portion of a second spread data stream is transmitted at a second time based on the slot start time and a second randomly selected timing offset. The second spread data stream is spread with the common PN code.
