System and method for communication between remote locations
First Claim
1. A method of remote communication in a code-division multiple access (CDMA) communication system in which a first relay having a CDMA communication link communicates with a communication device and a control station, said CDMA communication link carrying a plurality of data, said method comprising the steps of:
- measuring, at said communication device, a local parameter;
transmitting, from said communication device, data over said CDMA communication link corresponding to said measurement;
receiving, in said control station, said data corresponding to said measurement;
generating, in said control station, data;
transmitting said data generated in said control station over said CDMA communication link; and
receiving, in said communication device, said data transmitted from said control station;
wherein said CDMA communication system further includes at least one power line extending over at least a portion of said CDMA communication system from said communication device to said first relay, said method further comprising the steps of;
translating said data into a power-line carrier control signal; and
transmitting said power-line carrier control signal over said at least one power line.

Abstract
A communication system transmits data between a plurality of locations. The communication system is suitable for use by a utility provider to monitor a plurality of metering devices from a remote location. The communication system in accordance with use by a utility provider to monitor metering devices comprises a control for at least receiving data, a plurality of metering devices arranged in a defined number of metering groups for transmitting data associated with an amount of usage of a utility, and a defined number of concentrators, each operably connected to the control and one metering group for transmission of data between the control and plurality of metering devices.
