Abstract

A method and system for transmitting, receiving, and collecting information related to a plurality of working components, such as street lamps, allows for efficient and effective monitoring and controlling of working components through short-distance radio communications at low power levels. In a preferred implementation of the present invention, a communications network includes a plurality of transceiver modules, each of which is secured and operably connected to a working component. These transceiver modules transmit and receive radio communications or “messages” representative of the status of the working component from one another in a controlled manner, with each message ultimately being directed to an area control module. At the area control module, the messages are collected and transferred to a network support server, which analyzes the information and data contained in such messages, and then transfers such information and data to control and display units through a computer network for review by end users. The control and display units further allow for control of the working components by initiating transmission of radio communications containing instructions or programming code to one or more particular transceiver modules.
