Dispelling the Myths Associated with Spread Spectrum Radio Technology in Electric Power SCADA Networks

Abstract

Every year the electric power industry deploys more spread spectrum communication solutions. As recently as five years ago, the telemetry of electric power data was almost exclusively in the licensed radio realm. However, the scarcity of available licensed channels as well as its improved technology has made the spread spectrum radio an increasingly popular choice. With the install base of spread spectrum devices rapidly increasing, there have been a number of "urban legends" or "superstitions and myths" that have circulated. With the introduction and advancement of any new technology, misconceptions and misunderstandings will always surface. Spread spectrum, like any technology, can be an extremely valuable tool when used in the correct environment and with correct deployment. The objective of this article is to explore these "myths" and provide a better understanding of how to use spread spectrum technology and also show where you can expect to succeed with spread spectrum communication solutions.
