Energy suppliers rely on Supervisory Control and Data Acquisition (SCADA) systems to enable remote telemetry functions in the power grid. Historically, SCADA systems have employed wireline networks to link remote power grid elements with a central operations center. Today, more and more utilities are turning to public cellular networks to provide these vital communications functions. Modern cellular networks are just as secure and reliable as wireline infrastructure, and can be faster, easier, and less expensive to deploy and operate.
This paper examines the benefits of wireless communications in SCADA systems, and offers guidance on building a successful wireless-enabled SCADA system.
