Scada uses radio to bridge the gap

Describes how radio telemetry can interface with process control systems such as supervisory control and data acquisition [SCADA] and distributed control systems [DCS] greatly increasing their power and efficiency. Outlines the basis of radio telemetry, the behaviour of electromagnetic waves,frequency and wavelengths. Uses the water industry as an example of the use of a large scale and sophisticated SCADA system to provide date collection and control links over a large area. Concludes that the versatility of radio telemetry coupled with its cost‐effectiveness means that this technology can help to expand and improve communications in an increasing number of industries.
