SCADA is an acronym which stands for Supervisory Control and Data Acquisition. It may be used for a variety of applications where work processes, voltages, load, alarms, fluid levels, or wireless remote control is required. This control may be one-way or two-way and may have tones or data of varied bandwidth based on the processes being monitored or controlled. A number of control schemes may be used, some proprietary.
SCADA typically takes place the following VHF frequencies:
154.45625 154.46375 154.47125 154.47875 154.48250
173.20375 173.21000 173.23750 173.26250 173.28750 173.31250 173.33750 173.36250 173.39000 173.39625
Frequencies between 450 and 470 MHz can be used on a secondary basis. SCADA operations may also take place on 72 to 76 MHz, and on frequencies regulated by Part 101, the Fixed Microwave Services rules. Note that this rule title is a misnomer. Part 101 also covers point to point frequencies which lie outside of what is generally accepted as microwave spectrum.
SCADA operations which are limited to meteorolgy, flood gauges, stream flow gauges, etc. take place on the Hydrological/Meterological Channels.
