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, wireless remote control or telemetry 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.
There are several VHF high band telemetry frequencies for non-federal users:
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
Additional frequencies may be used for SCADA including:
- 72-76 MHz
- 216-220 MHz
- 450-470 MHz Fixed
- 450-470 MHz Low Power
- Hydrological/Meterological Channels in the 169-171 and 406-415 MHz bands which are shared with the federal government.
- Fixed Microwave Services frequencies in the 928-960 MHz and higher bands.
- Other VHF and UHF frequencies in the Industrial/Business Pool and Public Safety Pool may be used on a secondary basis.
- 902-928 MHz, 2.4 GHz and 5.7 GHz low power license free ISM bands.
- Federal government SCADA operations are usually on federal frequencies.
SCADA can also operate on trunked radio system talkgroups, cellular, PCS and other wireless or wire networks.
