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:


SCADA can also operate on trunked radio system talkgroups, cellular, PCS and other wireless or wire networks.
