Long Range RF for Large SCADA Systems:

SCADA stands for Supervisory Control and Data Acquisition. The Data Radios from Raveon Technologies make ideal wireless modems for SCADA gateways and Remote Terminal Units (RTUs) in SCADA and telemetry systems.

Wireless Connection to SCADA Slaves Long Range Many Miles

Tech Series SCADA Telemetry Radio Modem The Tech Series versions have GPIO and FIO options to enable these Tech Series products to be complete SCADA RTUs, with many different input and output pins and features. This Application Brief describes the general requirements for a wireless SCADA system to communicate with thousands or millions of remote devices. Many telemetry and SCADA systems run on private networks or connect things to the Internet. Raveon’s wireless modems are excellent devices to connect your things to Private Networks or the Internet.

Wireless SCADA: A device or sensor is monitored by a Master Controller. The user may have something as simple as an LED indicator, or as complex as a computer server for the operator. Often this remote device is a Remote Terminal Unit (RTU) or Programmable Logic Controller (PLC). Each RTU has a device ID to identify which RTU to communicate with.
Typical SCADA System
When the distance between the Master Controller and the Slave being monitored is not trivial, a wireless link between the two sites becomes a logical means of connecting them. The RTU monitors the digital and analog parameters in the field, and when the Master queries the Slave, the Slave transmits data to the Master using a SCADA protocol.

Long Range RF Communications:

Long Range RF Data Communications is done in many different ways. This document explains the Pros and Cons of variations in wireless data communications. Communication Range depends on Frequency, baud rate, and TX power
Range depends on Frequency baud rate TX Power
The Science of RF Communications
  • To send data bits long range
    • -Transmit each bit of data with energy. Receiver looks for data and recovers the energy
  • RF energy drops over distance:
      -20 * log(distance)
  • RF energy received comes in via an antenna
    • -Tall antennas (Low Frequency) are bigger and better
  • Sensitive receivers pick up weak signals.
    • -3dB more sensitive is as good as 2X TX power
    • -10dB more sensitive is like 10X more power
  • The longer the bit, the more energy it has
  • Link Margin = 36.6 + 20 * log(D) + 20 * log(F)
What Affects Communication Range?
All things listed here are the main things that affect communication range:
Transmit power
Receiver sensitivity
Antenna gains and antenna heights.
Frequency of the system
The energy per bit (data rate)
Modulation Methods
Baud Rate
Local interference
Topography/Terrain
In-Band Noise filtering
