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.

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.

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

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

RV-M6 - M6 Narrow Band 2W OEM Radio Modem

The M6 OEM Radio Modem is low-cost rugged single-board 2W VHF/UHF/900MHz narrow-band OEM data radio modem with digital serial interface. Ideal for Automatic Meter Reading (AMR), SCADA and telemetry applications. It is over-the-air compatible with Raveon’s 5-watt M7 and M8 series of data radios.

Product Overview

Long-Range Operation

-Operating in the narrow-band frequency bands, the RV-M6 radio modem works over 10 miles point-to-point and many miles with omni-directional antennas. All RV-M6 modems support store-and-forward repeating for wide-area coverage.

GPS Option

-The optional internal GPS allows the RV-M6 to be a powerful Automatic Vehicle Locating (AVL) system or Time Space Position Information (TSPI) reporting device. Raveon’s TDMA protocol is built in for track thousands of things in real time.

Tech Series I/O Options

-The M6 may be installed in a Raveon M22 Tech Series enclosure with these I/O options. The following interface boards may be attached or changed at any time: RS-232 [ S ], USB [ U ], RS-485 [ T ], RS-422 [ F ], GPIO [ G ], Analog [ A]

High Speed and High Efficiency

-The RV-M6 operates with user-selectable over-the air data rates of 1200 to 19200bps. Its fast-switching radio enables it to send up to 50 transmissions per second.

Wireless SCADA RTU

-When used with the GPIO interface in the Tech Series enclosures, or just using the M6’s TTL IO pins, it implements many SCAD remote terminal unit features.

Flexible Input Voltage

-The RV-M6 is designed to run off of voltage sources such as 7V-30V. For other voltage ranges, contact the factory.

Automatic Meter Reading

-Being small, power efficient, and fast makes the M6 ideal for automatic meter reading. With a communication range of many miles, a network of M6 radios can cover a nation reading and managing a smart grid.

Spectrally Efficient

-In the USA, FCC complaint data radios must be capable of 9600baud in 12.5kHz channel or 19200baud in 25kHz channel. The M6’s 4FSK modes meet all FCC spectral efficiency requirements.

Network Management

-The CPU in the M6 has many features and command implemented in it to make setting up and managing large radio networks very easy. 16 bit IDs, ID masks, packet filtering, and repeating by ID are some powerful features. Ping by ID capability and remote command execution simplify network monitoring and diagnostics.

Very Low Power Consumption

It has very low power consumption, and sleep modes allow it to be active and consume almost no power at all.

Universal 20-Pin Header

The M6 is plug-in compatible with Raveon’s M8, M50, and Z50 giving your design the ability to use cellular, 915MHz ISM LoRa, industrial VHF, UHF, 220MHz, or the M6.
