Mine Radio Underground Communications: Leaky Feeder Radio SystemRaveon’s data radio products are well-suited for wireless process control, wireless SCADA and wireless telemetry applications. With the fastest Transmit / Receive turn around time in the VHF/UHF radio modem business, your polled telemetry system will operate fast and efficient.See this example of a pipeline-monitor using Raveon’s data radio.

Raveon’s Wireless Telemetry Product Features

  • RS232, RS422, and RS485 serial interfaces.
  • Easy to use with built-in smart radio modem. Data In = Data Out.
  • Works with MODBUS, DNP, and most serial SCADA protocols.
  • 1/2-5 watts of RF output in the 450-480MHz. (other bands available)
  • Range of 5-50 miles.
  • Ultra-fast T-R switching time of 3mS.
  • Store-and-forward repeater capability.
  • Exceeding all FCC part 22 and 90 requirements.
  • Remote “Ping” capability.
  • Low Latency Streaming.

Wireless SCADA is required in applications when communications with wires to a remote site is prohibitively expensive or it is too time-consuming to construct. Wireless SCADA systems are easy to install and communicate to hundreds of devices with very little wire.  In some types of industry such as Oil & Gas or Water & Wastewater, wireless SCADA is often the only solution for remote sites.

Wireless SCADA systems can be built on a private radio network, cellular, or satellite. system. Each of these has its own unique set of characteristics shown below.

Raveon has many products for Private Radio Networks, and License Free ISM bands.  Private networks are reliable, secure, and low cost.  The RV-M7 and RV-M21 data radio modems can be used to crate a 100+ square mile SCADA system.

Wireless data modems

Ideal for SCADA and Telemetry applications, the M7 series of products features: 1/2-5 watts of RF output in the 450-480MHz (other bands available), range of 5-50 miles, ultra-fast T-R switching time of 3mS, store-and-forward repeater capability, remote “Ping” capability, voltage, temperature, and current monitoring, and RS232/422/485 interfaces available. Perfect for wireless SCADA, remote control, telemetry, mobile-data, and AVL applications.

More Info…

If you want to monitor voltages, monitor switches, output DC power:

Utilize the Tech Series radio modems with RTU features built into them.  No need to buy an RTU.

The Tech Series modem with GPIO interface (See above) works on private wireless networks in VHF, UHF or ISM bands. The GPIO interface can be used to measure voltages, monitor switches, turn lights on or off, turn relays on or off, or measure temperatures. Also built into it is an accelerator to measure the angle or motion of the product. Use our local or over-air commands to manage it, or utilize MODBUS commands.
