Smart Modems for Robust Wireless Data Transmission Over ISM Bands

Raveon’s supplies Smart Modems for flexible ISM-band transceivers with a myriad of options and features.

  1. Reliable and secure Data with Forward Error Correction (FEC) , bit chipping, and AES data encryption.
  2. Not just several hundred meters, but many miles of communications. 100sq miles in open area.
  3. It is a Versatile Transceiver thanks to dozens of features and configuration settings.
  4. These radios have proven performance, reliability, and quality that our customers expect and have come to know in all of our products.

Various ISM band models have been developed to address different applications. A summary the models are given below. Brochures and manuals are available for download that include detailed specifications. Please give us a call to discuss any of these radios.

The ISM band (Industrial, Scientific and Medical band) is part of the radio spectrum that can be used for any purpose without a license.  In the U.S., it is the 902-928 MHz, 2.4 GHz and 5.7-5.8 GHz bands were initially used for machines that emitted radio frequencies, such as RF welders, industrial heaters and microwave ovens, but not for radio communications.

Raveon’s ISM band radios utilize 902-928 MHz for ultra-long range data communications. 900MHz is much longer ranage band than 2.4GHz and above.

LoRa Technology Description

These Raveon ISM band Daisy Radio Modems utilize a technology invented in France called “LoRa“.  The LoRa Long Range wireless technology is a synergy with Raveon’s other long range wireless data technology, making our Daisy Radio modems work outstanding.  AN205(LoRa_Range)     AN205 describes how LoRa technology is able to help achieve outstanding long-range communications using low-power radios and low RF transmit power.

Raveon’s LoRa radio modem can communication 5-10 times further than ISM band radios built by other companies.  The RV-M50 is and OEM module you can utilize in your products.  The RV-M22 is a LoRa radio modem in the Tech Series enclosure with a myriad of IO options and features.  For LoRa GPS tracking, order the GPS tracking option on any Raveon product.

RV-M50 Daisy Radio

Raveon’s RV-M50 Daisy Radios are our smallest solution daisy chaining all your large scale operations using the license-free ISM band radio channels. This radio is perfect for tracking any number of items over as many locations as you can imagine, making it perfect for you to connect to the internet of things. The Daisy radio is our smallest model yet, making it perfect for daisy chaining your system together across any and all locations. It also integrates flawlessly with your current Raveon M7, or M8 systems, so using it to improve your current solutions or expand operations is quick and easy.

Daisy Radio modules can be incorporated into your products, giving them miles of wireless communication capability.  The Daisy Radio modules use the same UWARC universal wireless interface, so you can design all Daisy Radio modems or our M8 series radios into your products, and just plug in the one you actually want to use.

The Daisy Radio modules are available in our M22 Tech Series enclosures.  The M22 enclosures have a myriad of IO options and features.

The RV-M5 Daisy Radios utilize LoRa communication technology.  The work for data communications or GPS tracking.  Raveon’s Pier-to-Pier mode uses the LoRa protocol to directly communicate between radio to radio, with no need for a “Base Station”.  Simple pier-to-pier data communications is perfect for  daisy-chaining your network. Daisy Radios can pass along data over many miles, with very low power consumption, low RF power, and small antennas.  An their low cost high performance help make you systems more economical.

Daisy Tech Series

The ISM band Daisy Modems are used within the  M22 Tech Series enclosure. The Tech Series is designed to be universal for use with any of our modems, and works especially well with the Daisy systems. The Tech Series unique design allows for interchangeable front I/O panels, so you can connect to your system in a myriad of differing ways. One other new feature is our more rugged power connector, designed to stay connected through even more extreme conditions. IO options are RS-232, RS-485, RS-422, USB, GPIO, and Flexible IO.

General Purpose Tracker using LoRa

Raveon utilizes our ISM band Daisy Radio in a miniature enclosure to create a general purpose tracker.

The RV-V50 Miniature Tracker is a small, very low-power GPS/GLONASS transponder for use in the license-free ISM or cellular bands. Having the longest communication range in its class, it can locate and monitor assets such as automobiles, trucks, racers, rental equipment and more. Its built-in rechargeable battery has extremely long battery life.
