As reported from their website, seems like a great upgrade for the telemetry radio, maybe to also carry RC control, and depending on bandwidth  maybe using it also for a digital video feed. 

It is on indiegogo

As listed on their site:

XRange: Extreme Long Range Wireless Module based on sx1272 LoRa transceiver for 868 or 915 Mhz (will be available in Q4 2014)

XRange  (sx1272 based ) is extreme long range RF module.It can achieve over 12km(7miles) wireless communication. XRange combines a Cortex-M3 controller with the sx1272 LoRa transceiver.
Xrange-sx1272

What is XRange?

It is a wireless electronics development platform that provides extreme long range spread spectrum communication and has over 12km (7 miles) of usable range.

XRange is based on the SX1272 LoRa™ long range modem, low-power ARM micro-controller and powerful switching power supply.

What can you do with XRange?

  1. Connections in warehouses where data cables and other wiring is difficult or impractical.
  2. Lighting, temperature and other building controls.
  3. Battery-powered data loggers, weather stations, and data logger/controllers.
  4. Solar panels management and monitoring.
  5. Data communication for the Internet of Things.
  6. Remote controlled irrigation systems.
  7. Point-of-sale systems.
  8. Security applications.

Why You should choose the XRange?

  1. It has extreme long range.
  2. It has ability to communicated through walls and other obstructions.
  3. It is low power.
  4. It is low cost.
  5. You can implement many wireless projects with little effort.

  • 100mw for 15Km..looks like promising for the who wants fly over 100km if rf output boosted to 1watt..

  • @Tearig: The RFD900's: http://rfdesign.com.au/index.php/rfd900

  • What antennas were used during that 15k test ?

  • Zouyu, I am after the same thing, differnt application but the same consistent connection needed... Looking forward to testing them

  • Matt what units are you speaking?

  • Considering that the RF Designs telemetry MODEMS support 40km range out of the box -- and are 3DR compatible -- I'm wondering what added value this offers.

  • 868 MHz is either 10% duty cycle or LBT (and AFA). I think 868 MHz is a much better frequency because 433 MHz is pretty crowded - everything from garage door remotes to police radios sits near 433 MHz.

  • Moderator

    Yes won't be much use in South Africa either. Buyer beware!

  • Note that 868 MHz is regulated to hell in Europe - 10% duty cycle over an hour effectively cuts your max. 300 kbps data rate to 30 kbps average, making it useless for any kind of video.

  • I have two questions.How much about your one board and its whether consist a net . I want to use it to consist a net for communicate in voice.
