Long Range RF Communications

Thursday 22 April, 2021

Introducing the new CCS Long Range RF Development Kit. LoRa® is low-power wide-area network protocol that can be used to periodically communicate sensor data. LoRa® uses a proprietary spread spectrum modulation that is similar to and a derivative of Chirp Spread Spectrum (CSS) modulation. This allows for long-range transmission, up to 9 miles, with low power consumption. This makes it ideal for battery applications that only needs to periodically transmit sensor data.

The CCS Long Range RF Development Kit comes with two development boards with Microchip's RN2903 modules. The RN2903 modules are designed to communicate using LoRa® modulation using the US frequency band. This is everything needed to develop a LoRa® peer-to-peer (P2P) implementation. The development kit's exercise manual has several exercises for setting up testing different types of LoRa® P2P networks using the provided RN2903 and LoRa® P2P drivers.

Additionally, the development kit can be used the to develop code to communicate on a LoRaWAN®network. LoRaWAN® is a upper level network protocol, developed by the LoRa® Alliance, that uses LoRa® modulation for creating a cloud-based network. In LoRaWAN® networks end-devices periodically send messages to a gateway, which forwards it to a network server which in turn forwards the message to an application server. Any response for the end-device is then forward back in the reverse order. The development kit can be used to develop and test end-devices for a LoRaWAN® implementation, using the provided RN2903 and LoRaWAN® driver. Testing the LoRaWAN® end-device will require at minimum an external LoRaWAN® gateway, not provided with the Long Range RF Development Kit.

LoRaWAN® is a mark used under license from the LoRa Alliance®. Use of the LoRa Alliance® and LoRa Alliance® Member marks is pursuant to license from the LoRa Alliance®.
