This page is about understanding the LoRa RF modulation format.

LoRa is an abbreviation of Long Range, meaning it is an radio modulation format that gives longer range than straight FSK modulation. This is achieved by a combination of methods: it uses a spread spectrum technique called Chirp Spread Spectrum (CSS) and it uses forward error coding (in combination with whitening and interleaving).

To transmit or receive LoRa signals, you need to buy hardware that supports this modulation format.

The goal of this project is to collect more detailed information on the LoRa modulation and packet format. A concrete result could be that it becomes possible to use a LoRa transmitter in an amateur high-altitude balloon and allow reception of the LoRa signal using an inexpensive rtl-sdr software-defined-radio in combination with dl-fldigi software.
