Эта LoRa скорее рекламный ход. Тестировали и свои платы и готовые отладочники. В итоге применили CC1200. У TI на ютуб есть ролик где сравнивают лору с сс12 , там сразу все становится ясно.
Вот что на техасе пишут:
The 168 dBm link budget comes from the SX datasheet number of -148 dBm sensitivity. This sensitivity is at 18 bps (yes, 18 bits per second), which is not a usable rate for any application, just a showcase number for the datasheet frontpage. For a rate of 4.8 kbps, a solution based on TI Narrowband technology will give more range and a more robust link than a link using LoRa.
The modulation format in LoRa is Chirp Spread Spectrum (CSS), a technology invented in the 1930's. CSS is widely used in radar and ranging applications, but not in communications systems. The main reason CSS is not used in communication systems is the very weak co-existence performance, i.e. the ability to reliably operate in presence of interference. LoRa spread the signal information over a wide bandwidth (500 kHz), but will be jammed by any other system operating in this bandwidth (check out the co-channel rejection on page 21 in the SX1276 datasheet.....).
