The LoRa™ RF Transceiver Module features the Semtech SX1272 transceiver chip which uses a variation of Chirp Spread Spectrum coding called LoRa, to improve receiver sensitivity and hence achieve extended range. The module can also use OOK and FSK modulation schemes to maintain compatibility with other standards such as IEEE 802.15.4 and wMBUS. LoRa features increased interference immunity over conventional FSK providing an enhanced coexistence capability in crowded channels.
