WebSemtech’s LoRa Chirp Spread Spectrum (CSS) technology offers a low-cost and low-power, yet robust, DSSS alternative that does not require a highly-accurate reference clock. In LoRa modulation, the spreading of the signal’s spectrum is achieved by generating a chirp signal that continuously varies in frequency, as is depicted in Figure 5.
