With SEMTECH's patented LoRaTM modulation technology, the SX1278 has a high sensitivity of over -148dBm, +18dBm power output, long transmission distance and high reliability. At the same time, compared with the traditional modulation technology, LoRaTM modulation technology has obvious advantages in anti-blocking and selection, and solves the problem that the traditional design scheme can not take into consideration the distance, anti-interference and power consumption at the same time.
