Ra-02 is a wireless transmission module based on SEMTECH's SX1278 wireless transceiver.
It adopts advanced LoRa spread spectrum technology, with a communication distance of 10,000 meters.
It has strong ability of anti-jamming and has the function of air wake-up Consumption.
The SX1278 RF module is mainly used for long-range spread spectrum communication, and it can resist
Minimize current consumption.
The SX1278 has a high sensitivity of -148 dBm with a power output of +20 dBm, and a long
transmission distance and high reliability.
At the same time, compared with the traditional modulation technology, LoRa ™ modulation technology
has obvious advantages in anti-blocking and selection, which solves the problem that the traditional
design scheme can not consider the distance, interference and power consumption at the same time.
It can be covering thousands of people in the district environment, particularly suitable for meter reading,
smart home, burglar alarm equipment.
