Lierda LSD4RF-2F717M91 LoRa M2M Module Specifications:
* Working voltage: 2.4~3.6V;
* Working frequency band: 470~510MHz (can be customized);
* Transmit power: 19±1 dBm(max);
* Ultra-high receiving sensitivity: -136±1dBm (@250bps);
* Super far effective communication distance: 5Km@250bps;
* Communication using spread spectrum technology, the same urban and industrial application environment, the performance is better than the RF products using traditional modulation methods (FSK, 2-FSK, 4-FSK, GFSK, PSK, ASK, OOK, etc.), in the harsh In the noise environment (in the vicinity of strong interference sources such as electricity meters, motors, etc., natural shielding environments such as elevator shafts, mines, basements, etc.), the advantages are particularly obvious;
* High confidentiality, using LoRa modulation, which cannot be captured and parsed by traditional wireless devices;
* High concealment, the average power in the band is lower than the noise floor, and the communication can still be normal, and the wireless monitoring device cannot monitor it;
* Fast switching of status through I/O operation;
* It can customize communication parameters according to user's preference and usage environment (such as prioritizing power consumption, prioritizing communication distance, optimizing noise resistance, especially optimizing encryption, etc.);
* High reliability, small size, light weight and low power consumption.
