Current wireless communication technologies tend to offer only one of two options: low-power, cheap, but short-range or high-power, long-range, but expensive. A comparison was made against Wi-Fi, SigFox, Zigbee, and LTE-M active radio technologies, which were found to be significantly more expensive ($4 to $6 per unit), and also had much higher power requirements. While all the aforementioned have long-range communication capabilities, their energy and economic requirements made them less ideal for large-scale use in embedded systems.
Hence, the addition of LoRa, a Low-Power Wide-Area-Network (LPWAN) specification, that sends smaller packets at lower power and has a longer range. This adds the required sensitivity to make the backscattering technique operational over greater distances with the addition of a small power source providing 9.25 micro-Watts. The sensitivity was brought down to -149 dBm, had a data rate of 18bps-37.5kbps, and could be powered by a button cell battery, a printed battery, or a small solar cell.
Lora1276-C1 integrates Semtech RF transceiver chip SX1276, which adopts LoRa TM Spread Spectrum modulation frequency hopping technique. The features of long distance and high sensitivity (-139 dBm) make this module perform better than FSK and GFSK module. Multi-signal won't affect each other even in crowd frequency environment; it comes with strong anti-interference performance. This module is 100mW and ultra small size, widely used in AMR,remote industrial control filed.
