5. Иштөө принциптери
The E32-170T30D module utilizes LoRa (Long Range) spread spectrum technology, which offers significant advantages over traditional FSK (Frequency Shift Keying) modulation, particularly in terms of communication range and interference immunity.
5.1-сүрөт: Comparison illustrating LoRa spread spectrum communication's superior anti-interference performance compared to FSK.
LoRa's spread spectrum technique encodes data across a wider frequency band, making it more resilient to noise and interference. This allows for longer communication distances and improved reliability in challenging environments.
The module's operation at 170MHz contributes to its strong penetration and diffraction abilities. Lower frequencies generally have longer wavelengths, which enables signals to better penetrate obstacles and diffract around them, extending coverage in non-line-of-sight conditions.
