LoRa is a low-power LAN wireless standard developed by semtech. Operating frequency :ISM band includes 433MHz, 868MHz, 915MHz, etc. Low power long distance running and high power long distance running is more difficult. LoRa is a long-range radio, it is characterized by the same power consumption, than other wireless transmission distance, to achieve the unity of low power and long distance.

2.The relationship between Lora antenna length and transmission distance?

In Lora communication system, antenna is an important part of information transmission. The length of the antenna directly affects the radiation effect and receiving sensitivity of the signal, and then affects the transmission distance. In general, the longer the antenna length, the longer the transmission distance. This is because longer antennas can produce a stronger signal, helping to overcome attenuation and interference in the transmission path.

However, there are some limitations to antenna length. First, the frequency band used in the Lora system determines the optimal length range for the antenna. Second, too long an antenna may cause the beam of the signal to narrow, thus limiting the transmission distance. Therefore, when designing Lora system, the balance between antenna length and transmission distance should be considered comprehensively.
