What is the LoRaWAN EU868 Mhz band?

LoRa is a wireless communication technology developed by Semtech in the United States and is widely used in local area networks. This technology can operate on different frequency bands, including 433, 868, 915 MHz, etc. These frequency bands are global free frequency bands and can be used for LoRa communication.

Among them, 868MHz is the European ISM (Industrial, Scientific and Medical) frequency band, which is particularly commonly used for LoRa communication. This frequency band is characterized by low transmission power and is not easy to interfere with other devices, so it can achieve long-distance communication, up to several kilometers outdoors. This makes LoRa widely used in smart homes, the Internet of Things, and urban automation.

In addition, the 868MHz frequency band also has the characteristics of strong penetration and good anti-interference ability. In this frequency band, multiple channels can be accommodated, allowing multiple devices to communicate simultaneously without interfering with each other.

The LoRa EU868 frequency band is the main LoRaWAN frequency band in Europe. Its operating frequency is 868 MHz and is suitable for most European countries. ‌This frequency band is part of the European standard, and together with standards in other regions such as the US standard (‌US915)‌, ‌Chinese standard (‌CN779, ‌CN470)‌, etc., it constitutes the parameter standards of LoRaWAN in different regions. ‌LoRa wireless modulation technology, ‌is basically based on CSS (‌ChirpSpread Spectrum)‌ modulation, ‌using different spreading factors to provide different data rates, ‌enabling LoRaWAN devices to communicate over low power and long distances. ‌In different regions, the frequency bands used by LoRaWAN are different, ‌which is to adapt to the radio frequency planning and communication needs of each region.
