LoRa Frequency Bands in China

The LoRa Alliance has specified two frequency bands for LoRa technology in China. These bands are the CN470-510 from 470 to 510 MHz and the CN779-787 from 779 to 787 MHz. The standard frequency range is allotted, as per the FCC guidelines.

Band 1 - CN470-510 (470 to 510 MHz)

In China, the CN470-510 band is the 470 MHz ISM-band which can be used for Civil Metering applications. It is divided into the following channel plans:

The end devices associated with CN470-510 operate in the 470 to 510 MHz band and use a channel data structure to store the information for 96 uplink channels. Each channel data structure corresponds to a particular frequency and a set of data rates usable on this frequency. For all the personalized devices, all the 96 channels should be enabled, including a reset. The LoRaWAN technology can be used in the 470 MHz band, as long as:

• The radio device EIRP (Equivalent Isotropically Radiated Power) is less than 19.15 dBm.
• The transmission should not last more than 5000 ms.

Band 2 - CN779-787 (779 - 787 MHz)

The end devices associated with the CN779-787 band operate from 779.5 to 786.5 MHz band and use a channel data structure to store the information for at least 16 channels. Each channel data structure corresponds to a particular frequency and a set of data rates usable on this frequency. The LoRaWAN can be used in CN779-787 band as long as the EIRP is less than 12.15 dBm and the transmit duty cycle is lower than 1%.
