The LoRa Alliance has defined two frequency bands for the usage of LoRa technology in Europe. These bands are EU433 from 433.05 to 434.79 MHz and EU863 from 863 to 870 MHz.

EU433 (433.05 to 434.79 MHz)

The end devices in EU433 band operate from 433.05 to 434.79 MHz and use a channel data structure to support at least 16 channels.

The first three channels correspond to 433.175, 433.375 and 433.575 MHz and being default the channels; they cannot be modified through the NewChannelReq command. These three channels guarantee a minimal common channel set between end-devices and gateways of all networks. Other channels can be freely distributed across the allowed frequency range on a network per network basis.

The LoRaWAN technology can be used in ETSI EU433 band as long as the radio device EIRP is less than 12.15 dBm and the end-device transmit duty-cycle should be lower than 10%. The center frequency of the channels associated with this band ranges from 433.175 to 434.665 MHz.

The EN300220 ETSI standard offers a maximum transmit duty-cycle up to 10% in the EU433 MHz band. The LoRaWAN requires a 1% transmit duty-cycle lower than the legal limit to avoid network congestion.

EU863-870 (868.1 to 868.5 MHz)

The EU863-870 band can be used in any region where the ISM radio spectrum is defined by the ETSI 307 standard. The end devices in this band will operate from 863 to 870 MHz and use a channel data structure to store the information of at least 16 channels. The channels in this band can be attributed freely by the operator; however the three default channels; 868.10, 868.30, 868.50 are mandatory to be implemented in every EU863 end-device. Other channels can be freely distributed across the allowed frequency range on a network per network basis.
