LoRa frequencies
INTERNET OF THINGS7
ISM spectrum in unlicensed bands• In Europe LoRa uses unlicensed
frequency spectrum in 868 MHz band
• Power restrictions apply
• Duty cycle restriction per band
• LoRaWAN defines four standard
frequencies
• 3x for device to contact network
• 1x for downlink with higher power
• Now LoRaWAN supports eight
frequencies (next generation 16 freqs)
Band Frequency Duty cycle Power
F 863.0-865.0 0.1% 14 dBm
G 865.0-868.6 1.0% 14 dBm

Core network
Core network
KPN’s LoRa network consists out of 1000+ LoRa gateways across the Netherlands
Via KPN’s fiber optic network all LoRa data is transported to the datacenter in which the LoRa controller determines which messages to forward.
Data is pushed to the customer application via API.
The KPN core network exists in two geographical different datacenters. All customer data is being forwarded to customer application servers.
