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)

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.
