LoRaWAN® Gateways: Radio Coexistence Issues and Solutions

This white paper details the phenomena which could cause desensitization of LoRaWAN gateways because of the co-located transmitters, such as:

  • Out-of-band blocking
  • In-band blocking
  • Third-order intermodulation
  • Generation of out-of-band noise (spurious emissions)

The paper also provides some recommendations to avoid desensitization by using:

  • Radio frequency (RF) filters by design – embedded in the gateway
  • External cavity filters, for specific harsh environments
  • Installation recommendations to minimize interference
