Information is transmitted on mesh networks via electromagnetic waves.

Other wireless (communication) systems can also emit electromagnetic waves and interfere with the Thread radio signal.

Typical systems that may cause interference are:

  • WLAN access points or repeaters
  • Computers or mobile phones with active WLAN or Bluetooth connection
  • Other wireless networks (e.g., Zigbee networks, smart door locks, etc.)
  • Mobile network antennas or repeaters
  • Microwaves
  • Fridges

The following chapters describe potential interference and how to minimize it.
