Sources of interference

The following sources of interference can adversely affect the smart home network:

• Structural obstacles (signal attenuation and reflection)
• Solid masonry (stone and reinforced concrete walls as well as ceilings)
• Metal objects and metal housings (e.g. large domestic appliances)
• Water-bearing pipes or floor heating systems (water absorbs high-frequency signals)
• Active radio frequency interferences (interchannel interference to 2.4 GHz)
• Other wireless devices (e.g. DECT wireless telephones, baby monitors, Bluetooth speakers)
• Nearby wireless local area or Zigbee networks on the same or overlapping radio channels
• Electromagnetic and magnetic fields of interference
• Electromagnetic fields due to power lines or large electric motors
• Powerful magnets (e.g. neodymium magnets) in immediate proximity to the product
