19. Interference factors for DECT
Planning and measuring required!
Loss of range through building materials in comparison with a free wireless field:
Material Loss of range
Glass, wood, untreated Approx. 10%
Wood, treated Approx. 25%
Plasterboard Approx. 27–41%
Brick wall, 10 to 12 cm Approx. 44%
Brick wall, 24 cm Approx. 60%
Aerated concrete wall Approx. 78%
Wired glass wall Approx. 84%
Reinforced concrete ceiling Approx. 75–87%
Metal-coated glass Approx. 75–87%

22. Measuring the synchronisation field strength
• Signal strength between base stations (synchronisation measurement).
• Frame quality between basestations
• No active connection

23. Measuring the wireless coverage
• Signal strength between the base stations and defined measurement
points
• With active connection
