Figure 11: DECT range calculation chart
The range in the air is 80 m from the DAP, for optimal communication quality. The result of this
coverage calculation is a map with possible DAP positions indicated.
Use the following DAP ranges as a rough guide for planning the DAP positions:
• In the line of sights the DAP has a range of approximately 80 m.
• In halls the DAP has a range less than 80 m.
• In buildings the DAP has a range of 15 to 40 m. This is based on the assumption that
walls are made of light brick, plasterboard or wallboard with metal frames. Normal
electrical wiring, central heating pipes, office furniture and desktop computer equipment
have no significant effect. Ensure that you consider the signal shadowing effect of
stairways, lift shafts, and shielded rooms.
The following items cause shadowing of the radio signal:
• Thick walls, especially cavity walls and reinforced concrete walls.
• Windows or glass in doors with steel wire reinforcement or metallic reflection film.
• Steel doors, partitions, or walls.
