In our manuals, we specify a maximum Dect range of 50m inside and a maximum of 300m outside buildings.
Depending on the used building materials, but also other factors, the range may actually be less.
Interference from obstacles that dampen radio propagation and thus lead to radio shadows.
Interference caused by reflections that impair call quality (e.g., crackling or noise)
Interference caused by other radio signals, which leads to errors in transmission
Interference due to obstacles
Possible obstacles can be:
Building structures and installations such as reinforced concrete ceilings and walls, stairwells, long corridors with fire doors, risers, and cable ducts.
Metal clad rooms and objects such as cold rooms, computer rooms, metal clad glass surfaces (mirroring), fire walls, refrigerators, electric water heaters (boilers).
Moving metal objects such as elevators, shutters.
Room furnishings such as metal shelving, filing cabinets.
Radio coverage in elevators is usually poor or non-existent
Range loss due to building materials compared to the free radio field:
|Glass, wood untreated||approx. 10%|
|Wood, treated||approx. 25%|
|Plasterboard, Rigips walls||approx 27 - 41%|
|Brick wall, 10 to 12 cm||approx. 44%|
|Brick wall, 24 cm||approx. 60%|
|Gas concrete wall||approx. 78%|
|Wired glass wall||approx. 84%|
|reinforced concrete ceiling||approx. 75 - 87%|
|metal-coated glass||approx. 100%|
What can I do to improve my dect-range?
In many cases it is sufficient to place the base a little differently 30 - 100 cm from the original location. Avoid placing it in front of glass windows or walls that contain vertical pipes.
In larger living areas, the use of a Gigaset Dect repeater can also improve radio coverage.
