Base Station Coverage: In Practice

Using the DECT Site Survey Kit
IP Office - Job Aid
In practice, no rules can be given for base station coverage. Coverage is
affected by too many factors that are unique to each site. We can only
guide you as to those things that are likely to affect base station coverage.
Obvious causes of signals problems:
– Metal surfaces.
– Concrete thickness greater than one metre.
Beware of:
– Windows with reflective film or specialised glass:
These produce increased signal reflection and reduced signal pass-
through.
– Wire Meshes and Grills with apertures of less than 4cm:
These block signals as effectively as continuous metal sheet.
– Fire Doors:
These block the signals. In multi-occupancy building such as hotels
the high number of fire-doors may be a problem.
– Stair Wells:
In modern office buildings, stair wells frequently combine concrete
building supports, fire doors and the intervening floor material,
making them a special problem.
– Screened Rooms:
Typically found in offices involved with TV, video and radio
production, but also possible in computer centers.
Opportunities to be aware of:
– In multi-storey buildings, if the building construction allows, a base
station on one floor can also serve the floor above or below.
