Hardware preparation and installation
In situations that require broader coverage, for example if you require too many repeaters to
extend the range of coverage or you have too many users, you must use an additional base
station. Bear in mind that each base station requires its own repeaters.
Obvious causes of signal problems
The base station and its repeaters must be no closer than 17 feet (5 meters) from other DECT
base stations and repeaters, including other D100s on the same IP Office.
The repeaters registered to a particular D100 base station must be at least 35 feet (10 meters)
from the base station, and 35 feet (10 meters) from other repeaters. This range limitation is
particularly important in multi-floor deployments.
The following can also cause signal problems:
• Metal surfaces
• Concrete thickness greater than three feet (one meter)
• Windows with reflective film or specialized glass produce increased signal reflection and
reduced signal pass-through.
• Wire meshes and grills with apertures of less than 4cm (1.5 inches) obstruct signals as
effectively as continuous sheet metal.
• Fire doors can block the signal. In multi occupancy buildings, such as hotels, the high
number of fire doors might be a problem.
• Stairwells, such as in modern office buildings, frequently combine concrete building supports,
fire doors, and the intervening floor material. This can be especially problematic.
• Screened rooms, such as those typically found in offices involved with TV, video, and radio
production, can cause signal interference.

Using a floor plan
To obtain the best possible performance, you must install all of the base stations in a location that
provides proper coverage. You should use a floor plan to determine the location for the base
stations. Perform the following steps:
Procedure
1. Draw a floor plan of your environment.
2. Identify all of the people in the environment who will use a D160 handset.
3. Identify the location where you want to install a base station.
Start with one base station and determine the coverage of that base station in step 4, then
include additional base stations, if necessary.
The following image demonstrates the floor plan for a sample company.
