IP DECT 6000 System Installation & Configuration Guide
3 Deploying the IP DECT Server 6000
Before you install the IP DECT Server 6000 solution, it is necessary
to carry out a complete site design – at the minimum on the basis of
environmental drawings (like GA for ships, or floor plans for buildings)
- to determine the exact location of the Server 6000, base stations,
repeaters and the number of handsets required.

Due to the unexpected nature of RF propagation in an indoor environment, an
actual on-site test may need to be carried out before the installation is complete.
While an extensive guide to effective RF coverage planning is beyond
the scope of this manual, the following points should be taken into
consideration when planning the site, prior to base station and repeater
installation:
●
The base station/repeater provides typical RF coverage of up to
50 meters/164 feet in a typical indoor office environment and up to
300 meters/984 feet in an open area (line-of-sight), extending in all
directions from the base station/repeater. The exact coverage range
depends on the building architecture, wall material and surroundings.
●
The wireless solution can support a maximum of 500 handsets and
255 base stations. (See Table 1 in section 2.1).
●
Handset handover: handsets can move between coverage areas of
base stations and repeaters while receiving continuous service and
maintaining conversations in progress. However, for steel container-
like rooms (such as ship cargo rooms) it is not to be expected that
the standard radio antenna base stations will be able to support
handover.
-
For deployment on ships, the radiating cable solution may be used.
● For efficient handover of conversations between base stations,
deploy base stations with wide overlap between them (i.e. plan for
some areas to be covered by more than one base station). Overlaps
are necessary to maintain seamless handover and to establish
synchronization chains. A good example may be a cafeteria during
lunch hour where temporary concentrations of handsets may occur.
The overlap carries the excess call load to adjacent base stations to
provide uninterrupted services to subscribers.
● Typically, installations such as office buildings, hotels and hospitals
should be equipped with base stations/repeaters on several floors to
create uniform and complete RF coverage.
●
Open areas can be covered with a sparse network of base stations.
In such applications, the base stations/repeaters cover an extended
range due to the extended line-of-sight RF propagation capability.
●
Ensure that there is no residential DECT system (home DECT) on
the site.

Recommendations for Base Station / Repeater
Placement
● In large halls, the base station/repeater (wall) should be installed
vertically in the middle of the space below the drop ceiling.
● In corridors, the base station/repeater (wall) should be installed
vertically, preferably at corridor intersections where propagation
patterns follow the corridor patterns. The base station/repeater
should point towards the corridor and preferably at mid-height
between the floor and the actual ceiling. In cases where there are
tall objects in the area, the base station/repeater should be installed
