Planning Aastra 400 DECT systems as of R1.0
syd-0457/1.0 – R1.0 – 10.2012
5 Planning
In practice a regulated procedure for planning has proved sensible and, above all,
efficient. A considerable increase in efficiency can be achieved through the consist-
ent use of the aids available.
In the following, the planning procedure is described in the form of a "checklist":
1. Ascertain customer requirements.
2. Roughly determine the locations for the radio units.
3. Measure out the DECT system in situ.
4. Install and re-measure the system.
5. 1 Ascertaining customer requirements
Since the aim of DECT systems is to cover all kinds of different mobility require-
ments in a non-standardized environment, we need to determine and record pre-
cisely what sort of requirements the customer has in mind. Records avoid misun-
derstandings and can be used as a working paper (e.g. project progress report) or
as specifications to be confirmed by the customer.
Important questions:
• Situation: Where are the calls to be made from – outdoors / indoors?
• Premises: What surface area and what height or depth (storeys, basement floors)
form part of the supply range? Recommendation: Ask for a floor plan.
• Building structure: What sort of materials and types of construction are the
buildings made of? What sort of structural changes are planned for the near fu-
ture?
• Users: How many cordless phones are required? What sort of phoning pattern
do users have? Recommendation: Allocate in user groups.
• Traffic density: How are the cordless phones distributed throughout the
premises and which users are where?
• Dynamics: How many cordless phones are expected where and at what times of
the day? Recommendation: Take account of special infrastructure areas such as:
Canteen: 9:00…10:00, meeting rooms.
