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 consistent
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.

Ascertaining customer requirements

Since the aim of Ascotel DECT systems is to cover all kinds of different mobility
requirements in a non-standardized environment, we need to determine and
record precisely what sort of requirements the customer has in mind. Records avoid
misunderstandings 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
future?
• Subscribers: How many handsets are required? What sort of phoning pattern do
users have? Recommendation: Allocate in user groups.
• Traffic density: How are the handsets distributed throughout the premises and
which users are where?
• Dynamics: How many handsets 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.
