Planning Aastra 400 DECT systems as of R1.0
syd-0457/1.0 – R1.0 – 10.2012
5. 3 On-site measuring
As soon as the concrete locations for the radio units have been planned, it is recom-
mended to confirm the circumstances in keeping with the plan using on-site meas-
urements.
A detailed description on how to use the test equipment can be found in "DECT
Measuring Device ME-8 (test kit)", page 47.
Remarks:
• Installation site for the test radio unit: To carry out the measurements do not
place the test radio unit on the ground / floor but position it in the location in
which it is to be installed later.
• Measurements must be meticulously carried out (no compromises). The objec-
tive is optimum radio coverage.
• Documentation: It is advisable to keep a test log so results can be reproduced
later. Record the values measured as well as the supply range on the ground
plan, horizontal and vertical.
• The measurements provide a reliable idea of the equipment required and the lo-
cations for the radio units.
• Co-operation with the customer: As soon as you are able to make sufficiently
binding statements about "problem areas", you should involve the customer for
clarification purposes. It is imperative that the customer be informed of any ar-
eas where coverage is not optimum.
5. 3. 1 Optimum positioning of the DECT radio unit
The location of the DECT radio unit is determined by a number of different factors:
• Optimum radio coverage of the environment
• Conditions inside the building
• Installation possibilities
• Presence of supply leads and socket outlets
• Aesthetic aspects and wishes on the part of the customer
• Outside the buildings: weather protection (rain, sun), vandal-proof
