On-Site Measuring; Optimum Positioning Of The Dect Base Station - Aastra Messkoffer Bedienungsanleitung

Measurement/Planning

On-site measuring

As soon as the concrete locations for the base stations have been planned, it is recommended to
confirm the circumstances in keeping with the plan using on-site measurements.
Notes
• Installation site for the test base station: To carry out the measurements do not place the base sta-
tion 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 objective 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 verti-
cal.
• The measurements provide a reliable idea of the equipment required and the locations for the
base stations.
• 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 areas where coverage is not optimum.

Optimum Positioning of the DECT Base Station

The location of the DECT base station 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
Notes
Please note that base stations must be spaced out at intervals of approx. 2.50 m horizontally and 1
m vertically. An ideal location for installing a transmitter is a height of between 2 m and 2.50 m (for
room heights between 2.50 and 3 m; for higher rooms, the ideal installation height increases accord-
ingly) while maintaining a minimum distance of 0.50 m from the ceiling. An installation height of
less than 1.50 m is not recommended.
Installation inside a dropped ceiling, cabinets or other enclosed furnishings is not recommended as
this considerably impairs the radio hop and results in the need for more transmitters.
If aesthetic considerations prevail, this must be compensated by a larger number of base stations,
provided this is not rendered impossible by metallic ceiling structures.
