Optimum Positioning Of The Dect Base Station - Mitel SIP-DECT Site Survey Kit User Manual

• It is important to ensure sufficiently large overlap areas between neighbouring coverage
ranges. The signal should not be so weak that it prevents handover to the next base station.
It is necessary to find a solution between a large number of radio units and a reasonable
coverage of the premises.
• Radio range (guidelines)
- up to 30 m in buildings
- up to 300 m outdoors
• Observe the minimum distance between base stations.
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 station 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
vertical.
• 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 several 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 accordingly) 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 impairs the radio hop considerably and results in the need for more transmitters.
