Projecting the DECT network
Preliminary identification of the positions of the base stations
Now plan the positions of the base stations. Take the following into consideration:
u
The information you have collected regarding the requirements for the telephone net-
work
u
Your synchronisation planning
u
The technical conditions for the wireless DECT.
First create a plan in which you then enter the locations of the base stations. You can use
existing building and supply plans, if applicable. For very large buildings, you may be able
to work with partial floor plans and then merge the results of the measurements into the
evaluation.
Creating a planning drawing
Create a planning drawing from the information you have collected in the preliminary
examination of the location. Enter building dimensions, hotspot areas and any sources of
interference already identified.
Examples:
u
The numbers in the rooms reflect the required number of DECT telephones.
u
Areas with high-density traffic are marked as hotspots (HS).
u
The walls marked in bold are assumed to have a high absorption effect, or reflections
can be expected.
u
The dotted lines on the two outer walls indicate tinted windows (coated with metal
film).
u
The stairwell should be covered by DECT wireless transmission. There is a lift here.
