Part 1: Site Survey and Overview of
DECT Systems
Preliminaries
The DECT 500 is an entry-level system comprising a single Base Station/Controller
(CCFP) allowing up to eight handsets to be used. The DECT 1500 comprises a cen-
tral control unit (CCFP) supporting up to eight Base Stations and 64 handsets. The
DECT 1500 can also be installed with an expansion board to support up to 16 Base
Stations, or can be configured as two “linked” systems supporting up to 32 Base Sta-
tions.
The site survey defines the locations of Base Stations needed to cover the area of
the site adequately, and the number required for a 1500 system.
During the site survey and before the Base Stations are installed, an estimate of the
expected number of users and the required coverage area should be made. In par-
ticular:
•
How many handsets are expected to be used now and in the future?
•
How many calls are made, and how long is the average call?
•
Is it necessary to have 100% coverage?
Before Starting the Survey
Due to the nature of radio waves, wireless telecommunication, to a large extent, de-
pends on the environmental characteristics of a site.
y
The s
ignal strength of radio waves transmitted from a Base Station should be measured
carefully at several points. The results can then be recorded in the form of contour lines on
the site map.
y
A great deal of time and effort can be saved if simulation devices or measuring devices are
available.
y
The pre-prepared survey kit and a
DECT D-5000 handset can be used to measure the strength
of radio signals.
y
All the test results should be kept safely for effective maintenance of the site.
