Introduction
Installation Manual
INDeX CSLC
The site survey is the most crucial part of any DECT installation. It is the
stage at which future success or failure of the installation will probably
occur.
Most issues of customer satisfaction will stem from the site survey and the
resultant positioning of the base stations
From the customer's point of view, two keys factors must be assessed:
– The area of coverage required:
– The number of simultaneous users within different areas:
Each base station can support 4 simultaneous calls. There is no problem
with having more than one base station in the same area.
During the site survey, you will be attempting to determine two factors to achieve the
customers requirements:
– The number of base stations required
– Their best positioning.
To fulfil this you need to obtain the following details:
– Building Measurements:
Accurate building plans are an essential aid to both the site survey and also
for later fault analysis
– Signal Strength: (RSSI - Radio Signal Strength Indication)
From potential base station positions, what is the range of the base station
signal at sufficient signal strength for reliable operation
– Speech Quality: (Q52)
Interference, weak signals and reflected signals lead to errors in the digital
voice signal that cannot be corrected. From potential base station position,
what is the range before the bit error rate becomes unacceptable
