Introduction
This guide describes the procedures required for installing the Samsung DECT 500
and 1500 systems with Base Stations, Repeaters and handsets. Before installing the
hardware, a careful site survey must be carried out to determine the exact requirements of the site and the optimum locations for installing equipment.
The site survey and installation phase starts by surveying the site with the Site Survey kit and marking your findings on a plan of the site; it ends when the system has
been running for one or two weeks.
The procedure for the site survey and installation phase is summarised below.
1. Site survey by an accredited DECT engineer.
2. Install the Base Stations (and Repeaters if required) for optimum coverage.
3. Evaluate the site survey. If necessary, install additional Base Stations / Repeaters, or move existing Base Stations / Repeaters.
4. Register handsets.
Part 1 describes the site survey and provides a detailed overview of the various
components of your DECT system, including how Base Stations and Repeaters
should be positioned to provide optimum performance.
Part 2 provides information on procedures to install and configure the hardware
components for each system (CCFP, Base Stations, handsets etc.) and how to install
Repeaters.
Installation and configuration of the DECT 1500 system requires the use of the supplied administration program running on a PC connected to the system. This is optional for a DECT 500 system.
Some Terminology
Throughout this guide, you will find the following terms used:
CCFP=Central Control Fixed Part (the system “central processing unit”)
RFP=Radio Fixed Parts (Base Stations)
WRFP=Wireless Radio Fixed Parts (Repeaters)
PP=Portable Parts (handsets)
Important: The DECT system is not intended to be a cordless PABX solution. It
is provided as an “add-on” to enhance the current range of Samsung PABXs.

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 central 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 Stations.
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 particular:
• 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, depends on the environmental characteristics of a site.
y The signal 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.

Part 1: Site Survey and Overview of DECT Systems
Environmental Considerations for Users and Buildings
y Carefully track the movement of users to establish movement patterns. The number of
Base Stations required is determined by the number of users and their movements.
y The distance between Base Stations should be at least 3m to avoid interference. Keep the
distance between Base Stations shorter the more frequently users move while in conversation.
y Do not install a Base Statio n where it could spoil architectural features.
y Consider ease of maintenance when installing a Base Station.
Other Considerations
y There should be at least one Base Station with an RSSI (Receive Signal Strength Indicator)
value greater than 65 hex and a “Q” value (bit error rate) greater than 52 at some location
within the service area for DECT users.
y Take into account radio interference caused by objects such as trees, walls and glass. Try
to install in an open environment where masking by objects is minimised. Refer to Table 1
for details.

y
When installing cables for Base Stations, keep them away from high-speed LAN cables and
power cables which can cause electrical interference. Maintain at least 1m distance.
y Avoid installing a Base Station near windows since radio interference between floors of a
building might be more active due to diffraction of radio waves.
y It is recommended that a Base Station should be installed at a distance of 2m from the floor
and 30cm from the ceiling, and cables should come from the ceiling rather than the floor.

Part 1: Site Survey and Overview of DECT Systems
y Take into account interference from adjacent cells when the DECT system is installed in a
multi-storey building (Hot Spot).
y
Take into account the following characteristics of radio waves.
- Body effect:
The RSSI and Q values may differ depending on the location of the handset on the hu-
man body.
- Speed of moving handset:
The RSSI and Q values may fluctuate if a handset moves at speed.
- Line of sight:
Much more consideration is required when a Base Station is to be installed in a wide-
open area.
- Multi-storey deployment:
Characteristics of cells in each storey may differ due to the structure and materials of the
building.
Information Required
y Obtain a map of the site.
y Note the general construction materials used in walls and doors of the building(s), including
window coating and covering, if any. Also note any large metal objects such as equipment,
doors, and fluorescent lamp shades. In general, radio frequency (RF) signals are attenuated to some degree when passing though materials. Some materials, such as metal, attenuate RF signals to a higher degree. (See Table 1, above
y Define the number of handset users and which are the high traffic areas, such as confer-
ence rooms, cafeterias and manufacturing departments.
y Check which positions allow and prohibit Base S tation installation.
y Determine the required coverage areas, such as elevators, stairwells, toilets, outdoor areas
etc.
y Establish the position of the DECT system and available cabling.

Site Survey Procedure
Before you start cell planning, the coverage estimation for the site should be completed and the possible Base Station locations indicated on the site map. Cell planning is done as follows:
1. At a selected Base Station location, set up the survey kit.
2. Place the Base Station near the ceiling or at a height of about 2.5m.
3. Press * 99989 * on the handset.
The handset displays the RSSI and Q values of the Base S tation.
4. Move away from the Base Station and check the RSSI and Q values until they read the minimum (RSSI=65, Q=52). Stop and ma rk this as the border of the cell on the map. Note that:
y When measuring RSSI and Q values, hold the handset close to your body or shield the
aerial with the handset with your hand, pause for 2–3 seconds, take a reading and move
on.
y To avoid confusion, different cell boundaries should be marked with different line patterns,
e.g. dashed line, dotted line, etc. Do not use colours as these may be lost when photocopying.
y For a multi-storey building it must be clear on what floor the Base Station was positioned
and that the result may be several cell contours on different floors.
5. Using the following numbering conventions, name the Base Stations and cells and mark
them on the map.
y xRyy : refers to the identity of the Base Station, where
x is the level (-1 is basement, 0 is ground, 1 is the 1st floor, etc)
R means this is a Base Station
yy is the Base Station position number. This number should be unique.
For example, a Base Station on the 2nd floor and with position number 4 is identified as
2R04.
y xCyy : refers to the identity of the cell, where
x is the level at which the measurement was made (-1 is basement, 0 is ground, 1
is the 1st floor, etc)
C means this is a cell
yy is the position number of the Base Station being measured
For example, if measurement is made on the 2nd floor and the measured Base Station
position number is 4, the identity of the cell is 2C04.
.
6. Repeat steps 1–5 for the remaining planned Base Station positions.
7. At this stage, it may be necessary to move some of the planned Base Station positions or
add new ones to eliminate shadows or optimise cell size. If so, it may also be necessary to
do additional measurements to check that the new Base Station positions do not create
other problems.
5
Part 1: Site Survey and Overview of DECT Systems
Choose the Base Station positions required. This may need to be done in consultation with a
customer engineer. In choosing Base Station positions, the required cabling to the keyphone
system should be considered. Base Station positions must be defined such that later installation problems are minimised.
8. Having completed the above procedures, install the Base Stations in the positions marked
on the map.
Some example cell planning results are shown at the end of this chapter.

Radio Coverage
List areas where radio coverage is not necessary or which are to be excluded from
radio coverage. Also list areas where radio coverage is not feasible or requires specific Base Stations.
Keyphone System
Type and location of keyphone system (e.g. OfficeServ 500).
Reporting Site Survey Results
It is important to make a comprehensive survey report that records site survey results
and provides useful information for the engineer who is to actually install the equipment. The following information should be included in the survey report. (See the
DECT Survey Report Form over the page.)
y A description of the site, explaining whic h buildings and grounds are to be included in the
report. A description of the topography of outdoor areas may be useful.
y A specification of the construction of the buildings and construction materials.
y Customer requirements for:
- the number of handsets
- required coverage
- performance requirements (traffic density, grade of service etc.)
y The location and the type of the keyphone system (e.g. iDCS500, OfficeServ500).

Part 1: Site Survey and Overview of DECT Systems
y Cabling details: a specification of cables already present on the site and a list of new
cabling required, including the distance between the Base Station and IWU card for existing
and new cabling.
y Copies of the maps of the site with the position of Base Stations an d cell boundaries clearly
marked.
y A list of possible configurations to help the customer decide exactly what is req uired.
y A specification of where Base Stations should be placed. This can be marked on the survey
map, but additional information such as height and fixing instructions should be included
where appropriate.
y A specification of the areas that will be covered by the Base Stations and areas that may
cause problems. This can be useful when testing the system. The theoretical maximum
number of overlapping cells is 10, if all time slots and frequencies are used. If not all time
slots and frequencies are used, this value is higher, although this is unlikely to be the case
in practical situations. For a large site where a thorough survey has been impossible, it may
be prudent to add 10–20% more Base Stations to requirements to allow for unforeseen
problems.
