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 require-
ments of the site and the optimum locations for installing equipment.
The site survey and installation phase starts by surveying the site with the Site Sur-
vey 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 / Re-
peaters, 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 sup-
plied administration program running on a PC connected to the system. This is op-
tional 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 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.
yThe 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.
yA great deal of time and effort can be saved if simulation devices or measuring devices are
available.
yThe pre-prepared survey kit and a DECT D-5000 handset can be used to measure the strength
of radio signals.
yAll the test results should be kept safely for effective maintenance of the site.

Environmental Considerations for Users and Buildings
yCarefully 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.
yThe 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 conversa-
tion.
yDo not install a Base Station where it could spoil architectural features.
yConsider ease of maintenance when installing a Base Station.
Other Considerations
yThere 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.
yTake 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.

yWhen 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.
yAvoid installing a Base Station near windows since radio interference between floors of a
building might be more active due to diffraction of radio waves.
yIt 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

yTake into account interference from adjacent cells when the DECT system is installed in a
multi-storey building (Hot Spot).
yTake 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
yObtain a map of the site.
yNote 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 attenu-
ated to some degree when passing though materials. Some materials, such as metal, at-
tenuate RF signals to a higher degree. (See Table 1, above.)
yDefine the number of handset users and which are the high traffic areas, such as confer-
ence rooms, cafeterias and manufacturing departments.
yCheck which positions allow and prohibit Base Station installation.
yDetermine the required coverage areas, such as elevators, stairwells, toilets, outdoor areas
etc.
yEstablish the position of the DECT system and available cabling.
Tools Needed for Site Survey

Site Survey Procedure
Before you start cell planning, the coverage estimation for the site should be com-
pleted and the possible Base Station locations indicated on the site map. Cell plan-
ning 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 Station.
4. Move away from the Base Station and check the RSSI and Q values until they read the mini-
mum (RSSI=65, Q=52). Stop and mark this as the border of the cell on the map. Note that:
yWhen 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.
yTo 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 photo-
copying.
yFor 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.
yxRyy : 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.
yxCyy : 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.

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 installa-
tion 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.

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 equip-
ment. The following information should be included in the survey report. (See the
DECT Survey Report Form over the page.)
yA description of the site, explaining which buildings and grounds are to be included in the
report. A description of the topography of outdoor areas may be useful.
yA specification of the construction of the buildings and construction materials.
yCustomer requirements for:
- the number of handsets
- required coverage
- performance requirements (traffic density, grade of service etc.)
yThe location and the type of the keyphone system (e.g. iDCS500, OfficeServ500).

yCabling 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.
yCopies of the maps of the site with the position of Base Stations and cell boundaries clearly
marked.
yA list of possible configurations to help the customer decide exactly what is required.
yA 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.
yA 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.

Positioning Base Stations
The coverage area for a Base Station within a building varies from 50 to 150 metres.
The radiation graph from a Base Station is almost circular, horizontally, when working
in “free” areas. If a Base Station is placed in the corner of a building, part of the cov-
erage area is outside the building (Figure 1.1). This means that a Base Station
should not be placed in the corner of a building if the required coverage area is within
the building. The shaded area in Figure 1.1 is the “unexploited” area. In practice the
radiation graph will not be as neat as in Figure 1.1, but it is a good starting position
for planning the installation during the site survey phase.
A Base Station should be placed at a minimum height of two metres. If the Base Sta-
tion is any lower, people moving around the building could affect the radio signal from
the Base Station. If the Base Station is placed too high, especially in buildings with a
steel roof, steel girders and/or large air shafts in the ceiling, there is a risk of gaps in
the coverage area. This is party due to “shadows” and/or reflections. The design of
the building, and especially equipment made of metal (shelving, racking, machinery
etc) may effect the radio signals a great deal. For example, in a warehouse where
goods are moving in and out constantly the quality of radio signals can vary from day
to day. Refer to section 1 for more information.
Using the Demonstration Base Station
To find the correct place to locate a Base Station, the Deployment Base Station in-
cluded in the DECT Demonstration and Installation Kit can be used. Refer to the ex-
ample in Figure 1.2. In practice, this method will not result in a symmetric solution as
shown in Figure 1.2, but it does ensure optimum placing of the Base Stations.
A survey and demonstration Base Station is placed in the corner of the building (posi-
tion 1 or 2). The broken circle indicates the coverage area to be measured for the
Base Station. The coverage of the area is defined by the fact that an RSSI value of
85dBm can be measured along the broken line.
Figure 1.1

Part 1: Site Survey and Overview of DECT Systems
13
The RSSI value can be measured with a Samsung D-5000 handset. Note that when
carrying out measurements, the handset must be off-hook.
During measurement it is necessary to take into account the effect a human body
has on the radio signal. This is done by either holding a hand over the antenna of the
handset or by turning the handset and body away from the Base Station in a way that
causes a “worst case” scenario, i.e. a position which results in the lowest RSSI value.
Approximately RSSI 65 / Q52>54 should be measured at the broken line. The Q
value should be stable.
The permanent Base Station should be placed in the position (position 3) in which
the RSSI value is 65 and has a stable Q value of 52 from the measured survey and
the demonstration Base Station in positions 1 and 2. Then the survey and demon-
stration Base Station can be moved to positions 4 and 5. The measuring process can
be repeated and the permanent Base Station is placed in position 6.
Hot Spots
It is possible to have four simultaneous calls on one DECT 1500 Base Station. If the
radio coverage in an area is OK, but users require more than the allowed number of
simultaneous calls, this is called a “Hot Spot”. In a Hot Spot area, additional Base
Stations can be installed.
One or more additional Base Stations can be placed next to the existing Base Sta-
tion. In this way, small overlaps between the coverage areas of the Base Stations are
avoided.
Figure 1.2

Part 1: Site Survey and Overview of DECT Systems
14
A maximum of three Base Stations can be placed next to each other. Any more will
interrupt each other and interfere with the whole system. If there is a need for a fourth
Base Station, this must be placed at least 25 metres away.
Final Testing
The overall performance of the system can only be fully evaluated after the installa-
tion has been completed. If is necessary to move between coverage areas (cells) of
different Base Stations to conclude if the handover between Base Stations is possi-
ble. At the same time, Base Station synchronisation can be tested. This is done by
means of the test display on a handset. It will be necessary to move between the
coverage areas of the different Base Stations to determine whether a handset can
“see” the different cells.
Traffic Measurement
When the cells and radio coverage are in place, the traffic must be calculated for
each cell (Figure 1.3).
Map out where handset users are typically concentrated and calculate how many
Base Stations will be required for each cell. The flowchart in Appendix 1 can be used
as a guide. In Appendix 2, some general calculations have already been made which
can also be used as a guide.
Example: How many Base Stations must be installed in a cell with 40 handsets, as-
suming that 1% of the time users won’t be able to make a call and each handset
makes three calls per hour and each call lasts three minutes?
Figure 1.3

Part 1: Site Survey and Overview of DECT Systems
15
Erlang = E.
3 calls per hour, lasting 3 mins (3 calls x 3 mins)/60 min = 0.15 E
40 x 0.15 = 6 E
With 1% rejection, 6 E equals 12 channels according to the Erlang table (Appendixes
1 and 2).
A Base Station has 4 channels: 12/4 = 3 Base Stations per cell (Figure 1.4)
Troubleshooting with Base Stations
Here are some examples of situations in which problems such as lost calls, bad call
quality or not being able to go off-hook may occur.
Example 1: Several small overlap areas
If you are in an area with a lot of small
overlaps and you are moving in a given
direction, there is a risk of losing the call
because the Base Station which the
handset has as its alternative may not
necessarily be the Base Station that
you are moving towards. This can be
solved by placing a Base Station in the
middle of the area.
Figure 1.4
