Using the DECT Site Survey Kit
Summary
A 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 DECT base station and any repeaters.
For full details of surveying and the positioning of equipment refer to the Compact
DECT Installation Manual and the DECT Installation Manual.

Guidance on where to start the survey and order in which to do a survey is
difficult, each case is unique and much relies on experience. Ensure that
conditions are as near to normal as possible, ie. if possible do the survey
on a normal working day when the building is in use. Check which areas
you can enter and when.
The Survey Base Station
The Survey Base Station is a DECT Base Station able to transmit without
being connected to a telephone system. It is supplied with a suitable mains
power supply unit. As well as providing an RSSI/Q52 signal it can accept
audio input via a 3.5mm audio-jack input for a user audio quality check.
Power Supply Input:
9VDC 150mA.

Audio Input
– Power Socket:
The Survey Base Station is supplied with a suitable power supply
terminated with an RJ11 connector. The connector uses Pin 6 (-ve) and
Pin 5 (+ve) to provide a 9V dc, 150mA supply.
– Audio In Socket:
Standard 3.5 mono jack socket input.
– Subscribe Button:
If pressed and held for 3 seconds, puts the Survey Base Station in
subscribe mode for the following minute. The base stations system
ID is printed on its back. Its account number is 1234 (on older
versions this may be 12345678).

Using the DECT Site Survey Kit Subscribing to the Survey Base Station
Subscribing to the Survey Base Station
Up to eight handsets can be subscribed to the Survey Base Station. All
these handsets can display the RSSI signal quality simultaneously but only
one can receive the audio input at any time. Normally only one handset is
subscribed to the Survey Base Station.
1. Connect the Survey Base Station to it's power supply and switch on.
2. Turn the handset on. Assign it a number between 1 and 8 by dialling
*99972*xwhere xis the number between 1 and 8. Then press ✓.
3. Press MENU and the >key until LOGIN appears and then press ✓.
SELECT LOGIN appears. Before subscribing to system, you are
recommended to remove all other subscriptions (steps 4-6).
4. Press >until SUBSCRIPTION REMOVE appears and then press ✓.
5. Enter the password (default 0000) and press ✓ to display
SUBSCRIPTION REMOVE? Press ✓to display any previously entered
System ID (appears below SYSTEM X, where X = 1 to 4). Press ✓ to
remove.
6. You are returned to SUBSCRIPTION CREATE. Press >until
SUBSCRIPTION REMOVE appears. Repeat from step 4 for all
previously entered System IDs.
7. When completed, press MENU twice and then press >until LOGIN
appears. Press ✓ to display SELECT LOGIN and press ✓ again to
display SYSTEM X, where X = 1 to 4). Use >to select required system
number and press ✓.
8. Press >to display SUBSCRIPTION CREATE and the press ✓ to
begin subscription. The handset is searches for a system to which it
can subscribe. Press and hold the subscribe button on the Survey
Base Station for 3 seconds. The Survey Base Station will then stay in
subscribe mode for one minute.
9. Use the <and >buttons to display the ID numbers of available DECT
systems found by the handset. Look for the ID number of the Survey
Base Station (printed on the back of the Survey Base Station) and then
press ✓.
10. Use the <and >to select which system number you want the Survey
Base Station assigned to and then, at the AC: prompt, enter 1234 (or
on older systems 12345678) and press ✓.
11. SUBSCRIPTION WAIT appears. When successfully subscribed, the
handset bleeps. Should SUBSCRIPTION FAILED appear, repeat from
step 8.

Performing the Survey
Position the Survey Base Station in the potential position for a base station
installation. Connect the power supply. If possible, also connect an audio
source via either the telephone line or audio jack sockets.
1. With a subscribed handset on-hook, dial *99981* and press ENTER.
2. The handset display shows the signal quality.
RPN: 01 << Base station number.
Q52: 52 << Speech quality (target 52+).
RSSI: 64 << Signal strength (target 64+).
3. Take the handset off-hook as this will ensure more realistic figures.
– If you have connected an audio source you will hear it whilst off-
hook. Use this facility to check the audio quality (only one handset
can be off-hook and receive the audio source at any time).
4. Check the boundaries of the Survey Base Stations coverage where
Q52 is greater than 52 and RSSI is greater than 64. Mark this area
on the building plans for all areas that the CDBS might have to serve.
5. Where Repeaters are to be used, repeat the above process.
6. To return the handset to normal operation, press and hold <until you
hear a short bleep.

Using the DECT Site Survey Kit Base Station Coverage: In Practice
Base Station Coverage: In Practice
In practice, no rules can be given for base station coverage. Coverage is
affected by too many factors that are unique to each site. We can only
guide you as to those things that are likely to affect base station coverage.
Obvious causes of signals problems:
– Metal surfaces.
– Concrete thickness greater than one metre.
Beware of:
– Windows with reflective film or specialised glass:
These produce increased signal reflection and reduced signal pass-
through.
– Wire Meshes and Grills with apertures of less than 4cm:
These block signals as effectively as continuous metal sheet.
– Fire Doors:
These block the signals. In multi-occupancy building such as hotels
the high number of fire-doors may be a problem.
– Stair Wells:
In modern office buildings, stair wells frequently combine concrete
building supports, fire doors and the intervening floor material,
making them a special problem.
– Screened Rooms:
Typically found in offices involved with TV, video and radio
production, but also possible in computer centers.
Opportunities to be aware of:
– In multi-storey buildings, if the building construction allows, a base
station on one floor can also serve the floor above or below.
