1 INTRODUCTION
1.1 ABOUT THE SITE SURVEY TOOL
The Site Survey Tool is used by technicians to plan base station locations for a DECT
telephone system with TDM-DECT or IPBS base stations. With the Site Survey Tool
you can determine the required number and positions of base stations.
By using the Site Survey Tool and one or two base stations, the radio coverage of a
base station can be determined. Two base stations are required when IPBS base
stations are used and if air sync is considered.
A connection with a PBX is not required when using the Site Survey Tool. The Site
Survey Tool is available in two versions. One with battery units and chargers. And one
without battery units and chargers.

3 THE SITE SURVEY TOOL IN THE HANDSET
The Site Survey Tool in the handset provides two major features; indications of radio
signal quality and base station listing.
Radio signal quality involves both signal strength and frame error rate. This tool may be
used when planning a site's radio coverage and to find radio quality problems.
Base stations lists may include all base stations within range of the phone, sorted in
signal strength order. This feature may be used to find other interfering DECT base
stations.

4 SITE SURVEY WITH IPBS BASE STATION
NOTE: If the Enhanced DECT Security feature is to be used in the system (to gain
early encryption and re-keying) then the Enhanced DECT Security feature must be
activated before performing the site survey. For information on Enhanced DECT
Security, see about Enhanced DECT Security in the System Description
documentation for IP-DECT. For information on how to activate Enhanced DECT
Security, see the Installation and Operation Manual for IP-DECT.
If the planned system shall have an IPBS, both speech coverage and sync coverage
have to be considered. If the system only consists of IPBL, only speech coverage has
to be considered.
Speech coverage: the radius of the circle (circular radiation patterns of the IPBS
antennas are assumed for reasons of simplicity), around a particular IPBS, in which
portable parts can communicate with that IPBS, see figure 6.
Sync coverage: the radius of the circle, around a particular IPBS, in which other IPBSs
can synchronize with that IPBS with a given synchronization loss probability. This
means that the size of the sync radius depends on requested probability of losing
synchronization, see figure 6.
Figure 6. Air- and speech sync radius.
4.1 START BY PLACING TWO BASE STATIONS IN THE SITE
Use the GUI web interface to configure IPBSs. For more information about the GUI
web interface, see the document Installation and Operation Manual for IP-DECT Base
Station.
1 Configure IPBSs as Master and Pari Master inclusive PARI and SARI.

3 In the PARI Master IP Address text field, enter loopback address 127.0.0.1.
4 If the base station shall be used without a network and a DHCP server, a static
IP address must be set. Do as follows:
Select LAN > DHCP. In the Mode drop-down list, set the DHCP mode to
"disabled".
Select LAN > IP. In the IP Address text field, enter an IP address, e.g.
192.168.0.1
5 Set base station A in deployment mode.
6 Set base station A as Sync master
7 Register one DECT handset in Base station A
8 Configure base station B as base station A using the same system ID, PARI and
SARI. Note: It is recommended to use different IP addresses
9 Set base station B in deployment mode.
10 Set base station B as Sync Slave.
11 Base station A shall be placed the first time on the planned location for the Sync
Master (should be in the middle of the site).
4.2 CHECK THE SPEECH COVERAGE FOR BASE STATION A
12 Check on the DECT handset that the signal strength is > -68 dBm which is the
normal case to get sufficient speech quality within each base station.
13 Verify that the speech quality is sufficient by listening on a call. When the off-
hook key is pressed, the speech is looped back. However, when the off-hook key
is pressed on an anonymous DECT handset a dial tone is heard and when a
digit is pressed the speech is looped back.
In certain environments, for example reflective environments (large rooms with
lots of metal), there might be a need for a considerable stronger signal strength
more than -68 dBm in order to get sufficient speech quality.
14 Mark on a map the position and the speech coverage for base station A.
4.3 CHECK THE SYNCHRONIZATION COVERAGE
15 Use the GUI web interface on base station B and check that the signal strength
from base station A to base station B is stronger than -83 dBm. If this is not the
case then you should consider to move base station B closer to base station A to
get a stable synchronization coverage for a longer time.
For IPBS4x2/IPBS2: You can also check the synchronization by looking at the
LED on the base station IPBS4x2/IPBS2, see figure 7 on page 13. For a
description of LED deployment indications, see the diagram in figure 8 on page
13. When indicating no sync (LED flashing red and yellow) it might take some
additional time (10 to 30 seconds) to regain synchronization when entering the
sync coverage again.

16 Use the GUI web interface on base station B and check the signal strength on
the actual synchronization coverage and name it X.
17 Perform an RFP scan. If there are other DECT systems that are stronger than
(X-6) dBm, move base station B closer to base station A and then repeat from
step 10 above. For example, if X = -80 dBm then there must be no other DECT
systems that are stronger than -86 dBm.
4.4 TO PERFORM MEASUREMENTS FOR OTHER BASE
STATIONS
18 Move base station A to the position where base station B is located.
19 Place base station B on the next planned position.

5 BROADCAST AND MULTICAST MESSAGING
Special requirements need to be considered when planning a system for broadcast and
multicast messaging.
Broadcast and multicast messages are without any handshake procedure between the
base stations and the handsets instead a number of retransmissions are being made to
increase the probability of a complete transmission. The sending application receives a
confirmation that the message has been sent and received by the radio exchange/base
stations but not the handsets.
Advantage of sending broadcast/multicast messages:
• Quick transmission to a large number of users
• Low system capacity usage
Disadvantage of sending broadcast/multicast messages:
• No individual technical confirmation, thus lower security
An appropriate value for installations where broadcast and multicast shall be used is to
always have field strength above -65dBm.
