T-DAB+ improvement analyses for The Netherlands
1 Executive Summary
The aim of the study is to estimate the efforts to be spend on the current T-DAB+ network on
channel 11C in The Netherlands to fulfil the future more advanced obligations as laid down in the
memo IGV DAB licenses.
It is expected, that an expansion of the current nationwide T-DAB+ Channel 11C network from
about 54 % demographical portable indoor (PI) coverage to at least 75 % demographical PI
coverage requires a considerable effort. The goal of this study was to estimate this effort by
carrying out an exemplary network improvement planning investigation and determining the
number of required additional (new) T-DAB+ transmitters and the number of current transmitters,
where power increase is needed.
The study indicates that for reaching the coverage obligations of the expansion phase 1 (65 %
demographical PI coverage / 85 % geographical mobile coverage in 2018) an additional effort of 6
new T-DAB+ transmitters as well as a power increase at 3 of the current T-DAB+ transmitters is
needed.
The estimated needs to achieve the requirements of the final expansion phase 2 (75 %
demographical PI coverage / 90 % geographical mobile coverage in 2020) are about 14
additional new T-DAB+ transmitters and about 7 further power increases at current T-DAB+
stations.
This study is an exemplary network improvement planning investigation. It is obvious that due to
the variety of potential procedures and parameters in network planning different ways are possible
to reach the final goals of the advanced obligations as laid down in the memo IGV DAB licenses.
2 Introduction
The objective of this study is to analyse the additional efforts needed to increase the current TDAB+ nationwide coverage on channel 11C to more advanced obligations as laid down in the
memo IGV DAB licenses. The new T-DAB+ radio network obligations are defined as 65 %
demographical indoor coverage and 85 % geographical mobile coverage in 2018 (Phase 1). In
2020 (Phase 2) a demographical indoor coverage of 75 % with a geographical mobile coverage of
90 % has to be achieved.

3.1 Tool adjustments – Wave propagation model ITU-R P.1546
As agreed with the Ministerie van Economische Zaken the propagation model ITU-R P.1546 terrain
was used for these analyses.
This recommendation describes a method for point-to-area radio propagation predictions for
terrestrial services in the frequency range 30 MHz to 3 000 MHz. It is intended for use on
tropospheric radio circuits over land paths, sea paths and/or mixed land-sea paths up to 1 000 km
length for effective transmitting antenna heights less than 3 000 m. The method is based on
interpolation/extrapolation from empirically derived field-strength curves as functions of distance,
antenna height, frequency and percentage time. The calculation procedure also includes
corrections to the results obtained from this interpolation/extrapolation to account for terrain
clearance and terminal clutter obstructions.
The following adjustments, given by customer, were applied during the field strength calculations.

3.2 Tool adjustments – network processor
As agreed with the customer the following depicted network processor adjustments for both
receiving modes are used.

3.3 Weighting Function T-DAB+
For summation of useful and interfering signals the DAB weighting function (rectangle) shown in
the figure below is used for the guard interval of 246µs. Thereby the red line shows the useful part
and the blue one the interfering part.
Figure 4: Weighting function T-DAB+
3.4 Locking Mechanism for T-DAB+
level
For the DAB calculation the receiver synchronization Main Focus will be used. Based on this
locking mechanism the receiver synchronizes in a way that the highest field strength of a group of
signals is inside the Guard Interval.

4 Maps
The field strengths predictions are calculated based on digital terrain maps and land-use maps
(clutter maps) with a resolution of 500 m according the customers requirement. The population
analyses were done by using a population map with a resolution of 100 m and for visualization
purposes, an European overview map was used. The figures below show an excerpt of these
maps.

6 Planning approach
As mentioned before the current T-DAB+ network, operating on channel 11C, has to be improved
in two phases.


65 % demographical portable indoor with 85 % geographical mobile coverage in phase 1
75 % demographical portable indoor with 90 % geographical mobile coverage in phase 2.
This should be achieved by power increase of the current T-DAB+ transmitters on channel 11C
and/or by adding further new transmitters.
New site locations, required for the implementation of additional transmitters, are based on a site
database provided by customer. This database comprises sites in The Netherlands currently used
for different broadcast services (DAB, DVB, FM).
It was preferred to place additional required transmitters more interior of The Netherlands and less
close to land border to avoid additional interference into neighbouring countries if possible. For the
same reasons it was also tried to avoid power increase on existing transmitters close to the land
border if possible.
Concerning power increase as well as selection of new transmitters it was intended to orientate on
the parameters as well as network structure of the existing nationwide T-DAB network on channel
12C, which already offers an improved nationwide coverage.
For new added transmitter sites a standard omnidirectional 4 panel / 4 bay antennas with a gain of
about 8 dBd, as shown in following picture, was used.
Figure 11: Standard omnidirectional antenna
This study is an exemplary network improvement planning investigation. It is obvious that due to
the variety of potential procedures and parameters in network planning different ways are possible
to reach the final goals of the advanced obligations as laid down in the memo IGV DAB licenses.

8 Conclusion
The aim of the study is to estimate the efforts to be spend on the current T-DAB+ network on
channel 11C in The Netherlands to fulfil the future more advanced obligations as laid down in the
memo IGV DAB licenses.
It is expected, that an expansion of the current nationwide T-DAB+ Channel 11C network from
about 54 % demographical portable indoor (PI) coverage to at least 75 % demographical PI
coverage requires a considerable effort. The aim of this study was to estimate this effort by
carrying out an exemplary network improvement planning investigation and determining the
number of necessary additional (new) T-DAB+ transmitters and the number of current transmitters,
where power increase is needed.
The study indicates that for reaching the coverage obligations of the expansion phase 1 (65 %
demographical PI coverage in 2018) an additional effort of 6 new T-DAB+ transmitters as well as a
power increase at 3 of the current T-DAB+ transmitters is needed.
The following table shows the initial transmitters, where power increases were done as a
contribution for the coverage improvement of the T-DAB+ network as required for expansion
phase 1.

Table 7: Additional new transmitters (Phase 1)
(*after bandpass filter - find detailed transmitter output power calculation in Annex A)
The estimated needs to achieve the requirements of expansion phase 2 (75 % demographical PI
coverage in 2020) are about 14 additional T-DAB+ transmitters and about 7 further power
increases at current T-DAB+ stations compared to phase 1.

Table 9: Additional new transmitters (Phase 2)
(*after bandpass filter - find detailed transmitter output power calculation in Annex A)
The exemplary network improvement study reached also the mobile geographical coverage
requirements given for both expansion phases.
This study is an exemplary network improvement planning investigation. It is obvious that due to
the variety of potential procedures and parameters in network planning different ways are possible
to reach the final goals of the advanced obligations as laid down in the memo IGV DAB licenses.
