Strong Presence at
ITU Study Groups
LS telcom has a long-standing commitment
to regularly attending ITU
Study Groups.
LS telcom is currently attending 3
Study groups: WP 3K (point-to-area
propagation), WP 4A (effi cient orbit/
spectrum utilisation for FSS and
BSS) and WP 6A (terrestrial broadcasting).
This way LS telcom receives
the information at fi rst hand
and is thus able to provide its customers

New CHIRplus_BC v. 5.6.0 Release includes DVB-T2 and ISDB-T Planning Functions
The new CHIRplus_BC version 5.6.0
for broadcast planning and coordination
now covers DVB-T2 as well as
ISDB-T planning functions, whereas
the last major release 5.4.0 concerned
multi-core calculations.
The new version has already been
delivered to customers under
maintenance.
DVB-T2, which is also subject to ITU’s
Recommendation BT.1877, “Error-correction,
data framing, modulation and
emission methods for second generation
of digital terrestrial television
broadcasting systems”, offers enhanced
fl exibility to broadcasters,
ranging from physical layer pipes
(PLPs) to MISO (Multiple-Input Single
Output). The advantage of MISO is that
two variants of the signal can be transmitted
from different sites, offering
more network gain than the SFN operation
known from DVB-T.
Many countries – especially developing
countries – are considering adopting
this second-generation system
immediately after their future analogue
switch-off (ASO). South Africa
and Mozambique in Africa and Serbia
in Europe have decided to take a short
cut and change directly from analogue
technology to DVB-T2.
CHIRplus_BC takes into consideration
the higher complexity which comes
with the DVB-T2 system, with more
parameters than the classical DVB-T,
and offers enhanced confi guration
possibilities and pre-sets for the various
T2-constellations and reception
modes.
As not all combinations of pilot pattern,
constellation and guard interval,
etc, are possible
according to the
DVB-T2 specifi cation,
the user is
only able to select
valid combinations
in CHIRplus_BC.
The “pilot pattern”
selection shows
only those in green
that result in a valid
combination.

Vendor independent, on schedule and in line with your budget
A broadcast network that is optimised in terms of technology, quality of service, capital expenditure, and long-term cost effi ciency, needs to be well-planned.
At LS telcom, we cover the entire Broadcast Network Life cycle from Design and Planning through Procurement, to Implementation and Optimisation.

Nationwide Hybrid TV DVB-T2 Network Study in Asian Country
A private broadcasting
company in an Asian country
asked LS telcom to carry
out a nationwide DVB-T2
study in order to offer
hybrid TV to its customers.
LS telcom designed several nationwide
single frequency networks (SFN)
based on the required data capacity
and reception mode. The objective
was to optimise the system in terms
of the number of sites used and the
targeted coverage area and population.
The study included the selection
of the most suitable DVB-T2 system
technology.
LS telcom also carried out interference
analyses with respect to analogue
TV in the country, analogue and
digital TV on borders and with respect
to non-broadcasting services.
This went along with measures to
reduce or avoid interference.
At the end of the study LS telcom set
up the Request for Information (RFI)

DVB-T2 proposals were analysed
and evaluated based on several
criteria like equipment, price quote,
schedule, customer service plan and
reputation. �

LS telcom was also present at the
ABU (Asia-Pacifi c Broadcasting
Union) conference in Bangalore,
India, from 12th - 14th July. More
than 60 broadcast experts from
mainly Asian countries attended
this conference.

Pre-Built Transmission Container Installations
LS of South Africa now provides
high power digital broadcast
transmitter turnkey installations.
The facility and capacity ranges
from container installation to
testing and build-up through to
commissioning to the point
where the containers are ready
to operate.
Planning of DVB-T2 Networks (White Paper)
The White Paper provides an
overview of major techniques
used in DVB-T2 and their impact
on service planning and operation
of this new transmission technology.
It outlines the increase in capacity
through robustness gain achieved
by rotated constellations and
Q-delay.
UHF Television Spectrum Audit - Nigeria
LS of South Africa recently performed
a spectrum audit of UHF television
frequency usage in Nigeria.
The idea behind this was to create an
accurate frequency database to
determine which frequencies will be
avail-able for DTT implementation.
The sources of information used
during the investigation included the
Geneva 06 analogue and digital frequency
lists, the National Broadcasting
Commission (NBC) list of
frequency assignments and the information
obtained during our national
frequency meas-urements.
The measurements were done using a
Rohde & Schwarz EB200 receiver
In parallel to recent innovations in the
area of fl ight control and embedded

There, the LS team fi ts out the container

High Demand for
CHIRplus_BC

Wave Propagation
Model Calibration -
Zambia
LS of South Africa was recently
requested by a client to perform wave
propagation model calibration for a
client in Zambia.
The calibration was done for CHIRplus_BC
and more specifi cally for
DVB-T2 coverage predictions.
A FSH6 Spectrum Analyser from
Rohde & Schwarz with a GP600
antenna was used together with a GPS
and a laptop for the data logging. The
antenna pattern and gain were analysed,
cable losses were measured
and the complete measuring system
was calibrated. The measurements
included all morpho classes over a
large coverage area.
The results were analysed with
CHIRplus_BC v560 and all the
measurements were then divided
into the different morpho classes.
Our wave propagation prediction
model was then calibrated against
the measured values. A sample of
such results is included below. �
