Presentation : motivation and content:
Rural and remote areas telecom case :
usually not interesting from business point of view
telecom development should be supported by government
Content:
First, this presentation discusses the characteristics of the rural
and remote areas through statistical data for different telecom
indicators
Next, case studies with planning of broadband wireless in the
access network of rural and remote areas are presented
Finally there is a summary of the requirements to the planning
models and tools

Largest cities vs. rural areas - user behaviour
Findings of the United Nations :
all growth in population will concentrate in
urban areas, no growth in rural areas
most of the growth will concentrate in urban
areas of less developed regions
Users will concentrate in urban areas,
areas, as urban areas put
higher pressure on the individual to "do what the others
do" and from technical point it is easier to connect people
in urban areas

EU Project - Broadband for All
To develop the network technologies and
architectures allowing a generalised and affordable
availability of broadband access to European users,
including those in less developed regions,
peripheral and rural areas.
Optimised access technologies, as a function of the
operating environment, at affordable price allowing
for a generalized introduction of broadband services
in Europe including less developed regions

Conclusion for the rural and remote areas
characteristics
There is difference between rural and urban
telecom development, which depends mainly
upon the country development (e.g. low income,
high income countries)
Broadband access depends on the IT
penetration in the country and that will influence
the rural and remote areas BB access
In every region of the world there is diversity
of different countries (as low income, high income,
etc.) which should present different requirements
to the rural and remote areas BB access

Planning case studies performed with
available network planning tools
The case studies present the planning process
that needs to be performed for evaluation of
wireless broadband access in rural and remote
areas
Planning includes market definition and
optimization of the access network. First
access network is optimized regardless of the
terrain characteristics, then network is
analysed for coverage and result is adjusted
correspondingly
The case studies are planned with professional
NP tools, available through ITU partners

Planning tools - LStelcom MULTIlink
MULTIlink is a complete solution
for fast microwave link
engineering and designing of
PMP/WLL/LMDS networks.
It can be used for planning and optimizing single links (e.g. path loss,
coverage and availability calculations) as well as for doing network-wide
analysis (e.g. interference calculation, channel assignment).

Conclusion for planning of bradband
wireless access
Service/market forecasting, access network
optimization and economic analysis are main
phases of planning also for broadband wireless
access in rural and remote areas
Planning of broadband wireless access
requires additional analysis with regard to
evaluation and optimization of the terrain
coverage
Effective planning of broadband wireless
access in rural and remote areas includes
application of appropriate planning tools

Service areas :
E.g. optimal service areas of a BS
wireless resource is limited, i.e. not possible to have several BS in the same or
nearly the same location, as is the case with wireline nodes (e.g. DSLAMs)
in some wireless technologies served area is function of the traffic load (the
sells breathing effect)

areas of less developed
regions
