Introduction
Rural and remote areas telecom case :
usually not interesting from business point of view
telecom development should be supported by government

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

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
