Outline
• e-Learning– Definition– Types– Benefits– Problems
• Broadband (the solution)– Broadband in Greece– Broadband strategy in Greece– Municipal broadband networks - Call 93
3Broadband Education Services,11-12 June 2009, Crete, Greece
e-Learning
• e-Learning is a type of technology supporting education / learning where the medium of instruction is through computer technology, particularly involving digital technologies– The worldwide e-learning industry is constantly increasing– The supported applications become more and more
demanding– The number of students participate in online classes
increases
• e-Learning has high bandwidth requirements– Live audio-visual communication– Rich and high-quality (multi-)media (e.g. video)– Access to intensive simulations’ results
4Broadband Education Services,11-12 June 2009, Crete, Greece
Types of e-Learning
• Asynchronous– Services
• E-mail• Online Courses• Discussion boards• Presentations• Webinars• Video (streaming, on-demand, etc.)
• Synchronous– Services
• Chat• Audio Conference• Video Conference• 3D Virtual Environments
– (Harvard University delivers online courses through Virtual Environments)
Higher bandwidth requirements
5Broadband Education Services,11-12 June 2009, Crete, Greece
e-Learning Content
• Rich media– Webcasts– Videos– Simulations– 3D content– Images (high quality)– Audio (high quality)
• Bandwidth is one of the most critical factors
6Broadband Education Services,11-12 June 2009, Crete, Greece
e-Learning Benefits
• Bring the classroom to the students
• Bring more things to the classroom
• Live, interactive, anywhere
• Reduce faculty travel
• Substitute professors when necessary
• Faculty can teach while traveling
7Broadband Education Services,11-12 June 2009, Crete, Greece
Why e-Learning…
• Allow learning for remote areas and/or undeveloped areas
• Can allow “virtual” laboratories – All schools can acquire virtual laboratories for all
courses– e-Learning constitutes an economical solution against
real laboratories
• Lack of available space– Virtual laboratories for all courses can be found in the
same room
8Broadband Education Services,11-12 June 2009, Crete, Greece
Problem definition
• Some places still at dial-up speeds
• Still expensive
• Too slow for many applications
9Broadband Education Services,11-12 June 2009, Crete, Greece
The Solution
• Broadband is the solution to the problems and limitations
– Provides Faster Connections
– Supports more applications• Video (SD and HD)• Interactive rich media• High resolution graphics
10Broadband Education Services,11-12 June 2009, Crete, Greece
Why Broadband…
Recently, fast progress in Information and Communication Technologies (ICT) has favoured new operational models and introduced significant changes both at national and global financial levels
The supporting base for the competitiveness of a State in today’s high technology environment actually consists of advanced and high quality network infrastructures, reasonably priced, that are available to the majority of the population and provide users with always-on connectivity at sufficient speed
…Broadband access networks, from a technological aspect, can meet all these modern requirements.

Broadband strategy in Greece
14Broadband Education Services,11-12 June 2009, Crete, Greece
Calls 93, 145 and 195
Finances for the implementation of Metropolitan Optical Fibre Networks
These networks, interlink the buildings of the state, local
authorities, and public agencies in their respective municipality (Governance, Education, Health, Culture)
The project includes the installation of fibre optics, the
creation of points of interconnection and the
installation of passive and active network equipment
that is required for providing the basic access as well as points of wireless access.

An Example…
• MAN of Agrinio: 44 end users, 20 of which are schools
19Broadband Education Services,11-12 June 2009, Crete, Greece
Target
• Provide broadband education, awareness, training, access, equipment to:
– Schools, libraries, healthcare providers, institutions of higher education and other community support organizations to facilitate greater use of broadband
– Organizations that provide outreach, access, equipment and support services to facilitate greater use of broadband by low-income, unemployed and vulnerable populations
20Broadband Education Services,11-12 June 2009, Crete, Greece
Municipal broadband and the educational sector
• Universities, Technological Education Institutes, and schools are the first to make real use of the municipal broadband networks built
• For schools it will be a real upgrade to their connectivity, and a move to true broadband experience– Universities and Technological Education Institutes, already
enjoy high-bandwidth connectivity, but the use of the municipal broadband infrastructure is going to cut down the costs
• The demand for broadband connections and a lot of services are already there.– These are the reasons that schools are going to make a
effective use of the broadband infrastructure provided
21Broadband Education Services,11-12 June 2009, Crete, Greece
Plans for the future
• The Greek State aims to co-finance and support the deployment of Fiber-to-the-Home (FTTH) infrastructure to Athens, and Thessaloniki (greater areas), and 54 other major cities in Greece.
• The infrastructure will allow the use of demanding e-learning services not only from school but also from home
• This opens new opportunities both for developing novel e-learning approaches and innovative applications
