BroadBand Cities 2008 – Trikala, Greece October 20-23,2008

Best practices (1/2)

The term “best practices” includes the actions, the strategies, the practices and the laws

that several countries, cities or communities have applied for development of broadband

Best practices (2/2)

Factors that influence : The regulatory framework The foundational changes that take place in the

Information Technology and Technology markets The changes in bandwidth services and their

use The technology development The users’ need for faster access to content The cost The electronic readiness (e-readiness) and in

general the technological level of a country

Quality Comparison (2/2)

Comparative study point-to-point versus point-to-multipoint

Advantages Disadvantages

Point-to-point

Better Technology with no flexibility and improvement limitations Better network managemenet . Easier handlingUnbundling Capability

Higher CAPEX costs (initial costsHigher OPEX costs (operational costs ) due to space needs and probably current needs (for active networks)

Point-to-multipoint

Lower CAPEX costs (initial costs )Lower OPEX costs

improvement uncertaintyUnbundling difficulties Cost increases as subscribers increase

Important Strategic Decisions

FTTH Potential Development from 2006 to 2011

Broadband Performance Index (1/2)

Πηγή: EU 26

Broadband Performance Index (2/2)

European broadband market is developing at a fast pace

Some of the European countries are globally at head As long as the market grows, there is a need for

evaluating European Union’s alertness for promoting the development of broadband access

The new Broadband Performance Index (BPI) is the current standard for measuring the presence of member countries in a commercial level, that inludes Speeds Rural areas coverage Financial tolerance Innovation More Social-financial components

Cost Factors The cost depends on:

FTTH Architecture Material Prices Existing Infrastructure (underground or

air infrastructure) Characteristics of ground/ underground Cost for Working Urban/Suburban/Rural (houses/km2)

Costs in percentage during the first year of the installation of a new optical fiber network

Implementation cost in different markets

Implementation cost per technology per area Areas:

Α: Rural B: Urban C: Remote

Installation of Optical fiber network & CapEx

Who and How will realize it

There are several schemas Partial State intervention Full State intervention

Or… combination of the above What is the role of local authorities? What is the position of the market? What will happen with the MANs?

Argument in favor of government-sponsored broadband networks

Argument against government-sponsored broadband networks

Note Streets were built in order to

provide transportation for all vehicles (OPEN ACCESS)

BROADBAND IS A PUBLIC INFRASTUCTURE WITH GREAT IMPACT ON LOCAL ECONOMY AND DEVELOPMENT

Verdict
