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

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

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)

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
34
Argument against government-sponsored broadband networks
35
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
