on
the
Argument
 The implications of the technological convergence on current
regulatory regimes clearly indicate that they will be subject of
revisions.
 The actions to be taken on these regimes, it is argued, need to be in
line with the expectations of service providers and consumers in the
sense of promoting greater benefits for the society as a whole under
an increasing availability of convergent services.
The Technological Convergence
Conceptual Approach
 Technological convergence is defined as a process of formation
of successive similarities amongst technologies that had been
distinct from one another. They have once established clear
borderlines amongst the services they have enabled the provision
but now share a common digital environment.
The Technological Convergence
Response of Regulatory Authorities
 Full legislation and regulatory reform requires a long-term in-depth
assessment of the technological convergence;
 Technologies and services are evolving rapidly and leaving a large number of
legal and regulatory provisions lagging behind;
 Regulatory uncertainties must be expeditiously and timely removed, in order
for the pertaining industries to continue to grow;
 Initial step toward a future flexible regulatory framework:
 to consider technology and platform as neutral so that new
developments in services, be they incremental or radical innovations, can
be easily accommodated.

Introduction
 Analysis of the impact of the technological convergence on the Brazilian
telecommunication market to be carried out by Anatel and Specialized
Consultants.
Objective
 Expose about the impact of technological convergence in
telecommunications sector, including the radio broadcast and IT sectors.
the
 Review the telecommunications regulatory regime in the country, including
the radio broadcast and IT regimes presently in force;
 Develop a regulatory framework that do not hinder the growth of the
telecommunications sector, including the radio broadcast and IT sectors, and
that foster, at the same time, technological innovations that can be extended to
all associated industries.
Future Actions
Expected Products
 An analysis of the current and future setting, the risks and opportunities for
the development of the telecommunication sector, including the radio broadcast
and IT sectors;
 A description of the future scenarios for the technological development of
these sectors and how these elements can contribute to the various modes of
telecommunications (voice, data, video, multimedia, etc. signal transmissions)
in urban and rural areas;
 A regulatory and licensing framework that is capable of promoting the
compatible development of communications, the redesign of Anatel’s
organizational structure and competencies, and the establishment of an action
plan for adjusting to the changes.
Conclusion
 While the process of technological convergence progresses the world
over, policy strategies need to be found on the extent to which the
pace toward the establishment of multimedia services can be
accelerated, whereas we all share the idea of the direction the whole
global society is heading;
 Back to the concept of evolutionary process that telecommunication,
broadcasting and computing technologies have embarked on, it can
be asserted that the digital environment has set the direction for an
ubiquitous provision of convergent services in the very near future.
