3Introduction
- Objective
- To describe the extent to which Brazil has
positioned itself to respond to the impact of the
technological convergence on the
telecommunication regulation in the country.
- 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.
4The 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.

7Regulations toward Convergence
8Regulations toward Convergence
- Regulation for the Use of Paid Mass Communication
Service Networks for the Provision of Value Added
Services (VAS) - Approved through Anatels Resolution nº 190 in
1999. - The purpose of this regulation is
- To make mass communication service networks (DTH,
MMDS, and Cable TV) available for providers of
VAS - To allow the network holder to explore VAS only
through a separated company established specially
for the rendering of VAS - To promote free-market competition features
between Access Network Providers - To make it possible the interconnection of Cable
TV, MMDS, and DTH Networks to the Internet.
9Regulations toward Convergence
- Regulation for Mass Electronic Communication
Services for Subscribers (SCEMa) - Public Consultation yet to be published
- The purpose of this regulation is
- To introduce the term electronic and adequate
the regulatory framework to the current context
of the telecommunications sector - To review and consolidate a single regulatory Act
for pay-TV services - To license services and radio-frequencies
separately - To regulate this service independent of the
technology employed in its provision.
10Regulations toward Convergence
- SCEMa can be provided over technologies as
follows - Coax and Fiber (Cable TV)
- Terrestrial radio-electric waves (MMDS)
- Satellite (Direct-to-Home).
11Systems Characteristics
- MMDS Characteristics
- Telecommunication service which uses
radio-frequency spectrum (2.5 GHz - 2.686 GHz) to
distribute signals (any telecommunication signal)
within the licensed area - Return channel in the frequency band of 2.170 to
2.182 GHz (differs from the U.S. and Canada) - 6 MHz channels
- EIRP Max - 33 dBW considering a 50 Km radius
- The signal transmitted shall be coded by the
operator
12Systems Characteristics
- MMDS Characteristics
- Most of the operations are currently analogue,
but the digitalisation of this system is taking
place and its capacity will increase for the
provision of services - MMDS uses a cellular configuration also split
into sectors - Average Rate of 144 Kbps from the user to the
head-end, using digital modulation.
13Systems Characteristics
14Systems Characteristics
- Cable TV Characteristics
- Cable television network is built up as a public
and unique network - Telecommunication service, which distributes
sound and video programs to subscribers by using
cables (Mainly fiber and coax) - Approximately 80 video channels (6 MHz)
- The return channel is available in the cable
infrastructure - The modulation techniques most used are
Quadrature Phase Shift Keying (QPSK) and
Quadrature Amplitude Modulation (QAM) - Cable TV operators are currently using the Cable
Modem technology to provide interactive services
to users.

17Systems Characteristics
- Characteristics DTH
- Telecommunication service which distributes audio
and video programs through satellites to
subscribers within the licensed area - The operator can use satellite systems either of
its own or leased from a satellite operator - The operator must establish a Monitoring Center
within the Brazilian territory - The transmission of DTH signal is digital
- DTH has approximately 120 video and audio
channels.
18Systems Characteristics
19Regulations toward Convergence
- Regulation for the Multimedia Communication
Service (SCM) - Anatels Public Consultation nº 246 (under
analysis) - Holds capacity for providing multimedia
applications, such as data, image, audio video,
text, etc. (a convergent service indeed) - Can be provided over any telecommunications
network - Public Switched Telephone Service, Broadcasting
Service and Pay-TV Service are excluded.
20Regulations toward Convergence
- SCM Characteristics
- Licensed area may be local, regional or
national - Can be provided over various radio-frequencies,
including 2,5 GHz, 3,5 GHz, 10,5 GHz and 24 -
31GHz, known as Fixed Broadband Wireless Access
(FBWA) - Point to multi-point, uni and bi-directional.
21Regulations toward Convergence
- SCM will support applications such as
- High speed Internet access
- Data communication
- Corporate voice
- Audio and video
- Teleconference
- Tele-medicine
- Tele-education
- Video-on-Demand
- Other.
22Systems Characteristics
- SCM can be provided over various technologies,
mainly over Local Multipoint Distribution/Communic
ation System (LMD/CS). - LMD/CS has the following features
- Capacity to provide convergent services
- Capacity to provide telecommunication services at
high bit rate - Use radio-frequencies around 28 GHz
- Cellular architecture
- Frequencies reuse
- Limited coverage area.
-
23Systems Characteristics
24Systems Characteristics
- LMD/CS Strengths
- Potential to provide a full multimedia service
network package of integrated voice, video and
high-speed data services - Rapid deployment of a multimedia network and the
lower costs for the installation of related
accesses - A point to multi-point network, which offers
further advantages such as faster realisation of
revenue, demand-based buildout, a sort of
fibre-like quality of service, quick response to
market demand and lower network maintenance,
management and operating costs. - LMD/CS Weaknesses
- One of the main problems to be faced by operators
of this system is rain, foliage and dust
attenuation effects causing reduction in the
signal level due to its operation at 28 GHz
frequency band. -
25Anatels Regulatory Action
- Public Consultation nº 291
- On April 17, Anatel published the Public
Consultation nº 291 which has the purpose of
stimulating and broadening the debate on the
choice of the countries DTV standard - This Public Consultation has as its Annexes
- Annex I - Integrated Technical and Market Report
- Annex II - Analysis of Tests (Field/Laboratory)
performed in Brazil.
26Anatels Regulatory Action
- The factors that Anatel is to take into account
in the adoption of a Digital TV broadcast
Standard - Penetration rate of analogue, off-the-air TV in
Brazilian households - Importance of the Brazilian market in the
consolidation of the standard selected on a
global scale - Business and transition models that meet the
needs of the Brazilian population - Identification and analysis of all the factors
involved in the introduction of digital
technology in terrestrial TV transmissions.
