4 Overview of the Current Regulatory Environment in South Africa International Telecommunications Reform
• Early 1990’s - end of telecommunications natural monopoly across the world as administered by governments
• Economic and technological developments necessitated a review of the treatment of telecommunications
• WTO, ITU, EU and other international bodies reassessed the increasing importance of telecoms and its expanded role in the market
• The above resulted in telecoms reform and the design of the so-called optimal institutional structure

The policy reform process in the telecom industry is being conducted in three phases:
Phase 1: 1996 - 2002/3 Sectoral Reform
Phase 2: 2002/3 – 2007 Managed Liberalisation
Phase 3: 2007 – beyond Full Liberalisation
8 SA Telecoms Market - Historical and Expected Developments
2007 - Full Liberalisation
2005 – Convergence Legislation expected
2004 – SNO Licence Granted
2003 – Telkom Listing
2002- End of Telkom’s Exclusivity
2001 – Telecommunications Amendment Act
2001 - 3rd Cellular Licence 1997 - Telkom Licence 1996 - Telecommunications Act 1993 - Cellular Licences
1991 - Creation of Telkom Ltd
9 Managed Liberalisation
• SA opted for managed liberalisation of the telecoms sector has gradually opened to competition while ensuring optimum utilisation of existing investment in the sector
• A big bang approach would have opened up the sector quickly and offer many services from different network operators, but this approach could potentially have eroded SA’s public and private investment
10 History of the Regulator in SA
1993 1997 Independent South African Broadcasting Telecommunications Authority Regulatory (IBA) Authority (SATRA)
2000 Independent Communications Authority of South Africa (ICASA)
11 Role of the Regulator – ICASA
• ICASA regulates the telecommunications and broadcasting industries in the public interest. Its key functions are to:
! make regulations and policies that govern broadcasting and telecommunications ! issue licenses to providers of telecommunication services and broadcasters ! monitor the environment and enforce compliance with rules, regulations and policies ! hear and decide on disputes and complaints brought by industry or members of the public against licensees ! plan, control and manage the frequency spectrum and numbering resources ! protect consumers from unfair business practices, poor quality services and harmful or inferior products
12 The Independence of the Regulator
Conditions necessary Experiences in for an Independent South Africa Regulator
" Guiding principles on the " ICASA been challenged by Regulator mandates operators on flawed administrative procedures " Decision making process " Act provides for decisions made should be transparent by ICASA to be approved by the and independent Minister " ICASA is funded by the " Funding Government and not through license fees " Adequate resources and " ICASA plagued by limited capacity resources e.g. HR on key ICT 13 competencies Regulatory Challenges facing the Sector
• Funding of the Regulator
• Convergence
• Globalisation ‐ Regional Regulator? ‐ Continental Regulator?
• Adequacy of ICT Skills

• Control centre in Cape Town • Main/Core Site (correlator) – Karoo 2D1 • Remote Sites – South Africa – 51 – Namibia – 6 – Botswana – 6 – Swaziland – 1 – Mozambique – 1 – Mauritius – 1 – Madagascar - 1
131 SKA Bandwidth and connections
• The capacity requirement are as follows:
• Main site (correlator) and Control site (Cape Town) – 3.8 Tbps
• Main site (correlator) and each Remote site – 152 Gbps
• The control centre in Cape Town needs to be connected to SKA users in other parts of the world
132 SKA Timelines
• 2000 International SKA Steering Committee formed • 2002 International SKA Management Plan established • 2005 International agreement on sites • 2007 International agreement on technical implementation • 2009 SKA scientific and technical proposal • 2012-2020 SKA construction
133 Pros/Cons
Pros • Boost SA’s status in scientific arena • $1B budget for SKA project • Foreigners investing in SA • Tourist attraction
Cons • Most of the $1B investment will be spent on R&D and manufacturing (which will be done by mostly international companies) • Severe limitations on future radio developments (including radar, wireless-telecommunications, Cell phone coverage, Television and radio broadcasting)
134 close to SKA sites and its remote sites (spirals) Question and Answer Session Convergence and its impact on SA Telecoms What is Convergence?
• There is no universal definition of Convergence.
• Convergence can mean:- – “Provision of various communication services like text, data, – image and video over the existing infrastructure”
– “Development of new infrastructure for handling multimedia transmission”
– “Managing of technologically and commercially distinct markets such as Broadcasting, Publishing, Cable TV, Fixed Voice, Cellular Mobile Services and Internet 137 Services” Types of Convergence ?
• Convergence of Technologies : – A common platform to deliver Voice, Data and Video services
• Convergence of Services: – Delivery of multiple services to the end users over the same medium/ network
• Regulatory Convergence: – Establishing a single Regulatory Authority by blurring the regulatory boundaries for telecommunication, information technology and broadcasting 138 Drivers of Convergence…1
1. Technology – Digitisation of transmission and switching networks – Global networks based on packet switching and open standards (IP) – Increase in Processing power of Computers – Emergence of new applications (ICT) leveraging enhanced software capabilities – Evolution of Broadband technologies(xDSL, CMTS, HFC, Broadband wireless- Fixed/ Mobile, Satellite)
2. Market – New markets and services such as Multimedia services,Video on demand, Interactive TV, Pay TV,Cable telephony,Unified Messaging services, Internet Telephony etc. – Integration of content service providers with access providers – Emergence of new Market players based on Potential of ICT 139 Drivers of Convergence…2
3. Customers – Option for new value added services in a modular fashion – Cheaper access to communication – Single Information Socket (for phone, data, video)
4. Regulation – Reduction in cost of regulation by optimum utilisation of regulatory resources – Ease of Regulation and Interconnection
140 Challenges to Convergence…1
• Migration to converged license regime
• Technical Standards
• Fair and non-discriminatory access
• Competition Issues
• Frequency Spectrum
• USO and Digital Divide
141 Challenges to Convergence…2
1. Migration to converged licensing regime:
– Maintenance of Level Playing Filed between existing and new players – Service based licenses with heterogenous terms and conditions of licenses – The existing service provider may need multiple licenses to provide services – Licence mapping for all current licenses from old to new licence categories – License transitions process – Licence structure design and drafting
142 Challenges to Convergence…3
2. Technical standards: – Standards supporting convergence still evolving
– Availability of multiple standards by different agencies (ITU, IETF, ETSI, ANSI, IEEE etc)
– Problems of inter-working between various standards
– Standards for Quality of Service not yet matured
– Need for Technology Neutral Regulations
143 Challenges to Convergence…4
3. Fair and non-discriminatory access :
– Complex Regulations governing access to bottleneck facilities
– Transparent , Non- discriminatory &Cost based access.
– Access to contents: Program access regime
144 Challenges to Convergence…5
4. Competition Issues
– Removal of industry specific regulations and its replacement with general competition law applied equally to all industries.
– Legal framework aiming at promoting competition and prohibiting a range of anti-competitive practices including: – Anti-competitive Agreements; – Anti-competitive mergers ;and – Misuse of market power
– Cross-boarder mergers and cross- media ownership restrictions in certain parts of the media
– Foreclosure of markets by anti- competitive conduct 145 Challenges to Convergence…6
5. Frequency Spectrum:
– Possible reallocation of frequency spectrum.
– Optimum allocation of spectrum to the new licensees.
– No precedence for allocation of the spectrum in the new regime.
– De-licensing of bands for certain applications.
146 Challenges to Convergence…7
6. Universal Service Obligations and bridging the Digital Divide
– Redefining the scope of Universal Service
– Identifying contributors for USO
– Formulation of regulatory policy to bridge the Digital Divide
147 Licensing under Convergence
• Purpose
– Authorise market players to do business
– Prescribe the rights and obligations of market players
• Forms
– Concessions – contractual arrangement between governments and operators
– Licences – unilateral act on the part of the licensing authority (preferred method in SA)
148 Types of Licenses
• Individual licences
• Class licences
• Licence exemptions
149 Individual licenses
• Often limited competition licences – used where market entry is restricted for policy reasons (eg because a limit has been placed on facilities-based competition) or for technical reasons (eg spectrum scarcity)
• Even in countries where competition is not restricted, individual licences may be used to impose special licence conditions on particular operators to ensure that they behave in a particular manner (eg where an operator has significant market power)
• Usually granted pursuant to some form of comparative selection process
• Preferred licensing method in South Africa
150 Class licenses
• Issued without any selection process
• Useful tool for simplifying the authorisation regime where there is no limit on the number of market entrants
• Class licences are generally employed where individual licences are not justified, but where there are significant regulatory objectives that can be achieved by establishing general conditions (eg consumer protection requirements
• Mainly used in countries that have fairly deregulated telecom sectors
• Not used in South Africa (yet)
151 Class licences
• Issued without any selection process
• Useful tool for simplifying the authorisation regime where there is no limit on the number of market entrants
• Class licences are generally employed where individual licences are not justified, but where there are significant regulatory objectives that can be achieved by establishing general conditions (eg consumer protection requirements
• Mainly used in countries that have fairly deregulated telecom sectors
• Not used in South Africa (yet) 152 Licence exemptions
• Generally granted in respect of service categories that are fully liberalised
• Useful tool in highly deregulated markets where an activity is technically caught within the definition of activities subject to regulation (eg offering a telecom service to the public), but where no justification exists for imposing any licensing requirements
• General requirements (eg registration with the regulator) tend to be imposed via general regulations and orders
• In South Africa, all telecom service providers are required to hold a licence, but ICASA is empowered to grant exemptions in respect certain service categories
153 Methods for choosing new entrants
• Competitive selection – Based on a single objective quantitative criterion – Usually used to allocate spectrum, not for service licences – Transparent, but can be costly
• Comparative selection – Based on a quasi-subjective assessment of one or more quantitative selection criteria – Not transparent – prone to accusations of bias and corruption from losing bidders – Currently the preferred method in SA for limited competition licences 154 Licensing trends
• General shift away from individual / comparative selection processes to class-based licensing systems for facilities-based competition (EU)
• Removal of all restrictions on the number of service- based and facilities-based competitors (most developed markets)
• Adoption of class licensing regime / granting of licence exemptions for service providers and content providers (Australia / Far East)
155 Convergence and licensing
• Convergence is usually coupled with deregulation and liberalisation of the licensing regime
• Usually, more stringent licensing requirements apply to network services / facilities
• Application services / content services are often subject to comparatively light touch regulation, and sometimes exempted from the requirement to hold a licence altogether
156 Licensing in Malaysia (1)
• Four-tiered regulatory regime for telecoms
– Network facilities providers – owners of communications networks
– Network service providers – provide the basic connectivity and bandwidth. Network service providers are typically also the owners of network facilities
– Applications service providers – provide particular functions to end users (such as voice services, data services, content-services, and e-commerce services)
– Content applications service providers – are a special subset of application services. Content services include traditional broadcast services and new services such as online publishing and information
157 services Licensing in Malaysia (2)
Category Individual licence Class licence Exempt Network facility Earth stations, fixed links & cables, Niche or limited purpose Broadcasting & production providers public payphone facilities, network facilities studios, incidental network radiocommunications transmitters facilities, private network and links, satellites, submarine facilities cables, switching centres Network service Bandwidth services, broadcasting Niche customer access Incidental network services, providers distribution services, cellular mobile services, niche connection LAN services, private network services, access applications services services, routers, services internetworking

Content Satellite broadcasting subscription Not issued Internet content applications applications services, broadcasting, terrestrial free services service to air TV, terrestrial radio providers broadcasting
158 Licensing in Australia
• Open telecommunications market
• Three-tiered regulatory regime for telecoms:
– Carrier licences – subject to individual licensing, but no restriction on the number of facilities-based competitors
– Carrier service providers – exempt from the requirement to be licensed
– Content service providers – exempt from the requirement to be licensed
159 Comparison: Australia / Malaysia
• Australia applies uniform licensing rules to each tier (networking / services / content)
– Less intensive and complex to administer
– Only appropriate in a highly deregulated market (?)
• Malaysia applies different licensing rules to service categories within each tier, depending on their economic importance
– More complex and intensive to administer
– More appropriate in an environment of managed liberalisation such as South Africa (?)
160 Licensing regime in SA (1)
• Telecommunications – The Telecommunications Act does not take a tiered approach to licensing
– Facilities and application services are both treated as telecom services
– The Telecommunications Act does not deal with the transmission of content over telecom networks – this is self regulated between network operators and service providers
• Broadcasting – The broadcasting legislation distinguishes between broadcasting (content), signal distribution and multi-channel distribution – there is some attempt to tier the licensing regime 161 Licensing regime in SA (2)
• Broadcasting and telecoms are subject to different licensing requirements in SA
• In general, the licensing regime for broadcasting is far less restrictive and is subject to less executive interference than in the case of telecoms
• Eg: facilities-provisioning in the telecoms environment is restricted, whereas in broadcasting, anyone may self-provide, provided that a signal distribution licence is obtained
• Will the harmonisation of licensing regimes result in telecoms being deregulated to the broadcasting 162 standard? Convergence in South Africa
Telkom’s position Telkom’s Key Principles on Convergence • Managed liberalisation
• Clear Regulatory Environment
• Effective & Independent Regulator
• Self-regulation & Co-regulation
• Technology-neutral
• Fair & Balanced outcomes
• Consultative & Public process 164 Convergence Colloquium
• Telkom welcome convergence and has participated fully at the industry Colloquium on Convergence
• Draft 1 of the Convergence Bill was released to the industry for comment on 25 July 2003
• Thereafter industry was involved in an extensive process of effectively redrafting the Bill • The industry wants one piece of legislation that will replace the existing legislation governing ICASA and the telecoms and broadcasting industries – the DoC does not want to repeal the underlying legislation
• The redrafted Bill raised more questions than answers – effectively taking it back to the drawing board for further redrafting
• Redrafted Bill expected to be tabled in Parliament towards the end of 2004 165 Convergence Colloquium
• Convergence regulation in most countries post-dates the liberalisation of the market
• What is unusual about South Africa is that convergence regulation is taking place in a context of managed liberalisation – the market has not yet been fully opened up to competition
• Real purpose of the Bill is to pave the way for market liberalisation

169 The Bill so far… (1)
• Licensing regime
– 3 tier horizontal licensing regime • Network services • Application services • Content services
– 3 types of licensing methods • Individual • Class • exemptions
170 The Bill so far… (2)
• Transitional provisions
– All existing licences to remain valid for their full duration
– ICASA must convert current vertical licences to horizontal licences with the agreement of each licensee
– All existing network operators to be confined to their vertical markets for 2 years, after which they may compete across each others’ platforms (affects Cell C, MTN, Orbicom, Sentech, SNO, Telkom & Vodacom) 171 The Bill so far… (3)
• Clarification of the roles of the Minister and the regulator
– Gives ICASA full responsibility for regulatory processes
– Relegates the role of the Minister to policy- making only
– Main impact: gives ICASA independence in relation to licensing and regulation-making
172 The Bill so far… (4)
• Competition issues
– The Bill reinforces ICASA’s concurrent jurisdiction with the Competition Commission over general competition matters
– ICASA retains exclusive jurisdiction over sector specific competition matters (such as access, interconnection, facilities leasing, number portability, carrier pre-selection, etc)
173 Concluding remarks
• Technology changes quickly, regulations change slowly
• Legacy regulation is not relevant in the convergence era
• Prioritisation of regulatory challenges for optimum utilisation of regulatory resources
• Drawing the roadmap for implementation of convergence
• Need for efficient and timely dispute resolution mechanisms for converged licensing regime
• Capacity and expertise building in the regulatory bodies to meet the challenges of convergence 174 Question and Answer Session
