V INTRODUCCION El presente desarrollo de tesis da cuenta de la investigación llevada a cabo en torno a IMT-2000 y sus implicancias en el futuro de la telefonía móvil en Chile. IMT-2000 es un estándar desarrollado por la Unión Internacional de Telecomunicaciones (UIT) que abarca aspectos tecnológicos de redes móviles y de los servicios que estas ofrecen. IMT-2000 congrega en un solo estándar las ventajas asociadas a la red Internet y a la naturaleza de las comunicaciones móviles, para brindar una nueva generación de servicios móviles que se espera apoyen al desarrollo de las economías de los países que adopten este sistema y a llevar a los usuarios hacia una nueva era de la sociedad de la información digital, esta vez mediante un terminal móvil. Motivan esta investigación el creciente interés que ha suscitado IMT-2000 en el mercado de las comunicaciones móviles, producto del advenimiento de los servicios basados en tecnología de Internet y el espectacular crecimiento a escala global de los usuarios de Internet y de teléfonos móviles. Estos servicios ya están comenzando a ser implementados en los países más industrializados del mundo, como Japón, Corea y China, y en algunos países de Europa. No obstante lo anterior, hay varias incógnitas que deben resolverse a fin que el mercado 3G tenga un real éxito comercial. Estas incógnitas dicen relación con la capacidad que tengan los mercados locales de adoptar nuevos y revolucionarios servicios y en cómo los operadores de redes móviles deban enfrentar los desafíos comerciales y tecnológicos que se avecinan con el advenimiento de nuevas tecnologías, de modo que el negocio siga siendo rentable y sustentable en el tiempo. Chile no está ajeno a esta realidad y resulta conveniente conocer en qué consisten estas nuevas tecnologías, su ámbito de competencia, los riesgos involucrados en su adopción, e identificar los aspectos que deban tomarse en consideración para cuando estas redes hagan su aparición en Chile. El presente trabajo de tesis se enfoca principalmente a analizar el estándar IMT-2000 y su realidad actual en el marco de comunicaciones móviles 2G, y proyectar la evolución de los operadores 2G hacia 3G en aspectos comerciales y técnicos pensando en su implementación en Chile. VI OBJETIVOS El presente trabajo de tesis persigue los siguiente objetivos generales: § Conocer el estado del arte de las comunicaciones móviles, tanto en el ámbito nacional como internacional considerando aspectos de mercado, tecnológicos, servicios, aplicaciones, etc. § Conocer las características de los futuros sistemas 3G o IMT-2000. § Conocer las tecnologías a optar para evolucionar a IMT-2000 sobre las redes existentes. § Analizar la posibilidad de implementar sistemas 3G en Chile, a corto y mediano plazo, desde un punto de vista tecnológico, de mercado, y regulatorio. § Análisis del mercado para servicios de tercera generación, y su introducción al mercado (análisis temporal). METODO DE TRABAJO No obstante que el tema de tesis se refiere a comunicaciones móviles globales, el desarrollo del documento se basará esencialmente en comunicaciones móviles terrestres. El estudio de los servicios 3G en cuestión y su implementación al mercado requiere de análisis de mercado más desarrollados, los que tampoco están dentro de los objetivos. Sin embargo se describirán las características principales y los segmentos de mercado a los cuales apuntan. Durante el desarrollo del documento se observarán muchos términos técnicos que probablemente sean ajenos al conocimiento del lector. Se recomienda revisar los documentos anexos y remitirse a la bibliografía y a las referencias especificas. VII Método de trabajo El método de trabajo se basó fundamentalmente en la recopilación de información proveniente de la industria de las telecomunicaciones, como son empresas operadoras de sistemas de comunicaciones móviles, organismos de estandarización, proveedores de infraestructura de telecomunicaciones, foros de la industria, e información aparecida en la prensa tanto nacional como internacional. Destacar que la consulta de esta información fue realizada exclusivamente a través de la red Internet. La información recopilada fue almacenada y clasificada según su ámbito de competencia. En los casos de los textos estaban escritos en otros idiomas, especialmente el inglés, se realizaron las traducciones de idioma respectivas. Posteriormente se realizó una crítica de la información y se elaboró un documento con las bases teóricas de las comunicaciones móviles, de su estado del arte, del estándar IMT-2000 y las tecnologías involucradas. Finalmente se desarrolló un análisis a la información obtenida respecto del mercado chileno de telefonía móvil, del marco regulatorio, y se relacionó dicha información con los aspectos tecnológicos investigados para indicar las conclusiones obtenidas en torno a la implementación de IMT-2000 en Chile.

  • Mixed Messages from Mexico
    REGULATION MIXED MESSAGES FROM MEXICO There has been rapid progress in more affordable telecoms access and wider coverage in Mexico, but the view of ADRIAAN TEN KATE is that reforms – aimed mainly at establishing equal access at competitive prices – may fail to address current and future convergence and technology challenges he Mexican telecoms reforms of 2013 and 2014 mate in the mobile market, Telcel, had acquired a were inspired by a dubious perception that comfortable share of 70%. As of 2010, the new Mexican telecoms were lagging far behind entrants in fixed telephony Alestra (AT&T) and T modern developments, by an excessive Avantel (Sprint), had bitten the dust, and confidence in what competition can bring about in competition was coming from TV cable operators markets with strong economies of scale and by entering the triple-play market. In mobile, Telcel, unrealistic expectations about what economic taking advantage of its relations with Telmex, had regulation can achieve in such a setting. As I set out quickly overtaken the initial operator, Iusacell, in this article, the results thus far are a crusade while its main competitor Movistar (Telefónica) had against the incumbents under the banner of never been able to get much more than 20% of the competition, a spiral of regulatory intervention market (although Telcel is not the incumbent in the with increasing costs and diminishing returns, and mobile market in the strict sense of the word, I refer a creeping erosion of the incentives that private to it as such for simplicity). operators are left with to invest in the expansion Cofetel blamed this on the anticompetitive and upgrading of their networks.

Market developments in telecommunication and broadcasting in Mexico This chapter reviews changes in the telecommunication and broadcasting sectors in Mexico as well as market developments, particularly since the 2013 reform. It reviews market performance, market participation and the competitive environment in both the telecommunication and broadcasting sectors and concludes with developments in convergence. The statistical data for Israel are supplied by and under the responsibility of the relevant Israeli authorities. The use of such data by the OECD is without prejudice to the status of the Golan Heights, East Jerusalem and Israeli settlements in the West Bank under the terms of international law. OECD TELECOMMUNICATION AND BROADCASTING REVIEW OF MEXICO 2017 © OECD 2017 80 – 2. MARKET DEVELOPMENTS IN TELECOMMUNICATION AND BROADCASTING IN MEXICO Five years after the OECD Review of Telecommunication Policy and Regulation in Mexico (OECD, 2012), and four years after the reform in the area was initiated, substantial changes can be observed in the Mexican telecommunication and broadcasting markets. The number of people with a mobile broadband subscription, for example, increased from 24 million in 2012 to over 74 million in 2016. Prices have decreased for mobile telecommunication services. Significant growth in revenues in the telecommunication and broadcasting sectors can be observed and foreign investors have entered the telecommunication and satellite markets. The availability of spectrum for mobile services has improved and is expected to increase further in the coming two years. Investment in telecommunication increased and the Red Compartida – a shared wholesale wireless network with Long-term Evolution (LTE) mobile telecommunication technology (also known as “4G” fourth-generation) – will likely continue to spur investments in the mobile market.

However, in the years that followed, a number of obstacles to competition and the development of telecommunications were identified. As a result, a constitutional reform was implemented in 2013. It consisted of a series of measures that have contributed to shape the sector as it is nowadays, with favourable outcomes that have begun to be tangible. This article recounts the evolution and current state of the Mexican telecommunications ecosystem, briefly describing new challenges and opportunities posed by the digital economy. Introduction: overview of the current situation In recent years the telecommunications sector in Mexico has been characterised by a transition toward conditions of effective competition, mainly due to recent measures taken by the authorities.

The Economic Competition Federal Law marked Mexico’s most radical move yet to revamp its telecommunications institutional framework, fight vested interests, and change the competitive landscape in hopes to boost investment and improve services. This report evaluates the Federal Telecommunications Institute (IFT) policy decisions and looks at market indicators in the fixed and mobile markets to assess change. The IFT has had important institutional wins effectively implementing most asymmetric regulations. The courts have upheld its decisions, and –amid some controversy– selected a winner for the 700MHz band PPP contract.

Policy and regulation in telecommunication and broadcasting in Mexico This chapter examines the design of regulation and policies of the telecommunication and broadcasting sectors in Mexico, most of which have been introduced since the 2013 reform, based on the changes to the legal framework discussed in Chapter 3. It covers issues such as wholesale and retail regulation, digital inclusion strategies, competition aspects and enforcement as well as consumer protection and empowerment. It also reviews the second round of asymmetric measures imposed on the preponderant agents announced by the Federal Telecommunications Institute (Instituto Federal de Telecomunicaciones, IFT) in March 2017. OECD TELECOMMUNICATION AND BROADCASTING REVIEW OF MEXICO 2017 © OECD 2017 150 – 4. POLICY AND REGULATION IN TELECOMMUNICATION AND BROADCASTING IN MEXICO Wholesale regulation The regulatory framework in Mexico has undergone a substantial transformation since the 2012 OECD Review of Telecommunication Policy and Regulation in Mexico. It distinguishes preponderant agents and agents with substantial market power (SMP) from other operators, such as concessionaires or entities, which have been authorised to provide telecommunication services (e.g. mobile virtual network operators, MVNOs). Since the reform, the Federal Telecommunications Institute (Instituto Federal de Telecomunicaciones, IFT) has declared América Móvil in telecommunication services and the Televisa Group in broadcasting as preponderant and has imposed asymmetric measures upon them. In February 2017, the IFT further determined that the Televisa Group also had SMP in telecommunication services due to its position in pay TV, which is considered part of the telecommunication market. However, thus far, the IFT has not imposed asymmetric measures on Televisa for pay TV.
