Análisis prospectivo del despliegue de redes de comunicaciones móviles LTE en nuevas bandas de frecuencia mediante el desarrollo de modelos tecnoeconómicos

El estándar LTE se ha posicionado como una de las claves para que los operadores de telecomunicación puedan abordar de manera eficiente en costes el crecimiento de la demanda de tráfico móvil que se prevé para los próximos años, al ser una tecnología más escalable en el núcleo de la red y más flexible en la interfaz radio que sus predecesoras. En este sentido, es necesario también que los reguladores garanticen un acceso al espectro radioeléctrico adecuado, equitativo y no discriminatorio, que permita un entorno estable para el despliegue de redes de comunicaciones móviles avanzadas. Además de la flexibilización del marco regulador del espectro radioeléctrico en Europa, que ha permitido el despliegue de nuevas tecnologías en las bandas de frecuencia históricas de GSM, se ha puesto a disposición espectro adicional para sistemas IMT en nuevas bandas de frecuencia, lo que ha planteando a su vez nuevos retos para la tecnología y la regulación. La fragmentación del espectro disponible para comunicaciones móviles ha impulsado el desarrollo de técnicas de agregación de portadoras en las nuevas versiones del estándar LTE, que permiten explotar mejor los recursos radio en su conjunto. No obstante, el espectro inferior a 1 GHz sigue siendo escaso, ya que el tráfico móvil aumenta y la banda de 900 MHz aún se utiliza para servicios GSM, lo que no ha conseguido sino agravar la disputa entre los servicios de radiodifusión terrestre y de comunicaciones móviles por la parte superior de la banda UHF. En concreto, la banda de 700 MHz se perfila como una de las próximas para aumentar el espectro disponible para los servicios en movilidad, si bien su liberación por parte de las actuales redes de Televisión Digital Terrestre presenta no pocas dificultades en los Estados miembros en los que ésta es la principal plataforma audiovisual de acceso gratuito, abriendo un debate sobre el modelo audiovisual a largo plazo en Europa. Por otro lado, las políticas públicas de promoción del acceso a la banda ancha rápida y ultrarrápida de la presente década han establecido objetivos ambiciosos para el año 2020, tanto en el ámbito europeo como en los diferentes Estados miembros. La universalización del acceso a redes de banda ancha de al menos 30 Mbps constituye uno de los principales retos. Las expectativas generadas por la tecnología LTE y la puesta a disposición de nuevas bandas de frecuencia hace posible que los servicios de acceso fijo inalámbrico adquieran especial relevancia ante los objetivos de política pública establecidos que, como ha sido reconocido en diversas ocasiones, no podrán lograrse sino con un compendio de diferente tecnologías. Para esta Tesis Doctoral se han desarrollado una serie modelos tecnoeconómicos con el objetivo de realizar un análisis prospectivo que evalúa tres casos de especial relevancia en el despliegue de redes LTE: en primer lugar, la valoración económica de la banda de 700 MHz; en segundo lugar, la evaluación de modelos de negocio y reducción de costes considerando tecnologías femtocelulares; y finalmente, la viabilidad de las redes LTE de acceso fijo inalámbrico para el cierre de la brecha digital en el acceso a la banda ancha de 30 Mbps. En relación con la aplicación del análisis tecnoeconómico para la valoración del espectro de 700 MHz, los resultados obtenidos ponen de manifiesto dos cuestiones fundamentales. En primer lugar, la necesidad de asignar a los operadores más espectro para satisfacer las previsiones de demanda de tráfico móvil a medio plazo. En segundo, existe una diferencia notable en los costes de despliegue de una red LTE cuando se dispone de espectro en frecuencias inferiores a 1 GHz y cuando no, pero esta diferencia de costes disminuye a medida que se añade nuevo espectro sub-1GHz. De esta manera, la atribución de la banda de 700 MHz a servicios de comunicaciones móviles supone una reducción relevante en los costes de despliegue si el operador no dispone de espectro en la banda de 800 MHz, pero no así si ya dispone de espectro en bandas bajas para el despliegue. En este sentido, puede concluirse que el precio que los operadores estarán dispuestos a pagar por el espectro de la banda de 700 MHz dependerá de si ya tienen disponible espectro en la banda de 800 MHz. Sin embargo, dado que la competencia por ese espectro será menor, los ingresos esperables en las licitaciones de esta nueva banda serán en general menores, a pesar de que para algunos operadores este espectro sería tan valioso como el de 800 MHz. En segundo lugar, en relación con el despliegue de femtoceldas pueden extraerse algunas conclusiones en términos de ahorro de costes de despliegue y también de cara a la viabilidad de los modelos de negocio que posibilitan. El ahorro que supone la introducción de femtoceldas en el despliegue de una red LTE frente al caso de un despliegue exclusivamente macrocelular se ha demostrado que es mayor cuanto menor es el ancho de banda disponible para la red macrocelular. En esta línea, para un operador convergente el despliegue de femtoceldas tiene sentido económico si el ancho de banda disponible es escaso (en torno a 2x10 MHz), que, en el caso de España, puede reflejar el caso de los operadores del segmento fijo que son nuevos entrantes en el móvil. Por otro lado, los modelos de acceso abierto son interesantes para operadores exclusivamente móviles, porque consiguen flexibilizar los costes sustituyendo estaciones base macrocelulares por el despliegue de femtoceldas, pero necesitan desplegarse en zonas con una densidad de población relativamente elevada para que éstas descarguen tráfico de varios usuarios de la red macrocelular simultáneamente. No obstante, las femtoceldas son beneficiosas en todo caso si es el usuario quien asume los costes de la femtocelda y el backhaul, lo que sólo parece probable si se integran en el modelo de negocio de comercialización de nuevos servicios. Por tanto, el despliegue de femtoceldas en buena parte de la casuística estudiada sólo tiene sentido si consiguen aumentar los ingresos por usuario comercializando servicios de valor añadido que necesiten calidad de servicio garantizada y exploten a la vez de esa forma su principal ventaja competitiva respecto a la tecnología WiFi. Finalmente, en relación con el papel de la tecnología LTE para la provisión de servicios de acceso fijo inalámbrico para la banda ancha de 30 Mbps, se ha desarrollado un modelo TD-LTE y mediante la metodología de análisis tecnoeconómico se ha realizado un estudio prospectivo para el caso de España. Los resultados obtenidos preciden una huella de cobertura de FTTH del 74% para 2020, y demuestran que una red TD-LTE en la banda de 3,5 GHz resulta viable para aumentar la cobertura de servicios de 30 Mbps en 14 puntos porcentuales. Junto con la consideración de la cobertura de otras redes, la cobertura de 30 Mbps de acuerdo a la viabilidad de los despliegues alcanzaría el 95% en España en el año 2020. Como resumen, los resultados obtenidos muestran en todos los casos la capacidad de la tecnología LTE para afrontar nuevos desafíos en relación con el aumento del tráfico móvil, especialmente crítico en las zonas más urbanas, y el cierre de la brecha digital en el acceso a la banda ancha rápida en las zonas más rurales. ABSTRACT The LTE standard has been pointed out as one of the keys for telecom operators to address the demand growth in mobile traffic foreseen for the next years in a cost-efficient way, since its core network is more scalable and its radio interface more flexible than those of its predecessor technologies. On the other hand, regulators need to guarantee an adequate, equitable and non-discriminatory access to radio spectrum, which enable a favorable environment for the deployment of advanced mobile communication networks. Despite the reform of the spectrum regulatory framework in Europe, which allowed for the deployment of new technologies in the historic GSM bands, additional spectrum has been allocated to IMT systems in new frequency bands, what in turn has set out new challenges for technology and regulation. The current fragmentation of available spectrum in very different frequency bands has boosted the development of carrier aggregation techniques in most recent releases of the LTE standard, which permit a better exploitation of radio resources as a whole. Nonetheless, spectrum below 1 GHz is still scarce for mobile networks, since mobile traffic increases at a more rapid pace than spectral efficiency and spectrum resources. The 900 MHz frequency band is still being used for GSM services, what has worsen the dispute between mobile communication services and terrestrial broadcasting services for the upper part of the UHF band. Concretely, the 700 MHz frequency band has been pointed out as one of the next bands to be allocated to mobile in order to increase available spectrum. However, its release by current Digital Terrestrial Television networks is challenging in Member States where it constitutes the main free access audiovisual platform, opening up a new debate around the audiovisual model in the long term in Europe. On the other hand, public policies of the present decade to promote fast and ultrafast broadband access has established very ambitious objectives for the year 2020, both at European and national levels. Universalization of 30 Mbps broadband access networks constitutes one of the main challenges. Expectations raised by LTE technology and the allocation of new frequency bands has lead fixed wireless access (FWA) services to acquire special relevance in light of public policy objectives, which will not be met but with a compendium of different technologies, as different involved stakeholders have acknowledged. This PhD Dissertation develops techno-economic models to carry out a prospective analysis for three cases of special relevance in LTE networks’ deployment: the spectrum pricing of the 700 MHz frequency band, an assessment of new business models and cost reduction considering femtocell technologies, and the feasibility of LTE fixed wireless access networks to close the 30 Mbps broadband access gap in rural areas. In the first place and regarding the application of techno-economic analysis for 700 MHz spectrum pricing, obtained results reveal two core issues. First of all, the need to allocate more spectrum for operators in order to fulfill mobile traffic demand in the mid-term. Secondly, there is a substantial difference in deployment costs for a LTE network when there is sub-1GHz spectrum available and when there is not, but this difference decreases as additional sub-1GHz spectrum is added. Thus, the allocation of 700 MHz band to mobile communication services would cause a relevant reduction in deployment costs if the operator does not count on spectrum in the 800 MHz, but not if it already has been assigned spectrum in low frequencies for the deployment. In this regard, the price operators will be willing to pay for 700 MHz spectrum will depend on them having already spectrum in the 800 MHz frequency band or not. However, since competition for the new spectrum will not be so strong, expected incomes from 700 MHz spectrum awards will be generally lower than those from the digital dividend, despite this spectrum being as valuable as 800 MHz spectrum for some operators. In the second place, regarding femtocell deployment, some conclusions can be drawn in terms of deployment cost savings and also with reference to the business model they enable. Savings provided by a joint macro-femto LTE network as compared to an exclusively macrocellular deployment increase as the available bandwidth for the macrocells decreases. Therefore, for a convergent operator the deployment of femtocells can only have economic sense if the available bandwidth is scarce (around 2x10 MHz), which might be the case of fix market operators which are new entrant in mobile market. Besides, open access models are interesting for exclusively mobile operators, since they make costs more flexible by substituting macrocell base stations by femtocells, but they need to be deployed relatively densely populated areas so that they can offload traffic from several macrocell users simultaneously. Nonetheless, femtocells are beneficial in all cases if the user assumes both femtocell and backhaul costs, which only seems probable if they are integrated in a business model commercializing new services. Therefore, in many of the cases analyzed femtocell deployment only makes sense if they increase revenues per user through new added value services which need from guaranteed quality of service, thus exploiting its main competitive advantage compared to WiFi. Finally, regarding the role of LTE technology in the provision of fixed wireless access services for 30 Mbps broadband, a TD-LTE model has been developed and a prospective study has been carried out through techno-economic methodology for the Spanish case. Obtained results foresee a FTTH coverage footprint of 74% households for 2020, and prove that a TD-LTE network in the 3.5 GHz band results feasible to increase 30 Mbps service coverage in additional 14 percentage points. To sum up, obtained results show LTE technology capability to address new challenges regarding both mobile traffic growth, particularly critical in urban zones, and the current digital divide in fast broadband access in most rural zones.

O \"si\" da técnica psicanalítica: uma análise institucional do discurso de O mal-estar na civilização

Partindo das considerações de que os termos sujeito e subjetividade permeiam o discurso psicanalítico contemporâneo e de que são, direta e indiretamente, atribuídos a Freud a despeito de ele próprio nunca tê-los conceituado, esta pesquisa tem como objetivo caracterizar um perfil de sujeito a partir do discurso freudiano. O trabalho orientou-se pela metodologia da Análise Institucional do Discurso, uma analítica do domínio subjetivo que toma o discurso em seu caráter de ato e acontecimento. Primeiramente se realizou um estudo de As técnicas de si, de Michel Foucault, de modo a permitir o circunstanciamento da psicanálise como uma técnica que produz um si, um sujeito este circunstanciamento permitiu, então, tomar sujeito e subjetividade na qualidade de produções histórica, geográfica e analiticamente contextualizadas, não como formas de imanência ou transcendência. A partir desse pressuposto, elaborou-se uma análise institucional do discurso de O mal-estar na civilização que privilegiou não apenas seu conteúdo, mas principalmente seu modo de produção, colocando em relevo o contexto presente no texto, as interlocuções que se criam, os lugares atribuídos e ocupados, as expectativas assim mobilizadas, as estratégias discursivas utilizadas, os jogos de poder e verdade exercidos, bem como os efeitos de reconhecimento e desconhecimento então facultados. Esta análise mostrou que Freud exerce uma perspectiva de interioridade, pois o mal-estar que acomete a civilização é compreendido em analogia à concepção psicanalítica de desenvolvimento individual, explicando, em suma, a cultura pelo prisma do indivíduo; evidenciou que as teorizações sobre a vida instintiva são a principal sustentação do discurso sobre o mal-estar da civilização; apontou como as estratégias discursivas utilizadas por Freud promovem a subjetivação, por parte do leitor, daquilo que seu discurso produz como verdade; e que o conceito de indivíduo é ocasião de exercício daquela perspectiva de interioridade e de atualização dos pressupostos teóricos. Com base nisso, pôde-se caracterizar um sujeito universal; psicologizado; determinado sobretudo pelos movimentos da sexualidade e da agressividade; cuja tônica recai sobre o dito mundo interno; dotado de origens e propósitos concernentes à vida instintiva; e cujo perfil é delimitado pela tarefa de administração dos instintos, isto é, cujo perfil se dá entre os imperativos superegóicos de renúncia e a margem de liberdade de que dispõe para satisfazer as exigências do princípio de prazer. Observou-se também, na esteira do pontuado por Guirado (2010), que em geral Freud naturaliza os termos do discurso teórico, fazendo de sua universalização a condição e o limite para se pensar o domínio subjetivo e a singularidade; diferentemente de Foucault, que compreende esse domínio em referência às relações de poder e saber, de forma contextualizada. Do ponto de vista da análise institucional do discurso freudiano, concluiu-se, finalmente, que o si ao qual a técnica psicanalítica dá lastro é efeito da perspectiva exercida por Freud, que promove o reconhecimento da interioridade instintiva como crivo da civilização, de um modo de vida e de si mesmo

Health inequality between immigrants and natives in Spain: the loss of the healthy immigrant effect in times of economic crisis

Background: The immigrant population living in Spain grew exponentially in the early 2000s but has been particularly affected by the economic crisis. This study aims to analyse health inequalities between immigrants born in middle- or low-income countries and natives in Spain, in 2006 and 2012, taking into account gender, year of arrival and socioeconomic exposures. Methods: Study of trends using two cross-sections, the 2006 and 2012 editions of the Spanish National Health Survey, including residents in Spain aged 15–64 years (20 810 natives and 2950 immigrants in 2006, 14 291 natives and 2448 immigrants in 2012). Fair/poor self-rated health, poor mental health (GHQ-12 > 2), chronic activity limitation and use of psychotropic drugs were compared between natives and immigrants who arrived in Spain before 2006, adjusting robust Poisson regression models for age and socioeconomic variables to obtain prevalence ratios (PR) and 95% confidence interval (CI). Results: Inequalities in poor self-rated health between immigrants and natives tend to increase among women (age-adjusted PR2006 = 1.39; 95% CI: 1.24–1.56, PR2012 = 1.56; 95% CI: 1.33–1.82). Among men, there is a new onset of inequalities in poor mental health (PR2006 = 1.10; 95% CI: 0.86–1.40, PR2012 = 1.34; 95% CI: 1.06–1.69) and an equalization of the previously lower use of psychotropic drugs (PR2006 = 0.22; 95% CI: 0.11–0.43, PR2012 = 1.20; 95% CI: 0.73–2.01). Conclusions: Between 2006 and 2012, immigrants who arrived in Spain before 2006 appeared to worsen their health status when compared with natives. The loss of the healthy immigrant effect in the context of a worse impact of the economic crisis on immigrants appears as potential explanation. Employment, social protection and re-universalization of healthcare would prevent further deterioration of immigrants’ health status.

The radical Islamic militants of Central Asia. OSW Report, November 2013

Radical Islamic militants from Central Asia have ceased to be a local phenomenon. The organisations created by those groups (the Islamic Movement of Uzbekistan and the Islamic Jihad Union) engage in propaganda, recruitment, fundraising and terrorist operations in states distant from their traditional area of interest, such as European Union countries, South Asia and the United States. Their ranks contain not only Central Asian Islamists, but also those from other countries, such as Russia, Pakistan, Germany, France, the United Kingdom, China, Turkey and even Myanmar. These organisations’ current activities and forms are multidimensional and complicated, characterised by combat versatility, structural amorphism, operational mobility and simultaneous operations in different fields and theatres. As a result of the universalization of Islamic terrorism, these organisations have been intensifying contacts with other international Islamic terrorist organisations based in Waziristan (mainly al-Qaida, Taliban and the Haqqani Network). A specific system of mutual cooperation has developed between them, involving the specialisation of various terrorist organisations in particular aspects of terrorist activity. The IMU and IJU specialise in the recruitment and training of Islamic radicals from around the world, and have thus become a kind of ‘jihad academy’.

Universalização do acesso à saúde e regulação dos planos privados de assistência à saúde: a atuação regulatória da ANS como instrumento de harmonia contratual e viabilização do papel suplementar da iniciativa privada na efetivação do direito social à saúde

While essential to human nature, health and life have been protected since ancient times by various areas of knowledge, particularly by the Law, given its dynamics within the regulation of social interactions. In Brazil, health has been granted major importance by the Federal Constitution of 1988, which, disrupting the dictatorial authoritarianism, inaugurating a Social State and focusing on the values of freedom and human dignity, raises health to the condition of a social right, marked predominantly by an obligational bias directed, primarily, to the State, through the enforcement of public policies. Although, given the limitation of the State action to the reserve for contingencies, it turns clear that an universalizing access to public health is impossible, seen that the high cost of medical provisions hinders the State to meet all the health needs of the rightholders. As a result of the inefficiency of the State, the effort of the Constituent Assembly of 1988 in creating a hybrid health system becomes nuclear, which, marked by the possibility of exploration of healthcare by the private initiative, assigns to the private enterprise a key role in supplementing the public health system, especially through the offer of health insurance plans. At this point, however, it becomes clear that health provisions rendered by the private agents are not unlimited, which involves discussions about services and procedures that should be excluded from the contractual coverage, for purposes of sectoral balance, situation which draws the indispensability of deliberations between Fundamental Rights on one hand, related to the protection of health and life, and contractual principles on the other hand, connected to the primacy of private autonomy. At this point, the importance of the regulation undertaken by the ANS, Brazilian National Health Agency, appears primordial, which, by means of its seized broad functions, considerable autonomy and technical discretion, has conditions to implement an effective control towards the harmonization of the regulatory triangle, the stability and development of the supplementary health system and, consequently, towards the universalization of the right to health, within constitutional contours. According to this, the present essay, resorting to a broad legislative, doctrinal and jurisprudential study, concludes that economic regulation over the private healthcare sector, when legitimately undertaken, provides progress and stability to the intervening segment and, besides, turns healthcare universalization feasible, in a way that it can not be replaced efficiently by any other State function.

A regionalização como instrumento de governança pública em saúde no estado do Paraná: análise dos vazios assistenciais como subsídio à ação do estado

Everyone has a right to health and the State’s duty is to provide it. SUS (unified health system) main principles are universalization, integrality and equality which are based on the decentralization, regionalization and hierarchization directives and shows the importance of a territorial perspective for planning healthcare actions. Decentralization was the strategy chosen to implant SUS, since municipalities were in charge of providing and organizing the municipal healthcare services. Nevertheless regionalization, that’s to say service, institution and practice integration, was not performed satisfactorily, thus jeopardizing the health system decision making process and causing disputes between municipalities over financial resources instead of developing an interdependent and cooperative net. This way, it is important to analyze if health regionalization has a good potential for being used as public governance tool. The present study aims at giving answers to the following research problem: What are the contributions of regionalism to the State of Paraná public governance applied to health? Besides that, it also aims at assessing the State of Parana health regionalization to identify healthcare gaps and help the State actions through public governance principles applied to healthcare. Therefore, the study used a quantitative-qualitative, exploratory and descriptive research, plus secondary data concerning bibliographic and documental research. The present study analyzed the current hospital bed distribution by compared to the ideal distribution allowing the identification of healthcare gaps in the regional healthcare centers, besides considering medical specialties in the State of Paraná. The study conclusion is that health regionalization is an important tool for reducing healthcare gaps concerning hospital beds permitting the use of seven to ten public governance principles applied to healthcare, as established in the present study, and shows health regionalization is an important pubic governance tool.
