Health care will undoubtedly change over the next 20 or 30 years as eHealth technologies become increasingly used and accepted (Treister, 1997; Yellowlees, 1997, 2001). At a global level, the health care system is moving away from episodic care to concentrating on continuity of care, especially for patients with chronic diseases (Yack, 2000), who will give rise to the greatest disease burden in the future (Murray & Lopez, 1999). Many countries are gradually moving away from a focus on the service provider to a focus on the informed patient, and from an individual approach to treatment to a team approach. Increasingly there is a concern less with the treatment of illness and more with the need for wellness promotion and illness prevention, which, of course, parallels a shift away from traditional care to community care.

We present a new phase realization approach applied to design the broadband single-layer reflectarray antennas. Such an optimization technique minimizes the adverse effects of frequency dispersion which limit the bandwidth of reflectarray antenna designed by traditional methods. Using this new approach leads to obtaining a wideband reflectarray by finding the optimum element arrangement on the antenna aperture. The excellence of such an approach in comparison with its counterparts is to decrease the dependency of wideband reflectarray design to the element phase behavior. For really assessment this phase synthesis approach, a single-layer reflectarray compromising of square patches loaded with split rings is designed with the help of this optimization technique. It is analytically and numerically shown that the simulated reflectarray can be a broadband antenna in which Side Lobe Level (SLL) value is reduced. To validate the obtained numerical results, a designed 29×29cm 2 reflectarray is fabricated and measured. Measurements demonstrate 1.5dB gain bandwidth of about 28% covering 12-16GHz frequency band. Its |SLL| is also less than-17dB (<-13.5dB for uniform excitation arrays). Such a design technique is applicable for approximately all reflectarray elements and relieves the designer from complex elements and multilayer structures.

This paper explores the contexts and motivations that underpin the uptake of Australia’s National Broadband Network (NBN). The findings are drawn from a mixed-methods research study of households using surveys and interviews conducted in 2011 and 2012 in an early release site of the NBN rollout. Whilst use and non-use have traditionally been treated as questions of digital access, inequality and exclusion, there is evidence for emerging forms of non-use characterized by more critical and discriminating approaches. We contribute to this evidence, but our findings suggest that use and non-use of high speed broadband do not occur in isolation or as an expression of individual choice, but as part of increasingly dense household media ecologies of digital infrastructures, devices, services and knowledge.

A popularização das conexões à Internet em banda larga foi um importante avanço tecnológico no desenvolvimento da rede e, no que tange à circulação de informações e o acesso ao conhecimento e cultura, tornou-se a expressão mais importante do que se convenciona chamar de convergência tecnológica ou de mídia. O processo de expansão do acesso à banda larga é, entretanto, notadamente e historicamente desigual, criando os chamados abismos digitais. A universalização da banda larga, entendido como o acesso equitativo e qualitativo à rede, tem ganhado a atenção de governos e tornou-se alvo de uma série de políticas em diferentes países. No Brasil, o Programa Nacional de Banda Larga (PNBL) foi o mais importante conjunto de políticas neste sentido. O objetivo desta pesquisa é justamente entender o papel do PNBL (2010-2014) no contexto de universalização do acesso à Internet banda larga, sob a perspectiva do acesso privado domiciliar, considerando a importância que a rede tem adquirido em todo o mundo e as desigualdades observadas em sua expansão. O estudo, realizado a partir de uma revisão da literatura e de acesso a dados oficiais e a pesquisas sobre o setor, se divide em três capítulos que abordam: o contexto de formação e regulamentação do mercado de telecomunicações no Brasil, a discussão do papel das políticas públicas para a Comunicação e a análise do Programa Nacional de Banda Larga. Constatamos que o programa não cumpriu o seu objetivo inicial de conectar à Internet banda larga fixa 50% dos domicílios urbanos e 15% dos domicílios rurais. Entre as razões apontadas estão a baixa capilaridade dos planos de Banda Larga Popular e o contingenciamento dos investimentos previstos na Telebras. Uma série de questões relevantes para as políticas públicas de Comunicação se sobressaem na finalização do PNBL, principalmente a necessidade de um debate regulatório sobre a rede enquanto um serviço essencial e um planejamento estruturado para o setor a fim de dirimir os abismos digitais.

The strict relation between broadband development and economic growth and its central importance in modern economies is nowadays a demonstrated fact. Cheap and ubiquitous high-speed internet access promises to accelerate economic growth, to create new jobs and industries, to advance education and lifelong learning, to improve health care decision making, and to raise living standards; conversely, foregone broadband access imposes high economic and social costs.
In the global competition context, the U.S. and Europe have used different methods to reach the level of broadband efficiency and diffusion already existing in the Asian countries. In fact, while on one hand the US followed a deregulatory approach directed to improve infrastructure-based competition, this even with the support of private investments, on the other hand, the European Sate aid regulation tried to channel public resources with the aim to ensure service-based competition and – consequently – to improve consumers’ welfare.
In this picture, the article will analyse the European State aid policy in the broadband field – specified in the Guidelines published in 2014 – and the U.S. recent policy trends for the diffusion and implementation of broadband. As result of the compared analysis, a slow convergence of the two policies will appear, even confirmed by the Federal Communication Commission approach, now recognizing the importance of effective broadband affordability and showing, at the same time, the intention to improve service-based competition through supporting programs and a new central role for local municipalities. Given the above, according to the author’s view, the European experience in State aid policy would now provide useful e analytical tools to the American policymakers, actually engaged with the attempt to lower prices and to improve service-based competition in the American broadband market.

The rollout of the new $43bn National Broadband Network is the largest ever infrastructure
project in Australia. This thesis conducts a thorough risk assessment and cost-effectiveness
analysis on the numerous hazards facing the NBN project. The risk assessment identifies 59
hazards under 7 main failure modes of: Construction, Operation, Demand, Network,
Technology, Financing and Regulation. The most significant contributors to the overall risk
ranking are the Regulatory hazards due to the political sensitivity and lack of regulation
surrounding the NBN Co and telecommunication implementation policies. This is closely
followed by Financial hazards due to the high cost of the $43bn project and the lack of
interest from private investors due to the extended return on investment period. The
underlying key hazards include, scope creep, increased demand for high speed broadband,
increased demand for mobility/wireless connectivity, overseas bottlenecks in network design,
high prices charged by Wholesaler/ISPs, lack of private investment, lack of
telecommunication and market competition policies, and political instability.
Several remedial actions are suggested to address the key hazards and reduce the overall risk.
These include: Liberal Party’s broadband plan, NBN 3.0, NBN 3.1, NBN 3.2, domestic
caching and regulatory reform policies. The most cost-effective remedial option is a
combination of the NBN 3.0 and domestic caching, which resulted in a 61.8% reduction in
risk. This option provides a purely 4G wireless network with domestic caching relocating key
static media to domestic servers to avoid overseas bottleneck data rates. While this option is
the most cost-effective due to its low price, it still doesn’t address some key concerns for
Australia’s broadband future. The NBN 3.2 plan, which is a combination of the Liberal’s
broadband plan and NBN 3.0 wireless network, focuses on sufficient fibre infrastructure
upgrades and the demand for mobile connectivity options. When combined with domestic
caching and regulatory reform, it results in a risk reduction of 62.4%, the lowest overall risk
ranking for the NBN Risk Model. While not the most cost-effective solution due to its slightly
higher construction costs, this plan is recommended for the inherent benefits that both
wireless and fixed HFC connection options provide to the public.

Over the years, Over-the-top (OTT) has evolved from delivery of video on demand (VOD) content to users upon
request, to a broader media content provider/service, while traditional broadcasting mechanisms such as terrestrial,
cable and satellite were used mainly to deliver linear radio and video contents to many users at the same time.
Adding live channels and advanced “place and time shifting” capabilities of live TV to an OTT solution is a
significant step towards a comprehensive OTT radio or television service. The new Hybrid radio and television
experience allows the user to have a single source for all types of media content to be accessed on most of
the devices.

Kansas was the first state to close P-12 schools and move to a continuous learning model in response to the COVID-19 pandemic. A multidisciplinary group of K-State College of Education faculty researchers conducted a survey in May, 2020 to capture the voices and experiences of Kansas teachers, school counselors, and administrators during that time related to technology and broadband access, engagement and educator resiliency and self-care. Survey links were posted on the Remote Learning P-12 platform (https://remote-learning-p-12.mn.co/feed) and on the Kansas Educators Facebook group. These open links provided a sample of convenience, with 829 educators from across the state responding to the survey. The findings have implications for school districts, administrators, school counselors, teachers, and students in the coming school year.
As schools begin to make decisions about what the current and critical needs are, three tenets must be addressed for optimal school re-entry: (1) Educator and student well-being, (2) Delivery models and high-quality instruction that are conducive and responsive to varied learning environments, and (3) School operations: Precautionary measures and logistics around COVID infection and contagion. This white paper provides data, insight, and recommendations in the areas of educator and student well being and delivery models.

Broadband connectivity is a necessary service required not only in urban areas but more so in rural areas where most of the basic services are inadequate or do not exist at all. Broadband services can enable many services to be offered through information and communication technologies (ICTs) to the extent that rural people can get a chance to enjoy quality communication and other services as in urban areas and be part of the socioeconomic development of a given community. Currently, there is a number of technologies and initiatives to connect rural and urban-underserved areas at a reasonable cost but most of the rural users are yet to be connected. This paper gives an overview and a discussion on technologies, broadband connectivity models, infrastructure and policy readiness, and initiatives towards achieving connectivity and bridging the digital divide. The context of this paper is rural areas in Tanzania.

To begin to address the vestiges of racism that permeates many of our institutions and our long term structures, we have to continually ameliorate the current effects of past discrimination and racism. It starts with acknowledgment and an understanding that racism is still with us. It means acknowledging racism is also “social and institutional power plus race prejudice,” and not something we can only attribute to an individual. It also starts with the acceptance of the diversity that makes us who we are as a country. In order for us to address racism and diversity in an effective way, we must build inter-racial and ethnic relationships and develop “safe containers” in which we can have honest dialogue and deal with personal and group challenges, address issues and questions related to racism and begin to position ourselves to become effective anti-racists.

Indonesia adalah negara kepulauan yang terdiri dari banyaknya gugusan pulau dari sabang hingga marauke. Untuk dapat berkomunikasi maka dibutuhkan suatu jaringan telekomunikasi yang dapat mencakup semua wilayah Indonesia, tanpa terkecuali. Penggunaan satelit sebagai sarana telekomunikasi sangat cocok diterapkan di Indonesia. Karna dengan menggunakan satelit maka operator dapat menyediakan layanan internet hingga ke daerah rural yang tidak mendapat akses layanan intrenet oleh jaringan terestrial. Hal inilah yang menyebabkan bisnis di bidang ini sangat menjanjikan. Akan tetapi, bisnis ini bukanlah bisnis yang murah dikarenakan membutuhkan biaya yang sangat besar dalam perencanan hingga beroperasinya. Oleh sebab itu, dibutuhkan suatu penelitian yang menunjukkan layak atau tidaknya para pelaku bisnis untuk berinvestasi di bisnis tersebut. Dari hasil penelitian yang telah dilakukan, menunjukkan bahwa nilai NPV selama masa aktif satelit adalah USD 555.804.583 dengan nilai IRR adalah 7% dengan PBP 5 tahun 8 bulan. Berdasarkan parameter tersebut dapat dilihat bahwa investasi tersebut masih tergolong layak untuk dilanjutkan.

Perkembangan teknologi mobile broadband saat ini mengalami kemajuan yang pesat sesuai dengan
kebutuhan manusia akan informasi. Teknologi High Speed Downlink Packet Access (HSDPA) yang merupakan
perkembangan dari teknologi WCDMA merupakan alternatif untuk layanan internet kecepatan tinggi sampai
dengan 7,2 Mbps. Dengan berkembangnya jumlah pelanggan maka kualitas jaringan harus selalu ditingkatkan
baik jaringan luar ruangan atau dalam ruangan. Untuk mengetahui kualitas suatu jaringan seluler dapat
menggunakan metode drive test dengan melihat parameter-parameter nilai sinyal Received Signal Code Power
(RSCP), Energy Chips per Noise (Ec/No). Untuk mengetahui kualitas layanan data maka dapat dilihat dari nilai
troughput kecepatan maksimum dari hasil upload dan download. Hasil penelitian dan pengukuran menunjukan
nilai sinyal yang diperoleh untuk operator Telkomsel dan Axis nilai terbaik untuk RSCP ≥ -92 dBm yaitu dapat
mencapai target yaitu sebanyak lebih hari 80% , dan untuk Ec/No ≥ -9 dBm belum mencapai target 80%,
sedangkan untuk nilai troughput maksimal operator telkomsel dan Axis dapat mencapai target 1,9 dan 1,7
Mbps untuk download dan untuk upload operator telkomsel dan Axis sebesar 407 dan 403 kbps.

Millimeter-wave radars offer a practical solution to distinguish objects made of different materials, shapes, and compositions. In this work, radar classification of various materials is demonstrated using a broadband millimeter-wave CMOS integrated receiver. The receiver is used to record the transmitted power through multiple solid materials at various distances from the receiver in the W-band (75-110 GHz). Three supervised machine learning tools are trained by the recorded data to classify these materials into different categories. The trained classifiers were used to predict material and thickness of objects with varying distances from the receiver with accuracy levels of higher than 96% in material classification and 88% in thickness classification.
