2. 11. On the weightless economy: Evaluating ICT sectors in the European, Asian and African regions

   Author : Ibrahim Kholilul Rohman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; probit; Gini coefficient; Europe; economic growth; ICT sectors; panel cointegration; diffusion; Asia; Africa; panel data; broadband; input-output; production; weightless economy; cellular;

   Abstract : One of the most distinctive characteristics of the weightless economy is the increasingly important role of the Information and Communication Technology (ICT) sectors, which, according to the OECD (2009), consist of ICT products and media and content products. The ICT sectors have been identified as contributing significantly to the economy through production, measured by the value of the ICT outputs produced and the spillover effects to the other sectors, and the diffusion due to the higher penetration rate of ICT products and services and the impact of the end-users.

4. 12. Frequency Reconfigurable and Linear Power Amplifiers Based on Doherty and Varactor Load Modulation Techniques

   Author : William Hallberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gallium nitride GaN ; wideband; Class-J; linear; microwave; radio frequency RF ; Doherty; broadband; AM AM; silicon carbide SiC ; bandwidth; power amplifier PA ; AM PM; varactor; dynamic load modulation DLM ; fifth generation mobile networks 5G ; energy efficiency;

   Abstract : In future mobile communication networks, there will be a shift towards higher carrier frequencies and highly integrated multiple antenna systems. The system performance will largely depend on the available RF hardware. As such, RF power amplifiers (PAs) with improved efficiency, linearity, and bandwidth are needed. READ MORE

7. 15. A comprehensive framework for future broadband policy: Assessing the EU initiative

   Author : Orada Teppayayon; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; broadband policy; sector agenda; information society; strategic agenda; the EU;

   Abstract : For more than two decades, broadband has been recognized in the EU as having great benefits for economic and social development. This recognition is evident in the first EU policy document on the telecommunications market – the 1987 Green Paper – which assumed that harmonization and liberalization through competition mechanisms could be used as tools to bring all those benefits to European citizens.
