2. 11. Coexistence, Deployment and Business Models of Heterogeneous Wireless Systems Incorporating High Altitude Platforms

   Author : Zhe Yang; Blekinge Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless communication; Coexistence; High altitude platforms; Resource sharing; Capacity; Business model; Techno-economic;

   Abstract : The increased demand for broadband communications has led to the rapid development of the conventional terrestrial and satellite wireless communications systems. One of the main challenges to next generation wireless systems is to deliver high-capacity and cost-efficient solutions to cope with an increasing usage of broadband services and applications.

5. 13. Understanding the digital divide: Empirical studies of Thailand

   Author : Chalita Srinuan; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; accessibility; availability; affordability; Thailand; social inequality; market mechanism; digital divide; government intervention;

   Abstract : The term digital divide was introduced in the 1990s to define the gap separating those who have access to new forms of information and communication technologies (ICTs) from those who do not. Later, scholars started looking more closely at the use of ICTs, instead of solely paying attention to access. READ MORE

6. 14. Hybrid Routing in Next Generation IP Networks : QoS Routing Mechanisms and Network Control Strategies

   Author : Antoine B Bagula; Björn Pehrson; Bukhard Stiller; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teletraffic systems; Teletrafiksystem;

   Abstract : Communication networks have evolved from circuit-switched and hop-by-hop routed systems into hybrid data/optical networks using the Internet as a common backbone carrying narrow- and broad-band traffic offered by a multitude of access networks. This data/optical backbone is built around a multi-technology/multi-protocol routing architecture which runs the IP protocols in a collapsed IP stack where ATM and SONET/SDH have been replaced by the suite of Generalized Multiprotocol Label Switching (GMPLS) protocols.

7. 15. Innovation and Intellectual Property: Strategic IP Management and Economics of Technology

   Author : Marcus Holgersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; open innovation; innovation economics; research and development; Intellectual property right; technology management; licensing; value appropriation; strategy; theory of the firm; governance;

   Abstract : Innovations and technological developments have been recognized for their central importance for economic success and growth at least since the 1930s. Intellectual property (IP) and intellectual property rights (IPRs), such as patents, trade secret rights, and copyrights, have during more recent decades caught increasing attention, and, mainly due to various developments at macro level, IP has become an important source of competitive advantage at micro level in many industries.
