2. 21. Multi-Gigabit Radio System Demonstrators for Next Generation Mobile Networks

   Author : Jingjing Chen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fronthaul; E-band; modem; millimeter-wave transmission; mobile backhaul; multi-gigabit; differential coding; phase noise mitigation; FPGA; 16-QAM; DQPSK; point-to-point radio; centralized baseband;

   Abstract : Driven by the exponential growth in mobile broadband subscriptions and mobile data traffic, transport capacity of mobile networks has to be enhanced accordingly, including wireless backhaul and the emerging fronthaul networks. Utilizing wide bandwidth is the most straightforward way to capacity upgrade. READ MORE

4. 22. Internet Access and QoS in Ad Hoc Networks

   Author : Ali Hamidian; Lunds universitet; []
   Keywords : ad hoc networks; QoS; IEEE 802.11e; MANET; ad hoc routing; distributed resource reservation; Wireless computer communication; IEEE 802.11; ad hoc; mobile ad hoc networks; EDCA; AODV; distributed QoS;

   Abstract : It is likely that the increased popularity of wireless local area networks (WLANs) together with the continuous technological advances in wireless communication, also increase the interest for ad hoc networks. An ad hoc network is a wireless, autonomous, infrastructure-less network composed of stations that communicate with each other directly in a peer-to-peer fashion. READ MORE

5. 23. Mobile Network Operators and Cooperation : A Tele-Economic Study of Infrastructure sharing and Mobile Payment Services

   Author : Jan Markendahl; Jens Zander; Per Andersson; Heikki Hämmäinen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication theory; Telekommunikationsteori;

   Abstract : Mobile network operators are currently faced with a number of challenges at the market. The revenues from voice services have decreased the last couple of years. Mobile broadband access services are being adopted and the demand is increasing. The increasing traffic volumes require investments in order to increase the network capacity. READ MORE

6. 24. Moving Networks, a Better Way to Serve Vehicular Users

   Author : Sui Yutao; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; small cells; device-to-device communication; vehicular small cells; Moving relay node; moving cells; moving networks; interference management; ultra-dense networks; vehicular penetration loss;

   Abstract : Nowadays, a great number of mobile broadband users are vehicular. It is very common that people are using their mobile devices either for working or entertainment when they are on the go. We are expecting mobile broadband to offer comparable experience everywhere, e.g. READ MORE

7. 25. Exploiting Energy Awareness in Mobile Communication

   Author : Ekhiotz Jon Vergara Alonso; Simin Nadjm-Tehrani; Daniele Puccinelli; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless transmission energy; energy consumption; mobile devices; power measurements; application energy; data pattern; trace-based simulation;

   Abstract : Although evolving mobile technologies bring millions of users closer to the vision of information anywhere-anytime, device battery depletions hamper the quality of experience to a great extent. The massive explosion of mobile applications with the ensuing data exchange over the cellular infrastructure is not only a blessing to the mobile user, but also has a price in terms of rapid discharge of the device battery.
