5. 3. Fundamental Limits in Wireless Wideband Networking

   Author : Tan Tai Do; Mikael Skoglund; Tobias Oechtering; Olav Tirkkonen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The rapid growth of the wireless communication industry recently does not only bring opportunities but also challenges on developing radio technologies and solutions that can support high data rate as well as reliable and efficient communications. Two fundamental factors that limit the transmission rate are the available transmit energy and the available bandwidth. READ MORE

6. 4. Fair Scheduling and Resource Allocation in Packet Based Radio Access Networks

   Author : Torgny Holmberg; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication engineering; HiperAccess; network calculus; fairness; Scheduling; resource allocation; Telekommunikationsteknik;

   Abstract : Wireless communication systems are by nature and by regulations limited in bandwidth and are therefore limited in capacity. Services with Quality of Service (QoS) requirements will enforce a more efficient utilisation of the available capacity. READ MORE
