   Abstract : The Internet has grown enormously since the introduction of the World Wide Web in the early 90's. The evolution and wide spread deployment of cellular networks have contributed to make the Internet accessible to more people in more places. The cellular networks of today offer data rates high enough for most Internet services. READ MORE

6. 4. Adaptive Concatenated Coding for Wireless Real-Time Communications

   Author : Elisabeth Uhlemann; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Incremental redundancy hybrid ARQ; Multiple concatenated codes; Iterative decoding; Rate compatible punctured codes; Union bounds; EXIT charts; Convergence analysis; Wireless real-time communication; Quality of service; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The objective of this thesis is to improve the performance of real-time communication overa wireless channel, by means of specifically tailored channel coding. The deadlinedependent coding (DDC) communication protocol presented here lets the timeliness and thereliability of the delivered information constitute quality of service (QoS) parametersrequested by the application.

7. 5. Three problems with internetworking in cellular networks

   Author : Lars-Åke Larzon; []
   Keywords : ;

   Abstract : Over the last decade, cell phones have gone from providing the traditional interactive voice service to also include support for Internet services. Cellular networks that originally were designed for cost-efficient voice services supply low bandwidth, high error rates and long round-trip delays, which poorly fit the generous header sizes, lack of error tolerance and reliance on retransmissions of the Internet.
