1 Välkomna till Avancerad Telekommunikation Welcome to Advanced Telecommunication Ulf Körner
2 Advanced Telecommunication The course is devided into two parts: 1. Theoretical studies; (about 4.5 cr out of 7.5 cr). This section consists of chapters 1-5, 7 and 11 in the course book. The lectures cover this part and the written exam. 2. A project; (about 3 cr out of 7.5 cr). This part deals with carry out the project and a written report. There will be a number of exersises and also Java Tutorials that will guide you through the project.

36 Advanced Communications Course book: Mobile Communications, Second Edition, Jochen Schiller, Addisson Wesley, ISBN OH can be found on: To that comes some articles that you pic up via the network.
37 Advanced Communications Review exercises The course book contains a large number of review exercises. On the course home page, I will list those exercises that are important for the understanding of the material. I urge you to go through these exercises. Several of these exercises will come up on the exam! Ex: 4.6; 18: What are the functions of authentication and encryption in GSM? How is system security maintained?
38 Advanced Communications Project: The goal of this project is to make the student familiar with one development platform for mobile applications, and to deploy a functioning wireless application which interconnects two mobile devices via a server or hub using IP over GPRS. There are several exersises coupled to the project. (See the course program!)
