Cellular Communications

This course provides a comprehensive introduction to the science and engineering behind cellular networks. It covers selected topics such as information transmission using radio waves, encoding speech and video for transmission, error detection and correction, securing information, and cellular antenna placement. Designed as a breadth course, it offers an intuitive overview with minimal prior knowledge required. Assessments include multiple-choice exams and mandatory assignments in pairs. Access resources, slides, and updates through the provided web page.

Presentation Transcript

  1. Cellular Communications Introduction and Administration

  2. Contact details • Sasha Apartsin apartsin@gmail.com • Web Page • http://www.cs.tau.ac.il/~apartzin/CelCom2012/ • On the web page • Slides • References • Assignments submission guidelines • Prep. Material for the exam

  3. What this course is about? • Science and engineering behind cellular networks • “Breadth” not a “Depth” course • Selected subjects • How information is transmitted using radio waves? • How speech and video are encoded for transmission? • How transmission errors are detected and corrected? • How information is secured/encrypted? • How many phones can use a single cell antenna? • Where to place cellular antennas? • GSM/CDMA/LTE/WiMAX/IMS/LBS/ZZZ/YYY

  4. Plan • Each slide set is a short course on a specific subject • Start with general concepts=> applications for cellular/wireless communication • No prior knowledge is required (but it helps) • Mostly intuition and overview of each subject • Some basic mathematics will be introduced • All the material you’ll need is on slides • Additional references per subject may be published on the web page

  5. Grading • X: 65% multiple choice “close-material” final exam • Y: 20% multiple choice “close-material” midterm • W:15% mandatory assignments • G=0.65*X+0.2*max(X,Y)+0.15*W

  6. Assignments • Work in pairs (no triples, but single is OK) • Each pair submit N multiple-choice questions with solutions for each subject studied • All submitted questions and solutions with explanations are published • Exams will be combined from the submitted questions with (probably) small modifications • Provided submitted questions are of good quality

  7. Questions • Shouldn’t be too tricky. Those who listened in the class should be able to answer • Shouldn’t be too trivial. Those who wasn’t in the class should not be able to answer • N questions should cover different aspects of the studied subject • Numerical multiple choice questions are ok

  8. Finally • Detailed submission guidelines will be published shortly • Submissions via e-mail • Submission deadline will be published after each subject is covered in class • There will be about 10 assignments • Disclaimer: if submitted questions are no good or are all the same, the exam will contain “surprise questions”!

  9. Tips • Listen in class and think about what questions could be asked • Spend an hour per subject for writing down these questions • Ideally, A+B above should get you 100 on this course

  10. Cellular Network • Wireless communication system using RF waves • RF waves properties and propagation • Digital signal processing techniques • Modulation and detection • Error correction codes • Speech coding/compression • Cellular network • Multiple access • Cellular concept • Network planning • Adaptation of data protocols to cellular • Business Support Systems(Billing) • Standards
