COMP30091: Digital Wireless Communications and Networks (2008-2009)
The explosion of mobile computing driven first by the mobile telephone and now also by PDA's and laptop computers using Bluetooth, WiFi and soon WiMAX is changing the way we interact with one another and with machines. But how does wireless networking work? How is it distinct/similar to wired networks?
The course uses guided self-study so you need to be motivated to learn for yourself. A main book supplemented and enhanced with electronic resources are used.
The core 2nd year networking course has introduced the background that all computer scientists need. That course is almost entirely about wired networks. This course extends the networking to wireless networks which are introduced. The course also covers digital telephone networks. The main goal is for students to understand how today's wireless local area networks (WLANs) operate and to be aware of current developments in this domain.
To develop awareness and experience of:
The way in which wireless communications has developed since the early 1900's.
To learn the basics about how radio waves are propagated from a transmitter to a receiver.
To learn basic information about modulation of different signals onto radio waves.
To learn about the techniques used to modulate digital data onto radio waves.
To overview the different types of digital communications in use today.
To understand how wireless local area networks (WLAN) operate today.
To gain insight into current developments in WLANs.
Have a knowledge and understanding of the architecture and communication protocols for wireless networks used in both fixed and mobile applications.
Have an understanding of the latest developments in wireless network protocols and technologies.
Be able to aid in the design and implementation of systems using wireless communications technology.
Assessment of Learning outcomesAll the learning outcomes are assessed by examination.
Contribution to Programme Learning OutcomesA3, A5, B1 and B3 Method of Assessment: The course assessment will be divided between a fortnightly on-line test (40%) and the final exam (50%). There will be around 5 or 6 in-course tests where most questions will be multiple choice. The tests will each last 10 minutes and will consist of a maximum of 10 questions each. The tests will be sat during the fortnightly lecture. The final overall test mark will be the mean of each student's best 4 test scores. Peer Group Knowledge Sharing: A course newsgroup will be used for students to ask questions, exchange information etc. It is hoped that other students will respond to issues raised as well as the course lecturer. Time permitting; some issues raised in the newsgroup will also be discussed during the lectures.
The course will consist of a small number of formal lectures to introduce important ideas, ensure that core material is covered and provide direction for private/shared study. The rest of the course is divided into a set of modules. Progress should be roughly 1 module per fortnight. For this course, students are expected to spend a minimum of 5 hours per fortnight learning on their own or in small groups.
Every module has a set of core topics that everyone must study. The core parts of each module will be examined using short on-line tests. The point of these tests is to ensure that you are indeed doing the work and also to provide you with formative feedback about your progress during the course not just when the examination results are published. In addition to the core material, each student will be expected to pick some topics to study in slightly more detail.
The main source of information for each module is the course textbook. This book is a valuable resource now and for the future, everyone will need a copy of this book. It will be necessary to supplement your knowledge from readily available resources and through your own research using, for example, web searches. A collection of some useful sources for each module will be made available via the course's Moodle web page. There are also self-test resources so you can test your own knowledge and progress as you learn.
