Wireless communication has achieved ever-greater popularity in the last two decades, and has already become an important part of our everyday lives. This subject is aimed towards giving an overview of the most important principles and state-of-the-art technologies that are making wireless communications possible.
Course description for study year 2023-2024. Please note that changes may occur.
The subject provides an overview of the history, the main principles and system architectures of wireless and mobile communications and the development towards the todays' systems. Different techniques and technologies for physical layer (e.g., wireless channel and modulation) and the data link layer (e.g., media access control and error control) are described. Network and transport layers are briefly treated with a particular focus on the further challenges and constrains given by the wireless communications. Different wireless short- and medium-range network architectures, such as IEEE 802.11 (Wi-Fi) and IEEE 802.15 (Bluetooth and ZigBee), are presented. The evolution of the mobile architectures (i.e., GSM, UMTS, LTE, and 5G) is introduced. Low-power long-range network architectures (i.e., LoRa/LoRaWAN, NB-IoT, and LTE-M) are also presented. The security threats and available security tools and techniques in wireless networks will be also discussed. In addition, certain wireless and mobile applications and services can be also discussed, such as Internet of Things (IoT), Multi-access Edge Computing, Industry 4.0 and Smart City.
Fundamentals of wireless communications
Wireless networking challenges and protocols
Design principles for mobile and wireless networks
International standards for wireless networks
Identify the performance, reliability and security challenges in a wireless communication environment
Evaluate and select the appropriate wireless network technology for a given application and environment
Design of simple wireless networking protocols
Understanding the fundamental technologies of the wireless networks
Understanding the theoretical and practical abilities and issues of the various wireless communication technologies
Required prerequisite knowledge
Project report and written exam
Form of assessment
No printed or written materials are allowed. Approved basic calculator allowed
Project report counts 30% and written exam counts 70% of the final grade. Both parts must be passed to get a final grade.The project is carried out in groups.If a student fails the written exam, it is possible to resit next semester. Project report must be taken again next time the subject is lectured.
Completion of mandatory individual assignments are to be made at the times that are assigned. Absence due to illness or for other reasons must be communicated as soon as possible to the laboratory personnel. One cannot expect that provisions for completion of the lab assignments at other times are made unless prior arrangements with the laboratory personnel have been agreed upon.
There must be an early dialogue between the course coordinator, the student representative and the students. The purpose is feedback from the students for changes and adjustments in the course for the current semester.In addition, a digital course evaluation must be carried out at least every three years. Its purpose is to gather the students experiences with the course.
