Control form Exam


The main goal of the course is to provide students with knowledge and skills for modern wireless communication technologies. The principles of operation of specific 3G, 4G and 5G technologies, the methods for prioritizing users for these technologies and the resources for resource allocation are thoroughly considered. Students are introduced to current standards in the field of wireless communications. The methods of access control and the resources for allocating the resource for specific 4G and 5G technologies are presented. Variants of operation of heterogeneous wireless networks are considered.
