Basic Info

This course allows students to understand basic principles of Wireless communication. Its knowledge is a necessary in order to understand and design actual and future wireless systems and network. They form and enabling component for whole ICT infrastructure. (Cloud, IoT, IIoT, cellular networks, etc.) The main effort in this area is to increase throughput in wireless communications systems and networks and at the same time to fulfill requirements on QoS expressed via BER, delay, reliability, security, fairness and others. This subject is a basis for study and understanding following subjects such as: Architecture of wireless 4G and 5G networks. However the acquired knowledge could be exploited in broad application area of communications systems and networks. Some preliminary basic knowledge about digital communications principles is for studying advantageous.
