5G Technology

Over the last 20 years we can observe a dynamic evolution of mobile networks. First milestone was the introduction of 2G GSM networks, that for the first time enabled wireless access to voice services further enriched by international roaming. It was followed by 3G UMTS networks that introduced significant improvement in the packet services, but also offered the legacy circuit-switched ones. Over time the data transmission prevailed over speech communication and became the most important service for both subscribers and operator. As a consequence 4-th generation of mobile networks, known as LTE were introduced. This new technology was completely dedicated to packet services, and offered enormous improvement in user throughput. Currently we can observe dynamic development of LTE networks in every part of the globe. Nevertheless new end-user services like Mobile Broadband, Internet of Things, Tactile Internet and many others have requirements that need another step forward towards the new 5-th generation of mobile networks. 5G is expected to be commercially available by 2020. However the standardization and research is already in mature stage. Based on this information we can quite precisely estimate, how 5G networks will look like, what services will be provided, what technologies will be used. 5G Technology course is an intermediate technical course, which provides the latest available information about all aspects of architecture, functionality, requirements, services of the future 5-th generation mobile networks.
