The present article aims at examining the promising capabilities of new generation mobile networks for the implementation of first-class online education based on advanced immersive technologies. The study describes the main functional drivers of the modern end-to-end 5G architecture and proposes several options for its application in today’s socio-economic life. In order to investigate public opinion toward 21st-century education and identify the prioritized requests for university training among potential students, a survey of the target audience in the business administration segment was conducted. It involved 100 MBA students of the Graduate School of Business of Kazan Federal University (Russia) and 200 business workers. After reviewing the survey outcomes, it was concluded that the main competitive advantages of an educational course are its pace, convenience, and effectiveness in goal achievement. The current work presents the analysis of promising educational opportunities of 5G for creators of study materials and students, such as the extensive use of AR, VR, and robotics; creation and implementation of new educational services that support multimodal interaction and are rich in multimedia content. Educational opportunities of 5G also include unhindered remote interaction between learners; extensive use of AI applications during training; provision of high-quality and real-time mobile education; and implementation of personalized training systems.
