Existing multimedia systems used in education mostly address only two senses by using two communication channels (visual and audio) of the five human senses (sight, hearing, taste, smell, and touch), limiting the potential efficiency of learning. This paper presents a survey on existing technical opportunities for the development of an immersive learning environment. Four components of the immersive environment - visual, audio, olfactory, and haptic are described and discussed in the paper. In particular 3D displays, head mounted devices, 3D sound systems, olfactory displays, haptic devices, and interaction devices are presented.

Multimedia has become an ordinary component of modern software and hardware. Sound, graphics, and animation are present at almost every application of both desktop and mobile platforms. However, human senses cover more than two media. Thus, the transition from Multimedia to Mulsemedia (MULtiple SEnsorial MEDIA) is quite natural. Mulsemedia enriches traditional multimedia content with new media objects, such as olfactory, haptic, and thermoceptic ones. Mulsemedia gives new opportunities for immersive technologies and opens new horizons for communication, education, advertising, and medicine. However, new media demand new technological solutions implemented as both hardware and software. The paper gives an overview on existing standards, hardware, and software that can support transition from Multimedia to Mulsemedia as well as on future trends that can have positive impact on the development of mulsemedia-based technologies.

5G-Xcast is a project focused on Broadcast and Multicast Communication Enablers For the Fifth Generation of Wireless Systems. Within the project for the most defined use cases, it is necessary to provide needed throughput, delay and reliability. For this purpose, the multi-connectivity approach can be used. 5G multi-connectivity is one of the key enablers in order to satisfy the demanding requirements of 5G mobile networks. Multilink is one kind of multi-connectivity within the 5G-Xcast project. This paper describes multilink benefits, its high-level description and implementation to the 5G core architecture for better user experience and reducing costs of mobile network operators.
