By 2020, the next major cellular wireless standard has been adopted.* This continues the trend seen since 1981 in which a new mobile generation has appeared roughly every 10th year. The 5G family of standards is a major leap from previous generations in terms of power and functionality. Among its key features are:
- Pervasive networks providing ubiquitous computing. The user can simultaneously be connected to several wireless access technologies and seamlessly move between them. These can be 2.5G, 3G, 4G or 5G networks, Wi-Fi, WPAN or any other contemporary access technology. Multiple, concurrent data transfer paths can be easily handled.
- Group cooperative relay. High bit rates are now available in a larger portion of the cell, especially to users in an exposed location in between several base stations. This is achieved by cellular repeaters, together with macro-diversity techniques (also known as group cooperative relay), as well as beam-division multiple access.
- IPv6, where a visiting care-of mobile IP address is assigned according to location and connected network.
- High-altitude stratospheric platform station (HAPS) systems, delivering high-speed Internet service to very large geographical areas.
- Wearable devices with AI capabilities, offering greater levels of user interaction and personalisation.
- One unified global standard with full compatibility, no matter what brand or model.
