The current state of 5G technology for cellular systems is very early in development. Many companies are looking at technologies that could be used to become part of the system. In addition to this, several universities have created 5G research units focused on the development of 5G technologies. In addition to this, standardization bodies, in particular 3GPP, are development aware, but are not yet actively planning 5G systems. Many of the technologies that will be used for 5G will begin to appear in the systems used for 4G and then as the new 5G cellular system begins to formulate in a more concrete way, will be incorporated into the new 5G cellular system.
The main problem with 5G technology is that there is such a huge variation in requirements: fast downloads to small data requirements for IoT that any system will not be able to meet these needs. As a result, a layer approach is likely to be adopted. As one commentator put it: 5G is not just a mobile technology. It is ubiquitous access to high and low data rate services.
