5th Generation of Mobile

The 5G mobile cellular communications system provides a far higher level of performance than the previous generations of mobile communications systems. The new 5G technology is not just the next version of mobile communications, evolving from 1G to 2G, 3G, 4G and now 5G. Instead, 5G technology is very different.

Previous systems had evolved driven more by what could be done with the latest technology. The new 5G technology has been driven by specific uses and applications. 5G has been driven by the need to provide ubiquitous connectivity for applications as diverse as automotive communications, remote control with haptic style feedback, huge video downloads, as well as the very low data rate applications like remote sensors and what is being termed the IoT, Internet of Things. 

The current status of 5G technology for cellular systems is very much in the early development stages. Very many companies are looking into the technologies that could be used to become part of the system. In addition to this, a number of universities have set up 5G research units focussed on developing the technologies for 5G In addition to this the standards bodies, particularly 3GPP are aware of the development but are not actively planning the 5G systems yet. 

Many of the technologies to be used for 5G will start to appear in the systems used for 4G and then as the new 5G cellular system starts to formulate in a more concrete manner, they will be incorporated into the new 5G cellular system. The major issue with 5G technology is that there is such an enormously wide variation in the requirements: superfast downloads to small data requirements for IoT than any one system will not be able to meet these needs. Accordingly, a layered approach is likely to be adopted. As one commentator stated: 5G is not just mobile technology. 

It is ubiquitous access to high & low data rate services.
