Mobile Wireless Technology
The new 5G technologies is to develop in the world as the fastest and latest technology in the telecommunication world.
The 5G generation technology for cellular systems will probably start to come to  around in 2021.
First generation
1.    1G:First technology
phones were analogue and were the first mobile or cellular phones to be used. Although revolutionary in their time they offered very low levels of spectrum efficiency and security.
Second generation
2.    2G: Second technology
This technologies were based around digital technology and offered much better spectrum efficiency, security and new features such as text messages and low data rate communications
Third generation
3.   3G: Third technology
This technology was to provide high speed data. The original technology was enhanced to allow data up to 14 Mbps and more.
Fourth generation
4.   4G: Fourth technology
This generation all-IP based technology capable of providing data rates up to 1 Gbps.
Fifth generation
5.  5G: Fifth technology
One of the big challenges facing 5G is standardization. There are already multiple groups working to come up with standards around interoperability, backward compatibility with older technologies (4G, 3G), and making sure the network will be future-proof. While many companies agree that a global standard is needed Building the infrastructure for 5G is also a huge task, with issues around spectrum and installing new antennas. 5G is likely going to rely, at least in part, on higher-frequency bands. There is more space in those airwaves available, but at such high frequencies, signals can’t travel nearly as far as they can over the frequencies used for 4G, resulting in a poor connection
5G spectrum:


One major enabler for 5G will be the release of frequency spectrum and this needs to be managed on a global scale to ensure commonality and also the reduction of interference between services, especially those operating globally. This process is managed under the auspices of the International Telecommunications Union, ITU.
To manage the process of spectrum allocations, large international meetings called the World Radio Conference, WRC are held every four years. There is one in 2015, another in 2019, and this is followed four years later by one in 2023..
5G Creating new communication

The future of mobile communications is likely to be very different to that which we are used to today. While demand for mobile broadband will continue to increase, largely driven by ultra high definition video and better screens, we are already seeing the growing impact of the human possibilities of technology as the things around us become ever more connected.
