1G, 2G(GSM), 3G(WCDMA), 4G(LTE), 5G is also Ready...

5G Is Coming...

5G (5th generation mobile networks or 5th generation wireless systems) 

The Telco world is turning to 5G. Its committed to launch in 2020.

What technology does the ‘5G’ tag stand for? Why do we need it? 

4G is still in its infancy, growing rapidly with more operators across the world deploying LTE. Why would we then start the development of a new system? Isn’t LTE enough? The answer is that the continuing growth in demand for better mobile broadband experiences is encouraging the industry to look ahead at how networks can be readied to meet future extreme capacity and performance demands. 

5G will be the set of technical components needed to handle these requirements. Unlike 4G, which is based largely on a standardized radio access technology (LTE), 5G emphasizes the development of existing techniques to improve capacity, combined with evolution in radio technology, even a change in system design principles. 

What are the different with 4G & 5G?

If 5G appears, and reflects these prognoses, the major difference from a user point of view between 4G and 5G techniques must be something else than

• Increased maximum throughput.
• Lower battery consumption.
• Lower outage probability (better coverage).
• High bit rates in larger portions of the coverage area.
• Higher number of supported devices
• Lower infrastructure deployment costs
• Higher versatility and scalability or higher reliability of communications.

 These are the objectives in several of the research papers.

What is the spectrum suggested to use for 5G?

 A better use of More radio spectrum for mobile networks is vital to meet the increased capacity and coverage demand and needs to be allocated and put into use quickly. We need to extend the amount of spectrum available by adopting new frequency bands and to use the available spectrum more efficiently, Assigned new frequency bands and wider spectral bandwidth per frequency channel for 5G is (1G up to 30 kHz. 2G up to 200 kHz, 3G up to 20 MHz, and 4G up to 100 MHz)

What is the expecting Speed of 5G?

100 Times faster than 4G  (1.056 Gbps)

How will it be deployed?

Nokia Siemens Networks sees it as a valuable additional tool for making better use of spectrum. Another pillar of 5G will be to use many more base stations, deployed in a heterogeneous network (HetNet), combining macro sites with smaller base stations and using a range of radio technologies. These will include LTE/LTE-A, HSPA, Wi-Fi and any future 5G technologies, integrated flexibly in any combination. Nokia Siemens Networks has shown that a thousand fold increase in network capacity with a 10 Mbit/s minimum downlink user data rate can be achieved by a HetNet configuration that reuses all the existing macro sites and deploys ten times as many outdoor micro sites. It would also employ up to a thousand times more indoor small cells as macro sites.

Getting the best possible performance will also be a major goal, either through evolving existing radio access technologies or building new 5G wireless access technologies to serve local areas.

Nokia Siemens Networks Research is working to identify these new complementary technologies, to enable even more efficient, scalable and versatile networks. It collaborates on research projects such as the European Union’s 5G flagship project “METIS”, as well as with universities and leading mobile operators. There’s a great deal of research and hard thinking going on at Nokia Siemens Networks into 5G and how it will be brought to commercial networks. Insight will be following developments closely through a series of regular articles on 5G in the coming months and years. 

Who are ready to deploy 5G?

Nokia Siemens Networks is already undertaking extensive research to map out the scope of 5G and has a clear vision of the three key pillars that will make this future network a reality. 

On 12 May 2013, Samsung Electronics stated that they have developed the world's first "5G" system. The core technology has a maximum speed of tens of Gbps (gigabits per second). In testing, the transfer speeds for the “5G” network sent data at 1.056 Gbps to a distance of up to 2 kilometers
