SUPER FAST 5G

Collaboration between NEC Electronics Samsung and several academic centers in China and Iran, is investigating how software-defined cellular networking might be used to give smart phone users the next generation of super-superfast broadband, 5G. International Journal of Communication Networks and Distributed Systems provide these details.

CURRENT TECHNOLOGY:

 The fourth generation of mobile phone connection technology, 4G is as far as it has been adopted provides broadband-type connectivity for enabled devices such as smart phones, tablet computers, laptops and other gadgets.

STANDARDS ADOPTED:

•  The Mobile WiMAX standard
•   Long Term Evolution (LTE) standard

Peak speeds were set in the standards at 100 megabits per second (Mbit/s) for mobile users and ten times that for static, domestic 5G users, 1 gigabit per second. 100 Mbits/s is three times faster than the earlier 3G system but users commonly do not see data transfer at such high rates, downloads are usually at best 10 Mbits/s.

DOWNLOADABLE SPEED:

As yet there is no single standard for 5G although various systems are being touted based on rebuilding the cellular networks to be super-efficient and exploiting different frequencies with their capacity for greater data rates. The hope is to be able to achieve download speeds of perhaps 10 Gbits/s.

FEATURES:

Ming Lei of Samsung Research and Development Institute China, Lei Jiang of  NEC Laboratories, both in Beijing are working with colleagues at the University of Electronic Science and Technology of China. They have assessed the latest developments aimed at 5G systems and have proposed their own novel end-to-end (E2E) software-defined cellular network (SDCN) architecture. They  offers

             Flexibility
 Scalability
 Agility
 Efficiency
 Profitable

OTHER PROMISING TECHNOLOGIES:

They are currently building a demonstration system that will allow them to utilise  their architecture for 5G including

·        Cloud computing

·        Network virtualisation

·        Network functions virtualisation

·        Dynamic service chaining

MERITS:

)     Overcome bandwidth shortage problems

)    Improve quality of service so avoiding delays and data loss

)     Reducing the vast number of error-prone network nodes needed
