ORIGINAL RESEARCH 5G: a new era of wireless communication Ketanpreet Kaur 1 • Shailesh Kumar 1 • Anupam Baliyan 2 Received: 8 January 2018 / Accepted: 7 May 2018 Ó Bharati Vidyapeeth’s Institute of Computer Applications and Management 2018 Abstract The increasing rate of connectivity is driving towards a new era of virtual reality which is possible with the high end speed internet. The connectivity between every object is forming a shape of latest technology, i.e. IoT (Internet of Things) which requires the enormous networking connection. Comparing to all those previous technologies, the outrageous demands which are placed on 5G are continuing getting very high, with data rates of up to 20 Gbps and the capacity a thousand times greater. 5G networks will be providing a flexible platform for the upcoming services such as IoT, Artificial Intelligence, Cloud computing, Natural Language Processing, machine communication and all the latest technologies. In this research paper important components of 5G will be dis- cussed. All the important aspects like latency, MIMO, cell distribution, speed, mmWave, slicing, Spectrum will be briefly described which will form a new Platform for all the upcoming technologies.

Life is changing fast and so is the speed of connectivity. With the latest technology comes high expectations, hence the need of high speed connectivity with everything around us became a necessity. Latest 5G is the fifth generation in the category of radio systems and advanced network archi- tecture which will deliver extreme broadband, ultra-ro- bustness with low latency connectivity and massive networking for humans and the Internet of Things (IoT). Exclusively by 5G, this programmable world will be transform our individual lives, economy and society. Before the evolution of 4G and LTE, it was impossible to think about the connectivity in Giga bytes per seconds that too wired but with the new technologies coming into frames it is now possible to connect the things with the speed of Gbps. 5G will be far more than being a new radio technology, it is a development of whole new technology which will be a prime and optimal topic for the researchers. It will combine the existing Radio Access Technologies (RATs), and it will add original RATs optimized for explicit bands and deployments, setups and use cases. 5G will furthermore implement a radically different network architecture based on Network Function Virtualization (NFV) and Software Defined Networking (SDN) tech- nologies [3]. 5G networks drives to have be programmable, software driven besides managed holistically to enable a diverse and profitable range of services. Networks will be offering speeds more than 10 Gbps and extremely low latency. 5G is the upcoming platform that will allow advancement in various industries, ranging from the IT industry to the Transportation industry, & Shailesh Kumar salesh.kumar@gnauniversity.edu.in Ketanpreet Kaur ketanpreet.kaur@gmail.com Anupam Baliyan Anupam_hod1976@gmail.com 1 Faculty of Computational Science, GNA University, Phagwara, Punjab, India 2 Bharati Vidyapeeth’s Institute of Computer Applications and Management (BVICAM), New Delhi, India 123 Int. j. inf. tecnol. https://doi.org/10.1007/s41870-018-0197-x
