Wireless Communication

Abstract

In this paper we have tried presenting a all-inclusive assessment of 5G cellular networks. 5G will be the coming fifth-generation wireless broadband technology will be based on the IEEE 802.11ac standards. An noteworthy aim of 5G is to expunge the transformations among wired and wireless networking to house the increasing growth of mobility and network users. It is believed that 5G will work at a better speeds and provide better coverage when compared to current 4G networks. 5G is expected to operate with a 5Ghz signal and is established to offer speeds of up to 1 Gb/s for tens of connections or tens of Mb/s for tens of thousands of connections. Huawei, who ia one of the leading vendors of 5G claims that 5G will provide speeds hundred times faster than 4G LTE offers. 5G has advantage over other networks as it also rises network expandability up to hundreds of thousands of connections. The paper begins by providing an overview of existing surveys that deal with 4G and 5G cellular networks. Then, we give a idea of 5g vendors .understanding the working of 5g, uses of 5G, projects on 5G and comparisons of 5G with other current networks

Abstract

In today’s world approximately every person is using internet to fulfill their tasks using a wireless or a wired network. It is often exasperating, when the slow speed of network leads to limited connectivity and long processing hours. The speed of internet is a foremost concern for everyone be it home, business, entrepreneurs, organizations and institutions is propel for getting precise information at the right time and place, which requires rapid internet connectivity and huge spectrum of channels. The Wireless-Fidelity (Wi-Fi) provide the speed of 150Mbps, according to the Standards of IEEE 802.11n, which is not sufficient to satisfy the requirements demanded by users over the network. In order to eradicate the limitations of Wi-Fi, a new technology Li-Fi can be used. Li-Fi stands for Light Fidelity which was proposed by the German physicist Harald Haas in 2011 TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication. Li-Fi is a wireless communication system which uses light as a carrier signal instead of traditional radio waves used in Wi-Fi. This paper demonstrates a brief overview about Li-Fi technology. Li-Fi can obtain the speed of about 10Gbps. Li-Fi is a wireless optical networking technology which uses light emitting diodes (LEDs) for data transmission. The term Li-Fi refers to Visible Light Communication (VLC) technology in which light acts as a medium to deliver high-speed communication in a manner similar to Wi-Fi. Li-Fi is more energy and bandwidth efficient and more secure when compared to Wi-Fi. Li-Fi can be used along with Wi-Fi, hand in hand both would provide a great wireless communication has the limitations of Wi-Fi are overcome by Li-Fi and since Li-Fi can be implemented on in short distances which is overcome by Wi-Fi.
