WIRELESS NETWORK AND SECURITY2
Introduction
The aim of this report is to highlight the contrasting features of 5G
technology in terms of band width, network coverage and the speed of the
uploads and downloads. In due course of this procedure, the contrast has been
laid with respect to other networks like 4G, 3G and 2G. A comparative analysis
has been performed on these networks based on these parameters and the
outcome highlights the outstanding features of 5G network which has eventually
helped it to gain supremacy and pioneer ground in the domain of communication
network. This report incorporates the following aspects- comparison between the
networks, description of the 5G architecture, analysis of the associated risks and
the obstacles encountered in the way of 5G network coverage.
Comparison of cellular networks (5G, 4G, 3G and 2G)
Communication Spectrum
The communication spectrum of 5G network is harmonised. The target set
up by most of the regulators is to make the availability of 3.5 GHz spectrum for
the mid-bands of 5G network. Even some of the regulators aspire to increase the
spectrum of the 5G network up to 26-28 GHz. In the generalised scenario, 5G
spectrum operates within 3 distinct ranges for facilitating the purpose of
supporting widely dispersed coverage [1]. The ranges incorporate- 1-6 GHz,
above 6 GHz and Sub-1 GHz. The spectrum of Sub-1 GHz is designed to satisfy
the purpose of delivering wide spread coverage for the rural, urban and
suburban arenas and rendering support to the Internet of Things (IoT).
4G network also coined LTE network, operated within an operational
frequency of range 600 MHz to 2.5 GHz. This range incorporates the frequencies
of 700 MHz, 600 MHz, 2.3 GHz, 1.7/2.1 GHz and 2.5 GHz [2]. The bandwidth
allocated per channel in the case of 4G network varies within the range of 5 MHz
to 20 MHz, where in the case of 5G network the range varies from 5 MHz to 100
MHz. The relationship between the throughput and the bandwidth follows a
directly proportional relationship.
Owing to this fact, the enhancement in the bandwidth of 5G network in
contrast to the 4G network has facilitated the enhancement in the throughput for
the 5G network [1]. There is the global acceptance of the fact that the 1800
MHz band is the best suited operating bandwidth for the 4G network for the
