WIRELESS NETWORK AND SECURITY
1. Introduction
Wireless networks could be referred to as the types of network that is
being set up with the help of radio signal frequency for the core purpose of
communicating amongst several computer devices and any other network
device. It is even being referred to as the WLAN or WiFi network and provides
some of the most significant advantages to its users [8]. This type of network
majorly utilizes wireless data connections within the network nodes and allows
business installations in an easy method. One of the most advanced wireless
network is 5G connection. The following report will be outlining a detailed
analysis on wireless network and security with relevant details such architecture
and attacks.
2. Motivation
5G or fifth generation cellular technology is the latest and the most
advanced form of wireless technology that meets with different requirements of
the ITU IMT 2020 [14]. The preceding generations of this specific wireless
network are 1G, 2G, 3G and 4G. 5G network is the digital cellular network, where
the respective service area is being covered by the providers and is being
divided into smaller geographical areas known as cells. The associated
technologies of this generation are GSM, UMTS, LTE, LTE Advanced Pro and many
more. The analog signals eventually represent sounds and the images are being
digitalized within phone that is further converted by the analog to digital
converter as well as transmitted as the bit stream. Each and every wireless
device of 5G within one cell substantially communicate by the radio waves with
the help of a local antenna array or lower power automatic transceiver from the
common frequency pool, getting reused in geographically separated cells [9].
Therefore, 5G is the most effective and significant wireless network generation
amongst the rest of the wireless networks.
3. Comparison of Cellular Networks
A detailed comparison of the existing cellular network generations such as
2G, 3G, 4G and 5G in five distinctive comparison factors is given below:
