NETWORKING 2
Introduction
The next generation (5G) is more effective and reliable in terms of data communication
that replaced 4G cellular networks and systems. The main evolution compared with
previous generations is that 5G technology improved data rate speed which helps the
consumers for transferring data in an effective way [1]. New IoT and wireless networks
require advanced cellular network for reducing errors and problems and 5G is the latest
communication technology that addressed risks occurred in the IoT devices. The major
objective of this investigation is to identify the importance of 5G networks in
communication systems and compare the features of cellular networks along with the
risks and issues. It is argued that the readers require a platform for understanding the
key issues related to the wireless networks and analyze the key features of 5G
technology. The outline of this report will include several sections for example;
comparison of cellular networks, 5G architecture and security attacks or issues occurred
in 5G networks.
Comparison of cellular networks
2G cellular network
2G technology was developed and implemented in the year 1999 that used digital
cellular networks in order to perform data transmission over the networks. From recent
literature, it is identified that the communication spectrum of 2G networks involves 1.8
GHz frequency in order to provide digital communication to the consumers [2]. The
bandwidth of 2G over the previous generation is very high (900 MHz) and also included
digital modulation technology in order to modulate the transmitted signals or data. With
the help of the 2G cellular network, the users were able to perform data communication
and also provided 64 kbps data rate which is not enough for completing long-distance
communication. As compared with previous-generation 2G enables text message services
to the consumers and transferred signals are effective and reliable that helped the users
for obtaining better signals. Therefore, it is stated that 2G networks are not much secure
that produced data breach and security threats that affected the personal data of
consumers.
