Communication systems play a crucial role in
various industries and human life. Since the emergence of
legacy communication systems, human lives have become
more interconnected. At first, wired communication
systems with short-distance connections were invented
then evolved into wireless systems, which we now heavily
depend on in our daily lives. Zero Generation (0G) (precellular
communication systems) was the beginning of
Wireless communication, followed by the First Generation
(1G), which introduced cellular networks using analog
transmission. The Second Generation (2G) introduced
Global System for Mobile Communication (GSM) systems
with digital transmission technology which is regarded as
more effective and robust than Analog technology. Later
generations, such as Third Generation (3G) with Universal
Mobile Telecommunications System (UMTS) and Fourth
Generation (4G) with Long Term Evolution (LTE) evolved
to meet new requirements. With each generation,
communication capabilities have significantly advanced to
break limitations of last one and meet requirements in
current one. Fifth Generation (5G) has been in deployment
since 2020 with many advanced technologies being
leveraged due to the diverse scenarios of 5G, and research
on Sixth Generation (6G) is currently in progress. In this
work, we provide a thorough analysis of mobile
communication systems to help researchers understand
each generation specifically. Since 6G is still in the
research phase and has not yet been deployed, we highlight
key challenges and issues to assist researchers in
identifying solutions and exploring potential 6G
advancements.
