The journey of wireless communication has
shown a great transformation over generations and this
advancement in mobile communication is still going on.
This review paper provides a comprehensive overview of
the evolutionary generations of mobile communication,
spanning from the first generation (1G) to the current
fifth generation (5G) and glimpsing into the future with
the upcoming sixth generation (6G) and seventh
generation (7G). The journey of mobile communication
began with the first generation (1G) analog cellular
networks in the 1980s, which introduced the concept of
voice calls. The second generation (2G) has delivered a
high volume and a large amount of integration. The
third generation (3G) network introduced in the early
2000s includes high-speed data transfer, enabling mobile
internet access, video calling and multimedia messaging
services. The fourth generation (4G) entered the era of
high-speed data transmission. The fifth generation (5G),
the current generation began rolling out in the late 2010s
and continues to expand globally. The sixth generation
(6G), a hypothetical next generation, aims to push the
boundaries of mobile communication even further. The
seventh generation (7G) could potentially enable highly
efficient and secure communication systems.
