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.
