Abstract: Mobile wireless communication has experienced few generations. the first Technologies started with an analog system and developed into a digital communication system. 1G made possible for mobile communication, it has bandwidth between 10 kHz up to 30 kHz, this generation was first launched by Japanese company Nippon Telegraph and Telephone (NTT). in the second generation offered a 9.6 kbps data rate which increase up to 300 Kbps. it has second phase with 200 kHz bandwidth. In third generation Voice and data communication were focused. All generations were making diverse new features. Fourth generation (4G) technology was used in many countries around the world with providing high mobility and high-speed data rate by internet protocol (IP). However wireless communication systems facing new challenges every day which even fourth-generation cannot solve. Therefore, experts have already started an investigation also tested on beyond fourth-generation wireless systems with no limitation. To create new generation technology, companies and researchers need to focus five fundamental new technologies. These new technologies will deliver a good data rate less than a millisecond of a slowdown and bring a high speed of downlink. To realize how 5G technology is different from the current generation 4G, we need to understand all of these five technologies.Abstract: Mobile wireless communication has experienced few generations. the first Technologies started with an analog system and developed into a digital communication system. 1G made possible for mobile communication, it has bandwidth between 10 kHz up to 30 kHz, this generation was first launched by Japanese company Nippon Telegraph and Telephone (NTT). i...Show More
