Abstract

The Spectrum generation technology provides the basic platform to perform research-oriented work. As the number of internet user increase, the bandwidth required to provide access to everyone increases. This problem is solved by introducing newer generations of network communication technologies. In the presented article, we reviewed the spectrum technologies that were required to implement the first to the fifth generation of network technology and what to expect from the coming successor i.e., the sixth generation. We discussed the real-world applications of each generation and in addition to that, we also discussed the various challenges and difficulties faced by them. We also presented an exhaustive comparison between each generation and its technologies. We discussed the Radio Over Fiber technology and how it is implemented. We have analyzed the RF spectrum and Optical Spectrum using a Radio Over Fiber System. It is said that the potential of the current generation, the fifth generation, is yet to be discovered completely. This generation brought along huge changes in AI/ML technologies. The sixth generation is said to even amplify the performance and provide greater speed, better bandwidth, and overall greater experience.
