In this article, Fifth generation mobile technology is termed 5G. It is basically a standard notation, used for a major phase of mobile telecommunication other than 4G standards. After the overall success of fourth generation (4G) mobile communications which was based on the platform named “Long Term Evolution (LTE)-Advanced standard” developed by the Third Generation Partnership Project (3GPP), the industry along with the research department such as International Telecommunication Union — Radio communications Standardization Sector (ITU-R), 3GPP, has been continuously working on the 5G mobile communication standards through some projects, such as the EU FP7 METIS and independently. In the year 2015, a paper has published in which it was reported that ITU-R developed a vision for 5G mobile communications. This vision supports the accommodation of explosive growth of data traffic through enhanced mobile broadband (eMBB). It also supports massive machine-type communications (MTC), along with ultra-reliable and low-latency communications (URLLC). This paper presents a review of the innovation, updates, and advancements from the first generation (1G) to the fifth generation (5G). Also, the network capabilities providing reasonable broadband wireless connectivity for all generations of telecommunication are discussed here.
