Riassunto analitico
In earlier generations of mobile technology, voice communications were always the focus, even when other services were made available. Gradually, new services were added, such as text messaging in 2G, video calls in 3G, and always-on data connections in 4G. The next generation, 5G, aims to make further major changes to services with multiple requirements. These networks have the ability to provide services ranging from high data rate mobile broadband to ultra-reliable low latency communications. (5G) mobile network services have finally begun as many applications, as well as new services, are expected to enter our lives and work. As the next-generation infrastructure, 5G networks aim to significantly increase the speed and capacity of 3G/4G mobile communications. In addition, 5G will provide dramatically evolved communications networks that connect massive numbers of devices to the Internet and provide high reliability and low latency. This review provides an overview of the requirements that 5G will address and also discusses the underlying technologies, particularly from the perspective of the evolution of millimetre wave technology. After 2019, 5G has been turning out in many countries. To support the need for increased traffic capacity, the millimetre wave (mmWave) frequency spectrum is being used for the first time for mobile wireless telecommunications technologies. Many questions arise for the telecommunications industry with the advent of 5G mmWave, including what the impact of mmWave antenna performance would be in a mobile terminal and how to evaluate the impact. This literature review first describes the requirements for 5G and three main technologies to support it. It then describes the characteristics of the millimetre wave (mmWave) technologies that will be newly introduced in 5G and the rationale for their development.

Abstract
In earlier generations of mobile technology, voice communications were always the focus, even when other services were made available. Gradually, new services were added, such as text messaging in 2G, video calls in 3G, and always-on data connections in 4G. The next generation, 5G, aims to make further major changes to services with multiple requirements. These networks have the ability to provide services ranging from high data rate mobile broadband to ultra-reliable low latency communications.
(5G) mobile network services have finally begun as many applications, as well as new services, are expected to enter our lives and work. As the next-generation infrastructure, 5G networks aim to significantly increase the speed and capacity of 3G/4G mobile communications. In addition, 5G will provide dramatically evolved communications networks that connect massive numbers of devices to the Internet and provide high reliability and low latency. This review provides an overview of the rerequirements that 5G will address and also discusses the underlying technologies, particularly from the perspective of the evolution of millimetre wave technology.
After 2019, 5G has been turning out in many countries. To support the need for increased traffic capacity, the millimetre wave (mmWave) frequency spectrum is being used for the first time for mobile wireless telecommunications technologies. Many questions arise for the telecommunications industry with the advent of 5G mmWave, including what the impact of mmWave antenna performance would be in a mobile terminal and how to evaluate the impact.
This literature review first describes the requirements for 5G and three main technologies to support it. I then describes the characteristics of the millimetre wave (mmWave) technologies that will be newly introduced in 5G and the rationale for their development.
