Millimeter wave for 5G mobile communication application

The enormous increase of mobile data growth needs a super-efficient mobile network that provides a superior communication while at the same time judiciously dealing with the shortage ofglobal bandwidth. When the mobile service providers compete among themselves to provide high quality of service (QoS), and low latency video and multimedia applications for wireless applications, the major constrain that impedes the progress is limited available spectrum range between 700MHz to 2.6GHz where each of the service providersare allocated approximately 200MHz across all the different cellular bands of the available spectrum. This can be surmounted by using Millimeter wave (mm-wave).The main focus of the paper is two-fold: to throw some lights on how mm-wave can be used for 5G cellular and to discuss how the next generation mobile users can be highly benefited by prudently using the bandwidth available in the mm-wave spectrumranging from 3 to 300GHz.In addition to the fact that the usage of mm-waves can substantially reduce the size of various components, especially the antenna size, using steerable antennas at both base and mobile stations make mm-wave a paramount and viable option for its usage in cellular mobile applications.
