Fifth generation (5G) mobile networks demand large bandwidth with the explosive growth of data driven applications. This necessitates enormous amount of spectrum in the Millimeter wave (mmWave) bands to greatly enhance the communication capacity. The mmWave band offers the potential for high-bandwidth communication channels in cellular networks. Relative to conventional networks, dense mmWave networks can achieve both higher data rates and comparable coverage. The paper presents the performance analysis of mobile networks in terms of propagation path loss, coverage probability and data rates for different mm wave operating frequencies of 28GHz and 73GHz. A scenario of multi-users in a micro cell is considered in different environments i.e. rural, sub urban and urban regions and the performance parameters in each case are analyzed. Millimeter wave cellular networks at 28GHz offer less rain attenuation compared to 73GHz and is useful for next generation communications with enhanced data rates and coverage.
