Now-a- days researchers are focusing on so called 5 th Generation mobile networks. To increase the communication capacity the future Fifth generation mobile wireless network is expected use a large bandwidth of frequency spectrum in the millimeter wave bands. Device to device (D2D) Millimeter wave communication technology will be one of the most attractive technologies which are going to be implemented in future 5G wireless cellular networks to provide a very high speed data rate more than recent 4G networks. In this review article we have described briefly the propagation and some of the technical challenges in D2D. Basically in the traditional wireless cellular networks devices were communicating with each other through base stations. Here in the fundamental network architecture part we have surveyed the hybrid combination of 4G and mm wave communication. Apart from this we also discussed some of the potential application of mm wave communication technology in 5G. Keywords— 5G; D2D; mm wave; high speed data; propagation; technical challenges; 4G. I. INTRODUCTION Now a day‟s the use of mobile telephones and other wireless smart devices are increasing day by day. The demands of today‟s consumers have shown significant change in bandwidth hungry applications like video streaming and multimedia file sharing have already exceeded the limits of current wireless systems. The increasing requirement for higher data rates and capacity has forced researchers towards critical thinking for the next generation (5G) cellular systems. The Next generation 5G cellular network is being developed to avoid the high data traffic between two mobile devices [1] and also it is being developed to increase the data rates between two smart devices. Table presented below summarizes the evolution of 1G to LTE/ 4G in brief. This new transmission method assures notable interpretation gains in context to link reliability, spectral efficiency, system capacity, and transmission range [14]. As per current observation it has been predicted that, in every 10 years a new generation is available with the users to fulfil their demand on data speediness and also it has been assumed that the future fifth generation mobile wireless cellular network will do an exceptional transform in the capacity of wireless cellular networks and also Multi giga bits per second data rate would also be provided to access various applications [1]. Also it has been predicted that 5G would provide data speed up to 4000 to 5000 times more than that of current cellular network usage. The usage of D2D technology has not been taken in to consideration in first 4 generation of mobile wireless cellular networks. Because of several trends in the wireless market, the operators‟ attitude towards D2D functionality has been changing day by day. Recent scenarios indicate a growth in the number of context-aware applications. These applications require location finding and telecommunication with adjacent
