Abstract
Millimeter wave technology will be dominating the fifth-generation networks due to the clear advantage of higher frequency bands and hence wider spectrum. In this paper, the indoor radio wave propagation at 28 GHz is studied by developing an efficient three-dimensional ray tracing (ETRT) method. The simulation software based on the ETRT model has been verified by measurement data. The received signal strength indication and path loss have shown significant agreement between simulation and measurement. Compared with the conventional shooting bouncing ray tracing method, the proposed ETRT method has better agreement with measurement data.

According to one worldwide cellular data demand projection, the expected volume of wireless data will be 143 Exabyte per quarter by 2021, which is seven times higher than the demand in 2016 [1].Network operators are presently facing fulminant traffic for mobile data demand and existing 4G/LTE cellular network service providers are operating near to the theoretical limit
This paper presents the 3-D Ray tracing (RT) simulation results for radio propagation prediction under an indoor environment
Using the proposed new model, more rays are allowed in some potential zones and not in all directions, which reduces the computational complexity without reducing valid paths between TX and Rx
Summary
According to one worldwide cellular data demand projection, the expected volume of wireless data will be 143 Exabyte per quarter by 2021, which is seven times higher than the demand in 2016 [1]. Network operators are presently facing fulminant traffic for mobile data demand and existing 4G/LTE cellular network service providers are operating near to the theoretical limit. The present networks cannot acquire such high capacities [2]. Because of heterogeneity, coordination, and cognition handle in 5G network and beyond, this will be very complicated [3,4]. The utilization of millimeter wave (mmWave) frequency spectrum is to achieve wider bandwidth, it is one of the best approaches for the progress of 5G Wireless Communication Systems (WCS) [5]
