A Simulation Approach to Indoor Channel Design for 5G Networks at 39 GHz

This paper presents investigations on propagation within an indoor environment based on extensive simulations; the study was based on simulations conducted using Ray-tracing software at 39 GHz. The study considers some of the directional and omnidirectional channel characteristics, including path loss exponent (PLE), delay spread (DS), the number of ray clusters, and the number of rays per cluster in both line-of-sight (LOS) and Non-LOS (NLOS) propagation scenarios. It was found that PLE and DS are frequency-dependent. Also, the number of clusters tends to follow a Poisson distribution, while LOS tends to follow a decaying exponential distribution.
