Abstract

Nowadays, there is a tremendous discussion of the B5G/6G air interface and its different propagation models that are suitable for the mid and high bands (mmWave) spectrum. The key RF characteristics and planning parameters are traffic types, propagation modeling, and techniques for estimating system throughput and capacity. The goal of this research is to describe initial planning and radio deployment perspectives for the implementation of B5G/6G new radio (NR) technology in indoor scenario. This scenarios is suitable to predict and design the modern mobile networks inside administrative new capital known as Knowledge City. In addition, This paper study and compare the path loss while using three different path loss propagation models close-in (CI), floating intercept (FI) and alpha-beta-gamma (ABG) model inside a building at different frequency bands 28 GHz, 73 GHz, and 300 GHz where the signal effected by distances, obstacles and surrounded environment. The case study is in indoor conference meeting room inside a building in one of the "Knowledge City in New Administrative Capital" that can accommodate up to 80 people, where the antennas can operate with each other directly line-of-sight (LOS) or are obstructed non-line-of-sight (NLOS). Also, antennas use matched polarization vertical to vertical direction (V-V).The paper also proposed coverage and capacity network planning model for indoor radio networks using high-frequency bands in the mmWave and sub-THz ranges.
