• In this paper, a detailed investigation of millimeter wave Non LOS (line of sight) conditions and proposed multi-hop protocol is described. Ratio under received power threshold is calculated by measuring the complex permittivity of a used desk and propagation loss characteristics along the surface of a desk plane. This calculation result shows Non LOS conditions existence even though line of sight is secured on the desk environment. Visibility estimation in the typical Japanese office is calculated using light emission method and shows high rate of Non LOS condition. In order to minimized Non LOS conditions, multi hop protocol is proposed. Terminal BER profile is used for finding to the most suitable extension point (EP). The use of twin link communications and an automatic handover mechanism, which are minimized to Non LOS condition, are proposed.
