The challenge at millimeter-wave frequencies is that the propagation characteristics approximates to that of light. In a nonline-of-sight scenario, when even the mobile station (MS) is near the base station, the attenuation may be tens of dBs due to shadowing and obstructions. Increasing the number of base stations reduces such effects but at the expense of cost and complexity. An attractive method to mitigate such shadowing effects is to use dedicated active or passive relay stations. Proposed here is a network infrastructure in the form of a 3D pyramid. It consists of a single access point with four (but not restricted to) active relays operating in parallel in a medium sized room of 400 m/sup 2/. Simulation is performed in a sophisticated 3D ray tracing tool. Human shadowing densities of 1 person/400 m/sup 2/ up to 1 person/1 m/sup 2/ are set to test the robustness of such a system. Results show that comparing to a normal system with just a single access point either mounted on the ceiling or at the same level as a MS; the pyramid relaying system provides superior coverage and capacity
