Millimetre wave antenna deployment in a single room environment

摘要

In wireless system deployment, the system planner must deploy base station antennas at the most appropriate locations to maximise system performance. In this study, the effect of transmitting antenna deployments on coverage in a single room office environment at millimetre wave frequencies is investigated using a three-dimensional implementation of Geometrical Optics. Multiple antenna deployments and artificial environmental modifications (convex reflectors) are also investigated in order to quantify how they might improve coverage compared to a single antenna deployment. A quantitative estimate of shadowing inside the office volume indicated that there are significant non-illuminated regions which cannot be eliminated by simply increasing the transmitted power. It is shown that such regions can significantly be reduced in size if an appropriate deployment of multiple antennas or passive reflectors is adopted.
