Summary:
This paper presents an investigation of radio-wave propagation characteristics in the 5 GHz band in a residential two-story house. We investigated the 3-D angular spectra of incident waves when a transmitter and a receiver were set on the first floor and on the second floor, respectively. It was found that the strongest wave arrived at the receiving antenna from the direction of the transmitting antenna, penetrating through the ceiling of the first floor. Furthermore, we estimated the channel capacities of a 4-by-4 MIMO by using a 3-D angular spectrum. From this, a 1.6- fold increase in capacity was achieved compared with that achieved in the horizontal plane by choosing a suitable elevation angle, including the direction of the transmitting antenna.
