| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The demand of wireless LAN (WLAN) system in door environment is increasing with the widespread use of WLAN devices such as smart phone. In apartment or office environments, sum rate degrades by inter-cell interference (ICI) from a neighboring cell using the same frequency channel. In this paper, we assume that multiple access points equip an analogue beamforming control with vertical antennas. We propose cooperative interference management which mitigates ICI each other by beam tilt control. Also we clarify the effectiveness of the proposed technique by a ray-tracing simulation. Furthermore, we indicate that the proposed technique is able to improve sum rate by controlling not only beam tilt but also power. | |
