Abstract(in English) | Given the increase of wireless devices in WLAN and similar systems and the shortage of available frequency channels, the need to address inter-cell-interference (ICI) is growing more urgent. ICI causes overlapping cells that adjacent cells using same frequency channel communicate, and ICI causes deterioration of spectrum efficiency per cell. As the problems of overlapping cells, we have researched, spatial domain resource sharing, this simple method of suppressing ICI using transmit beam forming in environment which two cells overlap. In this paper, we evaluate system capacity of its performance using frequency channel expected to establish with IEEE802.11ac in environment with two or more cells overlap like an apartment environment. This performance shows that the proposed method can increase the system capacity compared to conventional method. In addition, we confirmed that adjustment area of each frequency channel changes depending on bandwidth of frequency channel and cell overcrowdedness rate. |
