Summary:
In this paper, the effect of the antenna spacing on the inter-cell interference has been analyzed using a raytrace simulation. Based on the raytracing simulation, the narrower antenna spacing can mitigate the inter-cell interference since the lower order eigenvalue can be degraded. The analysis of the achievable rate under the interference condition has showed that the moderately narrow antenna spacing, i.e., one wavelength, yields the best average rate in this environment. Also, it is found that this antenna spacing improves the rate by 40 % compared with that of d = 5λ0 when two cells are placed at the rooms next to each other.
