Abstract
A cell group is formed from three cells, each of which has a site equipped with antennas. The antennas differ from one another in terms of horizontal orientation and cover all horizontal directions. The cell groups are arranged in a repeating pattern such that a cell having a site assigned different frequency is interposed between cell groups assigned the same frequency, thereby constituting a minimum unit area to be repeated.
