一片覆盖区域需要多少天线与中继设备，并生成可随询价一起发出的物料清单。
Spacing factor k: 0.6-0.75 for indoor, 0.7-0.85 for outdoor. Lower means more overlap between neighbouring antennas and a higher edge level, at the cost of more units. Area per point is taken as the square of the spacing (equivalent cell area on a square layout). This is a first-pass estimate for quote preparation.
