说明：  一种提高室内覆盖 的 解决方案 就 是所谓的 FAPs （ femtocell 接入点 ） 或家庭 基站 。 这些都是 为 室内使用 而设计的 低功耗 基站 ， 这就 使蜂窝网络运营商 可以 扩大室内覆盖的 范围，比如一些受限或 不可用 的地方 。(A way to improve indoor coverage solution is called FAPs (femtocell access point) or home base stations. These are designed for indoor use of low-power base stations, which enables cellular network operators can expand the scope of indoor coverage, such as some areas limited or unavailable. )
