家庭基站（英语：Femtocell，又译为毫微微蜂巢式基地台），最初叫接入点基站（英语：Access Point Base Station），是一个小型的蜂窝基站，一般被设计为在家庭室内或小的商业机构中使用。通过宽带接入（如DSL，有线电缆，光纤）连接到运营商的网络，可以集成2G、3G、WiFi于一机。

2008年全球移动通信大会（Mobile World Congress；MWC）首次展出Femtocell技术，得到Orange、T-Mobile青睐，“Femto”本意是指10的负15次方，又称为毫微微。家庭基站最早在欧洲流行，是一种超小型手机基站设备，相比Microcell基地台(指通常覆盖范围2公里以内)以及Picocell微型基地台（指通常覆盖范围200米以内）更小型，家庭基站的覆盖范围约12米。部分情况下，Femtocell可以提供更大范围的覆盖，以满足办公环境的需要。

In telecommunications, a femtocell is a small, low-power cellular base station, typically designed for use in a home or small business. A broader term which is more widespread in the industry is small cell, with femtocell as a subset. It is also called femto AccessPoint(AP). It connects to the service provider’s network via broadband (such as DSL or cable); current designs typically support four to eight active mobile phones in a residential setting depending on version number, and eight to 16 active mobile phones in enterprise settings. A femtocell allows service providers to extend service coverage indoors or at the cell edge, especially where access would otherwise be limited or unavailable. Although much attention is focused on WCDMA, the concept is applicable to all standards, including GSM, CDMA2000, TD-SCDMA, WiMAX and LTE solutions.
