FemtoCell是移动网向IP化演进中发展出来的微型基站，主要用来解决家庭室内覆盖的问题，它具有通过用户宽带网接入、微型化、即插即用等创新特性。是3G直至4G时代，运营商一个新布署热点。

FemtoCell 就是一个即插即用的小盒子，它以客户现有的宽带互联网为中继，为现有的移动电话提供服务.它是低功率设备，集成了NB和部分RNC的功能，具有自动配置和自动优化功能以最大化地减少干扰。3G FemtoCell 解决方案为无线基站在客户家里或办公室找到了新家。作为营运商现有网络的扩展，FemtoCell能使室内和网络边缘地区更完全的覆盖。FemtoCell变室内覆盖为室内接入。

FemtoCell与pico cell的差别

　　FemtoCell借用原来pico和femto的字面意思，但架构、接入网元和接口、以及接入媒体与原来意义上的“pico cell”均不同。它借鉴UMA技术架构而成，将对3G网络和将来的LTE网络（无线接入架构)带来巨大的的变化，也必将对用户
行为方式带来革命。

各种FemtoCell技术的商用时间

　　１、公开宣布进行过FemtoCell外场实验的有：Vodafone, T-Mobile, Sprint, Telefonico O2,SoftBank Mobile, Telia Sonera等。

　　２、第一个商用FemtoCell网布设于美国。2007年第三季度Sprint在Denver和Indianapolis 布设三星CDMA femto cell，三星命名为Airave。据Infonetics公司的统计数据，截至2007年底Sprint的AIRAVE基站的销售量为2212只。

　　３、2008年9月SoftBank宣布选择Ubiquisys & NEC作为世界上第一个商用3G WCDMA FemtoCell的提供商，并于2009年1月布设。

　　４、2010 年3 月AT&T 宣布在美国全国部署并提供Femto 服务。

中国FemtoCell厂家

　　国内目前已经开发出成熟产品的有华为和博威。博威之前收购了UT的TD-SCDMA研发机构，其FemtoCell即为该机构研发出来的，博威据此成为中国领先的TD-SCDMA FemtoCell设备供应商。

In telecommunications, a femtocell—originally known as an Access Point Base Station—is a small cellular base station, typically designed for use in residential or small business environments. It connects to the service provider’s network via broadband (such as DSL or cable); current designs typically support 2 to 5 mobile phones in a residential setting. A femtocell allows service providers to extend service coverage indoors, especially where access would otherwise be limited or unavailable. The femtocell incorporates the functionality of a typical base station but extends it to allow a simpler, self contained deployment; for example, a UMTS femtocell containing a Node B, RNC and GSN with Ethernet for backhaul. Although much attention is focussed on UMTS, the concept is applicable to all standards, including GSM, CDMA2000, TD-SCDMA and WiMAX solutions.

For a mobile operator, the attractions of a femtocell are improvements to both coverage and capacity, especially indoors. There may also be opportunity for new services and reduced cost. The cellular operator also benefits from the improved capacity and coverage but also can reduce both capital expenditure and operating expense.

Femtocells are an alternative way to deliver the benefits of Fixed Mobile Convergence. The distinction is that most FMC architectures require a new (dual-mode) handset which works with existing home/enterprise Wi-Fi access points, while a femtocell-based deployment will work with existing handsets but requires installation of a new access point.
