There are many product options to provide indoor coverage, such as active or passive distributed antenna systems (DAS), this chapter discusses the Pico base stations utilizing the normal 3GPP architecture and Femto base stations that use the special architecture. Although it addresses the 3G Home Node B (HNB), most of the information is relevant to both 3G and LTE. In 3GPP, a large amount of the home base station work for the two radio technologies is done jointly although some differences apply, related to e.g. architectural aspects. The chapter outlines some of the key differences. Femto is a complete new way of building the mobile network. It covers a number of new aspects including interference control, architecture, mobility, security and access control, which are all different from the macro cell networks. The chapter gives more detailed description about the femtorelated solutions and their backgrounds. antenna arrays; femtocells; macrocell networks
