摘要

因應下一世代行動通訊對於超高傳輸速率的需求，採用超微型基地台(FAP)的Femtocell網路架構被視為可行且有效的未來行動通訊網路方案。低功率、體積小而價格低廉的FAP適合佈建於室內空間，可改善現行行動網路室內覆蓋率不佳的情況，為使用者提供高頻寬且低收費的行動語音與數據通訊服務。然而，Femtocell網路與現行行動網路並存時，將產生網路架構可行性、是否需要變更或新增通訊協定、以及網路元件控管等新議題。本文就需求面與功能面探討Femtocell網路架構方案、產業趨勢以及標準訂定現況，並探討未來技術發展方向。

Femtocell emerges to meet the demand of high transmission rate of the next generation communications. Femtocell Access Points (FAPs) are low-cost cellular base stations. Femtocell which possesses the feature of low transmission power is a feasible solution to provide sufficient bandwidth for mobile communication service in the indoor environment. However, the coexistence of Femtocell and Macrocell will bring about the issues of integrating Femtocell with existing network infrastructure, and the alteration of communication protocols. The management of network resources and elements is also a consideration. In this paper we survey the market trend and the state of the art in standards, and investigate the Femtocell network architecture from functional and requirement aspects. Furthermore, we discuss the future development of Femtocell.
