Abstract: This application note discusses the development and deployment of 3G cellular femtocell base STATIONs. The technicalchallenges for last-mile residential connectivity and adding system capacity in dense urban environments are discussed, with 3Gfemtocell base STATIONs as a cost-effective solution. Maxim's 3GPP TS25.104-compliant transceiver solution is presented along withcomplete radio reference designs such as RD2550. For more information on the RD2550, see reference design 5364, "FemtocellRadio Reference Designs Using the MAX2550–MAX2553 Transceivers."

为了能够满足基站易于选址、优质快速的建站要求和易维护、低成本、高可靠的运行要求，本文对以方舱来实现一体化结构基站做出一番探讨。从系统设计的观点阐述了移动通信高性能基站天线设计的几个关键问题，介绍了智能天线技术在基站中的应用，并且用HFSS软件仿真了一种新型的对称阵子天线，该天线驻波比小于2的带宽可以达到60%，具有良好的宽频带特性。 Abstract: In order to meet the STATION construction requirement of easy site selection and fast base STATION， and meet the operational requirement of easy maintenance， low cost and high reliability， this paper discussed the unified architecture base STATION using shelter. Several key problems of high performance mobile communication base STATION antenna were illustrated from the view of system design， the application of smart antenna in base STATION was also introduced. And a novel dipole antenna was simulated by using HFSS， the VSWR of the antenna is less than 2， and the bandwidth was reach to 60%. So it has good broadband properties.
