Production Measurements on 3GPP WCDMA Femtocells

Femtocells or Home base stations are an important development for cellular networks. This new emerging base station class demands economical test equipment suitable for mass production. Rohde & Schwarz range of signal generators and analyzers contain models suitable for testing all classes of base station. With the R&S SMBV100A Vector Signal Generator and the R&S FSV Signal Analyzer Rohde & Schwarz supply two instruments which are particularly suited for the fast and cost-efficient calibration and test required for Femtocells. This application note describes the tests commonly used during the production of Femtocells, focusing on WCDMA, HSPA, and HSPA+ technology. Tests, test plans and hardware setups for Femtocells with and without receiver diversity are detailed. Find hints about the instrument settings and have a look at typical measurement results. An introduction to simulating GPS/A-GPS signals for testing the GPS receiver of a Femtocell completes the paper.
