Designing and testing 3GPP W-CDMA base transceiver stations

Posted: 07 Jul 2010     Print Version  Bookmark and Share

Keywords:W-CDMA  base transceiver stations  physical layer W-CDMA 

W-CDMA is a wideband digital cellular technology used for the 3G cellular market. The 3GPP system employs W-CDMA in FDD and TDD modes. To limit its scope, this application note focuses on the FDD mode of W-CDMA, although most of the content is applicable to both modes. Whenever the term W-CDMA is used throughout the application note, it refers to the 3GPP (Release 99) specifications for W-CDMA FDD mode.

This application note focuses on the physical layer (layer 1) aspects of W-CDMA base transceiver stations (BTS). It consists of the following:
• A brief overview of W-CDMA technology;
• A discussion of design issues and measurement concepts related to the technology that are important for the W-CDMA BTS air interface because of the differences between W-CDMA and its second generation (2G) predecessors (specifically GSM);
• A discussion on the specific requirements of the femtocell;
• A table with an overview of the BTS transmitter, receiver and performance conformance tests required by the 3GPP specifications;
• A list of Agilent Technologies' solutions for the physical layer of W-CDMA BTS design and test.
