White Paper: Testing passive networks in distributed antenna systems (DAS)

In the last decade, worldwide consumer demand for cellular services has driven network operators to strive for better network coverage and within that coverage footprint, better network capacity. Since more than 80 % of cellular traffic comes from inside a building, in-building coverage, and in-building capacity have become a focus of this effort. In addition,…

CPRI RE Testing

More and more mobile radio networks implement remote radio equipment (RE) that is connected to the base station main unit via a digital interface using standardized transmission protocols such as CPRI. This application note explains in detail the instrument setup and configuration needed to successfully test your remote radio head.

Measuring Multistandard Radio Base Stations

3GPP Release 9 Technical Specification (TS) 37.141 covers multistandard radio base station conformance testing. This application note introduces the concept of multistandard radio base stations as well as solutions for transmitter and receiver tests based on R&S® signal generators and R&S® signal and spectrum analyzers.
