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.
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.
This application note explains how to perform LTE base station measurements over the air (OTA) using the R&S®FSH4/8/13/20 handheld spectrum analyzer. It describes the required measurement setup and explains the results obtained with the different measurement modes.
This application note and associated application software may be used to conduct psychoacoustic speech quality evaluation for Voice over LTE (VoLTE) connections. The measurements are based on recommendations ITU-T P.862 and ITU-T P.863, respectively. The CMWrun example sequences perform decoder / encoder calibration, connection setup for the UE under test and subsequent speech quality analysis… Read more »
Location Based Services (LBS) involves the process of determining where a device is located. Global Navigation Satellite System (GNSS) based solutions are highly accurate and the technology of choice for absolute position accuracy, providing the device has a good line-of-sight, but this is not always the case. A device can be in a highly dense… Read more »
