White Paper: Radio fundamentals for cellular networks

Cellular technologies have advanced from first generation (1G) analog technologies to advanced high performance fourth generation (4G) and fifth generation (5G) systems in just four decades. Despite the increase in complexity of wireless standards and devices, cellular technologies maintain a set of common principles that form the basis behind the design of cellular systems. In…

Testing LTE-Advanced (Rel.10)

This application note summarizes the Rohde & Schwarz test solutions for LTE-Advanced (Release 10) using Vector Signal Generators, Signal and Spectrum Analyzers and the Wideband Radio Communication Tester.

LTE UE receiver performance measurements

LTE user equipment (UE) receiver performance has significant impact to cellular radio network coverage and capacity. It determines the maximum data throughput across the air interface between the LTE base station (eNB, evolved node B) and the mobile network subscriber UE, thus it determines the total capacity across the air interface. Therefore, it is one…

Higher Order MIMO Testing with the R&S®SMW200A Vector Signal Generator

Due to its outstanding performance the R&S®SMW200A vector signal generator is ideal for testing MIMO receivers in a vast variety of applications offering maximum usability at minimum form factor. It can generate up to eight antenna signals simultaneously in its digital baseband – all standard-compliant and with antenna-specific coding. In addition, it can simulate the…

LTE-A Base Station Transmitter Tests

3GPP TS36.141 defines conformance tests for EUTRA base stations (eNodeB). Release 13 (LTEAdvanced Pro) added several tests, especially for Narrowband Internet of Things (NB-IoT). This application note describes how all required transmitter (Tx) tests (TS36.141 Chapter 6) can be performed quickly and easily by using signal and spectrum analyzers from Rohde & Schwarz. A few…

LTE-A Base Station Performance Tests

3GPP TS36.141 defines conformance tests for EUTRA base stations (eNodeB). Release 12 (LTEAdvanced) added several tests, such as those for PUCCH format 2 and PUSCH with TTI bundling and enhanced HARQ pattern. This application note describes how all required performance tests (TS36.141 Chapter 8) can be performed quickly and easily by using vector signal generators…

1MA195: LTE-A Base Station Receiver Tests

3GPP TS36.141 defines conformance tests for EUTRA base stations (eNodeB). Release 12 (LTEAdvanced) added several tests, such as those for contiguous and non-contiguous multicarrier and/or carrier aggregation (CA) scenarios. This application note describes how all required receiver (Rx) tests (TS36.141 Chapter 7) can be performed quickly and easily by using vector signal generators from Rohde…
