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… Read more »

Antenna Array Testing – Conducted and Over the Air: The Way to 5G

5G networks will need to offer more capacity and flexibility while lowering the operational expenses of the system. Two new technologies can simultaneously address both the increase in capacity and the increase in energy efficiency: Virtualization & Massive MIMO. This white paper provides an overview of test solutions addressing current and future requirements for antenna… Read more »

LTE and Bluetooth® in-device coexistence with WLAN

This application note employs preliminary theoretical analysis and demonstrates how the problems of in-device coexistence can be measured. Exemplary, the effects of LTE and Bluetooth® traffic on the WLAN performance of a commercially available smartphone are examined. These examples will also enable the reader to design tests for complementary scenarios.

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… Read more »

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… Read more »
