The Internet of Things (IoT) is considered the driving force of current and future wireless communications. In release 13, 3GPP has specified Narrowband-IoT (NB-IoT) as a new physical layer. This application note gives a short introduction to NB-IoT and shows the easy measurements with Rohde & Schwarz instruments.
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… Read more »
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 »
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… Read more »
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 »
Radio frequencies in bands around 28 GHz are being discussed as candidates for mobile communications of the fifth generation (5G). Beam steering will be a key feature in the context of 5G. It will be a major challenge to test the beam steering capabilities of base stations and user equipment in every phase from research… Read more »
Designing and implementing an active phased array antenna requires precise characterization of individual components and the integrated performance of the array. To ensure an accurate test of the intended adaptive nature of the active phased array antenna, the embedded algorithms need to be tested as well. This application note aims to explain test procedures and… Read more »
Millimeter-wave bands are of increasing interest for the satellite industry and under discussion as potential 5G bands. Antennas for 5G applications make use of the shorter element sizes at these high frequencies to incorporate a larger count of radiating elements. These antenna arrays are essential for beamforming operations that play an important part in next… Read more »
