Rohde & Schwarz achieves breakthrough in sub-THz research with 140 GHz multi-channel transceiver characterizationRohde & Schwarz is advancing its pioneering sub-THz research in the D-Band and has reached important milestones. In collaboration with the Berkeley Wireless Research Center (BWRC), the test and measurement expert has successfully characterized a TX/RX multi-antenna chip (CHARM) operating at up to 140 GHz, using their D-Band over-the-air (OTA) test chamber. Academia and industry leaders agree that the 110 GHz to 170 GHz frequency range, known as D-Band, is critical for beyond 5G and 6G mobile communications and future automotive radar applications.

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 of the most important measurements to verify the actual receiver performance of individual devices, and a key metric to compare different devices, in particular.This paper shall give an introduction to receiver performance measurements and discusses the measurement metrics as well as the challenges of over the air (OTA) measurements.

Comprehensive test solutions guide for production and R&D
Small cell is a compact base station with smaller form factor and lower transmission power in comparison to the conventional macro base station. It covers relatively small area and serves less users. Usually, small cell can be integrated into the existing mobile network. By the evolution of radio access technology, the role of small cell has been changing through the evolution path. In the 2G/3G time, its role was to provide coverage in corner cases. Later during LTE, networks are not just providing coverage but capacity too. Small cells were then used to provide the addition capacity where required without adding additional spectrum. Now in 5G era, network operators use densification as an important strategy to provide seamless 5G services which demand coverage, capacity and performance too. With use cases requiring the 5G millimeter wave (mmW) rollouts, it makes sense to use small cells for densification due to the propagation characteristics of mmW.In this application note, we will shed light on the testing aspects of a small cell throughout the product life cycle with particular focus on the production test solution for the small cell device under test (DUT) in FR2 (frequency range 2, mmW frequency band) in Over the Air (OTA) environment for option 6 split based on radio communication tester R&S®CMP200 and OTA chamber R&S®CMQ200. The document is complemented with more insights into test solutions used in typical R&D test applications towards the second half of the application note.
