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.

The R&S®CMQ shielding cube is a compact shielding solution for RF parametric testing. The turnkey chambers for direct far field over-the-air (OTA) measurements are ideal for testing antennas, modules and devices throughout the entire lifecycle under comparable measurement conditions: from product design to the production line.

Since antenna characteristics and quality have a major influence on the overall measurement certainty in OTA test systems, selecting the right antenna is critical. The following is an overview of the most common OTA antennas and their key parameters. Contact us for more details.

For cellular device manufacturers, 5G NR means a new complexity with a high impact on the development process. Advanced RF interfaces with antenna arrays operating in the mmWave range are making test setups and procedures more challenging. With Mobile World Congress returning to Barcelona in June 2021, Rohde & Schwarz is showcasing the latest highlights of its cellular device testing portfolio, which cover all stages from early 5G NR device design phases to conformance testing to device manufacturing.

Feedthroughs are used to run cables from the outside into a shielded environment such as an RF shielded box or an OTA chamber. This is done to maintain the shielding effectiveness of a given environment and prevent leakage of RF radiation into or out of the chamber.
