5G NR Reduced Capabilities (RedCap) network scanning
Purpose of RedCap: RedCap is designed for use cases requiring reasonable data throughput, cost-efficient devices, reduced power consumption and smaller device footprint to support applications like wireless industrial sensors, video surveillance and smart wearables in which ultralow latency isn’t essential. Technology basics: Understanding the technology basics helps facing configuration complexities and avoiding potential coexistence issues with regular 5G. RedCap field verification: New mobile network technology introductions like 5G RedCap benefit from field measurements during their typical life-cycle phases (engineering, network roll-out, and operation). Measurement Techniques: In early phases of new technologies, passive network measurements using network scanners are reliable and effective in detecting actual network and cell configurations.

Today’s complex circuits must integrate several components that feed on different power levels. A robust circuit that ensures interoperability of these components needs carefully designed, clean and stable power distribution networks for power timing. At lower voltage levels, tolerance is defined in percentages and can make precise measurements challenging.

Spectrum clearance in mobile networks is becoming ever more important as operators use new bands that previously contained other services. This is particularly important for the 5G NR rollout. 5G NR has already initiated a worldwide deployment of TDD networks in an unknown radio environment where unwanted transmitters can create uplink interference masked by downlink signals, making interference hunting particularly demanding. Automated detection of interference signals before a network switches on can be a big help in addition to traditional manual techniques.

Best practices for national regulatory authorities
Key points:Importance of field measurements: Traditional network planning tools and models only offer an estimated view of mobile coverage. Field measurements are conducted under real geographical and load conditions, and therefore provide a more accurate picture and can discover interferences more effectively. Coverage investigations: When deploying a mobile network, operators must adhere to regulatory standards and licensing conditions. As a result, regulatory authorities carry out field measurements on a regular or ad hoc basis to validate compliance or investigate customer complaints. This process identifies coverage gaps and areas of poor network quality, enabling regulatory authorities to take actions to enhance service quality for consumers and guide network expansion.Foster competition: If the field measurements of the coverage and performance are performed on a scale representative of a given country, the transparency of these results can promote healthy competition between operators and better service for consumers, which is essential for economic growth and social development.Measurement Techniques: The harmonized methodology for measuring and evaluating data throughput and QoE based on popular services is described in ETSI TR 103 559.

Transformers are passive devices that are primarily used to convert or "transform" alternating current (AC) from one voltage level to another. One very common application of transformers is in AC to DC power supplies, in which mains voltage is stepped down before being rectified and filtered to produce DC. There are numerous other applications for transformers, such as providing electrical isolation or for impedance matching.This educational note provides a brief technical introduction to measurements made on the types of transformers used in electronics. These transformers are typically physically small, work on relatively low voltages or powers, and are used for “indoor” applications. Although many of the testing concepts described below also apply to the larger, higher-power "outdoor" transformers used for electrical power distribution, the specific tests and test procedures for these types of transformers are often specified by standards bodies such as the IEEE and may differ substantially from the types of measurements described here.Read this educational note and dive into the discussion about the six most important transformer measurements: turns ratio, mutual inductance, phase angle, primary and secondary inductance, leakage inductance, and interwinding capacitance.
