5G Test

Proper testing of 5G and RF systems is essential for the successful development, deployment, and operation of next-generation wireless networks in 5G Test. As 5G continues to expand, testing must address far more than just coverage areas and peak data rates—it must verify complex performance parameters across multiple domains.

5G networks introduce significant challenges due to their reliance on higher-frequency bands, including sub-6 GHz and millimetre-wave (mm Wave) spectrum, as well as the implementation of advanced technologies like massive MIMO, beamforming, and carrier aggregation. These innovations demand highly accurate RF testing to evaluate network speed, bandwidth, latency, and signal integrity under real-world conditions.

To meet these demands, advanced RF test equipment such as Vector Signal Analyzers (VSAs), Vector Signal Generators (VSGs), and Signal and Spectrum Analyzers play a critical role. These instruments are capable of generating, capturing, and analyzing wideband signals—often over 1 GHz of instantaneous bandwidth—with frequencies that extend beyond 50 GHz to support mmWave testing. Such equipment is essential for evaluating transmitter and receiver performance, modulated signal quality (e.g., EVM, ACLR), and over-the-air (OTA) characteristics. and ensuring accurate results in 5G Device Testing.

As 5G technologies evolve, test strategies must also adapt. The emergence of cloud-native architectures, virtualized network functions, and edge computing introduces new complexities in test setup, orchestration, and scalability. Automated test systems are becoming increasingly important to manage massive MIMO configurations, where dozens or even hundreds of antenna elements require precise synchronization and calibration.

Additionally, robotic antenna positioning systems are being developed to enable accurate and repeatable OTA measurements, especially in anechoic chambers or compact antenna test ranges (CATR). These systems support the high spatial precision required for beam characterization, directional gain measurements, and compliance with regulatory standards.

In conclusion, as 5G continues to redefine wireless communications, RF and system-level testing must advance in parallel—pushing the boundaries of what current instrumentation and methodologies can support. Only through comprehensive and precise testing can the full potential of 5G networks be realized.
