DSP Research Inc was unable to meet customer demand for 5G compliance testing, until it leveraged advanced automation

With rapidly evolving 5G specifications and an explosion in the number of connected devices, a certification and test laboratory in Japan was facing challenges in scaling its certification services to meet increased demand.

Also, Japan’s Ministry of Internal Affairs and Communications dictates that mobile devices must meet certification requirements for not transmitting radio frequency power outside of allocated bands due to signal interference limits.

Eventually, through the adoption of automation, DSP Research was able meet customer demands and save time and resources for testing and validating 5G-capable devices.

According to the firm’s CEO, Nakanishi Nobuhiro, the adoption of an automated 5G wireless test platform, together with the leveraging of its vendor’s “global footprint and comprehensive range of test capabilities” has enabled the firm “to quickly and efficiently certify new 5G devices in compliance with evolving standards and regulations” and “increase coverage of smartphone certifications where vendors have been pre-validated.”

In addition, DSP’s vendor, Keysight Technologies, Inc. is providing integrated over-the-air (OTA) testing solutions for radio frequency, signaling and radio resource management that allow test engineers to check electromagnetic compatibility, as well as demodulation testing of devices in nearly any form factor. The equipment can also be used for measuring antenna patterns; spurious emissions; and also validate the performance of a device over a wide temperature range.

Finally, the provision of a compact antenna test range enables the firm to conduct OTA testing of large antennae even in small spaces.

Said Peng Cao, Vice President and General Manager, Wireless Test Group, Keysight: “(We are) pleased to provide DSP Research with 5G test solutions specifically designed to ensure that cellular devices comply with regulations relating to cellular protocols and RF interference” that can help vendors, test houses, and mobile operators improve test productivity and accelerate 5G commercial roll-outs.
