Keysight Technologies has announced that Zillnk (Sichuan Hengwan Technology Co. Ltd) has selected its Open RAN (O-RAN) Studio software to complete radio unit (O-RU) conformance validation in downlink (DL) and uplink (UL) based on specifications published by the O-RAN Alliance.

Zillnk, a provider of advanced antenna system technology and radio units, uses Keysight’s O-RAN test systems to validate the performance and interoperability of network elements across protocol and RF domains. This helps Zillnk accelerate development of macro and small cells aimed for deployment in disaggregated, open, multi-vendor heterogenous networks. Keysight helps an ecosystem of O-RU vendors, such as Zillnk, develop systems that mobile operators deploy to deliver advanced connectivity services for enterprises, smart cities and factories.

“Keysight’s in-depth expertise in the O-RAN standards and end-to-end O-RAN test help Zillnk verify open end-to-end wireless 5G new radio (NR) base station systems prior to final integration with end-customers’ systems,” said Robby Liu, founder and general manager of Zillnk.

Open RAN Studio software, part of the Keysight’s integrated portfolio, from the edge of the radio access network (RAN) to the 5G core (5GC), was launched as the industry’s first O-RAN distributed unit (O-DU) emulation software for validating O-RUs.

Keysight contributed to the second global Plugfest event organized by the O-RAN Alliance with a wide range of 5G radio access network (RAN), 5G core (5GC) and 5G NR air interface test systems. The results of the event highlight the readiness of the O-RAN standard and will help accelerate deployment of multi-vendor O-RAN compliant network infrastructures. Many mobile operators are in the process of deploying networks using an open RAN architecture to support flexible upgrades and quickly launch new services such as industrial IoT (IIoT) applications.
