ADI, Keysight team on OpenRAN

Analog Devices (ADI) and testing specialist Keysight Technologies work together on a test bench for new OpeRAN radio systems

The two companies are developing a test bench to check the interoperability of a new OpenRAN radio device (O-RU), which includes a PHI physical layer of ADI basebands, a transceiver, defined software, power and a clock integrated with an Intel FPGA. Keysight’s emulation, signal generation and signal analysis capabilities with Open RAN will be used in a wide range of applications, improving the testing process, reducing testing complexity and time.

The two see the telecommunications industry moving to disaggregated and virtualized radio access network (vRAN) architectures, which are expected to account for more than 10 percent of the total radio access network market by 2025, according to the Dell-Oro Group.

“As a result of combining our technologies, tools and design resources, ADI and Keysight are able to provide the O-RAN ecosystem with a robust platform for rapidly developing reliable O-RUs,” said Joe Barry, vice president of wireless communications at Analog Devices. . “Working together, we offer our customers the fastest way to develop a cost-effective, energy-efficient and interoperable O-RAN O-RU.”

“We are pleased to align our resources with ADI, a leader in O-RU technology solutions, to help service providers realize the full potential of O-RAN specifications,” said Kailash Narayanan, Keysight’s Vice President and CEO. Commercial Communications Group. “Keysight and ADI offer technology and test solutions that create an effective bridge between the radio and the core network, leading to accelerated interoperability development and testing.”

The infrastructure, based on the open interfaces of the O-RAN Alliance, allows mobile operators to create a stable network environment with different providers for a wide range of 5G applications. Validating O-RU performance and testing interoperability between network elements from the edge of RAN to the 5G core (5GC) allows mobile operators to effectively deploy different OpenRAN technologies in 5G networks with different providers.
