Keysight is to develop an OpenRAN test bench using ADI’s PHY and transceiver and Intel FPGA

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

The two companies are developing a test bench to verify the interoperability of a new OpenRAN radio unit (O-RU) that includes ADI’s PHY physical layer baseband chips, software defined transceiver, power and clock integrated with an Intel FPGA. Keysight’s Open RAN emulation, signal generation and signal analysis capabilities will be used on a wide range of use cases improves the testing process, reducing complexity and testing time.

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

“As a result of combining our technology, tools and design resources, ADI and Keysight are able to provide the O-RAN ecosystem with a robust platform to quickly develop reliable O-RUs,” said Joe Barry, Vice President of Wireless Communications at Analog Devices. “By working together we offer our customers the fastest path for developing cost-effective, power-efficient and interoperable O-RAN ready O-RUs.”

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

Infrastructure based on O-RAN Alliance open interfaces enables mobile operators to create a robust multi-vendor network environments for a wide range of 5G applications. Performance validation of O-RUs and interoperability testing between network elements from the edge of the RAN to the 5G core (5GC) allows mobile operators to effectively deploy different OpenRAN technologies in multi-vendor 5G networks.
