Keysight: smooth migration from 4G LTE networks to 5G Open RAN

Posted 20 August 2021

Keysight Technologies announced it joined forces with Xilinx and Cisco to showcase fronthaul solutions that support a smooth migration path from traditional 4G LTE networks to 5G open radio access networks (O-RAN).

Multi-vendor radio access network (RAN) deployments based on open standard interfaces defined by the O-RAN Alliance require thorough end-to-end validation across radio frequency (RF) and protocol domains, as well as from the physical to the application layer. Keysight offers integrated hardware and software O-RAN solutions that enable a diverse ecosystem of vendors and mobile operators to quickly verify performance, interoperability and compliance to the O-RAN specification of each network element and end-to-end.

“Keysight is working with Xilinx and Cisco to support the development of 4G and 5G solutions that share the same fronthaul network, enabling mobile operators to cost-effectively migrate to 5G open RAN deployments,” said Giampaolo Tardioli, vice president and general manager of Keysight’s network access group. “Our demonstration underscores the robustness of O-RAN specifications by bringing together Keysight Open RAN Architect solutions with Xilinx’s O-RAN compliant radio unit (O-RU) and Cisco’s fronthaul gateway, supporting both common public radio interface (CPRI) and O-RAN fronthaul interfaces.”
