capabilities for O-RAN conformance with Open Fronthaul interface
control, as well as user, synchronization, and management planes.
By utilizing Keysight KORA O-RU Test Suite with Keysight’s new Time
Sync Analyzer, we have fully validated our O-RU technology for the
O-RAN market.”
Jaiseo Park, Director of Mobile Access R&D Group,
HFR Inc., said: “HFR my5GTM provides an optimized End
to End Private 5G solution to fulfill customer's digitalization. We
participated in the O-RAN Fall 2023 Global PlugFest event with our
O-RU currently operated in a real site by HFR my5GTM solution and
we also checked interoperability with a third-party vendor. As for
O-RU conformance test perspective, we’ve done not only for
C/U/M-plane but also for S-plane as well using one single test
equipment, Keysight Time Sync Analyzer. It helped us to validate
our O-RU efficiently.”
Constantine Polychronopoulos, GVP 5G & Telco Cloud,
Juniper Networks, said: “Juniper Networks and
Keysight engaged in joint effort with leading industry partners to
show the capabilities of Traffic Steering with E2 and Energy
Savings with O1. These use cases are priorities of interest to the
Operator community globally, and once again we demonstrate how
O-RAN is moving the industry forward. Events like the O-RAN
PlugFest and the associated collaborations reflect Juniper
Networks’ commitment to the success of O-RAN.”
