The Overview
Viavi Solutions’s OneAdvisor-800 is an all-in-one cellular site test tool with comprehensive capabilities for cell-site deployment, including:
· Fiber inspection and characterization
· Cable and antenna analysis
· Open RAN (O-RAN) radio verification (when upgraded with the O-DU Emulation application).
Who Needs It and Why?
Service providers and equipment manufacturers worldwide are adopting open radio-access networks to reduce infrastructure costs and lower the barrier to entry for new product innovation. In line with these benefits, O-RAN also enables carriers to thoroughly validate the tower installation very early in the process, thereby reducing installation problems and accelerating deployments. Viavi’s OneAdvisor-800 cell site test tool brings the company’s savvy in O-RAN specifications development and wireless lab validation platforms to bear on the field requirements for getting 5G sites up and running.
Under the Hood
OneAdvisor-800 is a single, modular instrument that helps cell-site technicians test fiber, radio frequency (RF), and Common Public Radio Interface (CPRI), eliminating the need for multiple independent tools. The addition of the Open Distributed Unit (O-DU) Emulation application further streamlines site verification and guards against future site visits by technicians by enabling functional testing of the Open Radio Unit (O-RU) upon installation, rather than waiting until the O-DU is in place. The technician’s work is simplified by guided workflows, with Job Manager programming the service provider’s test criteria, and automatically uploading results to the StrataSync cloud.
With its modular design philosophy, the OneAdvisor-800 is, in a sense, future-proofed. The addition of O-RAN radio verification through the O-DU Emulation application is an indication of Viavi’s commitment to support the entire network lifecycle.
Viavi’s comprehensive test platform for lab validation, field deployment, and service assurance of O-RAN networks is able to validate that all interfaces are working correctly—including RF, O-DU, O-RU, signaling, transport, timing, and synchronization—and equipment is performing to specifications even under load and stress, from the lab to the field. Viavi also helps network operators ensure interoperability—a key concern in a multi-vendor-based O-RAN environment.
