VIAVI Enhances its RFoFiber Technology with RFoOBSAI

Stop Climbing Towers: CellAdvisor™ Offers a Complete RF Test Solution for Fiber-Based Cell Sites with CPRI or OBSAI Protocols

July 14, 2015 — VIAVI Solutions announced today enhancements to its RFoFiber technology, adding RF over OBSAI (RFoOBSAI) analysis components of Open Base Station Architecture Initiative (OBSAI) interfaces to its CellAdvisor product family. RFoOBSAI lets technicians quickly and more affordably identify and fix signal interference problems across all types of cell sites: from conventional sites with coax feeders to modern sites with fiber links between the baseband unit and remote radio units.

The growing use of modern macro cells, small cells, distributed antenna systems (DAS), and C-RAN architectures is driving deployments of fiber-based remote radio units to achieve low latency and high bandwidth. These environments widely use CPRI and OBSAI protocols. With CellAdvisor, technicians safely and accurately test interference from the base of the cell site—without climbing a tower.

Key Features and Benefits

  • RFoO
  • BSAI — VIAVI Solutions RFoOBSAI and RFoCPRI™ technologies capture and analyze RF metrics whether the fronthaul is coax or fiber-based with either CPRI or OBSAI protocols.​
  • Engineered for fiber-based architectures — technicians capture and analyze RF components from mobiles (uplink) as well as radios (downlink) to identify interference. This ensures end users receive the highest-quality mobile service.
  • One instrument, one site visit — no other field test solution conducts cable, interference, CPRI, OBSAI, cellular signal analysis, and fiber tests in a single instrument.
  • Cloud-enabled management and analysis — VIAVI Solutions StrataSync cloud integration lets you remotely track your inventory, perform upgrades, store and share trace and configuration files, and secures and makes your data available for analysis via complimentary JDSU Viewer software.

Use Case

With the fast increase in fiber-based remote radio deployments, service providers and their contractors struggle with rising costs related to commissioning, insurance, and maintenance—as well as safety concerns due to tower climbs. CellAdvisor with RFoFiber technology effectively reduces maintenance costs and risks to the technician, providing increased efficiency and productivity by virtually eliminating tower climbs to safely and quickly manage mobile services.
