OneAdvisor 800 Wireless Platform

All-in-One Cell Site Installation and Maintenance Test Platform


The VIAVI OneAdvisor 800 has been elegantly designed to verify and troubleshoot radio access networks of all types, from private 5G networks, to land mobile radio networks, to legacy networks still providing great service. The OneAdvisor 800 leverages multi-functional architecture, covering different test applications, scaling, and adapting to many different user groups, including:

Radio Construction: All test aspects of the transmission lines of any cell site are quickly tested with OneAdvisor 800: validate coaxial cable, antennas, as well as fiber characterization and inspection

Radio Operation: Easily verify a radio’s transmission according to 3GPP standards, maintain a radio’s power level and coverage, as well as the ability to identify and locate multiple types of signal interference.

OneAdvisor 800 Interference Finder


  • Easy PIM Detection.  All bands with one device, non-customer impacting test, and all from the safety of the ground.  
  • Over-The-Air Sync and Timing. Remove the hassle of connecting to a network port to take network timing measurements. The OneAdvisor 800 is the first field-test device to perform fast OTA timing and sync analysis of 5G cell sites.
  • Easy Interference Analysis. With value-added features like TDD Automatic Gated Sweep (TAGS), the OneAdvisor 800 enables non-experts to confidently use a spectrum analyzer.  For example, TAGS automatically identifies the correct uplink time-slot format, then isolates the interfering signal.
  • Blind Scanner. Allows an engineer to step into an unknown RF environment and quickly identify the active channels in use whether LTE, DSS, or 5G, drastically cutting time at the site.  
  • Fiber Test. Critical elements in today’s mobile network, OneAdvisor 800 tests the cleanliness of fiber end-point connections as well as the integrity of a fiber cable with one of multiple VIAVI OTDRs that pair with it. 
  • X-Haul. With the same device, a technician can also test the transmission effectiveness of the wired network, whether fronthaul, mid-haul, or the high-capacity backhaul.
