Streamline training and testing when you deploy the VIAVI portfolio of fast, accurate instruments for base station installation, commissioning, and maintenance. And harness the intelligence in your network to assure services, protect revenue, deliver automated network performance and optimization, and enable analytics.

CellAdvisor Cable and Antenna Analysers provide integrated solutions for line sweep measurement, RF / optical power measurements, and fibre inspection, in a lightweight, cloud-enabled instrument ideal for cell site installation.

The majority of problems in wireless networks occur at the base station infrastructure, composed of the antenna system, cables, and connectors, and they are typically related to the cable feed-line (coax or fiber). Contamination in fibre connectors is the most common problem associated with Fibre. All wireless networks with fibre based feed-lines require the verification of both RF and Fibre. Until now multiple instruments were used for these tests, one for RF and another for fibre, and the JD720C series cable and antenna analyser is the first cable and antenna analyser that provides an integrated solution for fibre and coax, being the most versatile and optimal instrument to properly service and install cell sites.

InterferenceAdvisor

Identifying and rectifying interference issues in a mobile environment is a challenging but critical task. Mobile users near the interference source will experience degraded call success rates, increased dropped calls, decreased battery life, poor voice quality, and reduced data throughput. Detecting, locating, and finally eliminating sources of RF interference is critical to maintaining good user experience throughout the network.

VIAVI InterferenceAdvisor™, our fully automated interference hunting solution, is the most user-friendly solution available today. Simple to set up and completely intuitive, InterferenceAdvisor allows one RF engineer to easily identify and locate an interference source with minimal effort: voice prompts simply direct the engineer to the source of interference. What used to take days to troubleshoot can now be done in hours by following a few simple steps.

InterferenceAdvisor is versatile tool that can help in isolating all types of RF interference for common cellular channels.

Highlights:

  • Automated interference area indication and navigation guide
  • Voice prompt guides the driver to the estimated interference location
  • Built-in accessories minimize cabling requirements
  • Cable-free Android tablet with WiFi connection
  • Spectrum control display allows for detailed signal monitoring
  • Gated sweep control and display for TDD interference hunting
