Case study: Anatel at major sporting events

Industry: Major Events

Key benefits:

  • Managing frequency assignments
  • Detecting interference
  • Geolocating malicious signals

Solutions used

  • RFeye® Node 20-6 with Outdoor Kits
  • Wide area monitoring and geolocation software

Summary

In 2014, CRFS supplied hardware and software to Brazilian National Telecommunications Agency, Anatel for the management of RF spectrum at the FIFA World Cup and another upcoming sporting event. RFeye Nodes with Outdoor Kits were supplied to allow wide area monitoring across various stadiums and arenas in different parts of the country. This was all managed via RFeye Site and Node apps. They were able to manage the temporary frequency assignments required for the duration of the event as well as preventing, detecting and locating any interfering transmissions.

Anatel continues to use the RFeye Nodes for spectrum management applications across the country, taking advantage of Node redeployability.

"During the event, over 50 interference cases were handled in real-time"

The challenge


This was a large-scale event across multiple cities and the volume of media and spectators in attendance would increase spectrum demand.

Proper spectrum management was vital to ensure that interfering transmissions would not compromise TV coverage or, in the worst case, lead to public safety risks if emergency communications were interrupted.

The solution


RFeye Nodes in our rugged Outdoor Kits were deployed at 152 sites for real-time monitoring and TDOA geolocation.

CRFS's state-of-the-art RFeye Site software was used to visualize locations of interference sources and manage the multi-site network.

The results


Anatel and event organizers were able to handle over 300 temporary frequency assignments and prevent over 200 potential interference cases in the run up to the event. A further 50 interference cases, which could otherwise have caused serious disruption, were handled in real time during the event.
