What is the Frequency Blockchain?

This is a first-of-its-kind public sector service launched by the National frequency agency and supported by the General Company Department (DGE), which will allow to experiment a new frequency management method for frequencies subject to general authorisation - so-called "free frequencies", such as WiFi, for example - which are increasingly used for innovative purposes. These frequencies are not protected, however, and their increasing use deteriorate their operation.

The frequency Blockchain is used to support this growth by allowing players to self-organise and by anticipating their needs without the intervention of a centralised management body. It provides a transparent register of free of rights frequencies.

Who is the Frequency Blockchain for?

The use case addressed by the Frequency blockchain concerns the use of PMSE Audio frequencies during major events (Tour de France, Rolland Garros, 24 Hours of Le Mans, etc.).

It allows audiovisual and entertainment professionals to self-manage the use of audio PMSE frequencies (programme making and special events - frequencies used by equipment such as wireless microphones, for example) during major events to help prevent interference.

How is it done?

It is a simple, intuitive and decentralised platform accessible from any computer. 

1. The organisers of major events and PMSE audio frequency applicants can create their account in a few clicks.  
2. Once an event has been created by its promoter, the blockchain associates the frequency ranges that can be used by PMSE audio equipment to it. 
3. Users can declare the use of frequencies within the available ranges. 
4. Promoters and users have an instant view of the occupancy status of usable PMSE audio frequencies. 

With the Frequency blockchain, every player can immediately and transparently see how the various PMSE Audio frequencies are being used during an event.

Cartoradio is a mapping tool developed by the ANFR and used to show cell towers and the measurements of the electromagnetic fields they create on the same map. You can find Cartoradio on its website. Cartoradio uses the Geoportail tool from the National Institute of Geographic and Forestry Information.

Cartoradio gives the location of radio stations and access to the results of electromagnetic field measurements for a given site, summarised in a measurement sheet. To access the results, users enter an address or zoom in directly on the map.

Since 2021, statistics by territory provide details of mobile sites authorised and in service, with filters by technology, mobile operator and frequency band.

The OpenBarres application is a free, advertising-free tool offered by the National Frequency Agency (ANFR). It allows real-time diagnosis of the state of a mobile network open to the public.

Make your own personalised route to objectively assess the strength of your operator's signal when you're on the move (e.g. commuting). You will be able to see your route and the areas where the network signal is strong and, conversely, where it is weak. You decide when you want to record your movements. The collected data will be sent anonymously to the ANFR database. As for your journeys, they remain saved on your phone. You can control the use of your data, download it and carry out your own study. 

The OpenBarres application also makes it possible to record the field strength received by your mobile phone. An advanced export function for radio field measurements has been developed. It provides access to more technical data on networks and radio signals.

Since 2021, it is possible to record the strength of the 5G signal received by the phone. Technical information specific to 5G has been added to the "advanced" mode exports of the data recorded during your journeys.
