Competition
venues and other relevant premises under Paris 2024 spectrum management. |
The Games of the XXXIII Olympiad and the Paris 2024 Paralympic Games (“the Paris 2024 Games”) will be held from 26th July to 11th August 2024 and from 28th August to 8th September 2024, respectively.
The competitions will be held mainly in Paris (the host city of the Games and capital of France) and its neighbourhood, like Saint-Denis, Le Bourget, Nanterre, Colombes, La Courneuve, Vaires-sur-Marnes, Versailles, Saint-Quentin-en-Yvelines and Élancourt. However, other major cities are associated to this event such as Marseille, Lyon, Bordeaux, Nantes, Toulouse, Saint-Etienne, Lille, Nice and finally Teahupo’o in French Polynesia.
The Paris 2024 Organising Committee for the Olympic and Paralympic Games (hereafter Paris 2024) is responsible for planning, organising, financing, and delivering the Paris Olympic and Paralympic Games in 2024. To this end, and with regard to issues related to spectrum use, test, tagging and monitoring of radio equipment, it closely works with two separated entities:
1 The first one is the Agence nationale des fréquences (ANFR) which is responsible for the radio spectrum management in France, and in particular of the frequency planning, and the radio site management and
2 the Autorité de régulation des
communications électroniques, des postes et de la distribution de la presse
(Arcep) which is in charge of regulating electronic communications in France.
According to the French legislation, Arcep is responsible for delivering the spectrum authorizations under the general authorization regime or the individual authorization regime. Usually, the ANFR delivers, on behalf of Arcep, temporary frequency use authoriations for PMR and, as appropriate, for audio/ video Programme Making and Special Events (PMSE). For the Olympic Games (OG) and Paralympic Games (PG), all authorizations will be notified to the applicant by Paris 2024.
To ensure a safe and reliable spectrum environment, the ANFR will test, and tag all the radio equipment during the Games at the competition venues and other relevant venues (hereafter named Venues) except the ones defined in Section 1.6. The ANFR will ensure the radio spectrum monitoring and if needed the enforcement during the Paris 2024 Olympic and Paralympic Games (OPG).
At the same time, the ANFR will continue its spectrum management activity near the Olympic and Paralympic Venues and manage spectrum requests from spectrum users.
To anticipate the spectrum needed for the Paris 2024 OPG, the ANFR and Paris 2024 studies are based on the data from the past Olympic and Paralympic Games as well as other major international sport events, considering technological evolutions. The bands made available for the Paris 2024 OPG and presented in this Guide take into account the status of currently assigned spectrum in France.
As to the spectrum assignment, the ANFR should ensure to avoid harmful interference not only among the radio systems operated by the stakeholders involved in the Games, but also between the systems operated by the stakeholders in the Games and other radio systems already in operation nationwide. To avoid such harmful interference, Paris 2024 and the different stakeholders shall also conform to the applicable French spectrum regulations. In case of non- this regulation, penal sanctions can be applied.
Thus, the objective of this document is to define the spectrum management plan and clarify the spectrum assignment conditions.
Paris, the host city, and its suburbs gather 16 % of the French population and most of the head offices of the main companies established in France, and there is accordingly already a very high use level of radio spectrum. Also, 5G deployments are reducing the bands historically allocated to the PMSE usages.
The main competition venues are located less than 10 km from the athletes’ village and are concentrated in small areas. This situation induces difficulties related to the re-use of the spectrum.
For
the above reasons, Paris 2024 strongly requests the stakeholders involved in
the Games to use a wired communication system wherever and whenever possible,
in particular for microphones and cameras. The radio spectrum shall be used
only when the wired communication system cannot operationally be used.
In addition, attention is drawn on the fact that equipment using spectrum under general authorization (a.k.a licence exempt bands) operate without protection from interference and are not allowed to create interference to individually authorised spectrum users.
Nobody shall operate in Venues any radio equipment or make any use of radio frequencies, without obtaining an individual temporary authorization, or a temporary general use authorization as defined hereafter.
At the Paris 2024 Games, Paris 2024 will obtain the individual temporary authorizations from the ANFR / Arcep for the benefit of the stakeholders involved in the Games.
In order to avoid harmful interference, spectrum coordination between radio equipment used by stakeholders and existing radio equipment will be ensured.
Radio equipment using the specified spectrum under the general authorization regime, including Wireless LAN, will also have to be declared and duly authorised by Paris 2024 in order to avoid the risk of potential interference.
It should be noted that devices operating under the general authorization regime could be interfered by other stations unrelated to the Games operation. All equipment, with the exception of those mentioned in section 1.6, will be tested and tagged prior any use in Venues.
According to the frequency tables hereafter, all radio equipment shall comply with the applicable European harmonised standard (exceptions may be allowed on a case-by-case basis for Licence Exempt wireless release trigger service). The usage is allowed on a non-interference and non-protection basis.
The following wireless services that will be deployed during Paris 2024 Games are subject to temporary authorisation:
· Private Mobile Radio (Land Mobile Radio, Handheld Radio (Walkie-Talkie))
· Telemetry/Telecommand
· Talk-back System (Intercom)
· Wireless Microphones and In Ear Monitor
· Wireless Camera and mobile airborne video links
· Microwave fixed point to point link
· Microwave transportable point to point link
· Permanent and Transportable Satellite Earth Station
· Wireless LAN (Access Point)
· Wireless Release Trigger
· Other Services
All equipment shall operate according to the conditions given in the temporary authorisation delivered.
Regardless of licenses already obtained in France, all radio equipment used within the Venues requires a temporary authorization notified by Paris 2024 at the following exceptions:
· Mobile phones, tablets and connected watches, smart bracelets, Bluetooth headsets and other wearable smart devices
· Wireless file transmitter
· Wireless release trigger, see section 2.10 for the authorized bands
In any case: the use of those devices as Hot-Spots or for tethering will be strictly forbidden.
Some equipment is strictly forbidden in and around the Competition and non-Competition Venues:
· Jammer. You are notified that article L33-3-1 of the French Postal and Electronic Communications Code, prohibits the installation, possession and use of any device intended to make inoperative electronic communications devices of all types, both for transmission and reception.
· Wireless release trigger using 315 – 317.5 MHz band.
· Licence exempt walkie-talkie using 351.16 – 351.38 MHz band.
In addition, wired connection to printers shall be used (no Wi-Fi communication).
The spectrum plan with detailed information is presented below by applications. This latest publication presents the conditions for the use of radio equipment, considering existing frequency assignments in metropolitan France and French Polynesia. The coordination constrains result from the deep cohabitation studies performed by ANFR and French governmental assigning authorities.
Spectrum users should carefully plan their spectrum requirements, and Paris 2024 strongly recommends the use of cable as much as possible, in order to optimize the radio resource allocation.
In any case, applicants must adopt systems that conform to European standards1 for the smooth coordination and assignment of temporary authorisation.
Private Mobile Radio (PMR) is used by many Olympic family entities, for communication activities. This includes private security services, sport team services, National Olympic Committees, transport, Venues management, ceremonies, catering, spectator services and ticketing. Other PMR users will include partners, MRH, and Paris 2024’s suppliers. Except for the talk-back systems, the mainly voice-based PMR is expected to use a press-to-talk simplex system.
The VHF and UHF bands suitable for PMR already have a considerably high number of users in and around the Paris area. These bands are expected to be assigned to the talk back system and telemetry and telecommand at the Paris 2024 Games.
The use of digital PMR systems is recommended rather than analog systems due to the spectrum efficiency they provide. However, the digital system generates an audio delay of about 100 ms to 500 ms. Analogue radios will still be used by key user groups if such delay is unacceptable for the user’s operations.
Paris 2024 and ANFR encourage spectrum users to request assignments in the VHF band.
A Private Push To Talk based on the 3GPP on LTE network is deployed on venues for Paris 2024’s operational needs in order to free spectrum.
Following, we define two sub-services in PMR:
Land Mobile Radio refers to the mobile communication equipment and its relay equipment (repeater/base station) with multiple users for terrestrial data or voice communication (Direct Mode Operation / Duplex) but does not include the handheld walkie-talkie without repeater/base station.
Handheld Radios refer to the walkie-talkie that is not used in repeater/base station mode, or other point-to-point voice (Direct Mode Operation / Simplex) communication equipment with the same working mode as the handheld walkie-talkie.
Table 1 shows the detailed information regarding the available frequency bands assigned to PMR for the Game’s needs.
The transmission power may vary by usage, but high power shall be avoided from the viewpoint of effective spectrum usage. Transmission power should be preferably no more than 1W or maximum 5W in exceptional cases.
If the preferred frequency is not available, an alternate frequency will be assigned from the frequency range tuneable with the radio.

Talk-back system is used primarily by broadcasters for communication between the director of activities and the members of the production team such as presenters, interviewers, reporters, camera operators, sound operators, lighting operators and engineers.
Talk-back system in the PMSE-UHF band is allowed under restricted output power. Pre-set frequencies cannot be accepted as well.
The frequency bands identified for Private Mobile Radio (PMR) (see section 2.1) are to be considered for frequency assignment for the purpose of implementing talk-back systems (see Table 5).

As modern solution, Digital Enhanced Cordless Telecommunications (DECT) systems are more and more used in event management to provide a wireless global radio access for various intercom services. Given the use of DECT services by Paris 2024 in all competition venues, these services will be authorized if the compatibility with the Paris 2024 usage is ensured.
Radio Equipment shall conform to technical standards in Europe and operated in the spectrum in table 6 requires a temporary general use authorization from Paris 2024 to be used in the venues, in order to avoid the risk of potential interference.

Wireless Microphones are mainly used by broadcasters or event organizers to capture interviews, conference talk, music or ambiances. They can be handheld or body worn, with integrated or body-worn transmitters.
It is also anticipated that the demand for spectrum for Wireless Microphones at music concerts or theatres in and around the Paris area will increase during the Games.
Considering the above, Paris 2024 and ANFR requires the following to avoid the difficulty of assigning frequencies for Wireless Microphones as much as possible:
· Use wired microphones whenever and wherever possible.
· Wireless Microphones shall be used only when wired microphones cannot be used.
· Avoid using Wireless Microphones whenever possible, especially in outdoor areas.
· Use digital Wireless Microphones systems that are usually more tolerant to interference.
· Use strong filtering and dedicated frequency range antenna to reject any high level of the noise floor.
In Ear Monitor (IEM) includes equipment used for staff’s one-way receiving of live broadcast or command and dispatch or for entertainers to listen to on-site sounds.
IEMs are mainly used by broadcasters, Paris 2024 or event participants to listen to their own voice or mixed feedback on-site sounds. It usually uses broadcast transmission mode, and the signals are received by the wireless headset worn in the ear.
Considering the above, Paris 2024 requires the following to avoid the difficulty of assigning frequencies for wireless IEMS as much as possible:
• Avoid using Wireless IEMS whenever possible, especially in outdoor areas.
• Use digital Wireless IEMS systems that are usually more tolerant to interference.
• When it is possible, do not exceed more than 4 IEM transmitters at the same transmission location to avoid any intermodulation product issue.
Other services, such as audio description and mass cast are considered as Audio PMSE systems and use frequencies identified in the following section.
2.4.3. Frequency bands for wireless microphones and
IEMs services
Wireless microphones/IEMs require a channel with a bandwidth of 100 – 200 kHz which is wider than other sound transmission, and therefore the spectrum bands to be assigned for those purposes are limited.
The spectrum bands usually assigned for wireless microphones/IEMs in France are White Space (WS) and guard bands of mobile phones. In WS, many of the bands are used by DVB-T and DAB+. Therefore, it would be extremely difficult to assign a frequency that does not overlap frequencies used for DVB-T and DAB+ to wireless microphones and IEMs services.
Table 7 shows detailed information regarding possible frequency bands assigned to wireless microphones and IEMs services as a function of the area of use.
