Rules & Regulations

To ensure availability and fairness of allocation, there are restrictions on requesting frequencies for the Event. Exhibitors should contact Fira Barcelona to discuss any requirements.

There are a limited number of frequencies available to be shared by the exhibitors.  As a result the frequency coordination team will coordinate the different slots to reduce interference between exhibitors.  Power restrictions may also apply.

It is necessary to apply in the following circumstances:

• The equipment intended for demonstration will broadcast a radio frequency at any band other than Wi-Fi spectrum (2.4 – 5 GHz – 6GHz (EU band)).
• When planning to use wireless microphones and walkie-talkies. This type of equipment requires band allocation and coordination to avoid interference between exhibitors, even though they can be used in unlicensed bands without requesting a frequency band.
• For using wireless microphones it is recommended to secure a frequency, to avoid interference.
• It is NOT necessary to apply for a frequency when using a commercial SIM card from an operator or for Wi-Fi devices.

Ordering process:

• Contact the Frequency Coordination team of the Event at the following email address mwcbarcelona.frequency@firabarcelona.com, with the requirements.
• If ordering microphone frequencies contact the Microphone Coordination Team of the Event at mwcbarcelona.mics@firabarcelona.com with the requirements.
• Exhibitors must report both wired and wireless demonstrations even if demonstrations use licensed/unlicensed spectrum.
• Once your request is approved, a spectrum allocation fee needs to be paid through the Fira Store. For each frequency band requested, one unit of Frequency Management Fee product must be ordered. For Microphones the fee includes a pack of 6 units of Mics.
• The product is under Internet & Connectivity > Internet equipment & additional services > Frequency Management Fee / Microphone Frequency Management.

If you need help during the process, please contact  +34 93 233 3099 or email mwcbarcelona.frequency@firabarcelona.com

Important notes:

• The deadline to order cellular frequencies is Friday 29 January 2027.
• The deadline to order microphone frequencies is Friday 12 February 2027.
• We recommend the use of professional digital microphones within the bandwidth ranges permitted by current Spanish regulations.
• We do not recommend the use of analogue microphones. In high-density multi-venue coordination, we cannot guarantee sufficient free spectrum space for this type of transmission.
• List of non-recommended microphones:
  • Sennheiser EW G2/G3/G4
  • Shure SLX
  • Shure ULXP

• If you need Wi-Fi or use Wi-Fi bands, please refer to the Wireless Policy: 2.4 GHz / 5 GHz / 6Ghz (EU band). 
• The demonstrations cannot interfere with other licensed telecommunication services.
• Each exhibitor must be in condition to control the emission power of their radio equipment during any time that the spectrum is in use (including build up and validation testing, etc.).
• The maximum e.i.r.p limits stipulated in Appendix 1 will be applied.
• The assigned frequencies will be confirmed around Tuesday 23 February 2027, with the official confirmation from the Spanish Frequency regulator around Tuesday 16 February 2027.
• A time scheduling policy would be applied if there are not enough frequency bands.
• Assigned frequencies can be used from Monday 1 March 2027 to Thursday 4 March 2027.
• All the emissions must finish at the end of the Event.
• Please note that there is a specific advice section on how to coordinate and set up your audio-visual equipment to avoid interference with other systems. Exhibitors can find this information in the Audio Visual Frequencies Interference section in this manual. Please click here to view this section.
