Rules & regulations

Audio visual equipment of all types has the ability to cause disrupting interference to communications services. To ensure the quality of experience for all exhibitor and attendees, and general services within the Event, exhibitors are required to eliminate any possible source of interference from within their stand space.

The CE marking (formerly the EC mark) is a mandatory conformity for all equipment installed at the event (video walls, computers, tablets, etc.). This mark is a minimum requirement, with part of the certification process to reduce likelihood of disruptive radio frequency interferences. This standard does not however guarantee that a given piece of equipment will not cause harmful interferences; this remains the responsibility of the exhibitor. In dense environments, such as an event, even minor issues can have a disproportionately large effect. For prototype equipment or demonstrations that require the use of licensed spectrum, please refer to the Wireless Policy: Cellular Frequencies.

All exhibitors who intend to install a video wall larger than ten square meters must send the make and model details, and relevant CE certification, to the following email address: mwcbarcelona.internet@firabarcelona.com. Exhibitors must specify if the video wall will be used permanently or occasionally during the Event. Certifications should also be provided for the equipment that is used to drive the main screen (Video Matrix, controllers etc.), as these can also emit signals that can cause interference.

The Organisers or its designated representatives may check that video wall installations have the relevant  CE marking, as well as if the equipment is radiating across in any protected, licensed or requested band, causing detrimental interference to others. In all cases the exhibitor will be required to take immediate action to rectify.

Recommendations to reduce interference:

• Use of superior quality cables and wiring/installation methods
• The shielding of cables and power sources of any equipment that may cause interference to communication services, such a power sources of video walls, computers, etc.
• Non-modification of any electrical equipment as this can lead to generation of interference and invalidate the CE certification
• The Organisers reserves the right to measure and evaluate signal emissions from any equipment and if found to be causing interference, even if carrying a CE mark, will require immediate rectification or the shutdown of the source of interference
