From Beats to Beyond:
Entropia & R&S Communications Master Communication at Diverse Events in March & April

At any large event, from a vibrant indoor concert to a sprawling city marathon, while the atmosphere is key for attendees, seamless communication is the backbone of effective control behind the scenes. Whether it's ensuring safety, managing intricate logistics, or coordinating complex production, a reliable walkie-talkie connection is absolutely crucial.

R&S Communications, powered by Entropia's robust TETRA network and ComBus Flex control room, provided essential communications solutions for a series of distinct and demanding events throughout March and April:


March Highlights: Mastering Indoor Spectacles

Masters of Hardcore (March 29th): Crystal-Clear Communication Amidst the Noise. At this high-energy event in the Brabanthallen 's-Hertogenbosch, where booming beats were the norm, reliable security communication was paramount. R&S supplied dependable TETRA walkie-talkies utilising the Entropia network, which maintained interference-free and crystal-clear audio even in the extremely loud environment. This enabled security teams to react swiftly and effectively, with ambient noise posing no obstacle to their communication.

Snollebollekes & La Fuente (March 23rd, 2025): Seamless Coordination for Simultaneous Shows. Managing two simultaneous performances demands meticulous organisation. For the combined event of Snollebollekes and La Fuente at the GelreDome, R&S Communications utilised the established Entropia TETRA network. This ensured optimal sound quality and facilitated efficient collaboration between production, security, and crew teams through reliable and interference-free communication.

Euromast Stair Climb: Vertical Coverage Achieved. This unique project presented a significant vertical communication challenge. Instead of focusing on horizontal range, our coverage needed to extend upwards. Thanks to a well-engineered network, emergency services and event organisers were able to communicate seamlessly across all 185 meters of the Euromast.


April Spotlight:
Rotterdam Marathon
Where World-Class Performance Meets Seamless Communication

The Netherlands once again witnessed why the Rotterdam Marathon holds its prestigious world-class status. In close collaboration with R&S Communications, Entropia's robust TETRA network delivered uninterrupted communication across the entire city marathon course.

R&S Communications provided walkie-talkies not only for the core organisation but also for security personnel stationed along the route, the dedicated first aiders of the Rotterdam-Rijnmond Red Cross, and the Crowd Care personnel managing flow at crucial city center metro stations.

Always a Real-Time Overview: GPS tracking provided a live feed of the first and last runners, traffic controllers, and security teams. This real-time insight allowed the organisation to know exact positions and make swift, informed decisions.

Efficient Traffic Flow Management: GPS-enabled tracking assisted traffic controllers in proactively preventing bottlenecks and safely guiding essential personnel through the city, ensuring a smooth, congestion-free path for the runners.

Rapid Incident Response Capability: In critical situations, every second is crucial. Thanks to precise GPS tracking, the nearest security or first aid responder could be instantly located and dispatched, significantly enhancing the safety of both spectators and runners.

Enhanced Behind-the-Scenes Coordination: Organisers benefited from an at-a-glance view of their team locations, enabling more efficient task allocation and overall coordination.
