Brand's Modular Fiber Links, Multiband Receivers and Long-range RF Help Chief RF Comms Engineer With Demanding Cycling and Marathon Broadcasts

When live cycling races and international marathons stretch for miles across cities and countryside, there is no margin for RF failure in live broadcast. As Chief RF Communications Engineer at Gravity Media, Glenn Willems is responsible for ensuring flawless, long-range RF communication in some of the most demanding live broadcast environments in the world, so that the events reach viewers without interruption. These productions often require communications links spanning extraordinary distances, sometimes placing the RF team more than 100 miles away from the action.

Throughout the racing season, which runs from February through October, Willems and his team support major cycling events such as the Tour of Italy, Tour of Denmark and numerous international marathons, including those in Berlin, Vienna, Amsterdam and Rotterdam. To meet these challenges, Willems frequently turns to Wisycom, integrating a range of the company's RF over Fiber and wireless solutions into Gravity Media's workflows. The wireless part of the communication is absolutely critical, Willems explains. It's all live television, so our broadcast simply has to work.

Wisycom solutions often play a role in creative, problem-solving scenarios, such as during the Berlin Marathon, where Willems was tasked with enabling a reporter to conduct live interviews while riding a bike alongside runners. It was a rather particular request, he laughs. We had to find a way to get that wireless microphone signal into our transmission system while everything was moving.

The solution involved using Wisycom MCR42 camera receivers, integrated directly into the video link system. If you looked at it, you might realize we weren't operating like a professional scripted TV or film production team, he admits, but it worked extremely well. That's the kind of outside-the-box thinking we often need, and Wisycom made that possible. Thanks to the MCR42's multiband and multi-compatible capabilities, we were even able to integrate third-party microphones without issue. That flexibility meant we could adapt quickly, which is crucial in live broadcast environments.

Beyond wide-ranging racing applications, Gravity Media also regularly relies on Wisycom for large-scale and non-traditional infrastructure deployments, where the brand's MFL RF over Fiber system has proven especially valuable. The MFL is a modular system, so you can really mix and match and configure it the way you like, Willems explains. That flexibility is a huge benefit, especially for environments like concerts, large events or complex outside broadcasts.

The Gravity Media team also deployed the MFL system on a major stadium installation, where the TV compound was seven- to eight-hundred meters from the field of play. Doing that with traditional wireless intercom methods would have been cumbersome and very expensive, adds Willems. With MFL, it turned out to be a very cost-effective way to get the job done. The system, which links the OB vans to the field of play via fiber, has now been operating reliably for several years. It just works great.

Across all applications, Willems consistently points to reliability as the deciding factor. When you're working outdoors in wind, rain and constantly changing RF conditions, you simply cannot afford failure, he says. Reliability is of utmost importance and Wisycom delivers.

He also emphasizes Wisycom's RF over Fiber approach as a major advantage for long-distance coverage. Fiber virtually has no losses, which means every fraction of a dB is preserved, he continues. That directly translates into range and stability. For us, every fraction of a dB counts. As long as your connectors are clean, fiber is also plug-and-play. People think it's black magic, but it's actually incredibly robust.

Having known Wisycom for more than 15 years-both as a former technical sales engineer and now as a user-Willems says the brand continues to impress. The quality, flexibility and reliability always amaze me, he concludes. In live TV and major events, that combination is exactly what you need. Wisycom consistently delivers, and that's why it has become such a trusted part of my RF toolkit.
