The tracks of Spa Francorshamps are legendary to motorsports fanatics. Its famous La Source curve has challenged numerous racing legends in Formula 1, and the annual “24h” are a true phenomenon among racing connoisseurs. To bring the action of the races even closer to the audience a reporting crew broadcasts all action in real time from the pit lane and workshops. On the road with wireless microphones, they need an excellent audio system. And that’s where FACE made Shure Axient take the pole position.
Shure Axient takes pole position at Spa Francorchamps

It’s no secret that Formula 1 is an industry where investing in top technology can make the difference. Technology is not only present to boost the performance of engines - F1 is an industry leader when it comes to modern media as well; from the comfort of their couch, F1 fans can follow the races on television with multi-camera video scenario’s, cockpit view and live coverage of the teams. However, true fanatics know that there’s nothing like the real thing; watching the race from the stands, feeling the rumble of the engines, as close to the action as you can get…

In order to bring an even better experience to the visitors of the Spa Francorchamps race track, a mobile reporting crew covers all the inside action in the pit lane and from the team workshops. The reporters hit the road with wireless microphones and look for interesting facts, scoops and bring interviews of the pilots and their crew. In case of calamities, they can assist in handling interventions or evacuations.

While going for interesting stories the reporters were bumping into a couple of obstacles however:

Extremely crowded RF-spectrum in and around the pit lane

The tech support teams of the various race teams as well as the ENG-teams are using many microphones, in-ears, intercom systems and telemetry. The available spectrum was almost completely lavished with that many devices. Secondly, the pit lane is several hundred metres long and the steel constructed garage boxes are anything but “RF friendly”.

A forest made of antennas - The available spectrum is almost completely lavished with devices

External interference and the famous “Plan B”

Reporting in real-time from the pit lane is challenging for the crew. Interference is to be avoided at all times, especially when the wireless mics are needed in time of calamities. With this in mind, Spa Francorchamps chose for an excellent solution with the Shure Axient wireless system, in combination with Wisycom antennas.

The Shure Axient systems are automatically, and in real time, calculating which frequencies are available and deploy them to the Axient transmitters and receivers easily and efficiently. For additional flexibility in complex RF environments, this system monitors and ranks a live list of backup frequencies. The backup frequency ranking evaluates the quality of the backup frequencies and determines which are the most usable. When the system detects risk of interference it automatically hands out the best backup frequency to handheld transmitter(s) and receiver(s) alike, allowing fully synchronized switching, without human intervention, using the Showlink wireless network.

Seamless, uninterrupted audio

The Shure Axient system allows working in a frequency diversity mode which ensures seamless, uninterrupted audio for mission-critical transmitters in complex RF settings. The system is able to receive audio from a single source on two independent frequencies and uses the signal from both frequencies to provide optimized audio on a single channel. The risk for drop outs will be reduced to virtually zero.

Glenn Willems, Account Manager at FACE explains: “The selectivity and the excellent intermodulation behaviour of the Axient transmitters and receivers, in combination with the bullet-proof Wisycom headend amps (IP3 = +40 dBm), ensure that interference due overload, adjacent channel transmitters and intermodulation products can be avoided.

 When we tested the system in this critical environment, it turned out that even on the edges of the requested coverage area, we were able to obtain more than 25 dB of fading margin using a clever antenna configuration.

 Additionally, the Axient systems allow us to program any frequencies that are reserved, for example for television of radio coverage. Which are then automatically excluded.”

Bottom right - The Axient system ensures that reserved frequencies are exluded automatically, and only licensed frequencies are used
