WMSA Highlights the Critical Need for Wireless Spectrum at Major Events

The Vital Role of Wireless Microphone Spectrum in Major Events

As the world gears up for high-profile events such as the Super Bowl 2026, FIFA World Cup, and the 2028 Olympics, the issue of wireless microphone spectrum allocation has come to the forefront. The Wireless Microphone Spectrum Alliance (WMSA) has shared critical insights into how essential the available spectrum is for these events, which demand flawless operation and superior audio quality.

Spectrum Demand for Major Events

Wireless microphones are integral in facilitating live performances, announcements, and broadcasts that touch millions globally. The massive scale of these events translates into a pressing need for radio frequency (RF) spectrum to accommodate numerous wireless channels. With hundreds of wireless channels required just for talent, crew, and officials at events like the Super Bowl, the spectrum requirements continue to grow.

The WMSA has been advocating for the protection of dedicated spectrum to ensure uninterrupted wireless operations during these grand events. The coalition consists of manufacturers, audio engineers, and broadcasting professionals who aim to raise awareness with key entities such as the FCC, Congress, and the White House on the critical need for access to sufficient spectrum.

Coordinating the Spectrum

To manage the complex RF landscape during such events, Game Day Coordinators (GDCs) play a pivotal role. They allocate the spectrum resourcefully, prioritizing different operations, from venue management to the requirements of teams and broadcasters. Given the hyper-competitive and high-stakes nature of these events, interference mitigation techniques become crucial. Professional audio engineers employ methods like multiplexing and frequency planning to prevent signal clashes and ensure seamless operation.

The Threat of Insufficient Spectrum

However, the WMSA is sounding the alarm over the current state of the spectrum available for wireless microphones. The U.S. spectrum in the 470–608 MHz band, which is crucial for wireless microphones, is being shared increasingly with broadcasters and other entities, leading to diminishing availability.

Scans across various U.S. cities have shown that the spectrum landscape has changed drastically since the incentive auctions in 2017, resulting in limited or nonexistent available TV channels for wireless microphones. This situation has required many event organizers to seek Special Temporary Authority (STA) grants from the FCC, a process that is not only unpredictable but also inadequate for long-term planning.

In the absence of reliable spectrum access, medium to large-scale events might become unviable in many cities, threatening both public performances and potential revenue streams. The WMSA indicates that high-profile events surrounding the upcoming Olympics will see an overwhelming percentage of their audio links operating within the 470–694 MHz range, highlighting the urgent need for expansion in accessible spectrum.

Collaborations for a Sustainable Future

WMSA has engaged in dialogues with the FCC and various organizations to work toward securing additional spectrum and preserving existing allocations. Their focus is strategically aimed at supporting both current and future needs, particularly as attention shifts to commercial 6G uses that may encroach upon the existing TV-UHF band crucial for wireless microphones.

The challenge of ensuring sufficient availability for these operations is compounded by the growing demand for live events, which not only create thousands of skilled jobs but also contribute to an economic output exceeding two trillion dollars globally. Supporting the creative industries also encourages innovation, showcasing culture not just locally but on a global scale.

In conclusion, as the landscape of major sporting and cultural events evolves, the necessity of robust spectrum access for wireless microphones cannot be overstated. The WMSA continues to advocate passionately for the preservation and expansion of this crucial resource to ensure that live events can proceed with the exemplary audio quality that audiences expect and have come to love.
