ITU Resolution Benefits Wireless Microphone Operators

Joe Ciaudelli, Sennheiser’s director of spectrum affairs, was selected to be a member of the U.S. State Department delegation to the international Radiocommunication Assembly, leading the effort to enact Resolution ITU-R 59, which could prove highly beneficial to future wireless microphone operations.

Joe Ciaudelli, Sennheiser’s director of spectrum affairs, was selected to be a member of the U.S. State Department delegation to the international Radiocommunication Assembly, leading the effort to enact Resolution ITU-R 59, which could prove highly beneficial to future wireless microphone operations. Here is his report:

Every three to five years, government delegations from around the globe gather at the Radiocommunication Assembly and World Radiocommunication Conference conducted by the International Telecommunications Union—the United Nations specialized agency for information and communication technologies.

This year these events, designated RA-19 and WRC-19, took place from October 21 to November 22 in Sharm El-Sheikh, Egypt.

A primary issue at RA-19 was Resolution ITU-R 59. Calling for harmonization of radio frequency bands used for electronic news gathering and related content, Resolution ITU-R 59 is the fruit of a multiyear collective effort by audio industry manufacturers, associations and thought leaders.

With their support, Sennheiser has been active in the relevant ITU working parties during the past four years leading up to RA-19/WRC-19, documenting the exponential growth of news and entertainment programming during this era when radio frequency spectrum available for wireless microphones has been constrained.

Within the U.S. ITU delegation, many practical solutions developed through industry collaboration with the Federal Communications Commission were integrated into ITU reports and recommendations. These include allowing wireless microphones to operate in suitable alternate frequency bands and refining regulations that factor in realworld conditions, such as permitting wireless microphone transmission on channels used for TV broadcast if the local terrain or building shielding makes such operation feasible. These efforts were reinforced in Europe through the ITU delegation from Germany and the Association of Professional Wireless Production Technology.

The United States is the undisputed leader in TV/radio broadcasting, motion pictures, professional sports, performing arts and other live cultural events. Copyrighted programming contributes well over $1 trillion to the U.S. economy, supports more than 5 million high-paying jobs, and has the highest export-to-import ratio of any American made product or service. Wireless microphones are indispensable tools that fuel this ecosystem.

In promoting Resolution ITU-R 59 in particular, the fact that electronic news gathering is an essential service during emergency situations such as natural disasters was emphasized. At such times wireless microphones are the front-end of a broadcast chain that delivers life-critical information to the public. Regional and global harmonization is essential for cross-border spontaneous newsworthy events and will benefit any production team that operates internationally.

The U.S. proposal for Resolution ITU-R 59 was vigorously debated during the Radiocommunication Assembly, with points raised by many administrations including the Russian Federation, Japan, Germany, United Kingdom and Australia. In the end, the proposal from the United States was ratified with only minor edits. Resolution ITU 59-2 now instructs the ITU to post a publicly accessible database of links to the relevant regulatory information regarding wireless microphones from the U.N. member nations. It also calls for charts and other documentation that will aid in harmonization of permitted frequency bands among countries.

The next step is to encourage other countries to contribute their information for inclusion in the ITU database. The ITU only accepts information about a country if it comes directly from that country’s administration. Wide international participation throughout the four-year study cycle leading up to the next RA and WRC in 2023 will be a key element to harmonization.

Toward that goal, an informational technical paper was presented through the U.S. State Department delegation to the conference of the Inter-American Telecommunications Commission that took place in August. CITEL is a regional coalition for North, Central and South America that forms ITU proposals with consensus from the Americas. It’s noteworthy that Canada recently finalized a proceeding that largely harmonizes wireless microphone operation with the United States, including portions of the 941.5–960 MHz band. Also, an invitation to provide the information for the ITU database was distributed to the member nations attending WRC-19.

This is all part of a grassroots effort by a wide variety of stakeholders within the content creation industries. Milestones such as this resolution would not have been achieved without the backing of individuals and associations who included their names in industry petitions or, better yet, wrote to the FCC, the State Department or their elected officials directly.
