Radio Frequency Coordination for Live Events

Presented by
John (JC) Coulter
The Seattle Center Sound Department
The Pacific Northwest Section of the AES

Monday, April 18, 2016, 7:30pm
The Art Institute of Seattle, South Campus, Room 767-768 (usual place on the top floor)
Directions to the meeting venue.

It's 2016 now, and more than six years since the auction of the 700mHz band. Wireless devices have been pushed into an even more congested area of the former UHF TV Spectrum, and a few new areas have opened up as well. The FCC isn't done yet, and the 600mHz band is about to be auctioned off. Don't ignore that our government is really hard up for money.

With more and more productions demanding wireless everything, frequency coordination becomes a very necessary part of any large event, especially if TV is involved. Some issues:

  • How to coordinate a large number of wireless microphones, in-ear monitor systems, and intercom systems.
  • How to evaluate the radio frequency spectrum at a particular location in order to accomplish the above.
  • How the radio frequency spectrum can be very different at different times at a specific location, with a specific long-term example.
  • The current auction attempt by the FCC to re-allocate the radio frequency spectrum (the 600mHz band), the current status of that ongoing auction, and its potential effects 3-5 years in the future which could completely change the available spectrum for wireless systems used in live performance.

Please join us on Monday, April 18th for an enlightening and engaging presentation. Bring your questions!
