Making Wireless Work

“Losing the wires without losing your mind”
The demand for wireless audio is increasing, while the available bandwidth is decreasing dramatically. The FCC has auctioned another large portion of the spectrum to T-Mobile and other data service providers.  Are you up to the challenge of working with less spectrum?  Watch this short video and click on the tabs below to learn more.

For years, the available UHF bandwidth for our industry extended to 800 MHz. It was decreased to 700MHz in 2008. The FCC just auctioned another large portion of the spectrum to T-mobile and others, forcing the use of wireless mics to below 608 MHz. Our industry must cope with the loss of 84 MHz of spectrum while the demand for wireless increases. How is this possible? (Scroll down to see commencement of operation dates.)

The manufacturers have been forced to introduce equipment in new RF bands. These frequencies (wavelengths) respond differently than what we have been dealing with. This seminar will help increase the reliability of your existing wireless systems and help integrate new technologies into your current and future productions.

SynAudCon has assembled all-star staff James Stoffo, Karl Winkler, and Tim Vear to help you deal with these problems. James Stoffo works as a frequency coordinator for the Grammy Awards, Olympics, World Cup, Rose Bowl, and many others. Karl (Lectrosonics) and Tim (Shure) represent the manufacturers who make the hardware and assist their customers. They know the most common problems seen in the field.

This team teaches with enthusiasm. It is clearly their passion. The training combines lecture with active demonstrations to drive home the points.

This all-star staff will be addressing the following:

  • How do I fit more channels into a lot less spectrum?
  • How do I increase the reliability and performance of my existing wireless mic systems?
  • How to implement new technologies outside of the traditional UHF spectrum into existing systems.
  • How do I deal with interference from lighting and video walls? Read this interesting article on LED walls.
  • . How do I evaluate new wireless mic systems and components?
  • What are the most effective transmit and receive antennas?

The major topics will include:

  • Wireless Microphone Technologies
  • Equipment that works in new RF bands
  • Frequency Coordination and Band Planning
  • RF Fundamentals
  • Antenna Selection and Placement
  • FCC and Spectrum Allocation Issues
  • Site Survey and Commissioning Procedures

Important information from T-mobile and their plans to begin operations.

Letter from T-Mobile  A brief explanation of their plans.

Excel spreadsheet from T-mobile  This spreadsheet list the cities and “Commencement of Operations Date”.  (Dated 5/18/2018) Most of the timelines are in advance of the original timeline.

If you are in one of the cities or counties such affected, very soon your 600MHz wireless gear will likely be hit with overwhelming interference. In addition, at that point, the operation of your microphones will become illegal on those frequencies that T-Mobile is operating on. You may then follow new rules for operation in the new “Duplex Gap” which is the guard band between the wireless carrier’s up and down link signals. (653-663MHz). See this “FCC Final Band Plan” for further insight into the “Duplex Gap”. There is also a 2MHz slice just above channel 37 where wireless mics can operate, (also under new rules).

You are encouraged to reach out to the wireless manufacturers and others for help in understanding your particular situation. In any case, even where T-Mobile is not going on the air early, you must be below the 608 MHz service band no later than when the TV stations in your town move to their new lower channels, or July 2020, whichever comes first.

Phase Assignment Closing spreadsheet – this spreadsheet list 9 phases in which TV stations were to be moved from their current channel to their new post auction channel.

T-Mobile has deployed its 600MHz spectrum in 900 US cities and towns.  Here the list.

Quote from James Stoffo.

The next 3 years will present greater challenges to the wireless microphone and intercom operator than in any 3-year period in the history of man-made radio on the planet. Wireless manufacturers are responding by introducing new wireless technologies in alternate radio spectrum. The hardware used to implement this technology will require new and innovative antenna systems and accessories. The SynAudCon Making Wireless Work course will teach the strategies and techniques required to implement and master wireless audio operations well in to the future.

After working as a field technician for Vega Wireless Systems, he founded Professional Wireless Systems, which continues to be among the top wireless audio providers in the US. James has worked as the Frequency Coordinator for many high profile special events including the World Cup, NBA All-Star game, NBA Finals, and the Rose Bowl. He has also served as the frequency coordinator for the Society of Broadcast Engineers.
James has also worked as the Wireless Microphone and Intercom operator on many large special events including fourteen consecutive Super Bowls, numerous Latin and English Grammy Awards, every Latin and English Billboard Music Awards since 2000, Video Music Awards, Soul Train Awards, and Country Music Awards. James designed the wireless audio systems for Microsoft Studios, most of the Cirque Du Soliel shows in the US, the NBC Sports Facility in Stamford Connecticut, numerous theme parks and attractions, and the QVC shopping Network, a 250,000 square foot facility with multiple studios on one combined antenna system.

Tim VearTim Vear is a native of the south side of Chicago (Go White Sox!). A lifelong interest in both entertainment and science has led to the field of audio as his choice for combining these interests in a useful way. Prior to joining Shure he worked as an engineer for recording, radio, and live sound, and operated his own recording studio and sound company. He continues to play music professionally. Tim holds a BS degree in Aeronautical and Astronautical Engineering, with a minor in Electrical Engineering, from the University of Illinois, Urbana-Champaign.

He has been active in product and applications education for Shure customers, dealers, and installers, as well as company staff. His major goal has been to increase the understanding of quality audio by presenting technical information in a way that is thorough but still very accessible. Tim’s particular emphasis is on the contribution of proper selection and technique for both wired and wireless microphones.

In addition, Tim has done technical presentations for many industry organizations (NAB, NAMM, AES, and SBE), as well as for US government entities such as the White House Communication Agency and the US Air Force. Through his international assignments he has been fortunate to be able to deliver presentations in more than twenty countries and on all but one of the continents (still waiting for an offer from Antarctica ). He has provided specific applications assistance to various performing artists including the Rolling Stones and U2 and for theme parks such as Disney and Universal Studios.

While at Shure, Tim has authored several educational booklets including Selection and Operation of Wireless Microphone Systems and Audio Systems Guide for Houses of Worship.
