The FCC officially decided in January to clear the "white space" that exists at the 700 MHZ frequency for particularly designated usage. While the FCC fielded arguments from big cellular and broadcasters in determining white space authorization, "unauthorized users" of microphones operating on a 700 MHZ frequency were depicted as "squatters" and intruders, since many have, technically operated in this space illegally for years. Unfortunately, this may have a serious impact on venues that use wireless microphones. Theaters, concert halls, stadiums, and others, will no longer be able to use technology that uses the 700 MHZ frequency. The FCC is giving organizations that use mics on the 700 MHZ frequency until June 12 to transition to another frequency.
This means that you need to know if this is something you need to know. This could be hugely expensive to organizations that have equipment that operates at this frequency. If nobody in your organization knows this, or knows where the equipment manuals are, you can check the FCC's website.
If you find that your equipment will have to be replaced, try contacting the manufacturer and/or the retailer where it was purchased. Some companies are being very good about offering discounts on new equipment or switching out the old free of charge, according to sources at a conversation at Arts Advocacy Day.
