The end of the 700 MHz Debate
Posted on February 8, 2010
For 700 MHZ wireless, the end is finally near!
The deadline has been set. Finally! The FCC has made official their order regarding wireless mic systems operating the the so-called 700 MHz band. As of June 12, it will be illegal to operate wireless mics in this spectrum. This has been a drama played out over more than 10 years. It’s nice just to have a firm date. There is more background on the “why” behind this decision this morning, over at TechnoPraxis if you’re interested.
So, if you still have systems operating between 695 and 806 MHZ, what should you do?
First, if you have not already done so, it’s time to contact your dealer to replace your now obsolete systems. You can check your system on the FCC website to see if it’s covered by the new rule.

The good news is that the major manufacturers have extended their rebate programs through the end of June, so you can get some help with the financial impact of this decision.
Beyond that, expect the remaining spectrum that we are allowed to use for wireless to get a bit more congested. The FCC has stated that wireless mic usage takes priority over these new broadband devices, but only when it comes to preventing interference. If you’re operating a wireless microphone, the THEORY is that the new devices should avoid you and pick another frequency to operate on.
There will be a registration database that will allow wireless users to stake a claim for specific frequencies in specific locations. There are also ongoing tests to create workable sensing technology. The new devices will check to see if you’re operating a wireless mic before they operate on a specific frequency. We may also see the development of wireless beacons. Think of it as a wireless lighthouse. Wireless mic users will transmit a signal that will tell these new broadband devices to stay away.
Regardless of how this all shakes out, one thing is clear. The airwaves are getting more crowded, and wireless mics are expensive. You can avoid all of these problems pretty easily, by simply using wired microphones whenever possible. If the talent isn’t moving around, and moving around a lot, think wired. As my friend tp:// is fond of saying, “the cheapest wired microphone on the cheapest cable is FAR more reliable than the most expensive wireless system available.”
That is good advice.
