Understanding what spectrum is available to you in a given area and how Ofcom is managing the spectrum is critical to achieving successful productions. Anyone who owns gear in the 700MHz band as well as below 694MHz will be affected by this clearance. To see how the clearance might affect spectrum in your area, refer to Ofcom’s 700 MHz planner. (Details are subject to change, but it’s a pretty good indicator).

Those who take the time to understand spectrum policy and regulation will be best placed as engineers to work within the RF environment post clearance. Additionally, the government is in discussions with the industry to agree on compensation packages for affected users. Therefore, it stands without saying that it’s in your interest to understand potential compensation options.

Wireless microphones are critical to modern production values, but it’s those with a genuine understanding of how to efficiently deploy and coordinate world-class wireless setups that will truly lead the next generation of events. Ultimately, a larger pool of qualified well-versed engineers will help to mitigate some of the potential issues that a more crowded, post 700MHz world will throw at us. To help equip engineers with the knowledge they require, Shure regularly run best-practice training and workshop programmes through the Shure Audio Institute (follow the link to register for upcoming events near you.

One side benefit of a continuously decreasing RF landscape is that it does encourage manufacturers to innovate. Next-generation digital wireless systems (such as Shure QLX-D, ULX-D, and Axient Digital) are all great examples of how wireless tech has stepped up to the challenge. And while digital wireless alone is not a magic bullet answer to spectrum congestion, it’s absolutely true that a well-engineered, linear and robust digital wireless system is more spectrally efficient than its analogue counterpart. For example, with Axient Digital, we can place more than three times the number of frequencies per MHz than with its analogue counterpart. In HD (High Density) mode, we can take this spectral efficiency even further by up to three times this amount once again.

In the grand scheme of things, digital wireless mics are a fairly new development, and while there is a small learning curve, it’s critical that we as engineers stay on top of the tools available. Ultimately, a solid understanding of new wireless tech, fundamental RF principles, and upcoming changes to spectrum are the best ways for any engineer to prep for a future post 700MHz.
