Wireless RF Coordination

The more wireless microphones, IFBs and in-ear monitors there are at a location, the easier it is for them to interfere with each other or with outside signals. RF coordination scans the UHF spectrum (470–900 MHz), calculates compatible frequencies and keeps them monitored throughout the shoot. Felix Castillo is a radio frequency technician trained by Shure Audio Institute and has coordinated RF outdoors for Exatlón and Survivor.

What your production gains

  • No RF dropouts or noise

    Frequencies calculated to avoid intermodulation between the production's own gear and interference from television and other services.

  • Scales to many channels

    Frequency plans for productions with dozens of simultaneous wireless mics, IFBs and communications.

  • A plan per location

    Every location has a different spectrum: it's scanned and the plan is adjusted before rolling.

How we work

  1. 01

    Transmitter inventory

    A list of all the production's wireless equipment, ours and other departments'.

  2. 02

    Spectrum scan

    Measuring the UHF spectrum at the location to identify occupied channels and noise.

  3. 03

    Calculation and assignment

    Calculating compatible frequencies and intermodulation, and programming each device.

  4. 04

    Monitoring during the shoot

    Watching the spectrum during production and reassigning if interference appears.

Frequently asked questions

Which band do you work in?

UHF between 470 and 900 MHz, the band used by professional wireless microphone and IFB systems.

Do you coordinate other departments' equipment?

Yes. Coordination is only useful if it includes everything that transmits on set: camera, video, communications and sound.
