Frequency Coordination

View All Glossary Terms

Definition

Frequency coordination is the step between deciding to deploy a professional radio system and actually programming the radios. It involves analyzing the existing frequency landscape in a specific geographic area to identify which licensed frequencies are already in use by other organizations, then selecting available frequencies that do not conflict with existing licensees. In densely populated areas like South Florida — where radio spectrum is heavily utilized — frequency coordination is technically complex and requires access to FCC database tools and industry coordination resources. Coordination is required before submitting an FCC license application and before programming radios for any professional deployment. Repeater systems require separate frequency coordination from the handheld radio fleet.

Frequently Asked Questions

Frequency coordination identifies available licensed radio frequencies in your specific geographic area before programming or FCC license application. Without it, you risk deploying on frequencies already licensed to another organization — creating mutual interference and a regulatory violation. Professional coordination eliminates this risk.
Yes. SEI performs all frequency coordination for rental deployments as part of their standard service. Clients do not need to manage the FCC database or licensing process. SEI handles the full licensing and coordination workflow for both handheld radios and repeater systems.
Frequency coordination should be completed well before programming begins — ideally at least 3 to 4 weeks before an event for a standard deployment. For events in heavily used spectrum areas like South Florida, additional lead time is advisable. SEI builds this into the rental timeline automatically.

Why It Matters

Deploying a radio system on frequencies already licensed by another organization creates interference — potentially disrupting both operations. This is both an operational problem and a regulatory violation. Professional frequency coordination before deployment prevents interference and ensures FCC compliance from day one.

How SEI Wireless Solutions Uses It

SEI performs frequency coordination for every professional radio deployment — both sales and rentals. For rental events in South Florida’s dense radio environment, frequency coordination is particularly critical and complex. Clients never need to manage this process themselves — it is built into SEI’s deployment service.
