6 GHz Automated Frequency Coordination (AFC)

Enabling unlicensed access to the 6 GHz band by coordinating shared spectrum between Standard Power Access Points (SP) and incumbent Point-to-Point microwave.

In April 2020, the FCC opened 850 MHz of spectrum in the 6 GHz band for unlicensed usage. Since then, the unlicensed 6 GHz band has been a boon for networks needing additional spectrum—but it must be carefully managed. To avoid interfering with licensed incumbent point-to-point devices, Standard Power devices operating in unlicensed frequencies are required to check an automated frequency coordination (AFC) system prior to operating. The AFC system uses FCC-provided data (ULS data) of all licensed incumbents currently operating in the 6 GHz band and coordinates shared spectrum use between them and the unlicensed operators.

While all AFC system providers must be approved by the FCC, they are not all equal with regards to performance. Differences in system architecture, interference analysis parameters, and design and data quality have significant impacts when it comes to user experience. Selecting the right AFC system matters.

CommScope’s Comsearch AFC system is the result of nearly five decades of experience in microwave frequency coordination and expertise with cloud-enabled, data-centric dynamic spectrum management systems. In addition to the FCC’s 6 GHz user database, our AFC solution also accesses Comsearch proprietary databases, which contain exhaustive information on incumbent system configurations developed over the years. Our proprietary interference analysis and frequency coordination engine enables seamlessly coordinated co-existence between unlicensed Standard Power users and incumbent point-to-point microwave users in the 6 GHz band.


Long-term experience with frequency coordination minimizes mistakes made by newer AFC providers.

  • Comsearch AFC system is the result of nearly 50 years of dynamic spectrum management experience.
  • Proprietary databases are among the most comprehensive in the industry.
  • Comsearch AFC system incorporates industry-standard interference analysis and mitigation technologies.


Superior spectrum/interference management means more available spectrum and more satisfied users.

  • Comsearch AFC system accesses the FCC Universal Licensing System at least once daily to receive updates.
  • Added use of Comsearch proprietary databases increases spectrum availability at higher powers and channel availability.
