Experts Call for Spectrum Allocation Reform, Pointing to C-Band Clash Between Airlines and 5G

Although the wireless and aviation industries’ fight over mid-band spectrum has been largely resolved, regulators and experts from both industries agree that the allocation process should be updated in preparation for future disputes.

The challenge for regulators is to balance the “importance of more spectrum for the commercial industry to allow a critically important technology, 5G, to expand… against the equally important issue of, we can’t have airplanes falling out of the sky because their altimeters are being interfered with,” said Lawrence Strickling, former administrator at the NTIA, at an Information Technology & Innovation Foundation event on Monday.

The disagreement between the two industries peaked in January 2022, when the Federal Aviation Administration warned that the safety concerns surrounding major wireless carriers’ planned 5G rollout would lead to widespread flight delays and cancellations — causing an “economic calamity,” according to the leading airline industry association.
