The FAA has issued a final rule requiring aircraft radio altimeters to tolerate 5G interference, ending a four-year dispute between wireless carriers and aviation. The rule, coordinated with the FCC's new spectrum auction, mandates fleet retrofits (estimated $4.49 billion) across two deadlines, offset by an FCC rebate programme.
◆ ◆ The Wire takeaway
If you make avionics, cockpit displays or flight-critical sensors, you have a mandated customer base with a four-billion-dollar retrofit bill and two locked deadlines—and the FCC just cleared the way for wireless carriers to start densifying near airports. The real prize is not the retrofit; it's selling the next generation of interference-immune instruments to every operator buying today.
