US safety regulators have received more than 100 pilot reports of possible interference from 5G wireless signals -- including three near Chicago O’Hare International Airport -- since the new mobile phone service began less than two weeks ago. The reports of anomalies on aircraft devices known as radar altimeters are being reviewed by the Federal Aviation Administration (FAA). Interference from the new 5G service has been ruled out in many of the cases, and it remains unclear whether the others indicate a safety hazard or just pilots being overly cautious.

Leading telecommunications and aviation trade groups have agreed to share data in an effort to resolve a tense standoff over a new 5G service that threatens to disrupt flights. The groups said in a joint statement that they would exchange “available data from all parties to identify the specific areas of concern for aviation.” The statement was issued by CTIA, which represents the cellular industry, Aerospace Industries Association and Airlines for America.
