Smooth Sailing: 5G Signals Cause No Flight Disruptions Near Airports

Despite concerns about potential disruptions caused by new wireless 5G systems near major airports, no major flight disruptions were reported on Saturday. Telecom companies had limited the power of the signals around busy airports, giving airlines an extra year to upgrade their planes. Most major U.S. airlines have made the necessary changes to adapt to 5G, except for Delta Air Lines, which still has 190 planes lacking upgraded altimeters. The potential disruptions stem from the interference of 5G signals with radio altimeters, which are critical for landing in low visibility. The Federal Aviation Administration is closely monitoring the situation and working with airlines to address any issues.

5G Restrictions on Flights: Minimal Impact Predicted, But Delays Possible

Starting this weekend, wireless providers are expected to activate new 5G systems near major airports, potentially causing disruptions to flights. While aviation groups have expressed concerns about interference with aircraft equipment, airlines have been given an extra year to upgrade their planes to protect against radio interference. Most major U.S. airlines claim to be ready, except for Delta Air Lines, which has 190 planes that still lack upgraded altimeters. The Federal Communications Commission granted wireless carriers licenses for the C-Band spectrum, dismissing interference risks, but a compromise was reached to delay the rollout of 5G signals near busy airports. Transportation Secretary Pete Buttigieg warned that flights could be disrupted if planes haven't been retrofitted, and airlines are advised to adjust schedules accordingly.

5G Airlines Deadline: Potential Disruptions and Minimal Impact Predicted

Starting this weekend, wireless providers are expected to activate new 5G systems near major airports, potentially causing disruptions to flights. While concerns have been raised about 5G signals interfering with aircraft equipment, especially radio altimeters used for landing in low visibility, most major U.S. airlines claim to be prepared. However, Delta Air Lines has 190 planes that lack upgraded altimeters due to supply chain issues, although the airline does not anticipate canceling any flights. The Federal Communications Commission granted wireless carriers licenses for the C-Band spectrum, dismissing interference risks, but a compromise was reached to delay the rollout near 50 busy airports. Transportation Secretary Pete Buttigieg warned that flights could be disrupted for planes without retrofitted altimeters, urging airlines to adjust schedules accordingly.

Photonic Time Crystal Enhances Light Amplification

Physicists have created a 2D photonic time crystal that amplifies light at microwave frequencies, which could have applications in technologies like transmitters and lasers. Unlike time crystals, photonic time crystals are artificial materials not found in nature and are not necessarily suspended in quantum states. The crystal could be used to improve wireless signals by coating devices in 2D photonic time crystals, making signal strengths more robust. The crystal only amplifies microwave frequencies, but a slight tweak in the design could allow it to work in millimeter-wave frequencies, like those used in 5G communications.
