The Federal Aviation Administration is investigating the cause of mysterious GPS interference that, over the past few days, has closed one runway at the Dallas-Fort Worth International Airport and prompted some aircraft in the region to be rerouted to areas where signals were working properly. The interference first came to light on October 17 when the FAA issued an advisory warning  flight personnel and air traffic controllers of GPS interference over a 40-mile swath of airspace near the Dallas-Fort Worth airport.

These days, there isn’t a lot of harmony in the world of technology policy. But there is a bright spot of bipartisanship in a section of our airwaves: the 5.9 GHz band. In 2020, the Federal Communications Commission voted unanimously to modernize the rules in this spectrum to allow both Wi-Fi and automotive safety tech to operate. This win-win was celebrated by proponents of car safety and broadband alike. But now the Department of Transportation (DOT) is working on a study that may purposely have been designed to undo this decision.

The Arizona Commerce Authority, in partnership with the Arizona Department of Transportation (ADOT), announced the Arizona Statewide Broadband Middle-Mile Strategic Plan, which supports current broadband expansion efforts on Interstate 17 and Interstate 19.

President Joe Biden donned the jersey of Team Delay by making it clear he had pushed for airlines to get more time to account for certain kinds of legacy aviation equipment. “What I’ve done is pushed as hard as I can to have the 5G folks hold up and abide by what was being requested by the airlines until they could more modernize over the years, so 5G would not interfere with the potential of a landing,” Biden said.

The Federal Aviation Administration (FAA) issued new approvals that allow an estimated 62 percent of the US commercial fleet to perform low-visibility landings at airports where wireless companies deployed 5G C-band. The new safety buffer announced January 18 around airports in the 5G deployment further expanded the number of airports available to planes with previously cleared altimeters to perform low-visibility landings. The FAA early January 19 cleared another three altimeters. Even with these approvals, flights at some airports may still be affected.

Several international airlines canceled some US-bound flights after American wireless operators and aviation officials were unable to fully resolve a months-long standoff over the launch of new 5G signals. AT&T and Verizon agreed to temporarily water down expansion plans for 5G wireless service to address air-safety regulators’ concerns about the network signals’ effect on aircraft instruments.

The Federal Aviation Administration picked dozens of airports that would get buffer zones to help avoid expected flight disruptions once a new 5G wireless service goes live in Jan 2022. The 50 airports include hubs for major US passenger airlines such as Chicago’s O’Hare International and Dallas Love Field. They also include airports prone to fog and clouds, like San Francisco International and Seattle-Tacoma International. The FAA, which manages U.S.

Industry lawyers and consultants predict the recently enacted $1 trillion infrastructure measure is likely to create more investment opportunities for private-equity firms in areas they already favor, such as telecommunications, while doing little to expand their presence in the government-dominated transportation sec

The explosion of the internet of things (IoT) is enabling communities across the globe to evolve into smart cities. Leveraging sensors, networks and data analysis, communities are addressing challenges in health care, energy, the workforce, public safety and many other sectors. But what’s behind the pulse of the smart city? Fiber infrastructure serves as the veins that support emerging applications, such as smart traffic sensors, connected vehicles and modern, cloud-connected medical devices.

The Arizona Department of Transportation (ADOT) has been laying fiber optic conduit along a 46-mile stretch of I-17 between Flagstaff and Sedona (AZ) as part of a project to bring broadband internet access to rural communities in the state. The broadband initiative is made possible by a partnership between ADOT and the Arizona Commerce Authority. The project will create more affordable opportunities to provide rural communities in Arizona with high-speed internet service.
