Near an installation that will take place later this week, experts from US airlines have again said that 5G can disrupt flights of various types. The reason is simple: according to who has been in this sector for a considerable time, the spectrum of C band of fifth-generation connections is very close to the frequency used by aircraft altimeters. That is, there is a risk that we will see cases where 5G brings down planes. 5f1m3q
A Reuters had access to a letter signed by CEOs from several companies in the airline sector asking, once again, that the installation of the towers 3,2 km from the airport's runways does not happen. Understand the case right now and how this can also affect Brazil, which should have 5G networks in all its capitals and the Federal District by July.
Sensors may malfunction 3s3y57
As you can imagine, planes have several sensors essential for flights to be carried out as safely as possible. To guarantee the title of the safest means of transport in the world, one of the most important sensors is the altimeter. As the name says, this object is used to measure the plane's altitude in relation to the ground.
Everything was running smoothly, but the airline professionals from EUA warned that, in fact, 5G can disrupt flights for a simple reason: the frequency of these networks is extremely close to that used by altimeters.
While the plane's sensor operates at 4,2 GHz and 4,4 GHz, the C band that were acquired at auction by AT&T and Verizon operate at a frequency of 3,98GHz. With work being postponed to January 19th (yes, next Wednesday), a new letter has been sent to:
- Brian Deese: Director of the White House National Economic Council;
- Pete Buttigieg: US Secretary of Transportation;
- Steve Dickson: of the Federal Aviation istration (FAA);
- Jessica Rosenworcel: President of the Federal Communications Commission (FCC)
The CEOs claim that a catastrophic crisis that “could lock tens of thousands of Americans abroad” is bound to ensue if the facility is actually carried forward.
Unless our main hubs are cleared to fly, the vast majority of the travel and transport public will be essentially on land. This means that on a day like yesterday, more than 1.100 flights and 100.000 engers would be subject to cancellations, detours or delays. To be blunt, the country's trade will stop.
Letter signed by airline CEOs on installing 5G networks
The document calling for immediate intervention was signed by companies such as UPS Airlines, Atlas Air, JetBlue Airways e FedEx Express. The letter was organized by Airlines for America. In addition to the possible unusability of altimeters, low visibility flights by the same implementation of 5G networks are also expected to be affected.
Companies do not want to prevent installation 3o4r5i
There is a lot of talk about how 5G networks will change how we live today, especially talking about the Internet of Things (IoT) in sectors such as the connected home and even agriculture. But the big problem is that with great technology, great problems are also coming. That's what the experts point out.
Imagine that with the risk of sensors not working correctly, the goods that, for example, through or are even manufactured in the EUA, will take longer to get here (or not at all). the alert of CEOs is not focused on preventing 5G networks from being deployed in the US, but rather making them stay away from the area where planes .
We expect 5G to be rolled out everywhere in the US except within the approximately 3,2 km of runways at some major airports. Immediate intervention is required to avoid significant operational disruptions to air engers, carriers, supply chain and delivery of needed medical supplies.
Letter signed by airline CEOs on installing 5G networks
The same letter also points out that other problems may arise with the deployment of 5G networks. At an auction last year, the AT&T e Verizon, major US operators, won the right to place towers after paying US$ 80 billion (about R$ 442 billion). The installation would now take place on January 3, but this was postponed by two weeks after market experts had already staged the protest.
A FAA allowed the installations to be carried out, but the towers designed to be in areas closer to the airports could not be placed in the planned location. However, the list of places where the planes depart did not include major airports.
45% of the commercial aircraft fleet are allowed to perform low visibility flights, in the same place where the towers will be installed now on the 19th. The responsible operators claim that the amount of energy does not impact the operation of the sensors.
Update at 14:24 pm on January 19: Following the release of the letter signed by the CEOs of airlines, the operators agreed during Tuesday, January 18th to limit the installation of Band C towers and delay the installation in locations close to US airports.
A number of planes were allowed to land 5e151w
On January 19, around 17 pm, the FAA carried out a review on three altimeters of some models that need to fly as soon as possible for operations to continue working. A new portion of aircraft received clearance to perform landings even with the installation of 5G networks.
As of January 16, only 45% of the US commercial fleet was authorized to take off. The list has been updated and now, 62% of the commercial fleet may be making low visibility landings at airports. The types of Boeing type aircraft 777 are the big news on the list. Are they: 717, 737, 747, 757, 767, 777, MD-10/-11 and Airbus A300, A310, A319, A320, A330, A340, A350 e A380.
Delta Air Lines considers flight cancellations 5j282r
Even with operators postponing installations once again, the Delta Air Lines disclosed that there are still chances of flights being cancelled, especially talking about weather on flights with low visibility. The company points out that before leaving home with plans to board the planes, customers consult the app. Fly delta, which is available for Android e iOS.
In case of cancellation due to the mentioned reasons, the company guarantees exemptions for customers, not being necessary to make any payment to make the appointment. Even the rescheduling of the flight will be done automatically by the system so that customers can schedule. Flight status information will be sent via email and an in-app self-service tool Fly delta e official website of the airline are available.
Can 5G disrupt flights in Brazil? 27l1h
As soon as the experts EUA alerted the possible problem of 5G connection towers in the USA, many people were left wondering if the same problem could happen in Tupiniquin lands. THE EMBRAER, a Brazilian transnational conglomerate, came to comment on the case. The big difference between the operators of the EUA and Brazilian operators is that the frequency here is 500MHz lower, which leaves the proximity between altimeters and 5G networks aside.
5G in Brazil is at least 500 MHz away from the operating frequency of these equipment, while in the US this distance is just over 200 MHz. This greater distance in frequency, called guard band, leads to better conditions for coexistence, and less risk of interference in Brazilian territory.
Moisés Moreira, advisor to the National Telecommunications Agency (Anatel) and president of the Monitoring Group for the Implementation of Solutions for Interference Problems (Gaispi)
Operators that won the Brazilian auction can operate at up to 3,7GHz. Altimeters operate at a frequency that varies between 4,2 GHz and 4,4 GHz. O Brazil stays away from this problem precisely because it has the “guard band”, which serves as a space created to generate more security.
As much as the problems may not happen, the EMBRAER continues to monitor with the ANATEL to end damage to the Brazilian air market. In-flight and ground tests to check for possible interference are being considered.
