(AP Photo\/Sue Ogrocki, File)<\/span><\/figcaption><\/figure>U.S. telecom companies and airlines have been fighting for weeks over the potential impact of 5G wireless<\/a> services on aircraft, in stark contrast to the rollout of new-generation services elsewhere, which has broadly gone ahead without airing new safety concerns.

Here is some background on the dispute, in which Verizon Communications<\/a> and AT&T agreed on Monday to a two-week delay in using newly acquired wireless spectrum, drawing back from a standoff that threatened to disrupt flights. The agreement promises to avert most, but not all, potential disruption to air travel from 5G<\/a> deployment

WHAT IS THE PROBLEM?<\/strong>

The U.S. auctioned mid-range 5G bandwidth to mobile phone companies in early 2021 in the 3.7-3.98 GHz range on the spectrum, known as C-Band, for about $80 billion.

U.S. aviation industry<\/a> groups in recent months stepped up concerns and the Federal Aviation Administration (FAA) issued a formal warning in November of the risk of interference with flight equipment.

In the airline industry, radar altimeters, which measure altitude, operate in the 4.2-4.4 GHz range and there are concerns that there is not a big enough buffer from the frequencies to be used by the telecoms companies.

The companies have faced pressure from the White House, airlines and aviation unions to delay the deployment amid concerns about potential interference of 5G with sensitive aircraft electronics like radio altimeters.

WHY IS THAT POTENTIALLY IMPORTANT FOR AVIATION?
<\/strong>
Radio altimeters help to minimize the risk of accidents or collisions by giving an accurate reading of the proximity to the ground. The readouts are also used to facilitate automated landings and to help detect dangerous currents called windshear.

WHAT DIFFERENCE DOES THE FREQUENCY MAKE?
<\/strong>
In short, the higher the frequency in the spectrum, the faster the service. So in order to get full value from 5G, operators want to operate at higher frequencies.

Some of the C-Band spectrum auctioned in the United States had been used for satellite radio but the transition to 5G means there will be much more traffic.

IS THIS A PROBLEM ELSEWHERE?
<\/strong>
Following years of international<\/a> discussions, the European Union in 2019 set standards for mid-range 5G frequencies in the 3.4-3.8 GHz range.

They have been auctioned and taken into use in many of the bloc's 27 member states so far without issue.

The European Union Aviation Safety Agency (EASA), which oversees 31 states, said on Dec. 17 the latest discussion was specific to U.S. airspace. \"At this stage, no risk of unsafe interference has been identified in Europe,\" it said.

AT&T and Verizon have agreed to adopt exclusion zones around many U.S. airports similar to those used in France for six months.

FAA officials noted the spectrum used by France (3.6-3.8 GHz) sits further away from the spectrum (4.2-4.4 GHz) used for radio altimeters than in the United States and France's power level for 5G is also much lower than what is authorized in the United States.

But Verizon said it will not use spectrum that closer than what France is using for several years.

In South Korea, the 5G mobile communication frequency is 3.42-3.7GHz band and there has been no report of interference with radio wave since commercialization of 5G in April 2019.

Currently, 5G mobile communication wireless stations are in operation near airports, but there have been no reports of problems.

CTIA, a U.S. wireless trade group, said in a filing with the Federal Communications Commission that \"wireless carriers in nearly 40 countries throughout Europe and Asia now use the C-Band for 5G, with no reported effects on radio altimeters that operate in the same internationally designated 4.2-4.4 GHz band.\"

It added \"each day U.S. aircraft, carrying thousands of U.S. citizens, land in these countries without incident and with no expression of concern by the FAA or foreign aviation regulators. This is the classic dog that did not bark. The laws of physics are no different in the United States than in Europe or Asia.\"

But airlines had warned that without an agreement the safety precautions could disrupt up to 4% of daily flights. An airline group said the issue had the potential \"to divert or cancel thousands of flights every day, thus disrupting millions of passenger reservations, causing substantial disruptions.\"

United Airlines Chief Executive Scott Kirby said last month that left unresolved the interference issue would mean that at major U.S. airports in the event of bad weather, cloud cover or even heavy smog \"you could only do visual approaches essentially.\"

做5 g电信对航空安全构成威胁?

在航空业,雷达高度计测量高度,在4.2 - -4.4 GHz范围和有人担心没有一个足够大的缓冲区的频率使用的电信公司。

美国电信公司和航空公司一直在争取周的潜在影响5 g无线服务飞机,与此形成鲜明对比的是,推出新一代服务在其他地方,已广泛地向前走没有播出新的安全问题。

广告
的争议,这是一些背景威瑞森通讯和美国电话电报公司(AT&T)周一同意为期两周的延迟使用新买的无线频谱,画从一个僵局,威胁要扰乱飞行。协议承诺避免大多数,但不是全部,航空旅行的潜在破坏5克部署

这个问题是什么?

美国拍卖中档5 g带宽来移动电话公司在2021年初在3.7 - -3.98 GHz范围,称为c波段,为约800亿美元。

美国航空行业集团最近几个月加大关注和美国联邦航空管理局(FAA) 11月发出正式警告干扰飞行设备的风险。

在航空业,雷达高度计测量高度,在4.2 - -4.4 GHz范围和有人担心没有一个足够大的缓冲区的频率使用的电信公司。

公司面临来自白宫的压力,航空公司和航空工会推迟5 g的部署在担心潜在的干扰与敏感的飞机电子像无线电测高计。

为什么是潜在的重要航空?
无线电测高计有助于减少事故的风险或碰撞给一个准确的阅读的接近地面。读数也用于促进自动着陆和帮助检测危险的电流称为风剪。

广告
什么不同的频率?
简而言之,频谱的频率越高,越快的服务。所以为了获得5 g的全部价值,运营商希望工作在更高的频率。

在美国的c波段频谱拍卖已用于卫星广播但过渡到5克意味着将会有更多的交通。

这是一个问题在其他地方吗?
在多年的国际讨论,欧盟在2019年为中档标准5 g在3.4 - -3.8 GHz频率范围。

他们已经拍卖和纳入使用在许多欧盟的27个成员国迄今为止没有问题。

欧盟航空安全署(EASA认证),负责31个州表示,在12月17日最新的讨论是针对美国领空。“在这个阶段,没有不安全的风险干扰已被确定在欧洲,”它说。

AT&T和Verizon已经同意采用禁区周围许多美国在法国机场类似用于6个月。

联邦航空局官员指出法国使用的频谱(3.6 -3.8 GHz)坐在远离频谱(4.2 -4.4 GHz)用于无线电测高计比在美国和法国的功率5 g也远低于授权在美国。

但Verizon表示,不会使用光谱,近比法国使用好几年了。

在韩国,5 g移动通信频率是3.42 - -3.7 ghz的乐队,没有干扰无线电波报告自2019年4月5 g的商业化。

目前,5 g移动通信无线电台都在机场附近的操作,但没有报告的问题。

CTIA,美国无线贸易集团,在提交给美国联邦通信委员会表示,“无线运营商在近40个国家在欧洲和亚洲现在使用的c波段5 g,没有报道影响无线电高度计在指定相同的国际经营的4.2 - -4.4 GHz的乐队。”

每天补充说“美国飞机,带着成千上万的美国公民,这些国家的土地没有事件和表达式由联邦航空局或外国航空监管机构的关注。这是典型的狗不吠叫。物理定律是一样在美国比在欧洲或亚洲。”

但航空公司警告说,如果不达成协议的安全措施可能会扰乱多达4%的每日航班。航空集团表示这个问题”有可能转移或取消每天成千上万的航班,因此扰乱数以百万计的旅客预订,造成实质性的破坏。”

美国联合航空公司首席执行官斯科特•柯比上月表示,尚未解决干扰问题就意味着美国主要机场的恶劣天气,云层浓雾笼罩,甚至“你只能做视觉方法本质上。”
