安裝射頻濾波器
A European Commission ruling in late November has given the green light to EU airlines to provide 5G connectivity on planes starting in June 2023.
歐盟執行委員會於11月下旬裁定，自2023年6月起，歐盟航空公司可在飛機上提供5G網路，
ruling(n.)裁決;裁定;判決give the green light准許、許可
This new decision to make cell phone data networks more accessible for passengers follows a 2008 ruling which established “specific frequencies to enable in-flight mobile communications.”
這項讓乘客可更加便利地使用手機數據網路的新決定，遵循2008年的一項裁決，該裁決確立了「啟用機上行動通訊的特定頻段」。
accessible(adj.)可接近的、容易取得的、可得到的access(v.)存取;連接(n.)存取權限
Although there are still concerns about how increased power draw from many passengers simultaneously accessing 5G antennas will affect electronic aircraft equipment, safety authorities have determined that the risk of data frequency interference with flight control systems in the EU is minuscule.
儘管仍有人擔心許多乘客同時使用5G天線所增加的功率消耗將會影響航空電子設備，但飛安相關單位已判定數據頻段干擾歐盟飛行控制系統的風險微乎其微。
simultaneously同時=at the same timeaccess(v.)連接antenna(n.)天線interference(n.)干擾minuscule(adj.)微小的;極小的=extremely small
This is because the frequency of 5G in Europe, which operates at 5 GHz and higher, provides suitable “gap spacing” above the 4.2 to 4.4 GHz range of aircraft radio altimeters.
這是因為歐洲機上5G採用5GHz以上的頻譜，在飛機無線電高度計的4.2至4.4 GHz範圍之上，提供了合適的「間距」。
frequency(n.)頻率gap spacing間距GHz=gigahertz吉赫;十億赫茲giga-千兆;十億altimeter(n.)高度計;高度表altitude(n.)海拔高度
In the US, however, this is not the case as American 5G networks operate between 3.7 and 3.98 GHz.
然而，在美國情況並非如此，因為美國5G網路在3.7和3.98 GHz之間運行。
Due to this slim gap between these frequencies, altimeters, which are “critical equipment for landing a plane in low visibility conditions,” can potentially be affected.
由於這些頻率之間的微小差距，作為「飛機在低能見度條件下著陸的關鍵設備」的高度計可能會受到影響。
critical(adj.)關鍵的;至關重要的visibility(n.)能見度
In fact, since January 2022, more than 100 incidents of suspected 5G interference have been reported in the US.
事實上，自2022年1月以來，美國已傳出100多起疑似5G干擾事件。
As a result, cell carriers in the United States have been limiting 5G use around airports as a precaution.
因此，作為預防措施，美國電信業者一直限制在機場周圍使用5G。
precaution(n.)預防、預防措施=prevention
US airlines have been addressing this issue in several ways.
美國航空公司一直在以各種方式解決這個問題。
address(v.)解決;處理=deal with=handle=tackle
First, they have been retrofitting older aircraft, like the Airbus A320, with newer radio altimeters that are less susceptible to 5G interference.
首先，他們一直在對空中巴士A320等老式飛機進行改裝，配備較新、不易受5G干擾的無線電高度計。
retrofit(v.)使(機器)改型翻新;升級改造retrofit engines with pollution controls對引擎加裝污染控制系統be susceptible to…易受…影響的=be subject to…
Additionally, in June, the US Federal Aviation Administration released a statement requiring regional aircraft operators to install radio frequency filters on planes that are at higher risk from interference.
此外，6月時，美國聯邦航空管理局發布了一項聲明，要求區域飛機運營商在受干擾風險較高的飛機上安裝射頻濾波器。
install(v.)安裝radio frequency filters射頻濾波器
Despite Tom Wheeler, the former chairman of the Federal Communications Commission, stating “that the vast, vast majority of aircraft have altimeters that are shielded from [cellular] signals,” new picocell technology is on the way to address cell phone bans on American flights, which could soon allow US airline passengers the same in-flight data access as those in the EU.
儘管聯邦通信委員會前主席湯姆·惠勒表示，「絕大多數飛機的高度計都屏蔽了（手機）訊號」，但新的微微基站技術正逐漸解決美國航班禁止使用手機的問題，可能很快就會讓美國航空公司的乘客享有與歐盟乘客相同的機上上網服務。
