美联邦通信委员会(FCC)将投票放宽卫星功率规则,助力SpaceX的星链计划。
FCC Set To Vote on Easing Satellite Power Rules, Boosting SpaceX's Starlink

美国联邦通信委员会(FCC)计划于4月30日投票决定关于卫星频谱共享的新规,此举普遍预计将使SpaceX的星链网络受益。拟议的变更将允许像星链这样的低地球轨道(LEO)运营商以更高的功率水平进行传输,可能为农村地区提供更快、更可靠的宽带服务。 目前,上世纪90年代制定的法规优先考虑地球静止轨道(GSO)卫星系统。FCC认为,这些规则现在阻碍了创新,并限制了许多美国人获得更快的互联网接入。SpaceX认为,现有的功率限制基于过时的技术,并且不公平地偏袒较老的卫星系统。 然而,像Viasat和DIRECTV这样的GSO运营商反对这一变化,担心会对他们的网络造成干扰。他们质疑SpaceX的干扰研究。尽管存在这些担忧,FCC认为现代技术可以减轻干扰风险,并且放宽限制将刺激竞争并扩大宽带接入。这项投票代表了卫星频谱政策的重大转变,可能重塑数百万人的互联网连接。

The Federal Communications Commission (FCC) announced Wednesday it will vote on an order to revamp satellite spectrum-sharing rules that would benefit low-Earth orbit broadband providers - and SpaceX stands to gain the most.

“By discarding last century’s satellite regulations, we could see billions of dollars in benefits for the American economy and broadband speeds many times faster than what is available today,” FCC Chairman Brendan Carr said in a statement.

“This overdue rethinking of space spectrum sharing rules will bring greater competition to the broadband marketplace and reduce the number of satellites needed to serve a given area.”

The vote on April 30 could reshape how tens of millions of Americans, particularly those in rural communities, connect to the internet from space.

The proposed order would raise the power levels that low-earth orbit (LEO) operators are permitted to use in frequency bands shared with incumbent geostationary orbit systems. For SpaceX, whose Starlink network already spans more than 10,000 satellites, the change would mean substantially faster and more reliable service.

Not everyone is on board. Geostationary operators, including Viasat, SES, and DIRECTV, have opposed the move, arguing that allowing Starlink to transmit at higher power would cause damaging interference to their own networks.

In a filing submitted Tuesday, DIRECTV told the agency that SpaceX’s interference studies contain “significant unresolved questions.”

SpaceX has dismissed those concerns as a defense of the status quo. 

“The question of whether the [equivalent power flux density] framework harms consumers by unnecessarily constraining [LEO] services has been definitively resolved: it does,” SpaceX wrote last month. The company added that the current rules unfairly favor what it called outdated satellite systems while leaving rural users underserved.

The FCC appeared to agree. The agency said in its release that “government-imposed overprotection of GSO systems has meant that American households and businesses—most critically in rural and remote areas—do not receive the fastest space-based broadband American innovation has available.”

The international power limits at the center of the dispute were established in the 1990s and were designed to shield geostationary satellites from interference caused by lower-orbiting constellations. At the time, LEO broadband networks like Starlink did not yet exist.

The FCC took an early step toward reform in January, when it approved 7,500 additional second-generation Starlink satellites and granted SpaceX a temporary waiver from the power restrictions while the agency’s broader rulemaking proceeded.

SpaceX has argued that the existing Equivalent Power Flux Density (EPFD) limits rely on obsolete computer models that fail to account for modern beamforming and interference-mitigation technologies now standard in newer satellite systems.

As of March, Starlink’s constellation comprised more than 10,020 satellites in low Earth orbit, accounting for roughly 65 percent of all active satellites worldwide, with more than 10 million subscribers reported as of February.

A formal vote on the new power rules would mark the most consequential shift in satellite spectrum policy in a generation.
