衛星覆蓋層服務
AT&T 推出 AST SpaceMobile BlueBird 服務
AT&T 正籌備一項衛星支援服務，透過與 AST SpaceMobile 合作，將行動網絡覆蓋範圍，延伸至其地面網絡以外的地區。此服務設計旨在讓標準智能手機，透過 AT&T 持牌頻譜，直接連接至低地球軌道的 BlueBird 衛星，並由地面閘道站，將衛星流量連接至這家電訊商的行動核心網絡。
AST SpaceMobile 提供太空平台及閘道技術，而 AT&T 則根據一份延續至 2030 年的商業協議，提供頻譜、網絡整合、帳單及分銷服務。此服務預計將支援語音、短訊及行動數據，未來或有望加入影片功能。AST SpaceMobile 表示，其設計目標為每波束最高 40 MHz 頻寬，峰值速度達 120 Mbps。
對消費者而言，此服務有望擴大緊急、偏遠地區及海上使用場景的連接能力。此合作亦反映出更廣泛的趨勢：衛星網絡正逐步成為地面行動網絡覆蓋的補充，而非取代。
英文原文
AT&T is preparing a satellite-backed service that will extend mobile connectivity beyond its terrestrial footprint through a partnership with AST SpaceMobile. The offering is designed to let standard smartphones connect directly to Low Earth orbit BlueBird satellites using AT&T’s licensed spectrum, with terrestrial gateways linking satellite traffic to the carrier’s mobile core.
AST SpaceMobile provides the space-based platform and gateway technology, while AT&T supplies spectrum, network integration, billing and distribution under a commercial agreement running through 2030. The service is expected to support voice, text and mobile data, with video as a possible future capability. AST SpaceMobile has cited design targets of up to 40 MHz per beam and peak speeds of 120 Mbps.
For consumers, the service could expand connectivity for emergency, remote and maritime use cases. The partnership reflects a broader shift toward satellite networks complementing terrestrial mobile coverage rather than replacing it.
