Amazon's trying to launch a global satellite cellphone network in 2028 亚马逊计划于2028年启动全球卫星蜂窝网络

TL;DR

• Amazon filed an FCC application to deploy a 5,105-satellite Leo constellation for direct-to-device services starting in 2028.
• The service will support voice, messaging, data, and emergency communications via partnerships with mobile operators and Apple.
• Amazon plans to leverage Globalstar’s spectrum and collaborate on future satellite services while expanding beyond its initial 3,200-satellite Leo project.
• In-orbit signal processing is highlighted as a key performance enhancement for the new constellation.

Why It Matters

This move positions Amazon as a major player in low-earth orbit (LEO) connectivity, challenging established players like Starlink and Iridium. For AI practitioners and telecom strategists, it underscores the growing integration of space-based infrastructure with terrestrial networks—critical for enabling global IoT coverage, disaster response systems, and seamless device-to-satellite communication. The emphasis on in-orbit processing also hints at edge-AI applications within satellite payloads, potentially reducing latency and bandwidth costs.

Technical Details

• Constellation Scale: 5,105 satellites, nearly double Amazon’s original Leo plan (~3,200), with over 375 launched by July 2nd.
• Spectrum Utilization: Will use Globalstar’s allocated spectrum; additionally requests use of Iridium-assigned spectrum outside U.S., despite Rocket Lab’s ongoing acquisition of Iridium.
• Service Model: Direct-to-device capability similar to Starlink-T-Mobile partnership, targeting consumer devices without requiring ground stations.
• In-Orbit Processing: Satellites will process signals before relaying them to improve efficiency and reduce downlink load—a potential enabler for onboard AI inference or routing optimization.
• Use Cases: Consumer broadband, emergency messaging, disaster recovery, and collaboration with Apple for future device-integrated satellite features.

Industry Insight

Amazon’s aggressive expansion into LEO satellite services signals a shift toward integrated space-terrestrial ecosystems where AI-driven network management becomes essential. Operators should prepare for increased competition in direct-to-device markets, particularly as regulatory approvals unfold. Additionally, the strategic overlap with Apple and Globalstar suggests that future satellite-AI convergence may prioritize proprietary hardware-software stacks, pushing third-party developers to adapt their solutions for constrained orbital environments.

TL;DR

• Amazon proposes a 5,105-satellite Leo constellation for direct-to-device services (voice, messaging, data, emergency) starting in 2028.
• The new network will leverage Globalstar’s spectrum and collaborate with Apple, building on its existing acquisition of Globalstar’s satellite assets.
• It will complement Amazon’s broader Leo broadband platform and include in-orbit signal processing to enhance performance.
• The FCC application also requests use of Iridium’s spectrum outside the U.S., amid Rocket Lab’s ongoing acquisition of Iridium.
• Over 375 satellites from Amazon’s initial ~3,200-satellite Leo plan have launched as of July 2nd.

为什么值得看

Amazon此举标志着科技巨头深度整合卫星通信与移动网络，直接挑战SpaceX在低轨卫星领域的垄断地位。其“直连设备”模式若成功，将重塑全球偏远地区通信架构，并为苹果、运营商等生态伙伴提供关键基础设施支持。

技术解析

• 新星座规模达5,105颗卫星，约为初始Leo计划（约3,200颗）的1.6倍，显示亚马逊对低轨卫星网络的长期投入决心。
• 采用“星上信号处理”技术，即在轨道端完成信号预处理后再回传地面，可显著降低延迟并提升链路效率。
• 频谱资源复用：计划使用Globalstar现有频段，并申请扩展至Iridium在美境外频段，体现对稀缺频谱资源的战略争夺。
• 服务定位明确：不仅面向消费者宽带，更强调应急通信与灾害响应能力，符合政府与公共安全需求导向。
• 部署节奏清晰：2028年启动部署，配合已发射超375颗卫星的进度，显示其具备规模化组网与持续迭代能力。

行业启示

• 卫星互联网正从“宽带接入”向“终端直连”演进，未来手机、IoT设备将原生支持卫星通信，推动硬件架构重构。
• 科技巨头（如亚马逊、苹果、微软）将通过并购+自建+合作三重路径构建自主可控的太空通信底座，加剧产业链垂直整合。
• 频谱协调与国际监管将成为竞争焦点，尤其在跨域频段使用与跨国部署方面，需高度依赖FCC及国际电信联盟审批机制。
