由于频谱、基础设施和互操作性挑战,直接对设备卫星宽带面临延误,将全面部署推至2036年左右。 Direct-to-device satellite broadband faces delays due to spectrum, infrastructure, and interoperability challenges, pushing full deployment to around 2036.

在2026年SmallSat专题讨论会上,业界领导人警告说,尽管取得了技术进步,但直接到设备的卫星宽带仍面临重大障碍,例如频谱限制、天线效率低下、监管障碍和市场规模不确定。 At the 2026 SmallSat Symposium, industry leaders warned that direct-to-device satellite broadband faces major hurdles despite technical progress, citing spectrum limits, antenna inefficiencies, regulatory barriers, and uncertain market size. 地面基础设施落后于卫星部署,造成延误和系统性风险,而软件界定的网络和卫星间继电器则提供替代办法,但对传统模式构成威胁。 Ground infrastructure lags behind satellite deployment, creating delays and systemic risks, while software-defined networks and inter-satellite relays offer alternatives but threaten traditional models. 大型卫星和机载处理越来越有必要,但专有系统和缺乏互操作性阻碍了在建立统一的空间互联网方面的进展,而充分实现该目标仍有可能在十年之后。 Larger satellites and onboard processing are becoming necessary, but proprietary systems and lack of interoperability hinder progress toward a unified space internet, with full realization still likely a decade away.
