T-Mobile's CFO expressed skepticism about Starlink Mobile's viability during a recent conference, arguing that the signal's strength and speed are insufficient to penetrate Earth's atmosphere. The comments come as part of broader discussions about the future of satellite-based internet services. The CFO highlighted technical limitations, suggesting that the signal's performance is hindered by atmospheric conditions. This critique underscores the challenges faced by satellite internet providers in delivering reliable connectivity. Starlink Mobile, part of Elon Musk's broader space ambitions, aims to offer mobile broadband through satellite networks. However, T-Mobile's concerns suggest that the technology may not yet be mature enough to compete with traditional cellular networks.
