SpaceX President Gwynne Shotwell says the company aims to build out ground-based infrastructure to complement its satellite network for "a true mobile service" (Reuters)
↗
SpaceX plans to add terrestrial network elements to work alongside its satellite constellation to deliver a fully mobile service.
Engineers will need to design systems that can switch between satellite and ground links, affecting routing, latency handling, and device firmware. The hybrid approach could reduce reliance on satellite-only coverage, but also introduces new integration points and operational costs for building and maintaining ground stations.

A ground component will be added to the existing satellite network, creating a hybrid architecture for mobile connectivity.
Implementing the hybrid model will require investment in terrestrial infrastructure and software to manage handoffs between satellite and ground links.
Service will still depend on satellite coverage in areas lacking ground stations, so the new system will not replace the satellite layer entirely.
THE READ
What elseif makes of it.
SpaceX’s announcement signals a shift from a purely space-based communications model to a combined satellite-and-ground network. The company’s leadership indicated that this addition is intended to enable a "true mobile service," implying that devices will be able to maintain connectivity through either medium. For engineers, this means rethinking network topology to accommodate dual paths and ensuring seamless transition between them. The immediate engineering impact is the need to develop or adopt protocols that can detect the optimal link and switch traffic without disrupting active sessions. Existing satellite-only stacks will have to be extended with ground-station discovery, authentication, and handover logic. This adds software complexity and may require firmware updates for customer devices that currently only speak to the satellite layer. From an operational standpoint, constructing ground infrastructure entails capital outlay for site acquisition, antenna deployment, and backhaul connectivity. Engineers responsible for rollout will need to plan for site power, cooling, and integration with existing network management tools. The cost model will therefore expand beyond la
