$AST SpaceMobile, Inc.(ASTS)$ $SpaceX(SPCX)$ The space-based direct-to-cell competition seems to be taking two distinct technological routes. Starlink functions more like a basic safety net, while AST SpaceMobile (ASTS) is leveraging premium low-band spectrum, such as the 800 MHz block from Grain, to construct a full-fledged cellular broadband network in orbit.
By combining assets from Grain, AT&T, and Verizon, they're creating a massive, contiguous 7MHz x 7MHz low-band pipeline. This essentially acts as an extra-wide highway, which should help avoid data bottlenecks.
With that capacity, ASTS is reportedly achieving real-world speeds between 98.9 Mbps and 200 Mbps. That's enough to handle smooth 4K video streaming and FaceTime calls even from remote areas with no coverage.
In contrast, Starlink relies on mid-band spectrum, which can have more difficulty penetrating obstacles like trees and walls. Their speeds are typically in the 7–14 Mbps range, which is more suited for text and voice rather than high-bandwidth applications.
By pooling resources from major US carriers, AST SpaceMobile appears to be building a genuine high-speed orbital network.
