AST SpaceMobile (ASTS) shares declined 10.53% to $36.65, losing $4.32 during the trading session. The decline came as the company reported a major technical milestone involving AT&T and its satellite connectivity network. The successful handoff between terrestrial cellular infrastructure and satellite coverage marks progress toward integrated mobile services.
AST SpaceMobile and AT&T completed a successful connection transfer between their respective wireless networks. The milestone also involved telecommunications technology providers Ericsson and Nokia, which supported the network integration. According to the companies, the demonstration represents the industry’s first successful handoff between terrestrial cellular coverage and direct-to-device satellite connectivity.
The test took place outside Granite Falls, Washington, on October 21, 2026, at 8:15 a.m. Pacific Time. During the demonstration, the participating networks transferred an active connection without requiring users to manage the transition. Consequently, the achievement addresses a technical challenge associated with maintaining mobile connectivity across different network environments.
Previously, AST SpaceMobile demonstrated voice calls, text messaging and video calls through its BlueBird satellites. Those tests established the network’s ability to connect ordinary smartphones directly with satellite infrastructure. However, the latest demonstration focused on maintaining service while devices moved between terrestrial and satellite coverage.
The latest achievement involved different responsibilities across the participating telecommunications companies. AT&T supplied its terrestrial wireless infrastructure, while AST SpaceMobile provided its satellite network. Meanwhile, Ericsson and Nokia contributed radio access, core network technology and mobility software to support the connection transfer.
Ericsson supplied AT&T with combined radio and core technology alongside intelligent network automation. This technology helps coordinate transitions between terrestrial infrastructure and satellite coverage. Additionally, the system reduces handoff times from seconds to milliseconds, supporting service continuity for customers and emergency personnel.
Nokia provided radio access technology and mobility software for AST SpaceMobile’s space-based network. Its systems support seamless handovers and help maintain connections as devices move between coverage areas. Together, these technologies establish an important foundation for integrating satellite connectivity into existing mobile networks.
The companies identified beta testing under real-world conditions as the next stage of development. These trials should allow the partners to evaluate network performance and refine the handoff process. Furthermore, the broader objective involves progressing toward commercial services through continued technical development.
AT&T Senior Vice President of Network Robert Walters identified the successful handoff as a significant development. He also outlined the expected transition toward beta services and eventual commercial deployment. However, the companies must complete further testing before introducing the service commercially.
AST SpaceMobile Chief Commercial Officer Wayne Thorsen highlighted the role of BlueBird satellites in expanding mobile broadband coverage. The company designed its satellite network to support everyday smartphones without requiring specialized devices. Moreover, the system aims to extend connectivity into remote locations while providing additional communication support for first responders.
The partnership therefore represents progress toward combining satellite and terrestrial networks into one mobile experience. For AST SpaceMobile, the milestone advances its efforts to expand coverage through its existing satellite infrastructure. Nevertheless, the immediate development focus remains on beta testing, network integration and preparations for commercial deployment.
