On October 5, 2026, Canadian telecommunications provider TELUS and space-based cellular operator AST SpaceMobile announced the successful completion of their initial end-to-end network integration test.
Executed directly between TELUS’ terrestrial wireless core infrastructure and AST SpaceMobile’s low Earth orbit (LEO) satellite constellation, the milestone validates direct satellite-to-cellular connectivity across standard, unmodified consumer smartphones operating on the TELUS network.
Strategic Context and MNO Commercial Ecosystem
The successful integration test builds upon a definitive commercial agreement signed between TELUS and AST SpaceMobile, under which TELUS joined AST SpaceMobile as a strategic equity investor alongside global telecommunications leaders including AT&T, Verizon, Vodafone, Rakuten, and Bell Canada.
The joint initiative aims to eliminate mobile coverage gaps across Canada’s vast and topographically complex terrain, where constructing and maintaining traditional terrestrial cell towers is logistically or economically unfeasible. By connecting standard LTE and 5G smartphones directly to low Earth orbit satellites, TELUS plans to extend mobile connectivity along remote highway corridors, national parks, northern wilderness areas, and offshore zones without requiring consumers or enterprise clients to purchase specialized satellite phones, external antenna attachments, or custom software applications.
Payload Specifications and Non-Terrestrial Architecture
AST SpaceMobile’s constellation architecture utilizes space-based cellular broadband payloads designed in compliance with 3GPP Non-Terrestrial Network (NTN) standards. The system relies on the operator’s custom AST5000 application-specific integrated circuit (ASIC), which provides up to 10,000 MHz (10 GHz) of processing bandwidth per spacecraft.
The proprietary silicon handles real-time radio frequency (RF) digital beamforming, Doppler shift compensation, and dynamic spectrum allocation across large-format phased-array antennas. Operating via mobile network operator (MNO) partner terrestrial spectrum—including low-band 850 MHz and mid-band cellular frequencies—the satellites project steerable spot beams to generate high-power links capable of delivering peak transmission speeds up to 120 Mbps per coverage cell. This link margin enables cellular reception outdoors and through moderate structural obstacles (“one wall in”) directly to standard 3GPP-compliant mobile devices.
Executive Perspective
“Expanding access to emergency services and providing seamless connectivity across Canada’s most remote regions is a core priority for our network strategy,” said Darren Entwistle, President and Chief Executive Officer of TELUS. “Partnering with AST SpaceMobile enables us to leverage space-based cellular broadband to keep Canadians connected, safe, and supported wherever they live, work, or travel, using the everyday smartphones they already own.”
“This successful integration test with TELUS represents another major milestone in bringing space-based broadband to North America,” added Abel Avellan, Founder, Chairman, and Chief Executive Officer of AST SpaceMobile. “Together, we are demonstrating how our space network seamlessly integrates with terrestrial mobile networks to deliver reliable connectivity to unmodified cell phones in areas where cell towers cannot reach.”
Public Safety Integration and Commercial Service Roadmap
Following the network integration test, TELUS and AST SpaceMobile are advancing the platform toward commercial service rollout, targeting customer availability within the next 12 months. Initial commercial services will focus on text messaging, voice calls, and emergency 9-1-1 routing in unserved regional zones, followed by full cellular broadband data and video streaming capabilities.
Beyond consumer mobile services, the network will support public safety communications and enterprise operational logistics across energy, forestry, mining, and construction projects in northern Canada. As AST SpaceMobile expands its Block 2 BlueBird satellite deployment cadence, the integrated space and terrestrial infrastructure will provide continuous direct-to-device cellular coverage across North America.
