The Low Earth Orbit Communication Race is on - Simon Allard, Head of Network Architecture and Delivery at 2degrees (NZ)

Simon Allard from 2° breaks down the massive technological shift coming to New Zealand mobile connectivity through the partnership with AST SpaceMobile. The episode explores why 2° chose AST over SpaceX, focusing on the ability to provide voice, data, and SMS services to standard 4G handsets from day one. Simon Allard highlights how this approach differentiates 2° in the current New Zealand space race, emphasizing the strategic importance of end-to-end network control.A central theme of the discussion is the physical and technical scale of the AST SpaceMobile constellation. Simon Allard explains that the SpaceMob model uses fewer but much larger satellites, known as BlueBirds, which measure over 200 square meters. These massive arrays function as cell towers in space, utilizing advanced beamforming technology to maintain stationary coverage cells on the ground even as the satellites orbit at high speeds. This ensures that the 48-kilometer hexagonal cells remain consistent for users on the ground.The conversation also dives into the logistical challenges of building the necessary ground infrastructure. Simon Allard recounts the process of selecting Marton in the middle of the North Island for the gateway station. The site required a 10-degree line of sight, 500 kilowatts of power, and access to diverse fiber routes. Interestingly, Marton was chosen partly because regulatory bodies did not expect the area to receive 6G, freeing up the QV band frequencies needed for satellite backhaul.Disaster resilience is a major focus, particularly in light of Cyclone Gabrielle. Simon Allard details how the SpaceMobile network acts as a safety net, allowing users to make 111 emergency calls and send texts even when land-based towers are destroyed. The episode explains how the 2° core network can prioritize emergency traffic and manage spectrum to ensure connectivity remains available during natural disasters, providing a critical lifeline for search and rescue operations.Finally, the episode looks ahead to the future of the SpaceMob partnership, including the potential for high-density IoT connectivity and maritime services. By leveraging the 900 megahertz spectrum, 2° aims to offer a seamless experience where users can transition from terrestrial towers to satellite coverage without dropping a call. Simon Allard concludes with insights into the testing phase and the upcoming launch of products that will redefine the boundaries of the mobile network in New Zealand.
