How Does the Technology Work?

The technology behind AST SpaceMobile is complex, but the basic concept is relatively straightforward: satellites act as cell towers in space, communicating directly with mobile phones on Earth. Let's break down the key components:

• Satellites: AST SpaceMobile's satellites are the heart of the network. These aren't small, simple satellites; they are large, sophisticated spacecraft equipped with advanced technology. Each satellite features a large phased array antenna, which is essential for transmitting and receiving signals over a broad area. The satellites operate in low Earth orbit (LEO), which reduces latency and improves signal strength compared to geostationary satellites.

• Phased Array Antenna: The phased array antenna is a critical component of AST SpaceMobile's technology. It consists of thousands of individual antennas that work together to transmit and receive signals. By precisely controlling the phase of the signals emitted from each antenna, the phased array can focus the signal in a specific direction, similar to how a spotlight focuses light. This allows AST SpaceMobile to provide strong, reliable connections to mobile phones on the ground.

• Ground Stations: While the satellites communicate directly with mobile phones, ground stations are still necessary for managing the network and routing traffic. Ground stations serve as gateways between the AST SpaceMobile network and the terrestrial internet. They handle tasks such as authentication, billing, and data routing. AST SpaceMobile has established a network of ground stations around the world to support its operations.

• Mobile Phones: One of the most remarkable aspects of AST SpaceMobile's technology is that it works with standard, unmodified mobile phones. This means you don't need to buy a special satellite phone or install any additional hardware to connect to the AST SpaceMobile network. Your existing smartphone can seamlessly switch between terrestrial cellular networks and the AST SpaceMobile network, depending on signal availability.

AST SpaceMobile's network operates using licensed cellular frequencies, which are the same frequencies used by terrestrial mobile networks. This allows mobile phones to seamlessly connect to the AST SpaceMobile network without any modifications. When you're in an area with terrestrial cellular coverage, your phone will connect to the local cell tower as usual. However, when you move outside of cellular coverage, your phone can connect directly to an AST SpaceMobile satellite.

The connection process is automatic and transparent to the user. Your phone constantly scans for available networks, and if an AST SpaceMobile satellite is within range, it will attempt to connect. Once connected, you can use your phone as usual to make calls, send texts, and access the internet. The data is routed through the AST SpaceMobile network to a ground station and then to the terrestrial internet.
