How Does In-Flight Wi-Fi Work?
So, how does in-flight Wi-Fi work? The technology behind it is quite fascinating. There are two main types of in-flight Wi-Fi systems: air-to-ground (ATG) and satellite-based.
Air-to-Ground (ATG) Systems
ATG systems use a network of cellular towers on the ground to provide internet connectivity to aircraft. As the plane flies over a cellular tower, it establishes a connection, allowing passengers to access the internet. The signal is then transmitted to the aircraft via a small antenna, which is usually installed on the plane’s fuselage.
ATG systems are commonly used in the United States and offer relatively fast internet speeds, with some airlines offering speeds of up to 10 Mbps. However, the coverage area is limited to the continental United States, and the signal can be disrupted by mountains and other terrain features.
Satellite-Based Systems
Satellite-based systems, on the other hand, use a network of satellites orbiting the Earth to provide internet connectivity. These systems are more complex and expensive than ATG systems but offer global coverage, making them ideal for international flights.
Satellite-based systems use a small antenna installed on the plane’s fuselage to communicate with the satellite, which then transmits the signal to a ground station. The signal is then routed to the internet, allowing passengers to access online content.
