The advent of in-flight WiFi has revolutionized the way we travel, allowing us to stay connected with the world below even at cruising altitudes. But have you ever wondered how this technology works, and what are the limitations of having WiFi on a plane? In this article, we’ll delve into the world of in-flight connectivity, exploring the history, technology, and future of WiFi on planes.
A Brief History of In-Flight WiFi
The concept of in-flight WiFi has been around for over two decades, but it wasn’t until the early 2000s that the first commercial airlines began offering internet access on select flights. One of the pioneers in this field was Boeing, which launched its Connexion by Boeing service in 2001. This service used a satellite-based system to provide internet access to passengers on select flights.
However, the service was short-lived, and Boeing discontinued it in 2006 due to lack of demand and high operating costs. But the idea of in-flight WiFi didn’t die there. In the late 2000s, a new generation of in-flight WiFi providers emerged, including Gogo, Row 44, and ViaSat. These companies developed new technologies that made in-flight WiFi faster, cheaper, and more accessible to airlines and passengers.
How In-Flight WiFi Works
So, how does in-flight WiFi work? The technology behind it is quite complex, but we’ll break it down in simple terms. There are two main types of in-flight WiFi systems: air-to-ground (ATG) and satellite-based.
ATG systems use a network of cell towers on the ground to provide internet access to planes flying over the continental United States. These systems use a combination of cellular and WiFi technologies to connect planes to the internet. The most well-known ATG provider is Gogo, which offers internet access on many domestic flights in the US.
Satellite-based systems, on the other hand, use a network of satellites in orbit around the Earth to provide internet access to planes. These systems use a combination of satellite and WiFi technologies to connect planes to the internet. Satellite-based systems are more expensive than ATG systems but offer global coverage, making them ideal for international flights.
The Technology Behind Satellite-Based Systems
Satellite-based systems use a combination of geostationary and low-Earth orbit (LEO) satellites to provide internet access to planes. Geostationary satellites are located in a fixed position above the equator and offer broad coverage of the Earth’s surface. LEO satellites, on the other hand, are located in a lower orbit and offer faster data speeds and lower latency.
To connect to the internet, planes use a satellite antenna to communicate with the nearest satellite. The signal is then transmitted to a ground station, which connects to the internet backbone. The data is then transmitted back to the plane, where it’s distributed to passengers through a WiFi network.
