Why is WiFi not available on all planes?
WiFi is not available on all planes due to various technical and logistical reasons. One of the primary reasons is the lack of infrastructure to support in-flight internet connectivity. Many airlines have not invested in the necessary equipment and technology to provide WiFi on their flights. Additionally, some planes may not be equipped with the required antennas and routers to establish a stable internet connection.
Another reason is the cost associated with providing in-flight WiFi. Airlines need to pay for the satellite or air-to-ground connectivity, which can be expensive. They also need to consider the cost of installing and maintaining the necessary equipment on their planes. As a result, many airlines have chosen not to offer WiFi on their flights, especially on shorter routes or older planes.
How does in-flight WiFi work?
In-flight WiFi works by using a combination of satellite and air-to-ground technology to establish a connection between the plane and the internet. When a plane is equipped with WiFi, it uses an antenna to connect to a satellite or a network of cell towers on the ground. The signal is then transmitted to a router on the plane, which distributes the internet connection to passengers’ devices.
The technology used for in-flight WiFi is similar to the technology used for mobile phone networks. However, the signal strength and quality can be affected by the plane’s altitude, speed, and location. To overcome these challenges, airlines use specialized equipment and technology, such as satellite antennas and amplifiers, to boost the signal and provide a stable internet connection.
