A simple presentation & video looking at how mobile cellular connectivity and wi-fi works in a plane. Also looks at latency & ping calculations on the plane. Finally we will look at how the new European Aviation Network will help improve the data speeds and latency.

7. 7. Calculating the latency and ping timing ©3G4G Latency is defined as the time it takes for a source to send a packet of data to a receiver. In simple terms, half of Ping time
8. 8. Calculating the latency and ping timing ©3G4G • Speed of light = 3 x 108 m/s or 3 x 105 km/s • RF signals travel the same speed as light • Ground station to satellite = 35786 km / 3 x 105 km/s = 120 ms • Satellite to plane approx. 120ms • Ground station to server approx. 10ms • Plane to WiFi approx 50ms (processing delays) • Total latency approx. = 300ms • Ping time, at least 600 ms approx.
