I’m currently on a high speed train between France and Switzerland and wondering how my cell phone is able to keep up with my very rapidly changing position and generally keep data connectivity?
In: Technology
Mobile cells are quite large in rural areas. Up to 70km diameter. So even if you travel at 300km/h in the TGV you’re still inside the same cell for many minutes, and sending data packages happens in a matter of seconds. The “logging into” a new cell happens in the background while you’re still in the old cell because the areas overlap slightly. These all happens fast enough that you don’t notice unless you’re moving at rocket-speed
