It’s easy to get bored on long train journeys and even longer flights. Mobile Wi-Fi now makes it possible to answer emails or read online messages while on the move. But how exactly does this technology work? And is it possible to use your 22Bet login?
Long train journeys and even longer flights can sometimes be quite boring. It would be easy to answer emails, stream series, or make your next vacation plans online while on the move. For a long time, flight mode put a spanner in the works, as did the constantly interrupted network when the train whizzes through remote villages. Deutsche Bahn ICE trains and some airlines now offer mobile WLAN.
How does WLAN work on the train?
Where there was radio silence for a long time, Deutsche Bahn says it now uses all the mobile networks available on the respective railroad line in parallel and feeds its network for the WLAN systems in the trains. Tunnels in particular, where there is not yet sufficient wireless coverage, can pose a problem. While the company provides all passengers with free Internet access, it throttles the data volume in second class after 200 MB per day has been used and asks all passengers to avoid streaming long videos. This is the only way all customers can benefit from the Internet.
WIFI IN THE AIRPLANE IS POSSIBLE WITH THIS TECHNOLOGY
Using the Internet and streaming a film at an altitude of several thousand meters is a technical feat. But how does the signal reach the cabin and the required server? Wi-Fi on airplanes works similarly; only the user is different. Airline flights no longer have to last countless hours to be able to surf. As soon as the descent and ascent are complete and the required altitude has been reached, the Internet is available to passengers on board the airline. But how is it possible to maintain an upright connection on a long-haul flight at this distance from Earth?
Two systems ensure a constant Internet connection during a flight. A primary system uses the network of the respective ground station. Its signals are picked up by receivers on the fuselage of the aircraft, transforming the plane into an airborne hotspot. Passengers can connect to it on both long-haul and shorter flights. The router sends individual data back to the ground station and data is exchanged continuously as long as connectivity is maintained. During a flight, the aircraft switches from one ground station to the next, and smartphones automatically lock in the new signal.
Several WLAN antennas are distributed on board an aircraft, which receive all signals from the mobile passenger devices. These are forwarded to the aircraft’s server, after which external antennas transmit the signal to geostationary satellites. This enables complete network coverage, which is extended by satellite access stations on the ground via a “Meet Me Point.”
DOES WIFI INTERFERE WITH FLIGHT TECHNOLOGY?
On the route between two airports, airlines use all kinds of highly sensitive technologies, some of which are monitored by the ground station via the Internet. When passengers can surf in the air depends on the technology installed in the aircraft. Depending on the approval of the aviation authorities, some systems allow the use of Wi-Fi during take-off and landing. This unrestricted Wi-Fi connection is possible at every stage of the route, as the radio waves do not interfere with any of the electronics on board, even during critical flight phases.
Other airline systems can only be used from an altitude of around 3,000 meters. The connection is most stable when the sky is clear. In this weather situation, there are no interfering elements such as dust or water particles between the satellite and the aircraft that could affect the signal strength.
WHAT ADVANTAGES DOES THE INTERNET OFFER ON BOARD?
Almost all major airlines, such as Lufthansa, are currently working on equipping flights with online capability. In the future, WLAN services will be standard. Offering numerous advantages for city tourists and business flyers who want to stay connected during a short flight from Munich to Hamburg and simply continue their personal surfing routine online. Aircraft technology also benefits from the airlines’ Internet plans. The new “Blackbox in the Cloud” system transmits flight data live to the Internet. In the event of turbulence or flight accidents, all data can be fully evaluated in the future without having to resort to the black box.
For passengers on long-haul routes and holidaymakers, the new technology will change the entire entertainment concept. With appropriate connections for high-resolution end devices, passengers will be able to access the airline’s entertainment program directly via their own mobile devices using Wi-Fi. Travelers only need the airline’s app to access the Internet and stream entertainment content during the flight.
