Connected Car: Was ist die beste Technologie?

Eine schnelle Internetverbindung ist essentiell für vernetzte Fahrzeuge. Doch, welche Technologie wird sich durchsetzen, 5G oder WiFi?

A battle between WiFi and 5G in the car is now in full swing, reported the Wall Street Journal recently. Toyota and General Motors support a WiFi standard for cars talking to each other and Ford and BMW support 5G.So what’s the difference?  5G is about 10 times faster than current broadband.  An example of that when it comes to cars communicating with each other is that with WiFi, you get a warning alert if a vehicle a couple of cars ahead stops short.  But under 5G, you can SEE the video feed of cars and trucks ahead of you (and by a greater distance ahead).  5G is also faster so the data is more immediate.The problem is that the government has already invested “hundreds of millions of dollars” in a swath of WiFi dedicated for cars called DSRC and GM and Toyota have already made large investments in it.GM and Toyota are asking the Trump administration to support a 2016 plan to mandate DSRC in new cars starting in 2021.  But Ford, BMW and others are lobbying the Trump administration to make 5G the new standard because it offers better capability, said the WSJ.Car makers are now in a “showdown” over which technology should be the future standard for vehicle-to-vehicle (V2V) or vehicle-to-anything (V2X) communications (V2X includes vehicle communication with traffic lights and other roadway infrastructure).
