Imagine if your car could react and communicate its reaction to hundreds of cars around it, all within a millisecond. Not only could we prevent car accidents, we could end traffic jams altogether. Hundreds of self-driving cars that move in concert, with limited risk that they’ll hit each other because they all know exactly where they are in real-time and reacting to the actual world around them.
4G can go ten kilometers and barely lose signal. 5G maxes out at about 300 meters and can’t go through walls or rain.
T-Mobile are claiming to have successfully managed to pull off 5G on the old 4G frequency of 600 MHz, which can serve hundreds of miles in every direction from a single tower. However, reports are mixed about whether or not they’ll be able to achieve the speeds and latency we’ve talked about here.
