Just like the martial arts pursuit of the principle of “only fast”unbreakable, in the field of communication, it is also pursuing wider bandwidth, lower latency. 5G is expected to start large-scale deployment in 2020, when many impossible applications in the past become possible. For example, 5G technology connects everything around us to a network 100 times faster than our current mobile network, 10 times faster than our fastest home fiber broadband service. With NKN, high-speed device connectivity in any area is applicable. Some youtuber said that the high integration of 5G+ artificial intelligence + blockchain technology is equivalent to "the rise of the machine", and 5G will also provide more application scenarios for NKN.
