Semiconductors must be used to make chips, and 5G hardware is composed of different chips. The construction of 5g system requires a large number of chip hardware, semiconductors as the material of the chip, play an important role in it, making crystals must use semiconductors, and the communication hardware of 5G technology is a semiconductor chip composed of different kinds of chips.
Not really. 5G is a technological change, from hardware to software, and even specific network protocols may change. Semiconductors are used to make chips, and chips are the basis.
Not really. A semiconductor is a material with moderate electrical conductivity.
5G can be understood as Internet speed
