Which one is a key technology for 5G system?

How 5G Works. Like other cellular networks, 5G networks use a system of cell sites that divide their territory into sectors and send encoded data through radio waves . Each cell site must be connected to a network backbone, whether through a wired or wireless backhaul connection.

Massive MIMO is considered to be one of the key technologies of 5G, and it is the only wireless technology that can increase system capacity tenfold and 100 times.

What is 5G signaling? Signaling is the relay of control messages between network functions in a 5G core network . A well designed signaling architecture results in optimum performance with no bottlenecks, balances loads across network functions, and results in high reliability.

A: 5G is based on OFDM (Orthogonal frequency-division multiplexing), a method of modulating a digital signal across several different channels to reduce interference . 5G uses 5G NR air interface alongside OFDM principles. 5G also uses wider bandwidth technologies such as sub-6 GHz and mmWave.
