5G standards divide frequencies into two groups: FR1 (450 MHz – 6 GHz) and FR2 (24 GHz – 52 GHz) . Most early deployments will be in the FR1 space. Research is ongoing into using FR2 frequencies, which are also known as extremely high frequency (EHF) or millimeter wave (mmWave) frequencies.

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.
