5G is different from 4G and 3G in several ways, but among the notable differences is the wide range of frequencies supporting 5G: low band, mid band and high band millimeter wave. No other mobile generation has had that wide spread of frequencies supporting the networks.
Also notable for 5G networks is aggregation of licensed and unlicensed spectrum.
To be sure, 4G used carrier aggregation to allow mobile operators to combine blocks of spectrum, including contiguous frequencies within a band, non-contiguous frequencies within the same band, or non-contiguous spectrum in different bands.
Carrier aggregation remains important in 5G as a method of increasing end user bandwidth.
