5G

"5G represents the fifth generation of cellular technology, and is the successor to 4G/LTE.

5G takes advantage of many chunks of spectrum ranging from long-range UHF frequencies up through short-range extremely high millimeter-wave frequencies (mm Wave)

When broadcast over long-range frequencies, 5G may only have a modest speed improvement over 4G/LTE. In core urban and suburban areas that are frequently overloaded in the 4G/LTE spectrum the extra capacity that 5G brings to cellular allows for dramatic overall improvements.

NOTE: 5G cellular and 5Ghz Wi-Fi are entirely different things."
