Millimeter waves — often referred to as mmWaves or high-band 5G — are frequencies starting at 24 GHz and beyond . As radio waves increase in frequency, each wave narrows in length. Because of its high frequencies, mmWave has a limited range of only 300 to 500 feet and struggles to penetrate buildings.
