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.
Read moreWhy is it called millimeter wave?
They are called millimeter waves because they vary in length from 1 to 10 mm , compared to the radio waves that serve today’s smartphones, which measure tens of centimeters in length. Until now, only operators of satellites and radar systems used millimeter waves for real-world applications.
Read moreAre mm waves safe?
In humans, MM-waves have penetrating effects including impacts on the brain, producing EEG changes and other neurological/neuropsychiatric changes, increases in apparent electromagnetic hypersensitivity and produce changes on ulcers and cardiac activity .
Read moreWhat is the meaning of millimeter wave?
Millimeter waves are electromagnetic (radio) waves typically defined to lie within the frequency range of 30–300 GHz . The microwave band is just below the millimeter-wave band and is typically defined to cover the 3–30-GHz range.
