Not All 5G Is Equal: mmWave, Low-Band, and Mid-Band Explained

Marko Aliaksandr/ShutterstockYou’ve probably heard that 5G uses the mmWave (millimeter wave) spectrum to reach its 10 Gbps speeds. But it also uses the low- and mid-band spectrums, just like 4G. Without all three spectrums, 5G wouldn’t be reliable. So, what’s the difference between these spectrums? Why do they transfer data at different speeds, and why are they all critical to 5G’s success? How Do Electromagnetic Frequencies Transfer Data? Before we get too deep into low-band, mid-band, and mmWave, we need to understand how wireless data transmission works. Otherwise, we’ll have trouble wrapping our heads around the differences between these three spectrums. Radio waves and microwaves are invisible to the naked eye, but they look and behave like waves in a pool of water. As a wave’s frequency increases, the distance between each wave (the wavelength) gets shorter. Your phone measures wavelength to identify frequencies and to “hear” the data that a frequency is trying to transmit. WikipediaBut a stable, unchanging frequency can’t “talk” to your phone. It needs to be modulated by subtly increasing and decreasing the frequency rate…. Click below to read the full story from How To Geek
