A, 5 g spectrum


Increase the bandwidth is the most direct method to increase capacity and transmission rate, is now the biggest bandwidth will reach 400 MHZ 5 g, given the current frequency usage, 5 g will have to use high frequency communication,


3 GPP protocol defines from Sub6G (FR1) to 5 G of millimeter wave (FR2) target spectrum, including FR1 is the core of the 5 G band, with 3.5 G (C band) near the spectrum as gold band of 5 G deployment, FR2 because of high frequency spectrum, the attenuation fast, as an aid in the spectrum of 5 G, used for hot spots rate increase,


3 GPP protocol defined 5 g spectrum FR1 as follows, compared with the 4 g LTE band to do some of the merger, split and to add, including SUL TDD (auxiliary) used for has decoupled in order to enhance upward edge cover


2, 5 g frequency calculation


3 GPP protocol defines from Sub6G (FR1) to 5 G of millimeter wave (FR2) target spectrum, including FR1 is the core of the 5 G band, with 3.5 G (C band) near the spectrum as gold band of 5 G deployment, FR2 because of high frequency spectrum, the attenuation fast, as an aid in the spectrum of 5 G, used for hot spots rate increase, 3 GPP defines the Global raster (Global grid frequency point, use Δ FGlobal said), the higher the frequency, the greater the grid, 5 G is used to calculate the dot, no longer need to use like LTE band the starting frequency corresponding to the number and the point of the look-up table to calculate,
