B13 (700 MHz)

FDDFDD: A communication technology that uses separate frequency bands for transmitting and receiving operations. This technique enables simultaneous bi-directional communication by allocating one frequency band for upstream (transmission from the user equipment to the base station) and another distinct… B13 (700 MHz), also known as the US 700 Upper C band, refers to a specific frequency band used for mobile communication. This band, operating in the upper portion of the 700 MHz frequency range, is particularly useful due to its excellent propagation characteristics, allowing signals to travel further and penetrate buildings more effectively compared to higher frequency bands. The designation "FDD" stands for Frequency Division Duplex, a technology that enables simultaneous transmission and reception of signals on two different frequencies. The B13 band is primarily used in the United States.
