TD 3700

Commonly referred to as the "TD 3700" band, the n77 band operates in the 3700 MHz frequency range for 5G NR networks. It is a wider band than the popular n78 band, covering from 3300 to 4200 MHz, providing more flexibility and capacity for operators to deliver high-speed connectivity. As a TDD (Time Division Duplexing) band, it shares the same frequency for transmitting and receiving, with timing control separating the two functions.
