UMTS Band 39, also known as TD 1900 MHz, is a frequency band used for third-generation (3G) wireless Universal Mobile Telecommunications System (UMTS) networks. This band operates within the frequency range of 1880 to 1920 MHz and is allocated for Time Division Duplex (TDD) technology. The band is intended for use in various regions around the world, including Asia and Europe, and is often used in data-centric applications due to its unpaired spectrum, where the uplink and downlink share the same frequency but are time-separated.
