The UMTS frequency bands are radio frequencies used by third generation (3G) wireless Universal Mobile Telecommunications System networks. They were allocated by delegates to the World Administrative Radio Conference (WARC-92) held in Málaga-Torremolinos, Spain between 3 February 1992 and 3 March 1992. [1]
UMTS頻段 (英語: UMTS frequency bands )是 通用移動通訊系統 (英語: UMTS, Universal Mobile Telecommunications System )所使用的無線頻率範圍。 UMTS頻段最早是在 國際電信聯盟 的 世界無線電行政大會 (英語:World_Administrative_Radio_Conference) 在1992年的會議(WARC-92)中分配的 [1] 。 在212號決議中,為未來公眾陸地行動電信系統(FPLMTS),即 IMT-2000 的前身分配了頻段 [2] 。

Some carriers such as T-Mobile use band numbers to identify the UMTS frequencies. For example, Band I (2100 MHz), Band IV (1700/2100 MHz), and Band V (850 MHz).

2021年6月28日 · UMTS employs various frequency ranges within the 850 MHz, 900 MHz, 1700 MHz and 2100 MHz bands for different geographical regions. Generally, with FDD, the frequency band for Europe and Africa is 2110-2170 MHz in the downlink and 1920-1980 MHz in the uplink.
UMTS is offering greater spectral efficiency than GSM TM and has 2 modes: an FDD mode (Frequency Division Duplex) where uplink (user equipment UE => UTRA network = UTRAN) and downlink (UTRAN => UE) communication are separated in the frequency
