IMT-2000, International Mobile Technology-2000, is the thirdgeneration
technology standard developed by the International
Telecommunications Union (ITU) for global mobile communications.
The spectrum allocation for IMT-2000 is 1885-1980 MHz for uplink
(mobile to base station) communication and 2110-2170 MHz for
downlink (base station to mobile) communication.
In Europe, the system is known as UMTS. The spectrum
allocation is 1920-1980 MHz (uplink) and 2110-2170 MHz
(downlink) for Frequency-Division Duplex (FDD) and
1900-1920 MHz and 2010-2025 MHz for Time Division
