IMT-2000 (International Mobile Telecommunications-2000) is the global standard for third generation (3G) wireless communications as defined by theInternational Telecommunication Union.[1][2][3]
In 1999 ITU approved five radio interfaces for IMT-2000 as a part of the ITU-R M.1457 Recommendation.[4] The five standards are:[5]
To meet the IMT-2000 standards, a system must provide peak data rates of at 384 kbit/s for mobile stations and 2 Mbit/s for fixed stations.[2][6][7][8][9]

With minimum consistent Internet speeds of 144 Kbps, 3G was supposed to bring 'mobile broadband.'
