IMT stands for International Mobile Telephony. IMT is used to indicate spectrum that is reserved for mobile network operators. The table below lists spectrum assignments by country and operator. The assignments are in MHz and the format 2×10, 2×15, etc means that the spectrum has been assigned on a paired basis with an uplink band and a downlink band also known as FDD or Frequency Division Duplex. The alternative to this is TDD or Time Division Duplex where spectrum is assigned in a single band for both uplink and downlink.

This database of spectrum is available on each Country Profile page displaying on the the assignments for that country. Changes made here will reflect on the country pages and vice versa.
