Which frequencies are available for LTE?

 1,3,7, (FDD-LTE) or, (TDD-LTE) are suitable for future global roaming in ITU Regions1,2 and3.

LTE TDD frequency band using in huawei equipment are 1710 - 1810 MHZ

many other frequencies are used but mainly :

Band 20 (800)

Band 3 (1800)

Band 7 (2600)

There are many available bands but here in KSA STC is using 1800 MHz for FDD and 2300 MHz for TDD. 

There are very many frequency bands used for LTE TDD and FDD versions. The spectrum allocated for LTE varies around the world and as a result there many LTE bands and frequency allocations.

There are many Available Bands. In India, we ae using Band 40, Band 3 & Band 5

It's depends on the available frequencies in each countries as in Gulf area they used LTE-1800MHz  & LTE-A 800MHz & LTE 2600Mz.

There are frequency bands available in LTE, for FDD and for TDD, each band is operating in one of the following frequencies:MHz (5 bands),MHz (5 bands),MHz (1 band),MHz (2 bands),MHz (4 bands),MHz (6 bands),MHz (1 band),MHz (1 band),MHz (1 band),MHz (1 bands),MHz (2 bands),MHz (1 band),MHz (1 band).

LTE 1800, LTE2100, LTE 2600

LTE 2100,LTE 2300, LTE 1800 and LTE 900

LTE FDD uses 1800 MHz frequency while LTE TDD uses 2600MHz frequency. Initially LTE Mobile devices supported only FDD.
