LTE frequency bands
Long Term Evolution (LTE) telecommunications networks use several frequency bands with associated bandwidths.

Frequency bands and channel bandwidths 
From Tables 5.5-1 "E-UTRA Operating Bands" and 5.6.1-1 "E-UTRA Channel Bandwidth" of the latest published version of the 3GPP TS 36.101, the following table lists the specified frequency bands of LTE and the channel bandwidths each band supports.

Deployments by region 

The following table shows the standardized LTE bands and their regional use. The main LTE bands are in bold print.  Not yet deployed are not available (N/A).  Partial deployments varies from country to country and the details are available at List of LTE networks.
 Networks on LTE bands 7, 28 (LTE-FDD) are suitable for global roaming in ITU Regions 1, 2 and 3.
 Networks on LTE bands 1, 3 (LTE-FDD) are suitable for roaming in ITU Regions 1 and 3, Costa Rica and Brazil and partially in some Caribbean countries.
 Networks on LTE band 20 (LTE-FDD) are suitable for roaming in ITU Region 1 only.
 Networks on LTE band 5 (LTE-FDD) are suitable for roaming in ITU Regions 2 and 3. 
 Networks on LTE bands 38, 40 (LTE-TDD) may allow global roaming in the future (ITU Regions 1, 2 and 3).
 Networks on LTE band 8 (LTE-FDD) may allow global roaming in the future (ITU Regions 1, 2 and 3).
 Networks on LTE bands 2 and 4 (LTE-FDD) are suitable for roaming in ITU Region 2 (Americas) only.
