Deployments by region[edit]
The following table shows the standardized LTE bands and their regional use. The main LTE bands are in?bold?print. Networks on LTE-bands 1, 3, 7, 28 (FDD-LTE) or 38, 40 (TDD-LTE) are suitable for future global roaming in ITU Regions 1, 2 and 3.•Networks on LTE-band 8 (FDD-LTE) may allow global roaming in the future (ITU Regions 1, 2 and 3) (Long-term perspective).
•Networks on LTE-band 20 (FDD-LTE) are suitable for roaming in ITU Region 1 (EMEA) only.
•Networks on LTE-bands 2 and 4 (FDD-LTE) are suitable for roaming in ITU Region 2 (Americas) only.
