Frequency bands used by Long Term Evolution networks
Long-Term Evolution (LTE) telecommunications networks use several frequency bands with associated bandwidths.
Frequency bands
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,[1] the following table lists the specified frequency bands of LTE and the channel bandwidths each band supports.
- ^ Uplink restricted to 1627.5–1637.5 MHz and 1646.5–1656.5 MHz
- ^ Downlink restricted to 1526–1536 MHz
- ^ Downlink between 2180–2200 MHz restricted to intra-band Supplemental Downlink
- ^ Duplex spacing depends on whether the Uplink is paired with the lower or the upper part of the Downlink, with the remainder of the Downlink available for use as intra-band Supplemental Downlink
- ^ Carrier aggregation only
Obsolete frequency bands
These bands were defined by the 3GPP, but have never been deployed commercially, supported by commercial devices or are no longer used.[1]
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, 3 and partially Region 2 (e.g. Costa Rica, Venezuela, Brazil and some Caribbean countries or territories.
- 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 roaming suitable for roaming in ITU Regions 1, 3 and partially Region 2 (e.g. Peru, El Salvador, Brazil and some Caribbean countries or territories) in the future.
- Networks on LTE bands 2 and 4 (LTE-FDD) are suitable for roaming in ITU Region 2 (Americas) only.
