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.

    1. Frequency-division duplexing (FDD); time-division duplexing (TDD); FDD supplemental downlink (SDL); standalone downlink only (SDO)
    2. User Equipment transmit; Base Station receive
    3. User Equipment receive; Base Station transmit
    1. Uplink restricted to 1627.5–1637.5 MHz and 1646.5–1656.5 MHz
    2. Downlink restricted to 1526–1536 MHz
    3. Downlink between 2180–2200 MHz restricted to intra-band Supplemental Downlink
    4. 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
    5. 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]

      1. Frequency-division duplexing (FDD); time-division duplexing (TDD); FDD supplemental downlink (SDL)
      2. User Equipment transmit; Base Station receive
      3. User Equipment receive; Base Station transmit

      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.
