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.
In addition to radio frequencies used to connect handsets with cellular base stations, other parts of the radio spectrum are used to interconnect base stations and the wired telephone network. Some frequency bands may be vulnerable to interference by existing services in adjacent frequency bands, such as UHF television broadcasting.
For technical details on LTE and a list of its designated operating frequencies, bands, and roaming possibilities, see LTE frequency bands. Bands 33 to 53 are assigned to TDD-LTE. Note: This list of network deployments does not imply any widespread deployment or national coverage.
Mobile networks based on different standards may use the same frequency range; for example, AMPS, D-AMPS, N-AMPS and IS-95 all use the 800 MHz frequency band. Moreover, one can find both AMPS and IS-95 networks in use on the same frequency in the same area that do not interfere with each other.
LTE's Enhanced Multimedia Broadcast Multicast Services (E-MBMS) provides transport features for sending the same content information to all the users in a cell or to a given set of users (subscribers) in a cell using a subset of the available radio resources with the remaining available to support transmissions towards a particular user (so-called unicast services).
While LTE-FDD uses paired frequencies to upload and download data, [75] LTE-TDD uses a single frequency, alternating between uploading and downloading data through time. [76] [77] The ratio between uploads and downloads on a LTE-TDD network can be changed dynamically, depending on whether more data needs to be sent or received. [78]
This is a list of commercial Long-Term Evolution (LTE) networks in Europe, grouped by their frequency bands. Some operators use multiple bands and are therefore listed multiple times in respective sections.
4G LTE is the fourth generation mobile phone standard. In urban areas, the 4G uses a frequency band located between 1800 MHz and 2600 MHz, and therefore is quite far from the TV band for causing any type of interference problem. In rural areas, however, the major operators asked to use part of the UHF band.
