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 telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for cellular mobile devices and data terminals. It is considered to be a "transitional" 4G technology, [1] and is therefore also referred to as 3.95G as a step above 3G.
QoS Class Identifier (QCI) is a mechanism used in 3GPP Long Term Evolution (LTE) networks to ensure carrier traffic is allocated appropriate Quality of Service (QoS). Different carrier traffic requires different QoS and therefore different QCI values. QCI value 9 is typically used for the default carrier of a UE/PDN for non privileged subscribers.
For technical details on LTE and a list of its designated operating frequencies, bands, and roaming possibilities, see LTE frequency bands. Bands 33 to 44 are assigned to TDD-LTE. Note: This list of network deployments does not imply any widespread deployment or national coverage.
LTE-M or LTE-MTC ("Long-Term Evolution Machine Type Communication") is a type of low-power wide-area network radio communication technology standard developed by 3GPP for machine-to-machine and Internet of Things (IoT) applications.
4G eLTE is Huawei's proprietary derivative of the LTE standard, the "e" standing for "enhanced", intended to provide wireless broadband transmission with peak downlink speeds of 50 Mbit/s and 20 Mbit/s uplink per site in 5 MHz, 10 MHz and 15 MHz frequencies.
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).
LTE-U would allow cellphone carriers to boost coverage in their cellular networks, by using the unlicensed 5 GHz band already populated by Wi-Fi devices. LTE-U is intended to let cell networks boost data speeds over short distances, without requiring the user to use a separate Wi-Fi network as they normally would.
