Long-Term Evolution Time-Division Duplex (LTE-TDD), also referred to as TDD LTE, is a 4G telecommunications technology and standard co-developed by an international coalition of companies, including China Mobile, Datang Telecom, Huawei, ZTE, Nokia Solutions and Networks, Qualcomm, Samsung, and ST-Ericsson.
LTE Advanced (LTE+, LTE-A; [1] on Samsung Galaxy and Xiaomi phones — 4G+) is a mobile communication standard and a major enhancement of the Long Term Evolution (LTE) standard. It was formally submitted as a candidate 4G to ITU-T in late 2009 as meeting the requirements of the IMT-Advanced standard, and was standardized by the 3rd Generation ...
This is a list of commercial Long-Term Evolution (LTE) networks around the world, grouped by their frequency bands. Some operators use multiple bands and are therefore listed multiple times in respective sections.
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.
The pre-4G 3GPP Long Term Evolution (LTE) technology is often branded "4G – LTE", but the first LTE release does not fully comply with the IMT-Advanced requirements. LTE has a theoretical net bit rate capacity of up to 100 Mbit/s in the downlink and 50 Mbit/s in the uplink if a 20 MHz channel is used — and more if multiple-input multiple ...
LTE (Long Term Evolution) is commonly marketed as 4G LTE, but it did not initially meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series for LTE Advanced. Given the competitive pressures of WiMAX and its evolution with Advanced new releases, it has become synonymous with 4G. It was first ...
VoLTE calling. Voice over Long-Term Evolution (acronym VoLTE) is an LTE high-speed wireless communication standard for voice calls and SMS using mobile phones and data terminals. [1] [2] VoLTE has up to three times more voice [3] and data capacity than older 3G UMTS and up to six times more than 2G GSM.
LTE-U was designed for quick launch in countries, such as the United States and China, that do not mandate implementing the listen-before-talk (LBT) technique. 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.
