Samsung Electronics announced the commercial launch in Korea first in the world devices, which can work simultaneously with the technology of TDD-LTE (Time-Division Duplex) that use the same frequency range for both channels will be separated in time, and FDD-LTE (Frequency Division Duplex), which involves the use of two frequency bands. Samsung introduced LTE version of the GALAXY S4 and GALAXY S4 mini that can switch between TDD-LTE and FDD-LTE networks, providing uninterrupted voice and data transmission in the highest quality.
As noted in the company, while most of the world's LTE market is based on FDD-LTE, an alternative technology of TDD-LTE is gaining momentum in the United States, China, Australia, the Middle East, Northern and Eastern Europe, southwestern Asia. The ability to easily switch between networks FDD-LTE and TDD-LTE is becoming one of the most important benefits for both end users and mobile operators, especially in markets where both technologies are deployed in parallel.
Technology Support TDD-LTE and FDD-LTE, which is implemented in smartphones Samsung GALAXY S4 and GALAXY S4 mini will make the process of data transfer faster and more convenient, and also will help to avoid delays and interruptions when viewing web pages or answering calls. In addition, this solution will provide truly global LTE roaming, making the transmission of any multimedia data faster, regardless of user location. For mobile operators and the use of TDD-LTE and FDD-LTE frequencies will help to more effectively manage the data transfer process and support service quality at the highest level. For example, mobile operators will be able to route the network traffic with FDD-LTE frequency to TDD-LTE, when the FDD-LTE network is excessively loaded.
