Samsung Galaxy S4 Mini and Galaxy S 4

It hasn't been easy to bridge differing LTE network types in one phone; ZTE's attempt requires a reboot, for example. Samsung claims to have solved that problem with new dual-mode LTE versions of the Galaxy S 4 and Galaxy S4 Mini. Both devices can switch between the common FDD-LTE standard and TDD-LTE without restarting, and they'll automatically hand over any ongoing data sessions or voice calls. The advantages are potentially huge for both roaming and bandwidth -- travelers are more likely to stay on 4G, and providers running both FDD and TDD can switch customers to whatever network has the most capacity. Samsung hasn't said where and when the dual-mode Galaxies will be available, although TDD-LTE's worldwide reach (including the US) suggests that the smartphones could soon be commonplace.

Samsung Announces GALAXY S4 and GALAXY S4 mini With the world's first TDD-LTE and FDD-LTE Seamless Handover Technology

Samsung accelerates global LTE market possibilities with world's first commercial dual-mode LTE handover devices

Seoul, Korea – Jul 29, 2013 – Samsung Electronics today announced the world's first commercial devices capable of TDD-LTE (Time-Division Duplex) and FDD-LTE (Frequency Division Duplex) seamless handover technology. Samsung will launch TDD/FDD Dual Mode LTE versions of the Samsung GALAXY S4 and Samsung GALAXY S4 mini, which will enable continuous and seamless voice and data communications even as the devices switch between two different types of LTE networks.

"Samsung continues to accelearate global LTE market deployment, addressing technical challenges faster than anyone else. With today's TDD/FDD LTE seamless handover devices announcement, Samsung again demonstrates the company's commitment to driving better, more convenient customer experiences," said JK Shin, co-CEO and president of the IT & Mobile division of Samsung Electronics. Shin added, "The first commercially available TDD/FDD seamless handover devices will allow customers to fully enjoy the benefits of fast mobile data communications no matter where they are."

While the majority of the global LTE market is based on FDD-LTE technology, TDD-LTE, the alternative LTE technology, is expected to see increased adoption in the US, China, Australia, Middle East, Northern and Eastern Europe, and Southwest Asia, and to gain a more pronounced position in the global LTE market. Seamless handover between FDD-LTE and TDD-LTE networks is a critical feature for end-user customers and mobile operators, especially in markets where the both technologies are deployed.

As a market pioneer in LTE technology, Samsung's new support of seamless handover with the GALAXY S4 will enable even more convenient, ultra-fast mobile data communications, and provide users with smooth and seamless data communication without delays or interruptions while browsing or on calls during network handover. In addition, the seamless handover will enable a true global LTE roaming solution, enabling users to enjoy fast and rich multimedia data communication wherever they are. For mobile operators, use of both TDD-LTE and FDD-LTE frequencies can help them effectively manage data traffic and sustain quality of service. For example, mobile operators can allocate data traffic from FDD-LTE frequency to TDD-LTE frequency when FDD-LTE frequency is heavily loaded.

Samsung is the first player in the global mobile industry to provide dual-mode (TDD-LTE/FDD-LTE) smartphones.

Samsung will continue to launch TDD-LTE devices in other markets throughout third quarter.
