Samsung Electronics has announced this Monday to launch TDD/FDD dual mode LTE versions of Samsung GALAXY S4 and Samsung GALAXY S4 mini. The Taiwanese tech giant states that these will be the world’s first commercial devices that deploy 4G LTE (Long Term Evolution) network with latest Time-Division Duplex (TDD) and (Frequency Division Duplex (FDD) seamless handover technology methods.
What dual-mode actually means? Actually a dual-mode phone has the ability to work with different types of high-speed 4G LTE networks. The dual-mode phone users can do continuous and seamless voice and data communications by switching between different types of LTE networks using FDD-LTE or TDD-LTE deployment methods.
President and co-CEO of the IT & Mobile division of Samsung Electronics, JK Shin said, “Samsung continues to accelerate 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. 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.”
Samsung is a pioneer in LTE technology and now it claims to be "the first player in the global mobile industry to provide dual-mode (TDD-LTE/FDD-LTE) smartphones." GALAXY S4 phones will be the world’s first commercial devices that come with seamless handover technology. But china's ZTE had already launched its dual-mode LTE smartphone 'Grand Era' last year in Hong Kong, China. So we cannot say that Samsung is the first company to deploy dual mode technology.
Taiwan's smartphone maker will launch TDD-LTE devices in markets throughout third quarter. Specs of these two S4 phones will remain same except adding dual-mode LTE TDD/FDD support. No such pricing details are given.
