At the MWC 2013 tech show, South Korean tech company LG demonstrated its Long Term Evolution Time Division Duplexing (LTE TDD) service. Now, LG has announced that they will be rolling out their LTE TDD smartphones worldwide starting from Saudi Arabia with Optimus G smartphones of mobile carrier STC. The handsets based on the same technology will also be made available in China, India, North America, Japan and Australia with more countries to follow.
Dr. Jong-seok Park, President and CEO of the LG Electronics Mobile Communications Company said "LTE TDD is a superior alternative in some countries due to its flexibility in uploading and downloading content. We're excited to offer consumers LTE TDD capable smartphones based on our unparalleled knowhow in 4G LTE technologies. With the commercial introduction of LTE TDD service, LG will build upon its expertise in 4G LTE by offering future device options utilizing this standard."
Benefits of LTE TDD
LTE TDD is designed to let data be received and transmitted on the same frequency, which according to LG it performs more like home broadband with a narrow band for uploading data and a wider band for receiving data, making it more efficient.
Long Term Evolution Time Division Duplex (LTE TDD) is the version of LTE that uses the TDD modulation scheme in unpaired spectrum, whereby the same frequency channel is used for both downlink and uplink communication and signals are timed to enable smooth delivery of data. In contrast, LTE uses frequency division duplex (FDD) in paired spectrum, with a separate channel for uplinks and downloads.
