LTE Technology Approved by MIIT

Altair Semiconductor inform us currently that after a series of high standard tests conduct by China＇s Ministry of Industry and Information Technology (MIIT), its dual mode FourGee-3100/6200 TDD/FDD-LTE chipset will be used in LTE networks in China under the agreement of MIIT. The decision made by MIIT is based not only in long-term testing but also on the result of wide interoperability and field performance trials which seen by China Mobile over the last year. As is known, Altair Semiconductor is the world's advanced developer of ultra-low power, small footprint and high performance 4GLEE chipset. China＇s Ministry of Industry and Information Technology＇s approval of LTE technology will greatly advanced Altair＇s commercial activities in China. Eran Eshed, Co-Founder and VP of Marketing and Business Development at Altair Semiconductor is so glad that he said ,＂we look forward to extending our footprint in the Chinese market and to building on our partnership with China Mobile＂
ZTE is a pioneer in TDD technology improvement and has carefully guided the enterprise in the commercialization of TD-LTE technologies and systems. The enterprise supplies a variety of 2-, 4- and 8-channel base stations. By the time of Augustin 2011, it had built TD-LTE networks around about 15 nations by means of co-operating with 25 top rated international managers in Asia, the CIS, Europe and India. ZTE even works together with some major chipmakers, such as Qualcomm, Innofidei, Sequans, and Altair to carry out interoperability tests and to give support to the development of the TD-LTE ecosystem.
 TDD functions by means of toggling signal directions over a time interval. This toggling happens very quickly and is also imperceptible to the end user. Thus, TDD are capable of supporting voice and some other symmetrical communication services together with a symmetric data services. TDD may also manage a powerful combination of the two traffic types. The related volume of the downstream and upstream links can be altered simply one direction over the other. This is achieved by offering an even greater time allocation by means of time slots to downstream transmission intervals than upstream. This asymmetry is helpful for communication processes known by unbalanced information flow. An apparent practical application for this particular technique is Internet access in which a end user makes its way into a short message upstream and gets information payloads downstream.
