TD LTE technology has begun to enter the international competition with the FDD

MWC2015 on the Mobile World Congress, ZTE joint China Mobile and United States Qualcomm successfully demonstrates industry's first three commercial Terminal chip-based TD-LTE downlink carrier aggregation (CA), which means Chinese leading TD-LTE standards keep pace with the development of mobile communication technology in the world.

China TD-LTE facing adverse situation

China is world maximum of mobile communications market, but 1G, and 2G mobile communications technology standard are Europe developed of, equipment expensive, China also have paid high of patent fee; 3G times China launched has TD-SCDMA standard, but due to technology than European of WCDMA and United States of CDMA standard mature, in China of TD-SCDMA Industry chain mature in 2009 input commercial of when, has than global commercial WCDMA network late has near 10 years time. Because the TD-SCDMA Industry chain as far as the other two mature and final TD-SCDMA in China.

First edition published the March 2009 4G standards. 4G has two branches, one is Europe's leading LTE-FDD, a Chinese-dominated TD-LTE, United States that he pushed the UMB and WIMAX has lost to Central Europe to promote the LTE standard.

Commercial 3G in China in December 2009, Northern Europe's largest operator, Telia Sonera LTE-FDD enabled network, November 2010 Japan operator NTT DOCOMO commercial LTE-FDD commercial network, in December of the same year United States carriers Verizon business of the world's first large-scale LTE-FDD network.

2014 mobile commercial TD-LTE networks, commercial LTE-FDD has 4 years late compared to May 2014, up over 90% LTE-FDD network, global support FDD terminals around the 4G end total style of 90%. TD-LTE standard in China seems to be repeating the 3G story of the TD-SCDMA standard, far weaker than the European standards LTE-FDD.

China Mobile push TD-LTE development

Mobile is China maximum of mobile communications operators, is global scale maximum of mobile communications operators, 2G standard because mobile select has GSM and makes GSM won has and CDMA standard of competition capital; 3G standard TD-SCDMA standard in China Mobile of efforts promoted Xia, through hard in 2013 also made has considerable of results, in that a years TD-SCDMA of phone sales equivalent to China market Shang WCDMA and CDMA phone sales of sum, Successfully reached the Ministry handed over to China Mobile, one of the three tasks.

China Mobile took on TD-LTE standard one year, effectively promoted the development of TD-LTE industry. 2014 construction of China Mobile has more than 600,000 TD-LTE base stations to reach more than 700,000, the world 4G more than 40%,TD-LTE base stations number of users reaches 90 million households, chip companies, cell phone companies at home and abroad to support TD-LTE standard, TD-LTE industry chain is strong.

ZTE joint China Mobile and United States Qualcomm successfully demonstrates industry's first three commercial Terminal chip-based TD-LTE downlink carrier aggregation (CA), speed up to 330mbps and shows only last December, Ericsson LTE-FDD three-carrier aggregation, rate of 375mbps, TD-LTE this proof technology keep pace with LTE-FDD.

China's TD-LTE standard the opportunity to enter the international market

Building a WIMAX network operators in the world are willing to build TD-LTE network, United States SPRINT 100M TDD spectrum, but because there is no large-scale network demonstration, foreign operators hung back.

In the past year, both at home and abroad there is a sound, speed and maturity of said LTE-FDD is better than TD-LTE, and now TD-LTE has been prepared for three carrier business, speed and LTE-FDD of the three carriers, technology gap and LTE-FDD are micro-and TD-LTE and LTE-FDD competition in the international market. China Mobile's network coverage quality, achieve a TD-LTE mass coverage, fears of massive coverage TD-LTE standard concerns. This demonstration of TD-LTE network of China Mobile, TD-LTE standards to international markets has been cleared the haze.

After the large-scale construction and development of China Mobile users, TD-LTE terminal style has been greatly enriched, to domestic and foreign mobile phone supports both TD-LTE and LTE-FDD the purpose of industry does not need to worry about. China has a TD-LTE essential patents, China is the largest country in the world manufacturing output, push TD-LTE standards into the international market will help China make to the world, achieve China's transformation, the value of China-made.

Development of TD-LTE technology is an example of China's progress, we are no longer the only country producing low-end products, has been able to propose standards, capable of promoting industry matures, and to promote the development of technology, and keep pace with the technological development in Europe and America.

Samsung Galaxy S6

On the whole, the new Samsung Galaxy S6 material just as Apple launched iPhone 4 o'clock it was amazing. Volume-high location and handset design and overall did not match, is the place where I feel will improve on the design. Functions, fingerprints and photographs are very powerful, I heard more than one peer praise these two features "as well as iPhone" or even "better than iPhone". Systems experience, Samsung and all other international companies choose to be consistent--move closer to the native Android system, compared to before the Samsung fully customized systems, more modern, more fresh, naturally, was easier to use.
