Vendors scramble for LTE header

Communications Industry newspaper reporter Lu Zi month with the LTE scale test, the competition among manufacturers also tends to white-hot.　　At present, most manufacturers have completed the construction of scale test network and opened the first LTE call. "At present, the companies are very competitive." Manufacturers are scrambling to get through the first LTE phone, LTE scale test progress may be related to some manufacturers ' jobs. "Recently, the reporter asked about the progress of LTE scale test, the relevant people said," the manufacturers are trying to build a scale test network, but the progress is not the same, is expected to have phased results in two months. "LTE scale test has been a concern of the industry. Xinsheng, an inspector of the Ministry of Industry and Information Technology, said recently that the focus of the wireless sector is becoming less hot, and LTE progress is undoubtedly the most important thing.　　Huang, dean of China Mobile Research Institute, also said that LTE is now under threat from Fddlte and must speed up the development of LTE to occupy the mainstream market before Fddlte. The test result is better the Ministry of Industry and Information technology has set up a LTE working group to promote the LTE test, and currently has 31 members.　　In addition to the relevant institutions, alliances and 3 operators, but also includes 11 system equipment manufacturers, 10 chip manufacturers, 3 terminal manufacturers, 1 instrument manufacturers. Among them, the system equipment manufacturers including Huawei, ZTE, Datang Mobile, Nokia Siemens Communications, Shanghai Bell, Ericsson, Putian, new mail, Beacon Communication, Samsung and other 11, the early entry of 8. Each system equipment manufacturer will build 100 Acer stations and 10 micro-base stations.　　6 cities except Xiamen only NSN a manufacturer, Shanghai, Hangzhou, Guangzhou, Shenzhen, Nanjing each has two manufacturers. Industry-renowned chip manufacturers are basically shortlisted for this scale test.　　According to relevant sources, the current test situation, Heiss and creative video performance better than other chip manufacturers. It is reported that the scale test of 6 cities is divided into core test content and enhanced test content. The core test contents include: LTE terminal and its IoT, wireless network performance, multi antenna technology, core network and load capacity, 2g/3g/td-lte business coordination capability, terminal consistency.　　The enhanced test content includes: 8 days line, multi-band antenna test, SON, indoor distribution system, wireless interference test, etc. Among them, the content of smart antenna is added for the first time in the function and performance test of 2.6GHz system.　　Ministry of Industry and Information Technology, Deputy chief engineer of the Institute of Telecommunications Wang Zhiqin, the overall test results are better. The manufacturers ' progress is not the same. System equipment manufacturers in the LTE scale test competition is becoming white-hot.　　At present, most of the manufacturers have completed the scale of the test network construction, and related testing, but the test progress is different. Ericsson completes the 2x2 test of LTE terminal and system on March 30After the trial, shortlisted scale test. April 6, open the first phone, business for video playback and FTP downloads. April 27, the first demonstration center was built in Shenzhen Fortune Building. May 3 to 4th based on the PTN layer three transmission, the successful completion of the core network and base station linked. May 16, Ericsson support Shenzhen Mobile "Wireless City" launch will be successfully demonstrated based on LTE network video on demand, that is, video conferencing, videoconferencing and other high-definition video business. June 7 to 9th, the successful completion of Ericsson at the Ngmn summit based on the LTE System business demo.　　So far, Ericsson has almost completed the installation and deployment of the entire test network, and is currently conducting core network testing. NSN in Hangzhou in early May opened the first LTE call, 517 telecom days before the completion of the Hangzhou LTE scale commercial network construction, network coverage including the West Lake Scenic area of nearly 41.5 square kilometers.　　LTE's Internet peak speed reaches hundreds of megabytes per second, which can host broadband data services such as online high-definition video conferencing. As of May 31, NSN has completed the construction of 100 outdoor sites in Xiamen.　　In the construction of the scale test net, NSN will test the new technologies such as liquid radio and flexi-race active antenna. Huawei in early April and Guangdong Mobile in Shenzhen completed the first batch of LTE base station and the core network, the deployment of the host network. And in Shenzhen to achieve the scale of the experimental network of the first LTE wireless connection, the scene shows the LTE data card based high-speed download and multi-channel high-definition video business.　　At present, Huawei has completed the core network of EPC test, all use cases using third-party instrumentation and real Usim card for testing, and 100% through. Shanghai Bell has completed the core network and part of the wireless base station deployment, and on May 2 opened the first LTE call.　　The LTE test network, which is provided by Shanghai Bell, covers the Zhangjiang High-tech Park and Lujiazui Financial district. Datang Mobile in Nanjing to undertake the LTE network construction, on April 8 opened the LTE business, the implementation of high-speed downloads, high-definition video playback business and other demonstrations.　　It is reported that Datang Mobile and China Mobile jointly innovative 8-day dual-beam beamforming technology is widely used in this scale test. ZTE's LTE scale test network has been opened in Guangzhou and the core network entry test has been completed.　　In Guangzhou, the covering area of 13 square kilometers contains 2 CBD, 2 universities, 10 tunnels, 7 sports venues, 4 city villages, 600 high-rise buildings with 30 floors, more than 10 important trunk roads and Pearl River waters. Terminal fever is a difficult Point TD Alliance Secretary-General Yang Hua has said that multimode terminals are the key to the development of LTE industry. Reporter recently asked the LTE scale test of the terminal test situation, the relevant person said, at present, Multimode Terminal has been added to the test, how to solve the terminal heat problem is the current terminal test face the biggest challenge。 At present, multimode terminals have become the trend of terminal development. At the World Mobile Communications Conference in 2011, China Mobile's chairman, Mr Wang, said China Mobile would plan to launch a Gsm+td+lte multi-mode terminal to ensure compatibility of LTE with 3G and 2G networks. The future of the multimode chips including LTE will be gradually introduced.　　According to the scale technical test arrangement, the terminal test will be launched in September this year. Recently, Marvell and other TD chip manufacturers plan to launch td/wcdma/gsm three-mode mobile phone chip, which will make TD mobile phone roaming costs to the same as WCDMA mobile phones. China Mobile Sheng said the goal of the Chinese move is to achieve TDD/FDD common mode LTE terminals in March 2012.
