Milestone technology innovation prompts TD-LTE to enter the fast lane of accelerated development

A year passed quickly, and the 2013 MAE Asia Mobile Expo was held in Shanghai as scheduled. Looking back at the 2012 MAE exhibition, TD-LTE has attracted much attention and expectations, but after all, it has just started, and it has to face difficulties from various aspects and its own shortcomings; now, after only one year, regardless of the maturity of the industry chain Or large-scale commercial use worldwide, TD-LTE has achieved leapfrog development, and its speed is amazing!

Chips and terminals get rid of shortcomings and make breakthrough progress

Compared with a year ago, chips and terminals have become shortcomings in the development of TD-LTE. Today's TD-LTE chips and terminals have made breakthrough progress. According to GSA statistics, as of April 2013, a total of 166 TD-LTE terminals have been released worldwide, including 16 TD-LTE smartphones, and 79% of the terminals support multi-mode and multi-frequency. Well-known terminal manufacturers have launched TD-LTE products, such as Samsung's Galaxy S3 / S4, Huawei Ascend P1 / D2, as well as Nokia, Motorola, Sharp and HTC. TD-LTE chips are developing rapidly. All chip manufacturers have at least launched dual-mode (LTE TDD / FDD) chips. Among them, Qualcomm has introduced six-mode (full-mode) chips, and HiSilicon has launched five-mode chips.

As the world's largest LTE supplier, Huawei has invested in the development of TD-LTE on an end-to-end scale. Huawei HiSilicon has launched a series of TD-LTE chips such as Balong710, Balong910 and Balong720. It uses a 28nm single-chip system and fully supports dual-stream beamforming, voice fallback, carrier aggregation, Hetnet and downlink Comp. , Huawei also provides a variety of TD-LTE terminals-as of April 2013, Huawei has released more than 30 TD-LTE terminals (GSA statistics), setting a number of global firsts.

The pace of commercialization on a global scale is accelerating, and the construction of domestic test networks is accelerating

Recall that when the MAE Expo was held last year, there were only five commercial TD-LTE networks worldwide, and the construction of a large-scale trial network in China was just beginning. Now that one year has passed, the commercial scope and speed of TD-LTE has been accelerating. As of April 2013, a total of 42 TD-LTE commercial networks have been deployed worldwide, of which 15 are officially commercialized by GSA and TD-LTE users Nearly 3 million. Among these 15 officially commercial networks, Huawei participated in the construction of 10 networks including Japan ’s Softbank and UK UKB.

Among them, in May 2012, Saudi Mobily commercialized the world's first WiMAX / LTE dual-mode network, all using Huawei's SingleRAN WiMAX / LTE solution and terminal. As of April 2013, the total number of TD-LTE data cards and CPE users has exceeded 1.6 million; in October 2012, UKB launched the world ’s first commercial service for 3.5G TD-LTE network. The second phase expansion will cover the core area of ​​London and will be exclusively supplied by Huawei end-to-end. In December 2012, Sri Lanka Colombo, the capital, launched the TD-LTE commercial service, which uses CPE to provide data and VOIP services. All equipment is also provided exclusively by Huawei.

At the same time, the speed of domestic TD-LTE scale trial network construction is also accelerating. China Mobile's task of deploying 20,000 base stations in 13 cities is accelerating. Among them, Hangzhou and Wenzhou, which were built by Huawei, have taken the lead in commercial trials, and the number has been broken. At the same time, the two cities of Shenzhen and Guangzhou also started trial commercialization at the end of February 2013. In addition, China Mobile has launched a tender for 20 billion TD-LTE equipment, and the number of base stations is close to 200,000.

Whether it is domestic or foreign, the commercial deployment of TD-LTE is showing an accelerated trend. As one of the important 4G standards, the technical advantages and commercial value of TD-LTE have been generally recognized by the industry. In 2013, global TD-LTE The base station scale is expected to reach 350,000, and by 2014, this number is expected to be raised to 500,000.
