China Mobile announced two major 4G systems for Bidirectional roaming

Yesterday, China Mobile led the 4G network standard TD-LTE again exposed heavyweight news, China Mobile announced that the standard in Hangzhou successfully achieved two-way roaming with Hong Kong FDD-LTE network; in addition, netease Technology in Hangzhou bus line on the test of the TD-LTE hot spots, the maximum rate of nearly 9 Mbps.

Two major 4G systems for roaming

China Mobile Vice President Li zhengmao in yesterday's "TDD night" announced that the Hangzhou TD-LTE network has been with the Hong Kong FDD-LTE network roaming, which means that the two major 4G systems first to achieve two-way roaming.

Executives of Zhejiang mobile and Hong Kong Mobile demonstrated the voice and video call functions between the two systems at the scene. in Hangzhou, they used the Hong Kong FDD network to enable Youtube to play HD videos smoothly.

Li zhengmao said, FDD-LTE and TD-LTE to achieve two-way roaming is a significant progress in the development of 4G, the next step will focus on Seamless Roaming and dual-mode terminal roaming and other work.

Li Yue, President of China Mobile, said previously that TD-LTE intends to trial commercial use in the Mainland in 2013, its base stations will exceed 0.2 million, with more than 0.2 billion user coverage.

In 2011, China Mobile identified Shanghai, Hangzhou, Nanjing, Guangzhou, Shenzhen, Xiamen and other 6 places for TD-LTE pilot, This year Hangzhou in the country first started TD-LTE bus hot experimental network. According to statistics from Huawei technical experts, as of June 3, the number of 4G-based Wi-Fi connections in Hangzhou had nearly 43000 in a single week, the total traffic in a single week reached 3063 GB, and the number of active users in a single week reached 6500.

Tested TD-LTE: up to 9 Mbps

During the test, the web page with a large volume of data is faster than 3g, the buffer time for playing online HD videos is relatively short, and the video is not choppy during the playing process.

It is understood that each B1 bus were deployed on two TDFi TD-LTE signal into WiFi signal, each device can support up to 64-bit users at the same time.

According to Huawei technical personnel, there are currently 700 LTE base stations in Hangzhou, and it is planned to reach 2500 by the end of this year, covering the main city, upgrading a TD-SCDMA base station to a TD-LTE base station also takes only a few minutes ".

It is understood that the deployment of TDFi in Hangzhou will cover all bus stations and cover taxis, parks, squares, residential areas and malls.
