This blog post is by Paul Pan from the Nokia Siemens Networks team in China.
On September 19, 2012, Nokia Siemens Networks successfully completed the 19th site upgrade from TD-SCDMA (3G) to TD-LTE (4G) and conducted the first TD-LTE call in the dual mode field trial network of China Mobile’s Beijing branch (Beijing Mobile).
This is a clear sign of progress in the TD-LTE evolution in China where Nokia Siemens Networks is leading the way with upgrades of the existing 1.9 GHz frequency TD-SCDMA technology to TD-LTE. From the start of the process, we have fully supported China Mobile’s network evolution to the TDD mode of LTE.
With its dual mode field network, Beijing Mobile will be able to conduct tests of coverage, throughput, delay, reselection, handover and interference. The results will demonstrate how they can deliver high capacity TD-LTE networks and services quickly and cost effectively.
Other recent activities in the Greater China region included the demonstration of Nokia Siemens Networks’ 1.9 GHz and 2.6 GHz dual mode TD-LTE co-site solution at its new regional head office. Guests gave high marks to the demo, which they watched closely and discussed in detail with us.
China Mobile is planning to upgrade about 400,000 TD-SCDMA base stations to TD-LTE in the near future. To support this evolution, Nokia Siemens Networks is conducting large scale 2.6 GHz TD-LTE field trials in two major cities in China. Nokia Siemens Networks has also completed the current round of TD-LTE tests organized by the Ministry of Industry and Information Technology (MIIT), achieving best-in-class results in both phases of the process.
