Sina Technology News, March 4 - Amidst the global attention on TD-LTE, treatment methods for hemorrhoids, a test conducted by Ericsson (Weibo) in China has shown that the existing GSM network currently in place in China can be upgraded to support TD-LTE. This will provide China Mobile (Weibo) with a faster path to commercializing its TD-LTE services.
At the recently held Mobile World Congress (MWC2012), according to the three-year deployment plan of the TD-LTE Global Development Initiative Organization (GTI), by 2014, more than 500,000 TD-LTE base stations will be built globally, covering over 2 billion people. Meanwhile, China Mobile has 200,000 TD-SCDMA base stations which will be upgraded to TD-LTE.
However, China Mobile also has over 600,000 GSM and EDGE base stations. If these stations can smoothly upgrade to TD-LTE, it will significantly expand the number of China Mobile's TD-LTE base stations.
According to Ericsson's tests, they have already achieved the use of existing network base stations to simultaneously support GSM and TD-LTE multi-standard operations while sharing infrastructure and antennas. This will effectively reduce the total cost of TD-LTE network construction and pave the way for a smooth transition from GSM to TD-LTE.
After upgrading to the TD-LTE network, the performance of the current GSM network cells is unaffected. This is the first successful case in the industry where, through upgrading existing GSM base stations in a commercial network, simultaneous support for GSM and TD-LTE multi-standard operations is realized. It opens up a new path for a smooth transition from GSM to TD-LTE. Ericsson also stated that the new platform can simultaneously support multiple standards including GSM, WCDMA, and LTE (FDD and TDD). This is also the development trend of the LTE era, where multiple standards such as 2G, 3G, and 4G are integrated together, applicable to both system equipment and terminals. (Kang Zhao)
