TD-SCMDA is a 3G technology used so far only in China, and is a Time Division synchronous version of CDMA, the code division multiple access protocol which, in different variants, forms the basis of all 3G cellular technologies. TD-SCDMA can dynamically adjust the number of timeslots used for downlink and uplink, which makes it strong for broadband, when users are often uploading data. TD-SCDMA was designed with help from Germany’s Siemens and by Chinese interests. The largest cellular operator in the world by subscriber numbers, China Mobile, operates the only TD-SCDMA network, while its local rivals us W-CDMA and CDMA 2000 networks, so all three major technologies are represented in China. Eventually all of these networks are likely to move to LTE. TD-SCDMA was first proposed in 2006, but first implemented in 2009 and by 2011 it had just 20 million of its 600 million customers using TD-SCDMA.
