【简　介】:• GLOBAL 3GPP STANDARD
• COVERS ALL RADIO DEPLOYMENT SCENARIOS
• VOICE AND DATA SERVICES
Jointly developed by Siemens and the China Academy of telecommunications Technology (CATT),
TD-SCDMA is an innovative mobile radio standard for the physical layer of a 3G air interface. It has
been adopted by ITU and by 3GPP as part of UMTS release 4, becoming in this way a global
standard, which covers all radio deployment scenarios: from rural to dense urban areas, from
pico to micro and macrocells, from pedestrian to high mobility.
TD-SCDMA is equally adept at handling both symmetric and asymmetric traffic, making it perfectly
suited for mobile Internet access and multimedia applications.
TD-SCDMA, which stands for Time Division Synchronous Code Division Multiple Access, combines
an advanced TDMA/TDD system with an adaptive CDMA component operating in a synchronous
mode.
