The Single Wire Protocol (SWP, ETSI TS 102 613) is used as direct interface between the mobile phone's Contactless Front-end (CLF) and the mobile phone's (U)SIM card.
There are two standardised data exchange protocols defined in ISO/IEC 7816-3 for the communication between a Smart Card and a terminal: the byte-oriented half duplex transmission protocol T=0 and the block-oriented half duplex protocol T=1. The character-oriented T=0 protocol is very simple constructed and has a low memory capacity (about 300 Byte). The block-oriented T=1 protocol is a half-duplex protocol and works with error detection (EDC) at the end of block. The memory requirement is about 1.100 Byte.
This contactless transmission protocol is standardised by ISO/IEC 14443-4. T=CL is a complete protocol stack. CL stands for contactless. The name structure is derived from the ISO 7816 protocols T=0 and T=1.
TD-SCDMA (Time Division Synchronous Code Division Multiple Access) is an air interface found in UMTS mobile telecommunications networks in Asia as an alternative to W-CDMA. It was developed by the CATT (China Academy of Telecommunications Technology) in collaboration with Datang and Siemens to be accepted by the IT as one of the five IMT-2000 standards.
Universal Integrated Circuit Card is a Smart Card used in mobile terminals to ensure the integrity and security of the subscriber's personal data. Several application (SIM, USIM, CSIM ...) make it possible to give access to several networks with the same card.
The Universal Mobile Telecommunications System is one of the 3rd generation mobile phone technologies that allow a higher data rate than GSM does. Originally UMTS was standardised by ETSI but today it is supported by 3GPP.
The UMTS SIM Application Toolkit (USAT) is based on SAT but is enhanced for the features provided by the UMTS technology. It enables the USIM to drive the UMTS handset and enables an interactive exchange between a network application and the user. The USAT function is located on the USIM card.
A Universal Subscriber Identity Module (USIM) stores subscriber information, UMTS authentication information and provides storage space for text messages and phone book contacts.
The Wideband CDMA (W-CDMA) is a mobile phone system for 3G that uses a frequency channel of 5MHz which allows an increasing data transmission rate. All users operate over the same channel using the CDMA multiplexing technique
