  • TD-SCDMA Technology

    TD-SCDMA Technology TD-SCDMA (time division - synchronous code division multiple access) is a cellular technology based on the combination of a TDMA (time division multiple access) component and a CDMA (code division multiple access) component. Additionally, unique synchronization mechanisms are foreseen for optimizing the time division duplex (TDD) mode of operation. The uplink and downlink are separated

  • TETRA / TETRA 2 Technology

    TETRA / TETRA 2 Technology In practice, the open TETRA standard is a suite of standards covering different technology aspects, e.g. air interfaces, network interfaces and their services and facilities. TETRA mobile stations (MS) commonly communicate using the radio trunking infrastructure (switching & management infrastructure, SwMI) made of TETRA base stations (TBS). Alternatively, direct communications

  • WCDMA / HSPA / HSPA+ Technology

    WCDMA / HSPA / HSPA+ Technology Technology Overview Universal mobile telecommunication system (UMTS) networks based on wideband code division multiple access (WCDMA) have been deployed worldwide as 3rd generation mobile communications systems. UMTS provides a clear evolutionary path to high-speed packet access (HSPA). HSPA refers to the combination of high-speed downlink packet access (HSDPA) and high-speed

  • WiMAX™ Technology

    WiMAX™ Technology Flexible, accurate and fast: Rohde & Schwarz test solutions WiMAX™ (Worldwide Interoperability of Microwave Access) is based on modern communications technologies, such as OFDMA and MIMO. This establishes WiMAX™ as a cellular broadband standard, providing high performance in data rate, mobility and cell size. VoIP and roaming capabilities are additional focus areas for WiMAX™. This

  • CMMB Technology

    CMMB Technology In order to create a uniform standard for mobile TV reception in China, the Chinese broadcasting authority SARFT (State Administration of Radio Film and Television) has required mobile radio operators to use a uniform standard. China has standardized its own development for mobile television broadcasting. The standard is called CMMB (Chinese Mobile Multimedia Broadcasting) and was formerly

  • SDB-T 1 Seg Technology

    SDB-T 1 Seg Technology A special form of ISDB-T and ISDB-TB is the 1-segment mode, which is used specially for mobile reception by means of handhelds. The narrow spectrum permits the reception of TV and audio content at low energy consumption levels. The channel is split into 13 sub-bands (segments). The 13 segments in the OFDM spectrum can be combined to create segment groups called "layers." For

  • T-DMB Technology

    T-DMB Technology T-DMB and T-DMBVR are extensions of the DAB standard for the transmission of video to mobile receivers. This requires a special T-DMB A/V encoder. The RF coding and frequencies used are identical to those for DAB. Existing DAB and DAB+ transmitters can be used for T-DMB as well. Baseband coding differs from DAB and DAB+ in two aspects: 1) the multiprotocol encapsulation of MPEG-4 H

  • DVB-S2 Technology

    DVB-S2 Technology The DVB-S2 standard (EN 302 307) defines the second-generation modulation and channel coding system for satellite TV to make use of the improvements that have emerged since the publication of the DVB-S standard. DVB-S2 is a single, very flexible standard covering a variety of applications by satellite. DVB-S2 is the next logical step in the continuous development of DVB-S. Innovative

  • DVB-S2X Technology

    DVB-S2X Technology The DVB-S2 standard (EN 302 307) defines the second-generation modulation and channel coding system for satellite TV to make use of the improvements that have emerged since the publication of the DVB-S standard. DVB-S2 is a very flexible standard covering a variety of applications by satellite. DVB-S2X The original DVB-S2 has been extended with part 2, which defines the additional

  • XM Satellite Technology

    XM Satellite Technology XM satellite is a terrestrial, repeater-assisted satellite digital audio radio service (SDARS) in the United States for nationwide mobile car reception in CD quality. This is why separate traffic and weather channels are available alongside normal radio entertainment. Parts of the offered program are encrypted so that users must have an electronic serial number (ESN) radio ID
