High Speed Circuit Switch Data

is a specification for data transfer over GSM networks. HSCSD utilizes up to four 9.6Kb or 14.4Kb time slots, for a total bandwidth of 38.4Kb or 57.6Kb. 14.4Kb time slots are only available on GSM networks that operate at 1,800MHz. 900Mhz GSM networks are limited to 9.6Kb time slots. Therefore, HSCSD is limited to 38.4Kbps on 900Mhz GSM networks. HSCSD can nly achieve 57.6Kbps on 1,800Mhz GSM networks.

This is a high speed, multi-slot data communications platform for GSM network.

HSCSD is the final evolution of circuit-switched data within the GSM environment. HSCSD will allow data speeds of up to 57.6kpbs, which is comparable to an ISDN B-line. Unlike GPRS, HSCSD establishes a dedicated connection between the parties exchanging data. As it is circuit-switched, it is more suited to applications such as video-conferencing and multi-media, rather than 'burst' type applications such as e-mail, which is more suited to packet-based services.

high-speed circuit-switched data. HSCSD allows wireless data to be sent at a rate of 38.4Kbps (kilobits per second) or more, as opposed to a current GSM speed of 9.6Kbps. This is comparable to the transmission rates of usual modems via fixed telephone networks today.

High Speed Circuit Switched Data. The most important feature of this technology is the increased speed. This makes connection times shorter and the use of current applications more convenient and faster. Data connections can be up to four times faster than earlier, which means that applications such as mobile navigation services using maps and graphics become more attractive. As HSCSD is 'circuit switched', it is more suited to applications such as video conferencing and multimedia than applications that send data in bursts such as e-mail. HSCSD allows wireless data to be transmitted at 43.2 kilobits per second over GSM networks. This is comparable to the transmission rates of usual modems via fixed telephone networks today.

High Speed Circuit Switched Data: dedicated circuit-switched data communications technology for GSM which boosts data throughput up to 14.4 Kbps in a single channel, and by aggregating channels, up to 57.6 Kbps. An asymmetrical service can be offered where, for instance, one channel is allocated for the uplink and several are aggregated for the downlink. HSCSD can provide a fixed bit rate (transparent mode) or a variable one (non-transparent mode). In most cases HSCSD is available to network operators as a pure software upgrade. HSCSD started to appear in some networks in 1999.

Short for High Speed Circuit Switched Data, HSCSD is an enhancement of CSD services of all current GSM networks. Access to data services is 3 times faster at a speed of up to 28.8 kbps. In many networks upgrades will mean that rates of up to 43.2 kbps are achievable meaning faster transmission of MMS and email and quicker access to other online services. HSCSD uses multiple channels to reach these higher data transfer rates.

High Speed Circuit Switched Data is a data transmission technology for mobile communication networks. It is based on the same principle as an ISDN line, i.e. a number of communication channels are bundled together to create a high-performance data transmission channel enabling speeds of up to 57.6 kbps (close to the ISDN standard). more...

High Speed Circuit Switched Data. In the user's point of view the most important feature is the increased speed. This makes connection times shorter and the use of current applications more convenient and faster. Data connections can be up to four times faster than earlier and the use of such applications as mobile navigation services using maps and graphics comes more attractive. As HSCSD is circuit switched, it is more suited to applications such as videoconferencing and multimedia than 'bursty' type applications such as email, which is more suited to packet switched data (GPRS). HSCSD allows wireless data to be transmitted at 43.2 kilobits per second over GSM networks. This is comparable to the transmission rates of usual modems via fixed telephone networks today.

High Speed Circuit Switched Data is an alternative to GPRS. Several GSM timeslots are added together to reach higher transfer rates up to 38,4 Kbps. That does only work, however, if the network has sufficient free capacity. A permanent connection is established for which the user is charged. HSCSD is more suited to video-conferencing and multimedia than for standard applications such as e-mail. It is mainly deployed in Scandinavia, the UK and Hong Kong. In Germany, only D2 and E-Plus offer HSCSD.

Basic GSM supports one voice or 9.6 kbps data (circuit switched data or CSD) call over just one of the eight time slots per 200kHz GSM radio channel. Practically, the system is limited to four time slots per device in each direction, but this still provides a transmission speed up to 38.4kbps over circuit switched GSM.
