What is HSCSD?
| High Speed Circuit Switched Data |
|
High Speed Circuit Switched Data GSM is currently a circuit switched technology and HSCSD is the final evolution of circuit switched data within the GSM environment. HSCSD will enable the transmission of data over a GSM link at speeds of up to 57.6 Kbps. This is achieved by concatenating, i.e. adding together, consecutive GSM time slots, each of which is capable of supporting 14.4 Kbps. Up to four GSM time slots are needed for the transmission of HSCSD. HSCSD is part of the planned evolution of the GSM specification and is included in the GSM Phase 2 development. In using it a permanent connection is established between the called and calling parties for the exchange of data. As it is circuit switched, HSCSD is more suited to applications such as video conferencing and multimedia than 'bursty' type applications such as e-mail, which is more suited to packet switched data -see GPRS. |
