What is HSCSD (High Speed Circuit Switched Data)?

High Speed Circuit Switched Data is an upgrade in the information rate of circuit switched information in a GSM network. A transfer rate of up to 57.6 kbit/s can be reached, or 115 kbit/s if a network permits consolidating 8 slots rather than only 4. The principal advantage of HSCSD contrasted with different information upgrades presented later is that it is an inexpensive method to implement higher data rates in GSM networks.
