HSCSD
HSCSD in unabbreviated terms is the High-speed circuit-switched data. It is the advanced generation for circuit-switched data. GSM mobile phone systems can make use of the HSCSD. The transmission rates occur with speeds of approximately 57.6 kilobits per second.
The presence of HSCSD is currently up to 25 countries with concentrations in Europe. It initially became popular during the early 21st century where the technology started to show up in European countries in year 2000.
HSCSD is a standard protocol that allows use of multiple time slots during data transmission all working at the same time. The technology was designed to accommodate larger transmission capacity. The more time slots are used, the faster the transmission rates become. Every slot carries a bandwidth between 9.6 to 14.4 kilobits per second. Four maximum slots can be used at the same time which reaches to as fast as 57.6 kilobits per second of total transmission rate for every transaction.
The standard, however, cannot be used for voice transmissions but only for data transfer applications. Voice transmissions always take greater priority than data transfers. This means that there will be times when the HSCSD connection would not work to its full potential during voice transmissions. The reason behind it is that more slots are used for the voice applications.
HSCSD protocols are better than other protocol types on GSM handsets because it carries reliable data transfers. Because it is circuit-switched, sensitive transfers like video streaming can best benefit from the HSCSD transmission standard.
During HSCSD transfers, there is lesser interference from external sources. This is an advantage over other protocols and permits voice and data sessions to maintain better quality.
When it comes to cost, however, other protocols are more efficient. GPRS and other protocols are more popular with companies because they are cost efficient to build and the services are maintained at lower costs.
