	High-Speed Circuit-Switched Data - Wikipedia, the free encyclopedia
		HSCSD provides several levels of possible error correction which can be deployed according to the quality of the radio link.
		HSCSD require the time slots being used to be fully reserved for a single user.
		Apart from the fact that the full allocated bandwidth of the connection is available for the HSCSD user, HSCSD also has an advantage in GSM systems in terms of lower average radio interface latency than GPRS.

	Stepping Up to HSCSD
		HSCSD now is being deployed worldwide by carriers that need to provide their customers with high-bandwidth services.
		HSCSD provides circuit-switched connections, where transmission resources (up to four time slots) are dedicated to the user for the duration of the call.
		HSCSD still is a viable technology for those carriers needing to implement premi um video services today or not planning to move to 3G in the near term.

	HSCSD - High Speed Circuit Switched Data: HSCSD - High Speed Circuit Switched Data
		HSCSD is currently available to 90 millions subscribers across 25 countries around the world and with the implementation of International Roaming agreements between all HSCSD Operators life on the move just got easier.
		HSCSD is offered to subscribers using either voice terminals that support the feature, or a special PCMCIA portable computer card, with a built in GSM phone that turns notebook computers and other portable devices into a complete high-speed mobile office with the ability to make voice calls hands free, as well as data transfer.
		The HSCSD service is particularly valuable for customers who wish to access the Internet, or their office Intranet, access their mail, or access files stored elsewhere.

		HSCSD can be symmetrical or asymmetrical - you can use two downlink and one uplink timeslot to give 28k8 downloads but 14k4 uploads.
		HSCSD handsets typically are able to use a certain number of timeslots - for example 4 on the Nokia 6210 and Card Phone II.
		Whilst HSCSD may allow you to use 14k4 rather than 9k6 on each timeslot, if the radio signal is poor the network may force you to use 9k6.

		HSCSD is intended for the user who wants dedicated bandwidth; for example, for immediate file transfer, while GPRS will suit those users who don't require such time-critical services.
		HSCSD technology, which was fully approved by ETSI (European Telecommunications Standards Institute) in 1997, employs a proven channel-coding scheme that increases the channel bit rate from the existing 9.6kbps to 14.4kbps.
		HSCSD also allows the combining of channels to enable data rates in multiples of 9.6kbps or 14.4kbps.

		A HSCSD connection is to be set up between a switching device (MSC/MGW) and a mobile station (MS) where the MS communicates over the air interface with a BTS (controlled by a BSC via an Abis-interface) of the base station subsystem BSS of a cellular mobile telecommunication network.
		Change of HSCSD configuration: As depicted in Figure 3, the new configuration is signalled to the IWF using the appropriate RFCI value, which is sent together with each data packet.
		Method for initiating a HSCSD call set-up in a cellular mobile telecommunication system, wherein a RAB Assignment message is sent between a switching device (3G-MSC or MGW) to a base station controller (GERAN- BSC) containing a description of allowed multislot configurations for the HSCSD call which is to be initiated.

	Wireless Developer Network - Mobile Wireless Tomorrow
		HSCSD (High speed circuit swiched data) is the evolution of circuit switched data within the GSM environment.
		HSCSD is therefore more likely to be deployed in start up networks or those with plenty of spare capacity since it is relatively inexpensive to deploy and can turn some spare channels into revenue streams.
		HSCSD may be used by operators with enough capacity to offer it at lower prices, such as Orange.

	What is HSCSD
		HSCSD [High Speed Circuit Switched Data] falls under the general category of 2.5G technologies and it provides high speed data for GSM based networks.
		It is technically feasible to combine up to four slots but most users will configure their handsets set to three slots receiving data and just one slot sending data back to the network.
		Whichever approach is adopted, HSCSD is currently still faster than GPRS that struggles to provide users with higher than 20 Kbit/s connections.

	Gprs and Edge to 3G
		In theory, HSCSD can be preempted by voice calls- such that HSCSD calls can be reduced to one channel if voice calls are seeking to occupy these channels.
		HSCSD is therefore more likely to be deployed in start up networks or those with plenty of spare capacity- since it is relatively inexpensive to deploy and can turn some spare channels into revenue streams.
		Another preferred application for HSCSD could be the fact that whilst GPRS is complementary for communicating with other packet-based networks such as the Internet, HSCSD could be the best way of communicating with other circuit switched communications media such as the PSTN and ISDN.

	Interview: Kang Aik Siang of SingTel Mobile
		The ball is in the court of the suppliers of the terminals - how fast they can roll these out commercially and set a price that is going to be affordable to the market.
		HSCSD is suitable for applications and features which require huge amount of data to be transmitted like file transfer and like video conferencing, which is something that GPRS might not be able to support.
		Based on the specifications, the terminals are able to support both, so the customer might be able to use one application on GPRS and another application on HSCSD, so that they can achieve the best of both worlds.

	HSCSD by the millions - infoSync World
		Now, HSCSD is available to more than 100 million customers across 27 countries around the world - in Europe, Asia Pacific, South Africa and Israel, and in many cases international roaming is also possible.
		A major question for consumers and corporate users alike has been whether HSCSD will be replaced by the increasingly popular GPRS packet-based transfer technology, but for the time being it seems as though both technologies will be able to co-exist peacefully, at least for some time ahead.
		It is however likely that GPRS will replace HSCSD as a part of the progression towards packet-based 3G networks, but how quickly the transition will take place depends on how soon operators can offer competitively priced GPRS services and an acceptable penetration of international roaming services.

		High Speed Circuit Switched Data (HSCSD) is a new circuit switched data bearer (CSD) that offers considerably higher throughput than is currently available with CSD.
		HSCSD is similar to CSD in that a subscriber is allocated a single core time slot for the duration of the call.
		However, using HSCSD the MTN network can also allocate the subscriber up to three additional timeslots as they become available on the network.

	Orange beats rivals to high-speed mobile data - Printer friendly - ZDNet UK News (Site not responding. Last check: 2007-10-08)
		HSCSD will provide data transfer rates of 28.8kbit/s over the Orange network, while its competitors remain stuck with GSM's measly 9.6kbit/s until General Packet Radio System (GPRS) arrives.
		HSCSD works by grabbing two data channels and compressing them, using proprietary technology developed by Orange and Strathclyde University.
		Cherril suggests a main reason why HSCSD appears a relative unknown compared to GPRS "is because Vodafone, One to One and Cellnet don't have the network capacity to roll out a high-speed network, which is really down to historical factors.

		With HSCSD (High Speed Circuit Switched Data) operators can for the first time offer consumers rapid delivery of large amounts of data over GSM networks.
		We're providing an advanced platform that also enables operators to attract new customer segments." HSCSD is especially well suited for time sensitive, real-time services such as transferring large data files, video-based services, including traffic surveillance, e-mail and wireless access to the corporate intranet or Internet.
		Another key feature of the Ericsson HSCSD implementation is that it by default defines voice calls (as single time slot calls) to have a higher priority than data connections (as multiple time slot calls).
