	Global System for Mobile Communications - Biocrawler (Site not responding. Last check: 2007-10-18)
		The Global System for Mobile Communications (GSM) is the most popular standard for mobile phones in the world.
		The name of the system comes from the name of this group, though later the decision was made to keep the initials but to change what they stood for.
		GSM is a cellular network, which means that mobile phones connect to it by searching for cells in the immediate vicinity.

	Global system for mobile communications
		The Global System for Mobile communications (GSM), formerly known as "Groupe Spécial Mobile" (French), is a world-wide standard for digital wireless mobile phones.
		The standard was originated by CEPT and further developed by ETSI as a standard for European mobile phones, with the intention of developing a standard for adoption world-wide.
		In Europe and other areas outside North America the GSM system initially used a frequency of 900MHz, shortly afterwards the PCN network used the 1800MHz frequency, nowadays the PCN networks are considered part of the GSM system and many phones are dual-band operating on 900/1800MHz.

		The location of the mobile is typically in the form of the signalling address of the VLR associated with the mobile station.
		When a mobile station is switched on in a new location area, or it moves to a new location area or different operator's PLMN, it must register with the network to indicate its current location.
		The GSM system, and its sibling systems operating at 1.8 GHz (called DCS1800) and 1.9 GHz (called GSM1900 or PCS1900, and operating in North America), are a first approach at a true personal communication system.

	About Global System for Mobile Communications (GSM)
		The pressure for a unified and enhanced cellular system formed the basis for the definition of the GSM standard.
		Digital technology was chosen to leverage from the system integration capabilities of the semiconductor industry to enable smaller, lower power consuming and lower cost hand-portables.
		This could have had serious implications for the global spread of GSM by limiting the number of countries to which it could be sold.

		Before the Global System for Mobile Communications (GSM) was developed, the countries of Europe used a number of incompatible first-generation cellular phone technologies.
		Second-generation systems such as GSM are based on the first-generation systems and share many characteristics.
		Two virtually identical systems, DCS-1800 and DCS-1900, are based on GSM and differ mainly in using spectral allocations at 1800 and 1900 MHz, respectively.

	Global System for Mobile Communications (GSM)
		Initially developed to support a standardized approach to digital cellular communications in Europe, the "Global System for Mobile Communications" (GSM) protocols are rapidly being adopted to the next generation of wireless telecommunications systems, Personal Communication Systems (PCS) and global Low Earth Orbit (LEO) satellite communication systems.
		Finally, the communication management layer includes services to handle short message services, that are more efficiently handled through packet oriented transfers than the traditional circuit switched connections supported by the mainstream GSM system.
		By providing a standard for wireless communication that has been accepted in many areas of the world, users benefit from the ability to be reached regardless of their location.

	What is GSM? Global System for Mobile Communications Network
		GSM stands for Global System for Mobile Communications, which is basically the mobile phone network as we know it.
		For remote monitoring systems it means that wire free systems can easily be fitted in all corners of the globe, mobile applications can be easily accommodated and the instrument can be moved from one piece of equipment to another with the minimum of fuss.
		GSM is one of the leading digital mobile telephone system in the world and belongs to the technology of the second generation or so-called 2G.

		GSM (Global System for Mobile Communications) is a European digital communications standard which provides full duplex data traffic to any device fitted with GSM capability, such as a phone, fax, or pager, at a rate of 9600 bps using the TDMA communications scheme.
		Since GSM is purely digital, it can easily interface with other digital communications systems, such as ISDN, and digital devices, such as Group 3 facsimile machines.
		While each system uses the GSM standard, they are not compatible with each other.

		Global System for Mobile Communications (GSM) is the grandfather of most 3G mobile network environments.
		GSM's success was not so much dependent on the architectural definnitions that it put together for public land mobile networks (PLMNs).
		For a description of the interfaces, architecture and system design, I highly recommend Gunnar Heine's excellent book GSM Networks: Protocols, Terminology, and Implementation.

	Global System for Mobile Communications - Wikipedia, the free encyclopedia
		The Global System for Mobile Communications, GSM (original acronym: Groupe Spécial Mobile) is the most popular standard for mobile phones in the world.
		When these audio devices are in the near field of the GSM handset, the radio signal is strong enough that the solid state amplifiers in the audio chain function as a detector.
		This is a form of RFI, and could be mitigated or eliminated by use of additional shielding and/or bypass capacitors in these audio devices, however, the increased cost of doing so is difficult for a designer to justify.

	The Global System for Mobile Communications Short Message Service
		In cell broadcast, a message is transmitted to all the active handsets or mobile stations (MSs) present in a cell that have the capability of receiving short messages and have subscribed to this particular information service.
		Digital communications system (DCS) networks working at 1800 MHz need twice the number of BTSs to cover the same area as GSM networks, but provide twice the capacity.
		The current location of an MS is in the form of a Mobile Station Roaming Number (MSRN), typically the SS7 number of the visited MSC, and used to route a call to the MSC where the mobile is actually located.

	Definition: GSM (Global System for Mobile Communications) [Web and XML Glossary]
		It was developed in order to create a common european mobile telephone standard but it has been rapidly accepted worldwide.
		The disadvantage of this design is the focus on circuit-switched technologies, which currently makes GSM less than ideally suited for mobile data access.

	Howstuffworks "What does GSM mean in a cell phone?"
		Probably the most useful thing to know about the Global System for Mobile communications (GSM) is that it is an international standard.
		Originally, the acronym GSM stood for Groupe Spécial Mobile, a group formed by the Conference of European Posts and Telegraphs (CEPT) in 1982 to research the merits of a European standard for mobile telecommunications.
		Think of GSM and IS-136 as two different operating systems that work on the same processor, like Windows and Linux both working on an Intel Pentium III.

		This was an undesirable situation, because not only was the mobile equipment limited to operation within national boundaries, which in a unified Europe were increasingly unimportant, but there was a very limited market for each type of equipment, so economies of scale, and the subsequent savings, could not be realized.
		The VLR then converts the roaming number to the mobile's TMSI, and a paging call is broadcast by the cells under the control of the current BSC to inform the mobile.
		Both the mobile and the AC then use the random number, in conjuction with the subscriber's secret key and a ciphering algorithm called A3, to generate a number that is sent back to the AC.

		GSM is a cellular network, which means that mobile phones connect to it by seaching for cells in the immediate vicinity.
		However, this is not a pre-requisite, since indoor coverage is also provided by in-building penetration of the radio signal.
