	Welcome to GSM \|\| GSM Services
		GSM is able to provide clients throughout the world, onshore and offshore, with the expertise to organize, develop, and execute projects ranging in size from a single well to an entire field.
		GSM is a pioneer in the arena of high-angle (horizontal) drilling.
		GSM has the capacity to provide the client with reliable information at the inception of drilling and completion projects, including project feasibility and an economic study, geological evaluations of the project area, administration and selection of services through competitive bidding, preparation of project AFE cost estimate, evaluation and acquisition of equipment and project scheduling.

	GSM services - Wikipedia, the free encyclopedia
		GSM services are a standard collection of applications and features available to mobile phone subscribers all over the world.
		The systems that monitor and provide the prepaid services are not part of the GSM standard services, but instead an example of intelligent network services that a mobile phone operator may decide to implement in addition to the standard GSM ones.
		During a GSM call, speech is converted from analogue sound waves to digital data by the phone itself, and transmitted through the mobile phone network by digital means.

	Global System for Mobile Communications - Wikipedia, the free encyclopedia
		GSM differs significantly from its predecessors in that both signaling and speech channels are digital, which means that it is considered a second generation (2G) mobile phone system.
		As the GSM standard continued to develop, it retained backward compatibility with the original GSM phones; for example, packet data capabilities were added in the Release '97 version of the standard, by means of GPRS.
		GSM is a cellular network, which means that mobile phones connect to it by searching for cells in the immediate vicinity.

	About Global System for Mobile Communications (GSM)
		GSM then will accommodate for almost 60% of the global cellular subscriber base with yearly shipments in excess of 100 million phones.
		GSM has been defined as a platform, which is adaptable to a variety of new market requirements.
		During the definition of the GSM standard the rate of progress was too slow and didn't match with the pace of the market that required a new cellular standard.

	GSM services \| Topic Definition \| Find the Meaning and Define the Answer of GSM services
		The design of the service is moderately complex because it must be able to locate a moving phone anywhere in the world, and accomodate the relatively short battery life, limited input/output capabilities, and weak radio transmitters on mobile devices.
		Once a mobile phone has successfully attached to a GSM network as described above, calls may be made from the phone to any other phone on the global Public Switched Telephone Network assuming the subscriber an arrangement with their "home" phone company to allow the call.
		Many mobile service operators use their SMSCs as gateways to external systems, including the Internet, incoming SMS news feeds, and each other (often using the defacto SMPP standard).

	USS Clueless - GSM 3G
		GSM also included a very powerful set of features above that, and included some interesting features not directly associated with the RF link, such as a personality module which contained a customer's phone number and billing information that could be moved to another phone any time the customer wished to.
		GSM was clearly superior to IS-136 or such abortions as IDEN (a Motorola design which never became an industry standard because Moto was never willing to license it, which meant that systems which adopted it could only get infrastructure and handsets from Motorola).
		GSM has many features which are marvelous, but they can eventually be grafted onto IS-95 and CDMA2K, because they're all implemented at high protocol levels or don't have anything to do with the RF link.

		GSM retained backward-compatibility with the original GSM phones as the GSM standard continued to develop, for example packet data capabilities were added in the Release ´97 version of the standard, by means of GPRS.
		Roaming with GSM phones is a major advantage over the competing technology as roaming across CDMA networks from different operators can be difficult or impossible, if the operators lack a roaming agreement or work on different frequency bands.
		GSM also uses various satellites to redirect the voice and data packets to users across different countries, because it would be virtually impossible to connect instantly to a GSM phone located in parts of the world where they don´t have a high speed wired network.

		To add insult to penury, the long-awaited UMTS services will take some time to become dominant, which means that, for several years to come, operators will continue to be reliant both on less efficient networks and on the voice services that users increasingly view as a commodity.
		Mobile telephony started out as a service to business people who were expected to pay extra for the kudos and convenience, and did.
		However, as mobile operators have tapped into an ever-larger proportion of the population and mobile begins to displace fixed, ARPUs have, at least as a function of the amount paid per minute, inexorably, declined.
