The Global System for Mobile Communications ( GSM ) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation ( 2G ) digital cellular networks used by mobile devices such as mobile phones and tablets. GSM is also a trade mark owned by the GSM Association . " GSM " may also refer to the voice codec initially used in GSM.
117-777: It was first implemented in Finland in December 1991. By the mid-2010s, it became a global standard for mobile communications achieving over 90% market share, and operating in over 193 countries and territories. 2G networks developed as a replacement for first generation ( 1G ) analog cellular networks. The GSM standard originally described a digital, circuit-switched network optimized for full duplex voice telephony . This expanded over time to include data communications, first by circuit-switched transport , then by packet data transport via General Packet Radio Service (GPRS), and Enhanced Data Rates for GSM Evolution (EDGE). Subsequently,
234-518: A broadband-internet connection. Umbrella cells are used to cover shadowed regions of smaller cells and to fill in gaps in coverage between those cells. Cell horizontal radius varies – depending on antenna height, antenna gain , and propagation conditions – from a couple of hundred meters to several tens of kilometers. The longest distance the GSM specification supports in practical use is 35 kilometres (22 mi). There are also several implementations of
351-554: A memorandum of understanding in Copenhagen to develop and deploy a common cellular telephone system across Europe, and EU rules were passed to make GSM a mandatory standard. The decision to develop a continental standard eventually resulted in a unified, open, standard-based network which was larger than that in the United States. In February 1987 Europe produced the first agreed GSM Technical Specification. Ministers from
468-615: A presidential republic , with K. J. Ståhlberg elected as its first president on 25 July 1919. A liberal nationalist with a legal background, Ståhlberg anchored the state in liberal democracy , promoted the rule of law and initiated internal reforms. Finland was also one of the first European countries to strongly promote women's equality , with Miina Sillanpää becoming the first female minister in Finnish history in Väinö Tanner's cabinet in 1926–1927. The Finnish-Russian border
585-468: A diverse and extensive range of fauna. There are at least sixty native mammalian species, 248 breeding bird species, over 70 fish species, and 11 reptile and frog species present today, many migrating from neighbouring countries thousands of years ago. Large and widely recognized wildlife mammals found in Finland are the brown bear , grey wolf , wolverine , and elk . Three of the more striking birds are
702-664: A generic term for the plethora of G mobile phone technologies evolved from it. In 1983, work began to develop a European standard for digital cellular voice telecommunications when the European Conference of Postal and Telecommunications Administrations (CEPT) set up the Groupe Spécial Mobile (GSM) committee and later provided a permanent technical-support group based in Paris . Five years later, in 1987, 15 representatives from 13 European countries signed
819-426: A mast or a building above average rooftop level. Micro cells are cells whose antenna height is under average rooftop level; they are typically deployed in urban areas. Picocells are small cells whose coverage diameter is a few dozen meters; they are mainly used indoors. Femtocells are cells designed for use in residential or small-business environments and connect to a telecommunications service provider 's network via
936-533: A mutual security pact with the United Kingdom. On 12 May, Finland's president and Prime Minister called for NATO membership "without delay". Subsequently, on 17 May, the Finnish Parliament voted 188–8 in favour of Finland's accession to NATO. Finland became a member of NATO on 4 April 2023. Lying approximately between latitudes 60° and 70° N , and longitudes 20° and 32° E , Finland
1053-455: A problem for any open-source GSM implementation, because it is not possible for GNU or any other free software distributor to guarantee immunity from all lawsuits by the patent holders against the users. Furthermore, new features are being added to the standard all the time which means they have patent protection for a number of years. The original GSM implementations from 1991 may now be entirely free of patent encumbrances, however patent freedom
1170-654: A rare unity and speed guided by four public officials: Armin Silberhorn (Germany), Stephen Temple (UK), Philippe Dupuis (France), and Renzo Failli (Italy). In 1989 the Groupe Spécial Mobile committee was transferred from CEPT to the European Telecommunications Standards Institute (ETSI). The IEEE/RSE awarded to Thomas Haug and Philippe Dupuis the 2018 James Clerk Maxwell medal for their "leadership in
1287-476: A relationship between two parts of the algorithm. The researchers found that this relationship was very unlikely to have happened if it was not intentional. This may have been done in order to satisfy European controls on export of cryptographic programs. The GSM systems and services are described in a set of standards governed by ETSI , where a full list is maintained. Several open-source software projects exist that provide certain GSM features: Patents remain

#17327731197081404-486: A result of the two wars, Finland lost 12% of its land area, 20% of its industrial capacity, its second largest city, Vyborg ( Finnish : Viipuri ), and the ice-free port of Liinakhamari ( Finnish : Liinahamari ). The Finns lost 97,000 soldiers and were forced to pay war reparations of $ 300 million ($ 4.1 billion in 2023). However, the country avoided occupation by Soviet forces and managed to retain its independence. Along with Great Britain, Finland emerged from
1521-480: A stronger one. Since 2000, different efforts have been made in order to crack the A5 encryption algorithms. Both A5/1 and A5/2 algorithms have been broken, and their cryptanalysis has been revealed in the literature. As an example, Karsten Nohl developed a number of rainbow tables (static values which reduce the time needed to carry out an attack) and have found new sources for known plaintext attacks . He said that it
1638-418: A system based on linear predictive coding (LPC). In addition to being efficient with bitrates , these codecs also made it easier to identify more important parts of the audio, allowing the air interface layer to prioritize and better protect these parts of the signal. GSM was further enhanced in 1997 with the enhanced full rate (EFR) codec, a 12.2 kbit/s codec that uses a full-rate channel. Finally, with
1755-705: A violent time in the northern Baltic Sea. The Livonian Crusade was ongoing and the Finnish tribes such as the Tavastians and Karelians were in frequent conflicts with Novgorod and with each other. Also, during the 12th and 13th centuries several crusades from the Catholic realms of the Baltic Sea area were made against the Finnish tribes. Danes waged at least three crusades to Finland, in 1187 or slightly earlier, in 1191 and in 1202, and Swedes , possibly
1872-585: Is 4.615 ms. TDMA noise is interference that can be heard on speakers near a GSM phone using TDMA, audible as a buzzing sound. The transmission power in the handset is limited to a maximum of 2 watts in GSM 850/900 and 1 watt in GSM 1800/1900 . GSM has used a variety of voice codecs to squeeze 3.1 kHz audio into between 7 and 13 kbit/s. Originally, two codecs, named after the types of data channel they were allocated, were used, called Half Rate (6.5 kbit/s) and Full Rate (13 kbit/s). These used
1989-475: Is a detachable smart card containing a user's subscription information and phone book. This allows users to retain their information after switching handsets. Alternatively, users can change networks or network identities without switching handsets - simply by changing the SIM. Sometimes mobile network operators restrict handsets that they sell for exclusive use in their own network. This is called SIM locking and
2106-590: Is a member of various international organisations, such as the Nordic Council , the Schengen Area , and the Organisation for Economic Co-operation and Development (OECD). The nation performs extremely well in national performance metrics , including education , economic competitiveness, civil liberties, quality of life, and human development. The area that is now Finland was settled in, at
2223-454: Is implemented by a software feature of the phone. A subscriber may usually contact the provider to remove the lock for a fee, utilize private services to remove the lock, or use software and websites to unlock the handset themselves. It is possible to hack past a phone locked by a network operator. In some countries and regions (e.g. Brazil and Germany ) all phones are sold unlocked due to the abundance of dual-SIM handsets and operators. GSM
2340-477: Is needed indoors, as in shopping centers or airports. However, this is not a prerequisite, since indoor coverage is also provided by in-building penetration of radio signals from any nearby cell. GSM networks operate in a number of different carrier frequency ranges (separated into GSM frequency ranges for 2G and UMTS frequency bands for 3G), with most 2G GSM networks operating in the 900 MHz or 1800 MHz bands. Where these bands were already allocated,
2457-443: Is not certain due to the United States' "first to invent" system that was in place until 2012. The "first to invent" system, coupled with "patent term adjustment" can extend the life of a U.S. patent far beyond 20 years from its priority date. It is unclear at this time whether OpenBTS will be able to implement features of that initial specification without limit. As patents subsequently expire, however, those features can be added into

#17327731197082574-613: Is one of the world's northernmost countries. Of world capitals, only Reykjavík lies more to the north than Helsinki. The distance from the southernmost point – Hanko in Uusimaa – to the northernmost – Nuorgam in Lapland – is 1,160 kilometres (720 mi). Finland has about 168,000 lakes (of area larger than 500 m or 0.12 acres) and 179,000 islands. Its largest lake, Saimaa , is the fourth largest in Europe. The Finnish Lakeland
2691-633: Is one that needs to be addressed. The development of UMTS introduced an optional Universal Subscriber Identity Module (USIM), that uses a longer authentication key to give greater security, as well as mutually authenticating the network and the user, whereas GSM only authenticates the user to the network (and not vice versa). The security model therefore offers confidentiality and authentication, but limited authorization capabilities, and no non-repudiation . GSM uses several cryptographic algorithms for security. The A5/1 , A5/2 , and A5/3 stream ciphers are used for ensuring over-the-air voice privacy. A5/1
2808-484: Is possible to build "a full GSM interceptor ... from open-source components" but that they had not done so because of legal concerns. Nohl claimed that he was able to intercept voice and text conversations by impersonating another user to listen to voicemail , make calls, or send text messages using a seven-year-old Motorola cellphone and decryption software available for free online. GSM uses General Packet Radio Service (GPRS) for data transmissions like browsing
2925-511: Is said to be in use on some more modern networks. If used with USIM to prevent connections to fake base stations and downgrade attacks , users will be protected in the medium term, though migration to 128-bit GEA/4 is still recommended. The first public cryptanalysis of GEA/1 and GEA/2 (also written GEA-1 and GEA-2) was done in 2021. It concluded that although using a 64-bit key, the GEA-1 algorithm actually provides only 40 bits of security, due to

According to the WWF , the territory of Finland can be subdivided into three ecoregions : the Scandinavian and Russian taiga , Sarmatic mixed forests , and Scandinavian Montane Birch forest and grasslands . Taiga covers most of Finland from northern regions of southern provinces to
3159-400: Is structured into several discrete sections: GSM utilizes a cellular network , meaning that cell phones connect to it by searching for cells in the immediate vicinity. There are five different cell sizes in a GSM network: The coverage area of each cell varies according to the implementation environment. Macro cells can be regarded as cells where the base-station antenna is installed on

Even with the introduction of agriculture, hunting and fishing continued to be important parts of the subsistence economy. In the Bronze Age , permanent all-year-round cultivation and animal husbandry spread, but the cold climate slowed the change. The Seima-Turbino phenomenon brought
4095-617: The Declaration of Independence on 4 December 1917, which was officially approved by the Finnish Parliament on 6 December. The Russian Soviet Federative Socialist Republic (RSFSR), led by Vladimir Lenin was the first country to recognise Finland's independence on 4 January 1918. On 27 January 1918, the government began to disarm the Russian forces in Ostrobothnia . The socialists took control of southern Finland and Helsinki, but

Finland became the first territory in Europe to grant universal suffrage in 1906, and the first in the world to give all adult citizens the right to run for public office. Following the Russian Revolution of 1917, Finland declared its independence . A civil war was fought in Finland
4797-636: The Social Democratic Party . The development of trade with the Western powers, such as the United Kingdom, and the payment of reparations to the Soviet Union led to Finland's transformation from a primarily agrarian society to an industrialised one. Valmet , originally a shipyard and then several metal workshops, was established to produce materials for war reparations. After the reparations were paid, Finland continued to trade with

This allowed the country to experience overall prosperity and high per capita income . During the Cold War , Finland officially embraced a policy of neutrality. Since then, it has become a member of the European Union in 1995, the Eurozone in 1999, and NATO in 2023. Finland
5499-527: The 3GPP. GSM, for the first time, set a common standard for Europe for wireless networks. It was also adopted by many countries outside Europe. This allowed subscribers to use other GSM networks that have roaming agreements with each other. The common standard reduced research and development costs, since hardware and software could be sold with only minor adaptations for the local market. Telstra in Australia shut down its 2G GSM network on 1 December 2016,
5616-561: The 850 MHz and 1900 MHz bands were used instead (for example in Canada and the United States). In rare cases the 400 and 450 MHz frequency bands are assigned in some countries because they were previously used for first-generation systems. For comparison, most 3G networks in Europe operate in the 2100 MHz frequency band. For more information on worldwide GSM frequency usage, see GSM frequency bands . Regardless of

The dialects from which the modern-day Finnish language was developed came into existence during the Iron Age. Although distantly related, the Sami people retained the hunter-gatherer lifestyle longer than the Finns. The Sami cultural identity and the Sami language have survived in Lapland ,
5850-627: The Finns as the Greater Wrath (1714–1721) and the Lesser Wrath (1742–1743). It is estimated that almost an entire generation of young men was lost during the Great Wrath, due mainly to the destruction of homes and farms, and the burning of Helsinki. The Swedish era ended with the Finnish War of 1809. On 29 March 1809, after being conquered by the armies of Alexander I of Russia , Finland became an autonomous grand duchy within
5967-554: The Middle Ages, Finland gradually became part of the kingdom of Sweden and the sphere of influence of the Catholic Church . Under Sweden, Finland was annexed as part of the cultural order of Western Europe . Swedish was the dominant language of the nobility, administration, and education; Finnish was chiefly a language for the peasantry , clergy, and local courts in predominantly Finnish-speaking areas.

In 1950, 46% of Finnish workers were employed in agriculture and a third lived in urban areas, but new jobs in manufacturing, services and trade quickly attracted people to the cities. The average number of births per woman fell from a baby boom peak of 3.5 in 1947 to 1.5 in 1973. As the baby boomers entered the workforce, the economy failed to create jobs fast enough and hundreds of thousands emigrated to more industrialised Sweden, with emigration peaking in 1969 and 1970. Finland participated in trade liberalisation in

Imports included silk and other fabrics, jewelry, Ulfberht swords , and, in lesser extent, glass. Production of iron started approximately in 500 BC. At the end of the ninth century, indigenous artefact culture, especially weapons and women's jewelry, had more common local features than ever before. This has been interpreted to be expressing common Finnish identity. An early form of Finnic languages spread to
7722-435: The emblem of the Finnish Association for Nature Conservation. A third of Finland's land area originally consisted of moorland , about half of this area has been drained for cultivation over the past centuries. The main factor influencing Finland's climate is the country's geographical position between the 60th and 70th northern parallels in the Eurasian continent's coastal zone. In the Köppen climate classification ,
