99-703: The network claims to have been the first GSM -based mobile operator in South Asia. Formerly known as Mobilink, the company was founded in 1994 as a joint venture between Saif Group and Motorola Inc. In February 2001, Egypt based Orascom Telecom Holding bought Motorola’s shares in Mobilink to become the majority shareholder with 69% control. Then in June 2007, Orascom further purchased the remaining shares under Saif Group’s control to become Mobilink’s 100% owner. In 2010, Russian operator Vimpelcom (now VEON Ltd.) agreed to acquire most of

198-478: A PHP wiki engine with a MySQL database; this software was custom-made for Misplaced Pages by Magnus Manske . The Phase II software was repeatedly modified to accommodate the exponentially increasing demand. In July 2002 (Phase III), Misplaced Pages shifted to the third-generation software, MediaWiki, originally written by Lee Daniel Crocker . Some MediaWiki extensions are installed to extend the functionality of MediaWiki software. In April 2005, an Apache Lucene extension

297-402: A telecommunications service provider 's network via 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

396-597: A transclusion system for templates , and URL redirection . MediaWiki is licensed under the GNU General Public License and it is used by all Wikimedia projects. Originally, Misplaced Pages ran on UseModWiki written in Perl by Clifford Adams (Phase I), which initially required CamelCase for article hyperlinks; the double bracket style was incorporated later. Starting in January 2002 (Phase II), Misplaced Pages began running on

495-524: A "Knowledge Equity Fund", to provide grants to organizations whose work would not otherwise be covered by Wikimedia grants but addresses racial inequities in accessing and contributing to free knowledge resources. In January 2016, the Foundation announced the creation of an endowment to safeguard its future. The Wikimedia Endowment was established as a donor-advised fund at the Tides Foundation , with

594-645: A caching cluster in an Equinix facility in Singapore , the first of its kind in Asia. The operation of Wikimedia depends on MediaWiki , a custom-made, free and open-source wiki software platform written in PHP and built upon the MariaDB database since 2013; previously the MySQL database was used. The software incorporates programming features such as a macro language , variables ,

693-441: 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, the 3GPP developed third-generation ( 3G ) UMTS standards, followed by the fourth-generation ( 4G ) LTE Advanced and

792-470: A feeder project to supplement Nupedia . The project was originally funded by Bomis , Wales's for-profit business, and edited by a rapidly growing community of volunteer editors. The early community discussed a variety of ways to support the ongoing costs of upkeep, and was broadly opposed to running ads on the site, so the idea of setting up a charitable foundation gained prominence. That addressed an open question of what entity should hold onto trademarks for

891-552: A former Nokia engineer Pekka Lonka revealed to Helsingin Sanomat making a test call just a couple of hours earlier. "World's first GSM call was actually made by me. I called Marjo Jousinen, in Salo.", Lonka informed. The following year saw the sending of the first short messaging service (SMS or "text message") message, and Vodafone UK and Telecom Finland signed the first international roaming agreement. Work began in 1991 to expand

990-526: A grant agreement was reached with the John S. and James L. Knight Foundation to build a search engine called the " Knowledge Engine ", a project that proved controversial . In 2017, the Sloan Foundation awarded another $ 3 million grant for a three-year period, and Google donated another $ 1.1 million to the Foundation in 2019. The following have donated $ 500,000 or more each (2008–2019, not including gifts to

1089-562: A joint development agreement in 1984 and were joined by Italy and the UK in 1986. In 1986, the European Commission proposed reserving the 900 MHz spectrum band for GSM. It was long believed that the former Finnish prime minister Harri Holkeri made the world's first GSM call on 1 July 1991, calling Kaarina Suonio (deputy mayor of the city of Tampere ) using a network built by Nokia and Siemens and operated by Radiolinja . In 2021

1188-577: 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 the four big EU countries cemented their political support for GSM with the Bonn Declaration on Global Information Networks in May and

1287-571: A more easily consumable way, the data of the Wikimedia projects, including Misplaced Pages . It allows customers to retrieve data at large scale and high availability through different formats like Web APIs , data snapshots or streams . It was announced in March 2021, and launched on October 26, 2021. Google and the Internet Archive were its first customers, although Internet Archive is not paying for

1386-620: A move as letting down those who elected me." He subsequently added that while on the Board, he had pushed for greater transparency regarding the Wikimedia Foundation's Knowledge Engine project and its financing, and indicated that his attempts to make public the Knight Foundation grant for the engine had been a factor in his dismissal. Heilman was reelected to the board by the community in 2017. In January 2016, Arnnon Geshuri joined

1485-539: A number of countries in Africa and the Middle East. List of people in board of directors to whom Mobilink is governed. The Mobilink Foundation is a registered non-profit organization, which provides support for the local community not only financially but also through dedicated volunteer hours. Being a philanthropic organization, it is purely based on employee volunteerism. No administrative costs or overheads are incurred age

1584-456: 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

1683-527: 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

1782-772: A single server until 2004, when the server setup was expanded into a distributed multitier architecture . Server downtime in 2003 led to the first fundraising drive. By December 2009, Wikimedia ran on co-located servers, with 300 servers in Florida and 44 in Amsterdam . In 2008, it also switched from multiple different Linux operating system vendors to Ubuntu Linux . In 2019, it switched to Debian . By January 2013, Wikimedia transitioned to newer infrastructure in an Equinix facility in Ashburn, Virginia , citing reasons of "more reliable connectivity" and "fewer hurricanes ". In years prior,

1881-681: A stated goal to raise $ 100 million in the next 10 years. Craig Newmark was one of the initial donors, giving $ 1 million. Peter Baldwin and Lisbet Rausing , of Arcadia Fund , donated $ 5 million in 2017. In 2018, major donations to the endowment were received from Amazon and Facebook ($ 1 million each) and George Soros ($ 2 million). In 2019, donations included $ 2 million from Google, $ 3.5 million more from Baldwin and Rausing, $ 2.5 million more from Newmark, and another $ 1 million from Amazon in October 2019 and again in September 2020. As of 2023,

1980-478: 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

2079-443: A term referring to inexperienced individuals utilizing readily available hardware and software. The vulnerability arises from the accessibility of tools such as a DVB-T TV tuner, posing a threat to both mobile and network users. Despite the term "script kiddies" implying a lack of sophisticated skills, the consequences of their attacks on GSM can be severe, impacting the functionality of cellular networks . Given that GSM continues to be

2178-536: A trustee recently elected to the board by the community, was removed from his position by a vote of the rest of the board. This decision generated dispute among members of the Misplaced Pages community. Heilman later said that he "was given the option of resigning [by the Board] over the last few weeks. As a community elected member I see my mandate as coming from the community which elected me and thus declined to do so. I saw such

2277-444: 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

2376-645: Is B60 ( Adult , Continuing education ). The Foundation filed an application to trademark the name Misplaced Pages in the US to the Board of Patent Appeals and Interferences on September 14, 2004. The mark was granted registration status on January 10, 2006. Trademark protection was accorded also by Japan on December 16, 2004, and by the European Union on January 20, 2005. Subsets of Misplaced Pages were already being distributed in book and DVD form, and there were discussions about licensing

2475-629: Is also a trade mark owned by the GSM Association . " GSM " may also refer to the voice codec initially used in GSM. 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

2574-499: Is also available with no photos on Mobilink. Mobilink previously announced its merger with Warid Tel in November 2015. The case was under review at Pakistan telecommunication authority . After scrutiny PTA finally approved the merger on 24 May 2016. In January 2017, Mobilink CEO, Aamir Ibrahim, stated that the Warid brand name would be history, and both companies would be re-launched under

2673-426: Is called SIM locking and 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

2772-443: 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

2871-496: Is organized by a committee supported usually by the local national chapter, with support from local institutions (such as a library or university) and usually from the Wikimedia Foundation. Wikimania has been held in cities such as Buenos Aires , Cambridge , Haifa , Hong Kong , Taipei , London , Mexico City , Esino Lario , Italy , Montreal , Cape Town , and Stockholm . The 2020 conference scheduled to take place in Bangkok

2970-486: 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

3069-507: 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

3168-551: The Charities Aid Foundation , scheduled to be funded in five equal installments from 2012 through 2015. In 2014, the Foundation received the largest single gift in its history, a $ 5 million unrestricted donation from an anonymous donor supporting $ 1 million worth of expenses annually for the next five years. In March 2012, The Gordon and Betty Moore Foundation , established by the Intel co-founder and his wife, awarded

3267-665: 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 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

3366-541: The Northern Territory had earlier in the year been shut down in April 2017. Singapore shut down 2G services entirely in April 2017. The network 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

3465-554: The San Francisco Bay Area . Considerations cited for choosing San Francisco were proximity to like-minded organizations and potential partners, a better talent pool, as well as cheaper and more convenient international travel. The move was completed by January 31, 2008, into a headquarters on Stillman Street in San Francisco. It later moved to New Montgomery Street, and then to One Montgomery Tower . On October 25, 2021,

GSM 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

3762-591: The 3G Universal Mobile Telecommunications System (UMTS), code-division multiple access (CDMA) technology, nor the 4G LTE orthogonal frequency-division multiple access (OFDMA) technology standards issued by 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

3861-682: The 900 MHz or 1800 MHz bands. Where these bands were already allocated, 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

3960-511: The Foundation announced what was then its largest donation yet: a three-year, $ 3 million grant from the Sloan Foundation . In 2009, the Foundation received four grants. The first was a $ 890,000 Stanton Foundation grant to help study and simplify the user interface for first-time authors of Misplaced Pages. The second was a $ 300,000 Ford Foundation grant in July 2009 for Wikimedia Commons , to improve

These do not include funds in

4554-553: The GSM MoU was tabled for signature in September. The MoU drew in mobile operators from across Europe to pledge to invest in new GSM networks to an ambitious common date. In this short 38-week period the whole of Europe (countries and industries) had been brought behind GSM in 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

4653-470: The GSM specification supports in practical use is 35 kilometres (22 mi). There are also several implementations of the concept of an extended cell, where the cell radius could be double or even more, depending on the antenna system, the type of terrain, and the timing advance . GSM supports indoor coverage – achievable by using an indoor picocell base station, or an indoor repeater with distributed indoor antennas fed through power splitters – to deliver

4752-516: The GSM standard served 80% of the mobile market, encompassing more than 5 billion people across more than 212 countries and territories, making GSM the most ubiquitous of the many standards for cellular networks.

6930-614: The key features of GSM is the Subscriber Identity Module , commonly known as a SIM card . The SIM 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

7029-596: The local market. Telstra in Australia shut down its 2G GSM network on 1 December 2016, the first mobile network operator to decommission a GSM network.

The bylaws were accordingly amended to remove all references to membership rights and activities. In 2007, the Foundation decided to move its headquarters from Florida to

7227-414: The main source of cellular technology in numerous countries, its susceptibility to potential threats from malicious attacks 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

7326-483: The merger was completed in July 2016 and the companies were going to plan for integration and merging into a single brand in the future. In November 2016, Mobilink announced that Warid customers would be able to use their 3G network, and Mobilink customers will be able to use Warid's LTE network. Mobilink is a communications access provider offering customers access through different channels. The four key platforms Mobilink operates are: Mobilink (PMCL) acquired and merged

7425-466: The open-source version. As of 2011 , there have been no lawsuits against users of OpenBTS over GSM use. Wikimedia Foundation The Wikimedia Foundation, Inc. , abbreviated WMF , is an American 501(c)(3) nonprofit organization headquartered in San Francisco , California , and registered there as a charitable foundation . It is the host of Misplaced Pages , the seventh most visited website in

7524-485: The organization and therefore, every single penny that is donated to Mobilink Foundation goes directly into making a difference on the ground. The Mobilink Foundation Torchbearers clock an average of 4 to 5 dedicated hours per person per month during official working hours.

Campaigns for the Wikimedia Endowment have included emails asking donors to leave Wikimedia money in their will. As a 501(c)(3) charity, the Foundation is exempt from federal and state income tax. It is not a private foundation, and contributions to it qualify as tax-deductible charitable contributions. In 2007, 2008 and 2009, Charity Navigator gave Wikimedia an overall rating of four out of four possible stars, increased from three to four stars in 2010. As of January 2020 ,

7920-552: The radio signals from an antenna outdoors to the separate indoor distributed antenna system. Picocells are typically deployed when significant call capacity 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

8019-497: The rating was still four stars (overall score 98.14 out of 100), based on data from FY2018. The Foundation also increases its revenue through federal grants , sponsorship, services and brand merchandising. The Wikimedia OAI-PMH update feed service, targeted primarily at search engines and similar bulk analysis and republishing, was a source of revenue for a number of years. DBpedia was given access to this feed free of charge. An expanded version of data feeds and content services

8514-458: 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 the development of UMTS , EFR was refactored into a variable-rate codec called AMR-Narrowband , which is high quality and robust against interference when used on full-rate channels, or less robust but still relatively high quality when used in good radio conditions on half-rate channel. One of

8613-1112: The technical and organizational infrastructure to enable members of the public to develop wiki-based content in languages across the world. The Foundation does not write or curate any of the content on the projects themselves. Instead, this is done by volunteer editors, such as the Wikipedians . However, it does collaborate with a network of individual volunteers and affiliated organizations, such as Wikimedia chapters, thematic organizations, user groups and other partners. The Foundation finances itself mainly through millions of small donations from readers and editors, collected through email campaigns and annual fundraising banners placed on Misplaced Pages and its sister projects. These are complemented by grants from philanthropic organizations and tech companies, and starting in 2022, by services income from Wikimedia Enterprise . As of 2023, it has employed over 700 staff and contractors, with net assets of $ 255 million and an endowment which has surpassed $ 100 million.

Completed in July 2016 after due approvals, the first-ever local telecom company acquisition created a combined subscriber base of 50 million. Following this merger, Mobilink

8811-400: 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 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

8910-415: 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 was developed first and is a stronger algorithm used within Europe and

9009-535: The web. The most commonly deployed GPRS ciphers were publicly broken in 2011. The researchers revealed flaws in the commonly used GEA/1 and GEA/2 (standing for GPRS Encryption Algorithms 1 and 2) ciphers and published the open-source "gprsdecode" software for sniffing GPRS networks. They also noted that some carriers do not encrypt the data (i.e., using GEA/0) in order to detect the use of traffic or protocols they do not like (e.g., Skype ), leaving customers unprotected. GEA/3 seems to remain relatively hard to break and

9108-411: The world. It also hosts fourteen related open collaboration projects, and supports the development of MediaWiki , the wiki software that underpins them all. The Foundation was established in 2003 in St. Petersburg, Florida by Jimmy Wales , as a non-profit way to fund these wiki projects. They had previously been hosted by Bomis , Wales's for-profit company. The Wikimedia Foundation provides
