TADIG Code
TADIG code is a number uniquely identifying network operators in a GSM mobile network. The acronym TADIG expands to "''Transferred Account Data Interchange Group''". According to the GSM specification, the codes are used as "primary identifiers within file contents and file names" in multiple file formats defined by the GSMA. Network operators are required to register new codes and limit themselves to using code already registered with the GSMA. TADIG codes are generally used by bilateral agreement for the purposes of billing roaming telephone calls. Format A TADIG code is 5 characters long, consisting of # Three-character country code. This is usually the ISO 3166-1 alpha-3 code for terrestrial operators. Non-terrestrial operators have the first two characters as AA. Wi-Fi operators have the first two characters as WW. # Two-character operator/ company identifier Example TADIG code: CANGW (for Freedom Mobile, formerly WIND Mobile) TADIG code: SWE01 (for the Sweden1 bilater ...

Acronym
An acronym is a word or name formed from the initial components of a longer name or phrase. Acronyms are usually formed from the initial letters of words, as in ''NATO'' (''North Atlantic Treaty Organization''), but sometimes use syllables, as in ''Benelux'' (short for ''Belgium, the Netherlands, and Luxembourg''). They can also be a mixture, as in ''radar'' (''Radio Detection And Ranging''). Acronyms can be pronounced as words, like ''NASA'' and ''UNESCO''; as individual letters, like ''FBI'', ''TNT'', and ''ATM''; or as both letters and words, like '' JPEG'' (pronounced ') and ''IUPAC''. Some are not universally pronounced one way or the other and it depends on the speaker's preference or the context in which it is being used, such as '' SQL'' (either "sequel" or "ess-cue-el"). The broader sense of ''acronym''—the meaning of which includes terms pronounced as letters—is sometimes criticized, but it is the term's original meaning and is in common use. Dictionary and st ...

GSMA
The GSM Association (commonly referred to as 'the GSMA' or ''Global System for Mobile Communications'', originally ''Groupe Spécial Mobile'') is an industry organisation that represents the interests of mobile network operators worldwide. More than 750 mobile operators are full GSMA members and a further 400 companies in the broader mobile ecosystem are associate members. The GSMA represents its members via industry programmes, working groups and industry advocacy initiatives. History The GSMA was formed in 1995 as the 'GSM MoU Association' as a body to support and promote mobile operators using the GSM (Global System for Mobile communications) standard for cellular networks. It traces its history back to a memorandum of understanding signed in 1987 by 13 operators in 12 countries that committed to deploying GSM for mobile services. Membership and governance Full membership of the GSMA is open to licensed mobile operators using a GSM family technology. Approximately 750 su ...

Roaming
Roaming is a wireless telecommunication term typically used with mobile devices, such as mobile phones. It refers to a mobile phone being used outside the range of its native network and connecting to another available cell network. Technical definition In more technical terms, roaming refers to ''the ability for a cellular customer to automatically make and receive voice calls, send and receive data, or access other services, including home data services, when travelling outside the geographical coverage area of the home network, by means of using a visited network''. For example: should a subscriber travel beyond their cell phone company's transmitter range, their cell phone would automatically hop onto another phone company's service, if available. The process is supported by the Telecommunication processes of mobility management, authentication, authorization and accounting billing procedures (known as AAA or 'triple A'). Roaming in general Roaming is divided into "S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 3166-1 Alpha-3
ISO 3166-1 alpha-3 codes are three-letter country codes defined in ISO 3166-1, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest. They allow a better visual association between the codes and the country names than the two-letter alpha-2 codes (the third set of codes is numeric and hence offers no visual association). They were first included as part of the ISO 3166 standard in its first edition in 1974. Uses and applications The ISO 3166-1 alpha-3 codes are used most prominently in ISO/IEC 7501-1 for machine-readable passports, as standardized by the International Civil Aviation Organization, with a number of additional codes for special passports; some of these codes are currently reserved and not used at the present stage in ISO 3166-1. The United Nations uses a combination of ISO 3166-1 alpha-2 and alpha-3 codes, along with codes that p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wi-Fi
Wi-Fi () is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks in the world, used globally in home and small office networks to link desktop and laptop computers, tablet computers, smartphones, smart TVs, printers, and smart speakers together and to a wireless router to connect them to the Internet, and in wireless access points in public places like coffee shops, hotels, libraries and airports to provide visitors with Internet access for their mobile devices. ''Wi-Fi'' is a trademark of the non-profit Wi-Fi Alliance, which restricts the use of the term ''Wi-Fi Certified'' to products that successfully complete interoperability certification testing. the Wi-Fi Alliance consisted of more than 800 companies from around the world. over 3.05 billion ...

Territories Of The United States
Territories of the United States are sub-national administrative divisions overseen by the federal government of the United States. The various American territories differ from the U.S. states and Indian reservation, tribal reservations as they are not Sovereignty, sovereign entities. In contrast, each state has a sovereignty separate from that of the federal government and each federally recognized Native American tribe possesses limited tribal sovereignty in the United States, tribal sovereignty as a "dependent sovereign nation". Territories are classified by #Incorporated vs. unincorporated territories, incorporation and whether they have an "organized" government through an organic act passed by the United States Congress, Congress. American territories are under American sovereignty and, consequently, may be treated as part of the United States ''proper'' in some ways and not others (i.e., territories belong to, but are not considered to be a part of, the United States). ...

International Telecommunication Union
The International Telecommunication Union is a specialized agency of the United Nations responsible for many matters related to information and communication technologies. It was established on 17 May 1865 as the International Telegraph Union, making it the oldest UN agency. The ITU was initially aimed at helping connect telegraphic networks between countries, with its mandate consistently broadening with the advent of new communications technologies; it adopted its current name in 1932 to reflect its expanded responsibilities over radio and the telephone. On 15 November 1947, the ITU entered into an agreement with the newly created United Nations to become a specialized agency within the UN system, which formally entered into force on 1 January 1949. The ITU promotes the shared global use of the radio spectrum, facilitates international cooperation in assigning satellite orbits, assists in developing and coordinating worldwide technical standards, and works to improve tele ...
