Telecommunication is the transmission of signs, messages, writings and sounds or information of any nature by wire, optical or other electromagnetic systems. Telecommunication occurs when the exchange of information between communication participants includes the use of technology, it is transmitted either electrically over physical media, such as cables, or via electromagnetic radiation. Such transmission paths are divided into communication channels which afford the advantages of multiplexing. Since the Latin term communicatio is considered the social process of information exchange, the term telecommunications is used in its plural form because it involves many different technologies. Early means of communicating over a distance included visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, optical heliographs. Other examples of pre-modern long-distance communication included audio messages such as coded drumbeats, lung-blown horns, loud whistles. 20th- and 21st-century technologies for long-distance communication involve electrical and electromagnetic technologies, such as telegraph and teleprinter, radio, microwave transmission, fiber optics, communications satellites.
A revolution in wireless communication began in the first decade of the 20th century with the pioneering developments in radio communications by Guglielmo Marconi, who won the Nobel Prize in Physics in 1909, other notable pioneering inventors and developers in the field of electrical and electronic telecommunications. These included Charles Wheatstone and Samuel Morse, Alexander Graham Bell, Edwin Armstrong and Lee de Forest, as well as Vladimir K. Zworykin, John Logie Baird and Philo Farnsworth; the word telecommunication is a compound of the Greek prefix tele, meaning distant, far off, or afar, the Latin communicare, meaning to share. Its modern use is adapted from the French, because its written use was recorded in 1904 by the French engineer and novelist Édouard Estaunié. Communication was first used as an English word in the late 14th century, it comes from Old French comunicacion, from Latin communicationem, noun of action from past participle stem of communicare "to share, divide out.
Homing pigeons have been used throughout history by different cultures. Pigeon post had Persian roots, was used by the Romans to aid their military. Frontinus said; the Greeks conveyed the names of the victors at the Olympic Games to various cities using homing pigeons. In the early 19th century, the Dutch government used the system in Sumatra, and in 1849, Paul Julius Reuter started a pigeon service to fly stock prices between Aachen and Brussels, a service that operated for a year until the gap in the telegraph link was closed. In the Middle Ages, chains of beacons were used on hilltops as a means of relaying a signal. Beacon chains suffered the drawback that they could only pass a single bit of information, so the meaning of the message such as "the enemy has been sighted" had to be agreed upon in advance. One notable instance of their use was during the Spanish Armada, when a beacon chain relayed a signal from Plymouth to London. In 1792, Claude Chappe, a French engineer, built the first fixed visual telegraphy system between Lille and Paris.
However semaphore suffered from the need for skilled operators and expensive towers at intervals of ten to thirty kilometres. As a result of competition from the electrical telegraph, the last commercial line was abandoned in 1880. On 25 July 1837 the first commercial electrical telegraph was demonstrated by English inventor Sir William Fothergill Cooke, English scientist Sir Charles Wheatstone. Both inventors viewed their device as "an improvement to the electromagnetic telegraph" not as a new device. Samuel Morse independently developed a version of the electrical telegraph that he unsuccessfully demonstrated on 2 September 1837, his code was an important advance over Wheatstone's signaling method. The first transatlantic telegraph cable was completed on 27 July 1866, allowing transatlantic telecommunication for the first time; the conventional telephone was invented independently by Alexander Bell and Elisha Gray in 1876. Antonio Meucci invented the first device that allowed the electrical transmission of voice over a line in 1849.
However Meucci's device was of little practical value because it relied upon the electrophonic effect and thus required users to place the receiver in their mouth to "hear" what was being said. The first commercial telephone services were set-up in 1878 and 1879 on both sides of the Atlantic in the cities of New Haven and London. Starting in 1894, Italian inventor Guglielmo Marconi began developing a wireless communication using the newly discovered phenomenon of radio waves, showing by 1901 that they could be transmitted across the Atlantic Ocean; this was the start of wireless telegraphy by radio. Voice and music had little early success. World War I accelerated the development of radio for military communications. After the war, commercial radio AM broadcasting began in the 1920s and became an important mass medium for entertainment and news. World War II again accelerated development of radio for the wartime purposes of aircraft and land communication, radio navigation and radar. Development of stereo FM broadcasting of radio
The United Kingdom the United Kingdom of Great Britain and Northern Ireland, sometimes referred to as Britain, is a sovereign country located off the north-western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, many smaller islands. Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state, the Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to the east, the English Channel to the south and the Celtic Sea to the south-west, giving it the 12th-longest coastline in the world; the Irish Sea lies between Great Ireland. With an area of 242,500 square kilometres, the United Kingdom is the 78th-largest sovereign state in the world, it is the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017. The UK is constitutional monarchy; the current monarch is Queen Elizabeth II, who has reigned since 1952, making her the longest-serving current head of state.
The United Kingdom's capital and largest city is London, a global city and financial centre with an urban area population of 10.3 million. Other major urban areas in the UK include Greater Manchester, the West Midlands and West Yorkshire conurbations, Greater Glasgow and the Liverpool Built-up Area; the United Kingdom consists of four constituent countries: England, Scotland and Northern Ireland. Their capitals are London, Edinburgh and Belfast, respectively. Apart from England, the countries have their own devolved governments, each with varying powers, but such power is delegated by the Parliament of the United Kingdom, which may enact laws unilaterally altering or abolishing devolution; the nearby Isle of Man, Bailiwick of Guernsey and Bailiwick of Jersey are not part of the UK, being Crown dependencies with the British Government responsible for defence and international representation. The medieval conquest and subsequent annexation of Wales by the Kingdom of England, followed by the union between England and Scotland in 1707 to form the Kingdom of Great Britain, the union in 1801 of Great Britain with the Kingdom of Ireland created the United Kingdom of Great Britain and Ireland.
Five-sixths of Ireland seceded from the UK in 1922, leaving the present formulation of the United Kingdom of Great Britain and Northern Ireland. There are fourteen British Overseas Territories, the remnants of the British Empire which, at its height in the 1920s, encompassed a quarter of the world's land mass and was the largest empire in history. British influence can be observed in the language and political systems of many of its former colonies; the United Kingdom is a developed country and has the world's fifth-largest economy by nominal GDP and ninth-largest economy by purchasing power parity. It has a high-income economy and has a high Human Development Index rating, ranking 14th in the world, it was the world's first industrialised country and the world's foremost power during the 19th and early 20th centuries. The UK remains a great power, with considerable economic, military and political influence internationally, it is sixth in military expenditure in the world. It has been a permanent member of the United Nations Security Council since its first session in 1946.
It has been a leading member state of the European Union and its predecessor, the European Economic Community, since 1973. The United Kingdom is a member of the Commonwealth of Nations, the Council of Europe, the G7, the G20, NATO, the Organisation for Economic Co-operation and Development and the World Trade Organization; the 1707 Acts of Union declared that the kingdoms of England and Scotland were "United into One Kingdom by the Name of Great Britain". The term "United Kingdom" has been used as a description for the former kingdom of Great Britain, although its official name from 1707 to 1800 was "Great Britain"; the Acts of Union 1800 united the kingdom of Great Britain and the kingdom of Ireland in 1801, forming the United Kingdom of Great Britain and Ireland. Following the partition of Ireland and the independence of the Irish Free State in 1922, which left Northern Ireland as the only part of the island of Ireland within the United Kingdom, the name was changed to the "United Kingdom of Great Britain and Northern Ireland".
Although the United Kingdom is a sovereign country, Scotland and Northern Ireland are widely referred to as countries. The UK Prime Minister's website has used the phrase "countries within a country" to describe the United Kingdom; some statistical summaries, such as those for the twelve NUTS 1 regions of the United Kingdom refer to Scotland and Northern Ireland as "regions". Northern Ireland is referred to as a "province". With regard to Northern Ireland, the descriptive name used "can be controversial, with the choice revealing one's political preferences"; the term "Great Britain" conventionally refers to the island of Great Britain, or politically to England and Wales in combination. However, it is sometimes used as a loose synonym for the United Kingdom as a whole; the term "Britain" is used both as a synonym for Great Britain, as a synonym for the United Kingdom. Usage is mixed, with the BBC preferring to use Britain as shorthand only for Great Britain and the UK Government, while accepting that both terms refer to the United K
Radio is the technology of signalling or communicating using radio waves. Radio waves are electromagnetic waves of frequency between 300 gigahertz, they are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, received by a radio receiver connected to another antenna. Radio is widely used in modern technology, in radio communication, radio navigation, remote control, remote sensing and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking and satellite communication among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal in the transmitter. In radar, used to locate and track objects like aircraft, ships and missiles, a beam of radio waves emitted by a radar transmitter reflects off the target object, the reflected waves reveal the object's location. In radio navigation systems such as GPS and VOR, a mobile receiver receives radio signals from navigational radio beacons whose position is known, by measuring the arrival time of the radio waves the receiver can calculate its position on Earth.
In wireless remote control devices like drones, garage door openers, keyless entry systems, radio signals transmitted from a controller device control the actions of a remote device. Applications of radio waves which do not involve transmitting the waves significant distances, such as RF heating used in industrial processes and microwave ovens, medical uses such as diathermy and MRI machines, are not called radio; the noun radio is used to mean a broadcast radio receiver. Radio waves were first identified and studied by German physicist Heinrich Hertz in 1886; the first practical radio transmitters and receivers were developed around 1895-6 by Italian Guglielmo Marconi, radio began to be used commercially around 1900. To prevent interference between users, the emission of radio waves is regulated by law, coordinated by an international body called the International Telecommunications Union, which allocates frequency bands in the radio spectrum for different uses. Radio waves are radiated by electric charges undergoing acceleration.
They are generated artificially by time varying electric currents, consisting of electrons flowing back and forth in a metal conductor called an antenna. In transmission, a transmitter generates an alternating current of radio frequency, applied to an antenna; the antenna radiates the power in the current as radio waves. When the waves strike the antenna of a radio receiver, they push the electrons in the metal back and forth, inducing a tiny alternating current; the radio receiver connected to the receiving antenna detects this oscillating current and amplifies it. As they travel further from the transmitting antenna, radio waves spread out so their signal strength decreases, so radio transmissions can only be received within a limited range of the transmitter, the distance depending on the transmitter power, antenna radiation pattern, receiver sensitivity, noise level, presence of obstructions between transmitter and receiver. An omnidirectional antenna transmits or receives radio waves in all directions, while a directional antenna or high gain antenna transmits radio waves in a beam in a particular direction, or receives waves from only one direction.
Radio waves travel through a vacuum at the speed of light, in air at close to the speed of light, so the wavelength of a radio wave, the distance in meters between adjacent crests of the wave, is inversely proportional to its frequency. In radio communication systems, information is carried across space using radio waves. At the sending end, the information to be sent is converted by some type of transducer to a time-varying electrical signal called the modulation signal; the modulation signal may be an audio signal representing sound from a microphone, a video signal representing moving images from a video camera, or a digital signal consisting of a sequence of bits representing binary data from a computer. The modulation signal is applied to a radio transmitter. In the transmitter, an electronic oscillator generates an alternating current oscillating at a radio frequency, called the carrier wave because it serves to "carry" the information through the air; the information signal is used to modulate the carrier, varying some aspect of the carrier wave, impressing the information on the carrier.
Different radio systems use different modulation methods: AM - in an AM transmitter, the amplitude of the radio carrier wave is varied by the modulation signal. FM - in an FM transmitter, the frequency of the radio carrier wave is varied by the modulation signal. FSK - used in wireless digital devices to transmit digital signals, the frequency of the carrier wave is shifted periodically between two frequencies that represent the two binary digits, 0 and 1, to transmit a sequence of bits. OFDM - a family of complicated digital modulation methods widely used in high bandwidth systems such as WiFi networks, digital television broadcasting, digital audio broadcasting to transmit digital data using a minimum of radio spectrum bandwidth. OFDM has higher spectral efficiency and more resistance to fading than AM or FM. Multiple radio carrier waves spaced in frequency are transmitted within the radio channel, with each carrier modulated with bits from the incoming bitstream
A mobile phone, cell phone, cellphone, or hand phone, sometimes shortened to mobile, cell or just phone, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network. Modern mobile telephone services use a cellular network architecture, therefore, mobile telephones are called cellular telephones or cell phones, in North America. In addition to telephony, 2000s-era mobile phones support a variety of other services, such as text messaging, MMS, Internet access, short-range wireless communications, business applications, video games, digital photography. Mobile phones offering only those capabilities are known as feature phones; the first handheld mobile phone was demonstrated by John F. Mitchell and Martin Cooper of Motorola in 1973, using a handset weighing c. 2 kilograms.
In 1979, Nippon Telegraph and Telephone launched the world's first cellular network in Japan. In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. From 1983 to 2014, worldwide mobile phone subscriptions grew to over seven billion—enough to provide one for every person on Earth. In first quarter of 2016, the top smartphone developers worldwide were Samsung and Huawei, smartphone sales represented 78 percent of total mobile phone sales. For feature phones as of 2016, the largest were Samsung and Alcatel. A handheld mobile radio telephone service was envisioned in the early stages of radio engineering. In 1917, Finnish inventor Eric Tigerstedt filed a patent for a "pocket-size folding telephone with a thin carbon microphone". Early predecessors of cellular phones included analog radio communications from trains; the race to create portable telephone devices began after World War II, with developments taking place in many countries. The advances in mobile telephony have been traced in successive "generations", starting with the early zeroth-generation services, such as Bell System's Mobile Telephone Service and its successor, the Improved Mobile Telephone Service.
These 0G systems were not cellular, supported few simultaneous calls, were expensive. The first handheld cellular mobile phone was demonstrated by John F. Mitchell and Martin Cooper of Motorola in 1973, using a handset weighing 2 kilograms; the first commercial automated cellular network analog was launched in Japan by Nippon Telegraph and Telephone in 1979. This was followed in 1981 by the simultaneous launch of the Nordic Mobile Telephone system in Denmark, Finland and Sweden. Several other countries followed in the early to mid-1980s; these first-generation systems could support far more simultaneous calls but still used analog cellular technology. In 1983, the DynaTAC 8000x was the first commercially available handheld mobile phone. In 1991, the second-generation digital cellular technology was launched in Finland by Radiolinja on the GSM standard; this sparked competition in the sector as the new operators challenged the incumbent 1G network operators. Ten years in 2001, the third generation was launched in Japan by NTT DoCoMo on the WCDMA standard.
This was followed by 3.5G, 3G+ or turbo 3G enhancements based on the high-speed packet access family, allowing UMTS networks to have higher data transfer speeds and capacity. By 2009, it had become clear that, at some point, 3G networks would be overwhelmed by the growth of bandwidth-intensive applications, such as streaming media; the industry began looking to data-optimized fourth-generation technologies, with the promise of speed improvements up to ten-fold over existing 3G technologies. The first two commercially available technologies billed as 4G were the WiMAX standard, offered in North America by Sprint, the LTE standard, first offered in Scandinavia by TeliaSonera. 5G is a technology and term used in research papers and projects to denote the next major phase in mobile telecommunication standards beyond the 4G/IMT-Advanced standards. The term 5G is not used in any specification or official document yet made public by telecommunication companies or standardization bodies such as 3GPP, WiMAX Forum or ITU-R.
New standards beyond 4G are being developed by standardization bodies, but they are at this time seen as under the 4G umbrella, not for a new mobile generation. Smartphones have a number of distinguishing features; the International Telecommunication Union measures those with Internet connection, which it calls Active Mobile-Broadband subscriptions. In the developed world, smartphones have now overtaken the usage of earlier mobile systems. However, in the developing world, they account for around 50% of mobile telephony. Feature phone is a term used as a retronym to describe mobile phones which are limited in capabilities in contrast to a modern smartphone. Feature phones provide voice calling and text messaging functionality, in addition to basic multimedia and Internet capabilities, other services offered by the user's wireless service provider. A feature phone has additional functions over and above a basic mobile phone, only capable of voice calling and text messaging. Feature phones and basic mobile phones tend to use a proprietary, custom-designed software and user interface.
By contrast, smartphones use a mobile operating system that shares common traits across devices. There are Orthodox Jewish religious re
Verizon Communications Inc. is an American multinational telecommunications conglomerate and a corporate component of the Dow Jones Industrial Average. The company is based at 1095 Avenue of the Americas in Midtown Manhattan, New York City, but is incorporated in Delaware. In 1984, the United States Department of Justice mandated AT&T Corporation to break up the Bell System and split into seven companies, called "Baby Bells". One of the baby bells, Bell Atlantic, came into existence in 1984 consisting of the separate operating companies New Jersey Bell, Bell of Pennsylvania, Diamond State Telephone, C&P Telephone, with a footprint from New Jersey to Virginia; this company would become Verizon. As part of a rebranding of the Baby Bells in the mid-1990s, all of Bell Atlantic's operating companies assumed the holding company's name. In 1997, Bell Atlantic expanded into New York and the New England states by merging with fellow Baby Bell NYNEX. Although Bell Atlantic was the surviving company name, the merged company moved its headquarters from Philadelphia to NYNEX's old headquarters in New York City.
In 2000, Bell Atlantic acquired GTE, which operated telecommunications companies across most of the rest of the country, not in Bell Atlantic's footprint. Bell Atlantic, the surviving entity, changed its name to "Verizon", a portmanteau of veritas and horizon. In 2015, Verizon expanded its business into content ownership by acquiring AOL, two years it acquired Yahoo!. AOL and Yahoo were amalgamated into a new division named Oath Inc.. As of 2016, Verizon is one of three remaining companies that had their roots in the former Baby Bells; the other two, like Verizon, exist as a result of mergers among fellow former Baby Bell members. SBC Communications, bought out the Bells' former parent AT&T Corporation, assumed the AT&T name. CenturyLink was formed in 2011 by the acquisition of Qwest. Verizon's subsidiary Verizon Wireless is the largest U. S. wireless communications service provider as of September 2014, with 147 million mobile customers. And as of 2017, Verizon is the only publicly-traded telecommunications company to have two stock listings in its home country, both the NYSE and NASDAQ.
As of 2017, it is the second largest telecommunications company by revenue after AT&T. Bell Atlantic Corporation was created as one of the original Regional Bell Operating Companies in 1984, during the breakup of the Bell System. Bell Atlantic's original roster of operating companies included: The Bell Telephone Company of Pennsylvania New Jersey Bell Diamond State Telephone C&P Telephone Bell Atlantic operated in the states of New Jersey, Delaware, West Virginia, Virginia, as well as Washington, DC. In 1996, CEO and Chairman Raymond W. Smith orchestrated Bell Atlantic's merger with NYNEX; when it merged, it moved its corporate headquarters from Philadelphia to New York City. NYNEX was consolidated into this name by 1997. Bell Atlantic changed its name to Verizon Communications in June 2000 when the Federal Communications Commission approved the US$64.7 billion Merger with telephone company GTE, nearly two years after the deal was proposed in July 1998. The approval came with 25 stipulations to preserve competition between local phone carriers, including investing in new markets and broadband technologies.
The new entity was headed by co-CEOs Charles Lee the CEO of GTE, Bell Atlantic CEO Ivan Seidenberg. Verizon became the largest local telephone company in the United States, operating 63 million telephone lines in 40 states; the company inherited 25 million mobile phone customers. Additionally, Verizon offered internet services and long-distance calling in New York, before expanding long-distance operations to other states; the name Verizon derives from the combination of the words veritas, Latin for truth, horizon. The name was chosen from 8,500 candidates and the company spent $300 million on marketing the new brand. Two months before the FCC gave final approval on the formation of Verizon Communications, Bell Atlantic formed Verizon Wireless in a joint venture with the British telecommunications company Vodafone in April 2000; the companies established Verizon Wireless as its own business operated by Bell Atlantic, which owned 55% of the venture. Vodafone retained 45% of the company; the deal was valued at $70 billion and created a mobile carrier with 23 million customers.
Verizon Wireless merged Bell Atlantic's wireless network, Vodafone's AirTouch and PrimeCo holdings, the wireless division of GTE. Due to its size, Verizon Wireless was able to offer national coverage at competitive rates, giving it an advantage over regional providers typical of the time. During its first operational year, Verizon Wireless released Mobile Web, an Internet service that allowed customers to access partner sites such as E*Trade, ABC News, ESPN, Amazon.com, Ticketmaster and MSN, as well as the "New Every Two" program, which gave customers a free phone with every two-year service contract. In another partnership with MSN in 2002, Verizon Wireless launched the mobile content service "VZW with MSN" and a phone that utilized the Microsoft Windows operating system. In August 2000 85,000 Verizon workers went on an 18-day labor strike after their union contracts expired; the strike affected quarterly revenues, resulting in Verizon Wireless' postponement of the company's IPO, created a backlog of repairs.
Verizon launched 3G service in 2002, which doubled the Internet speeds of t
Alexandria is the second-largest city in Egypt and a major economic centre, extending about 32 km along the coast of the Mediterranean Sea in the north central part of the country. Its low elevation on the Nile delta makes it vulnerable to rising sea levels. Alexandria is an important industrial center because of its natural oil pipelines from Suez. Alexandria is a popular tourist destination. Alexandria was founded around a small, ancient Egyptian town c. 332 BC by Alexander the Great, king of Macedon and leader of the Greek League of Corinth, during his conquest of the Achaemenid Empire. Alexandria became an important center of Hellenistic civilization and remained the capital of Ptolemaic Egypt and Roman and Byzantine Egypt for 1,000 years, until the Muslim conquest of Egypt in AD 641, when a new capital was founded at Fustat. Hellenistic Alexandria was best known for the Lighthouse of Alexandria, one of the Seven Wonders of the Ancient World. Alexandria was at one time the second most powerful city of the ancient Mediterranean region, after Rome.
Ongoing maritime archaeology in the harbor of Alexandria, which began in 1994, is revealing details of Alexandria both before the arrival of Alexander, when a city named Rhacotis existed there, during the Ptolemaic dynasty. From the late 18th century, Alexandria became a major center of the international shipping industry and one of the most important trading centers in the world, both because it profited from the easy overland connection between the Mediterranean Sea and the Red Sea, the lucrative trade in Egyptian cotton. Alexandria is believed to have been founded by Alexander the Great in April 331 BC as Ἀλεξάνδρεια. Alexander's chief architect for the project was Dinocrates. Alexandria was intended to supersede Naucratis as a Hellenistic center in Egypt, to be the link between Greece and the rich Nile valley. Although it has long been believed only a small village there, recent radiocarbon dating of seashell fragments and lead contamination show significant human activity at the location for two millennia preceding Alexandria's founding.
Alexandria was the cultural center of the ancient world for some time. The city and its museum attracted many of the greatest scholars, including Greeks and Syrians; the city was plundered and lost its significance. In the early Christian Church, the city was the center of the Patriarchate of Alexandria, one of the major centers of early Christianity in the Eastern Roman Empire. In the modern world, the Coptic Orthodox Church and the Greek Orthodox Church of Alexandria both lay claim to this ancient heritage. Just east of Alexandria, there was in ancient times marshland and several islands; as early as the 7th century BC, there existed important port cities of Heracleion. The latter was rediscovered under water. An Egyptian city, Rhakotis existed on the shore and gave its name to Alexandria in the Egyptian language, it continued to exist as the Egyptian quarter of the city. A few months after the foundation, Alexander never returned to his city. After Alexander's departure, his viceroy, continued the expansion.
Following a struggle with the other successors of Alexander, his general Ptolemy Lagides succeeded in bringing Alexander's body to Alexandria, though it was lost after being separated from its burial site there. Although Cleomenes was in charge of overseeing Alexandria's continuous development, the Heptastadion and the mainland quarters seem to have been Ptolemaic work. Inheriting the trade of ruined Tyre and becoming the center of the new commerce between Europe and the Arabian and Indian East, the city grew in less than a generation to be larger than Carthage. In a century, Alexandria had become the largest city in the world and, for some centuries more, was second only to Rome, it became Egypt's main Greek city, with Greek people from diverse backgrounds. Alexandria was not only a center of Hellenism, but was home to the largest urban Jewish community in the world; the Septuagint, a Greek version of the Tanakh, was produced there. The early Ptolemies kept it in order and fostered the development of its museum into the leading Hellenistic center of learning, but were careful to maintain the distinction of its population's three largest ethnicities: Greek and Egyptian.
By the time of Augustus, the city walls encompassed an area of 5.34 km2, the total population in Roman times was around 500-600,000. According to Philo of Alexandria, in the year 38 of the Common era, disturbances erupted between Jews and Greek citizens of Alexandria during a visit paid by the Jewish king Agrippa I to Alexandria, principally over the respect paid by the Jewish nation to the Roman emperor, which escalated to open affronts and violence between the two ethnic groups and the desecration of Alexandrian synagogues; the violence was quelled after Caligula intervened and had the Roman governor, removed from the city. In AD 115, large parts of Alexandria were destroyed during the Kitos War, which gave Hadrian and his architect, Decriannus, an opportunity to rebuild it. In 215, the emperor Caracalla visited the city and, because of some insulting satires that the inhabitants had directed at him, abruptly commanded his troops to put to death all youths capable of bearing arms.

Movistar is a major telecommunications brand owned by Telefónica, operating in Spain and in many Hispanic American countries. It is the largest mobile phone operator in Spain with 22 million customers and 41.58% of market share, where it markets landline and pay television. Its principal competitor in Latin America is América Móvil; the Movistar brand has been in use in Spain since the launch of GSM services in 1995. The name became effective worldwide on April 5, 2005, after Telefónica purchased the BellSouth mobile operations branch in South America. After the purchase of O2 in 2005 by Telefónica, the company announced that the O2 brand would continue to be used in the UK, Germany and Ireland, as a separate branch with its own board and management structure. Since 2011, Telefónica has sponsored a UCI ProTeam squad in cycling under the name of Movistar Team, since 2014, the MotoGP team Movistar Yamaha MotoGP. A Disney and Telefónica deal brought Star Wars programming to Movistar+ schedule during October and November 2015 plus a pop up Star Wars pay channel starting in early December leading up to Force Awakens.
The programming consisted of making of documentaries. Among the extra include San Diego Comic-Con The Star Wars Celebration program, Star Wars Universe documentary and The Fans' Empire. Disney and Moviestar pop up channel leading up The Last Jedi. Duplicating the Sky Movies Disney arrangement in the UK, Movistar+ launched Movistar Disney on 22 December 2017. Argentina Chile Colombia Costa Rica Ecuador El Salvador Guatemala Mexico Nicaragua Panama Peru Spain Uruguay Venezuela Brazil Germany United Kingdom Czech republic The 1983 song "Walking on Sunshine" by Katrina and the Waves was used by Telefónica to announce the unification of all its operation brands in Latin America and Spain under the Movistar brand after the takeover of BellSouth's Latin America division.1. Movistar has used the New Radicals' hit "You Get What You Give", "Two Princes" by Spin Doctors and "Hey, Soul Sister" by Train, other versions of the song, in audiovisual advertisement.
