Finland
–
Finland, officially the Republic of Finland, is a sovereign state in Northern Europe. A peninsula with the Gulf of Finland to the south and the Gulf of Bothnia to the west, the country has borders with Sweden to the northwest, Norway to the north. Estonia is south of the country across the Gulf of Finland, Finland is a Nordic country situated in the geographical region of Fennoscandia, which also includes Scandinavia. Finlands population is 5.5 million, and the majority of the population is concentrated in the southern region,88. 7% of the population is Finnish people who speak Finnish, a Uralic language unrelated to the Scandinavian languages, the second major group are the Finland-Swedes. In terms of area, it is the eighth largest country in Europe, Finland is a parliamentary republic with a central government based in the capital Helsinki, local governments in 311 municipalities, and an autonomous region, the Åland Islands. Over 1.4 million people live in the Greater Helsinki metropolitan area, from the late 12th century, Finland was an integral part of Sweden, a legacy reflected in the prevalence of the Swedish language and its official status. In the spirit of the notion of Adolf Ivar Arwidsson, we are not Swedes, we do not want to become Russians, let us therefore be Finns, nevertheless, in 1809, Finland was incorporated into the Russian Empire as the autonomous Grand Duchy of Finland. In 1906, Finland became the nation in the world to give the right to vote to all adult citizens. Following the 1917 Russian Revolution, Finland declared itself independent, in 1918, the fledgling state was divided by civil war, with the Bolshevik-leaning Reds supported by the equally new Soviet Russia, fighting the Whites, supported by the German Empire. After a brief attempt to establish a kingdom, the became a republic. During World War II, the Soviet Union sought repeatedly to occupy Finland, with Finland losing parts of Karelia, Salla and Kuusamo, Petsamo and some islands, Finland joined the United Nations in 1955 and established an official policy of neutrality. The Finno-Soviet Treaty of 1948 gave the Soviet Union some leverage in Finnish domestic politics during the Cold War era, Finland was a relative latecomer to industrialization, remaining a largely agrarian country until the 1950s. It rapidly developed an advanced economy while building an extensive Nordic-style welfare state, resulting in widespread prosperity, however, Finnish GDP growth has been negative in 2012–2014, with a preceding nadir of −8% in 2009. Finland is a top performer in numerous metrics of national performance, including education, economic competitiveness, civil liberties, quality of life, a large majority of Finns are members of the Evangelical Lutheran Church, though freedom of religion is guaranteed under the Finnish Constitution. The first known appearance of the name Finland is thought to be on three rune-stones. Two were found in the Swedish province of Uppland and have the inscription finlonti, the third was found in Gotland, in the Baltic Sea. It has the inscription finlandi and dates from the 13th century, the name can be assumed to be related to the tribe name Finns, which is mentioned first known time AD98. The name Suomi has uncertain origins, but a candidate for a source is the Proto-Baltic word *źemē, in addition to the close relatives of Finnish, this name is also used in the Baltic languages Latvian and Lithuanian

Communication
–
Communication is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules. The main steps inherent to all communication are, The forming of communicative motivation or reason, transmission of the encoded message as a sequence of signals using a specific channel or medium. Noise sources such as forces and in some cases human activity begin influencing the quality of signals propagating from the sender to one or more receivers. Reception of signals and reassemblying of the message from a sequence of received signals. Decoding of the encoded message. Interpretation and making sense of the original message. The channel of communication can be visual, auditory, tactile and haptic, olfactory, electromagnetic, human communication is unique for its extensive use of abstract language. Development of civilization has been linked with progress in telecommunication. Nonverbal communication describes the process of conveying information in the form of non-linguistic representations, examples of nonverbal communication include haptic communication, chronemic communication, gestures, body language, facial expressions, eye contact, and how one dresses. Nonverbal communication also relates to intent of a message, examples of intent are voluntary, intentional movements like shaking a hand or winking, as well as involuntary, such as sweating. Speech also contains nonverbal elements known as paralanguage, e. g. rhythm, intonation, tempo and it affects communication most at the subconscious level and establishes trust. Likewise, written texts include nonverbal elements such as handwriting style, spatial arrangement of words, Nonverbal communication demonstrates one of Wazlawicks laws, you cannot not communicate. Once proximity has formed awareness, living creatures begin interpreting any signals received, Nonverbal cues are heavily relied on to express communication and to interpret others’ communication and can replace or substitute verbal messages. There are several reasons as to why non-verbal communication plays a role in communication. Written communication can also have non-verbal attributes, e-mails and web chats allow individual’s the option to change text font colours, stationary, emoticons, and capitalization in order to capture non-verbal cues into a verbal medium. Many different non-verbal channels are engaged at the time in communication acts. “Non-verbal behaviours may form a language system. ”Smiling, crying, pointing, caressing. Such non-verbal signals allow the most basic form of communication when verbal communication is not effective due to language barriers, Verbal communication is the spoken or written conveyance of a message

Optical fiber
–
An optical fiber or optical fibre is a flexible, transparent fiber made by drawing glass or plastic to a diameter slightly thicker than that of a human hair. Fibers are also used for illumination, and are wrapped in bundles so that they may be used to carry images, thus allowing viewing in confined spaces, as in the case of a fiberscope. Specially designed fibers are used for a variety of other applications, some of them being fiber optic sensors. Optical fibers typically include a transparent core surrounded by a transparent cladding material with an index of refraction. Light is kept in the core by the phenomenon of internal reflection which causes the fiber to act as a waveguide. Fibers that support many propagation paths or transverse modes are called multi-mode fibers, multi-mode fibers generally have a wider core diameter and are used for short-distance communication links and for applications where high power must be transmitted. Single-mode fibers are used for most communication links longer than 1,000 meters, being able to join optical fibers with low loss is important in fiber optic communication. This is more complex than joining electrical wire or cable and involves careful cleaving of the fibers, precise alignment of the cores. For applications that demand a permanent connection a fusion splice is common, in this technique, an electric arc is used to melt the ends of the fibers together. Another common technique is a splice, where the ends of the fibers are held in contact by mechanical force. Temporary or semi-permanent connections are made by means of specialized optical fiber connectors, the field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. The term was coined by Indian physicist Narinder Singh Kapany who is acknowledged as the father of fiber optics. Guiding of light by refraction, the principle that makes fiber optics possible, was first demonstrated by Daniel Colladon, John Tyndall included a demonstration of it in his public lectures in London,12 years later. When the ray passes from water to air it is bent from the perpendicular. If the angle which the ray in water encloses with the perpendicular to the surface be greater than 48 degrees, the angle which marks the limit where total reflection begins is called the limiting angle of the medium. For water this angle is 48°27′, for flint glass it is 38°41′, unpigmented human hairs have also been shown to act as an optical fiber. Practical applications, such as close internal illumination during dentistry, appeared early in the twentieth century, image transmission through tubes was demonstrated independently by the radio experimenter Clarence Hansell and the television pioneer John Logie Baird in the 1920s. The principle was first used for medical examinations by Heinrich Lamm in the following decade

Cellular network
–
A cellular network or mobile network is a communication network where the last link is wireless. The network is distributed over land areas called cells, each served by at least one fixed-location transceiver and this base station provides the cell with the network coverage which can be used for transmission of voice, data and others. A cell might use a different set of frequencies from neighboring cells, to avoid interference, when joined together these cells provide radio coverage over a wide geographic area. This allows mobile phones and mobile computing devices to be connected to the switched telephone network. Private cellular networks can be used for research or for large organizations and fleets, each of these cells is assigned with multiple frequencies which have corresponding radio base stations. The group of frequencies can be reused in other cells, provided that the frequencies are not reused in adjacent neighboring cells as that would cause co-channel interference. If there is a single transmitter, only one transmission can be used on any given frequency. Unfortunately, there is some level of interference from the signal from the other cells which use the same frequency. This means that, in a standard FDMA system, there must be at least a one cell gap between cells which reuse the same frequency, in the simple case of the taxi company, each radio had a manually operated channel selector knob to tune to different frequencies. As the drivers moved around, they would change from channel to channel, the drivers knew which frequency covered approximately what area. When they did not receive a signal from the transmitter, they would try other channels until they found one that worked, the taxi drivers would only speak one at a time, when invited by the base station operator. With TDMA, the transmitting and receiving time slots used by different users in each cell are different from each other, with FDMA, the transmitting and receiving frequencies used by different users in each cell are different from each other. In a simple system, the taxi driver manually tuned to a frequency of a chosen cell to obtain a strong signal. The principle of CDMA is more complex, but achieves the same result, time division multiple access is used in combination with either FDMA or CDMA in a number of systems to give multiple channels within the coverage area of a single cell. The key characteristic of a network is the ability to re-use frequencies to increase both coverage and capacity. The elements that determine frequency reuse are the distance and the reuse factor. The reuse distance, D is calculated as D = R3 N, cells may vary in radius from 1 to 30 kilometres. The boundaries of the cells can also overlap between adjacent cells and large cells can be divided into smaller cells, the frequency reuse factor is the rate at which the same frequency can be used in the network

Elisas revenue in 2016 was 1.64 billion euros and it employed 4,300 people, Elisa was originally established on 31 January 1882 by the electrical engineer Daniel Wadén as a telephone cooperative called the Helsinki Telephone Association. HPY began serving customers on 6 June 1882 by connecting 56 phone numbers, HPY started expanding during the 1930s by merging with smaller cooperative telephone operators. The company reached its current geographical operating field in 1958, the original form of incorporation, a mutual association, was changed to a legal cooperative in 1995. The cooperative was finally demutualised in 2000, Elisa launched the first commercial GSM service under the Radiolinja brand in 1991 and the worlds first commercial UMTS900 network on 8 November 2007. Investment company Novator Partners acquired a 10. 4% stake in Elisa in 2005 through a share swap when Elisa bought the smaller operator Saunalahti, Novator tried to revamp Elisa in December 2007, but was opposed by Finnish institutions such as Varma Mutual Pension Insurance Company. In October 2008, during the Icelandic financial crisis, Novator sold its stake in Elisa to Varma for 194 million euros

Telia Company
–
Telia Company AB is the dominant telephone company and mobile network operator in Sweden and Finland. The company has operations in countries in Northern and Eastern Europe. It is headquartered in Stockholm and its stock is traded on the Stockholm Stock Exchange, Telia Company is the result of a 2002 merger between the Swedish and Finnish telecommunications companies, Telia and Sonera. This merger followed shortly after Telias failed merger with Norwegian telecommunications company Telenor, before privatisation Telia Company was a state telephone monopoly. Sonera on the hand had a monopoly only on trunk network calls. The separate brand names Telia and Sonera have continued to be used in the Swedish and Finnish markets respectively. Of the stock, 37% is owned by the Swedish government,3. 2% by the Finnish government, and the rest by institutions, companies, Telegrafverket was founded in 1853, when the first electric telegraph line was established between Stockholm and Uppsala. Allmänna Telefon found an equipment supplier in Lars Magnus Ericsson, in this early competition, Telegrafverket with its brand Rikstelefon was a latecomer. However, by securing a monopoly on long distance telephone lines, it was able with time to control. A de facto telephone monopoly position was reached around 1920, in 1953 the name was modernised to Televerket. The operation of the radio and TV broadcast network was spun off into a company named Teracom. On 1 July 1993 the remaining telephone and mobile operator was transformed into a government-owned shareholding company. At the height of the bubble, on 13 June 2000. In the 1980s, Televerket was a mobile network operator with the NMT system. Private competition in mobile phone systems had already broken the telephone monopoly. The most important of Telias Swedish competitors in these areas has been Tele2, SUNAB was founded as the jointly owned company that would in turn build, own and operate the joint 3G network. The history of Sonera dates back to 1917, when Suomen Lennätinlaitos was founded, in 1927, the telegraph agency was merged with the Finnish Post to form a new agency, Post and Telegraph Agency. This agency governed all long distance and international calls until 1994, in the same year, the Post and Telegraph Agency was divided to form two companies, Suomen Posti Oy, and Telecom Finland Oy

Submarine
–
A submarine is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability, the term most commonly refers to a large, crewed vessel. It is also used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine. The noun submarine evolved as a form of submarine boat, by naval tradition, submarines are usually referred to as boats rather than as ships. Although experimental submarines had been built before, submarine design took off during the 19th century, Submarines were first widely used during World War I, and now figure in many navies large and small. Civilian uses for submarines include marine science, salvage, exploration and facility inspection, Submarines can also be modified to perform more specialized functions such as search-and-rescue missions or undersea cable repair. Submarines are also used in tourism, and for undersea archaeology, most large submarines consist of a cylindrical body with hemispherical ends and a vertical structure, usually located amidships, which houses communications and sensing devices as well as periscopes. In modern submarines, this structure is the sail in American usage, a conning tower was a feature of earlier designs, a separate pressure hull above the main body of the boat that allowed the use of shorter periscopes. There is a propeller at the rear, and various hydrodynamic control fins, smaller, deep-diving and specialty submarines may deviate significantly from this traditional layout. Submarines use diving planes and also change the amount of water, Submarines have one of the widest ranges of types and capabilities of any vessel. Submarines can work at greater depths than are survivable or practical for human divers, modern deep-diving submarines derive from the bathyscaphe, which in turn evolved from the diving bell. In 1578, the English mathematician William Bourne recorded in his book Inventions or Devises one of the first plans for an underwater navigation vehicle and its unclear whether he ever carried out his idea. The first submersible of whose construction there exists reliable information was designed and built in 1620 by Cornelis Drebbel and it was propelled by means of oars. By the mid-18th century, over a dozen patents for submarines/submersible boats had been granted in England, in 1747, Nathaniel Symons patented and built the first known working example of the use of a ballast tank for submersion. His design used leather bags that could fill with water to submerge the craft, a mechanism was used to twist the water out of the bags and cause the boat to resurface. In 1749, the Gentlemens Magazine reported that a design had initially been proposed by Giovanni Borelli in 1680. By this point of development, further improvement in design stagnated for over a century, until new industrial technologies for propulsion. The first military submarine was the Turtle, a hand-powered acorn-shaped device designed by the American David Bushnell to accommodate a single person and it was the first verified submarine capable of independent underwater operation and movement, and the first to use screws for propulsion

Estonia
–
Estonia, officially the Republic of Estonia, is a country in the Baltic region of Northern Europe. It is bordered to the north by the Gulf of Finland, to the west by the Baltic Sea, to the south by Latvia, across the Baltic Sea lies Sweden in the west and Finland in the north. The territory of Estonia consists of a mainland and 2,222 islands and islets in the Baltic Sea, covering 45,339 km2 of land and water, and is influenced by a humid continental climate. The territory of Estonia has been inhabited since at least 6500 BC, in 1988, during the Singing Revolution, the Estonian Supreme Soviet issued the Estonian Sovereignty Declaration in defiance of Soviet rule, and independence was restored on 20 August 1991. Estonia is a parliamentary republic divided into fifteen counties. Its capital and largest city is Tallinn, with a population of 1.3 million, it is one of the least-populous member states of the European Union, Eurozone, North Atlantic Treaty Organization, OECD and Schengen Area. Estonia is a country with an advanced, high-income economy that is among the fastest growing in the EU. Its Human Development Index ranks very highly, and it performs favourably in measurements of economic freedom, civil liberties, the 2015 PISA test places Estonian high school students 3rd in the world, behind Singapore and Japan. Citizens of Estonia are provided with health care, free education. Since independence the country has developed its IT sector, becoming one of the worlds most digitally advanced societies. In 2005 Estonia became the first nation to hold elections over the Internet, in the Estonian language, the oldest known endonym of the Estonians was maarahvas, meaning country people or people of the land. The land inhabited by Estonians was called Maavald meaning Country Parish or Land Parish, one hypothesis regarding the modern name of Estonia is that it originated from the Aesti, a people described by the Roman historian Tacitus in his Germania. The historic Aesti were allegedly Baltic people, whereas the modern Estonians are Finno-Ugric, the geographical areas between Aesti and Estonia do not match, with Aesti being further down south. Ancient Scandinavian sagas refer to a land called Eistland, as the country is called in Icelandic. Early Latin and other ancient versions of the name are Estia and Hestia, esthonia was a common alternative English spelling prior to 1921. Human settlement in Estonia became possible 13,000 to 11,000 years ago, the oldest known settlement in Estonia is the Pulli settlement, which was on the banks of the river Pärnu, near the town of Sindi, in south-western Estonia. According to radiocarbon dating it was settled around 11,000 years ago, the earliest human inhabitation during the Mesolithic period is connected to Kunda culture, which is named after the town of Kunda in northern Estonia. At that time the country was covered with forests, and people lived in communities near bodies of water
