Question: Information:  - Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries.  - Athens ("Athína" ) is the capital and largest city of Greece. Athens dominates the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years, and its earliest human presence starting somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state that emerged in conjunction with the seagoing development of the port of Piraeus, which had been a distinct city prior to its 5th century BC incorporation with Athens. A centre for the arts, learning and philosophy, home of Plato's Academy and Aristotle's Lyceum, it is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political impact on the European continent, and in particular the Romans. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Greece. In 2015, Athens was ranked the world's 29th richest city by purchasing power and the 67th most expensive in a UBS study.  - A grassroots movement (often referenced in the context of a political movement) is one which uses the people in a given district as the basis for a political or economic movement. Grassroots movements and organizations utilize collective action from the local level to effect change at the local, regional, national, or international level. Grassroots movements are associated with bottom-up, rather than top-down decision making, and are sometimes considered more natural or spontaneous than more traditional power structures. Grassroots movements, using self-organization, encourages community members to contribute by taking responsibility and action for their community. Grassroots movements utilize a variety of strategies from fundraising and registering voters, to simply encouraging political conversation. Goals of specific movements vary, but the movements are consistent in their focus on increasing mass participation in politics.  - Greece (' ), officially the Hellenic Republic (Greek: ' ), historically also known as Hellas ("" ), is a country in southeastern Europe.  Greece's population is approximately 10.955 million as of 2015. Athens is the nation's capital and largest city, followed by Thessaloniki.  - Thessaloniki is the second-largest city in Greece and the capital of Greek Macedonia, the administrative region of Central Macedonia and the Decentralized Administration of Macedonia and Thrace. Its nickname is   ("Symprotévousa"), literally "the co-capital", a reference to its historical status as the  ("Symvasilévousa") or "co-reigning" city of the Eastern Roman (Byzantine) Empire, alongside Constantinople.  - Wireless Thessaloniki is an experimental wireless community network growing in the air of Thessaloniki , Greece . It is one of the first wireless networks deployed in the city . It was founded by Konstantinos Natsakis and Athanasios Kanaris on November , 2002 . The primary goals of this project was twofold : Development of a floppy linux distribution that would provide encryption better than WEP Construction of low - cost antennas and routers based on old PCs , placed in water resist boxes in order to be placed on rooftops The linux floppy distribution formed , named Paladir , was named after the palantíri in J. R. R. Tolkien 's The Lord of the Rings , as it provided insight to other wireless routers running Paladir . The first wireless link , connecting two points with distance of 4.5 km , was achieved on March 1st , 2003 , in 11 Mbit / s. Since then , the wthess network counts more than 20 nodes sparged on rooftops of the city . It is connected with TWMN and SWN to provide connectivity with other community networks , and it is also connected through wired network with AWMN and other wireless communities in Greece .  - Wireless community networks or wireless community projects are the organizations that attempt to take a grassroots approach to providing a viable alternative to municipal wireless networks for consumers.  - Municipal wireless network (Municipal Wi-Fi, Muni Wi-Fi or Muni-Fi) is a city-wide wireless network. This is usually done by providing municipal broadband via Wi-Fi to large parts or all of a municipal area by deploying a wireless mesh network. The typical deployment design uses hundreds of wireless access points deployed outdoors, often on poles. The operator of the network acts as a wireless internet service provider.  - The euro (sign: €; code: EUR) is the official currency of the eurozone, which consists of 19 of the member states of the European Union: Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain. The currency is also officially used by the institutions of the European Union and four other European countries, as well as unilaterally by two others, and is consequently used daily by some 337 million Europeans . Outside of Europe, a number of overseas territories of EU members also use the euro as their currency.    Given the paragraphs above, decide what entity has the relation 'instance of' with 'municipal wireless network'.
Answer:
wireless thessaloniki
