Telecommunications/connectivity to and within Iceland Speaker: Jón Ingi Einarsson General Manager of RHnet, the University and research network of Iceland 1
Overview For the Icelanders the direct communications with the outside world did start through a submarine cable and later on through radio/ wireless. We will look briefly at that history and finish by the present state of affairs and mention a couple of future prospects. Also some details or overview of the cabling infrastructure will be given. 2
3 Long distance communication possible across an ocean? The first real breakthrough was in 1858 when the first transatlantic telegraph cable was laid (although it failed about three weeks later). This was done by two steamships as there was no ship available that could carry the whole cable, but to some it showed that this was possible. But others were not impressed and some reasoned that such a long cable would only be able to offer very slow communication speed. The picture is of Agamemnon, one of the steamships used to lay the cable in 1858 and shows a whale crossing the cable as it is layed. This caused a slight tension aboard as this was not anticipated.
Connecting the continents through Iceland? In 1854 a word came to Iceland that a man named T.P. Shaffner was interested in the laying of cable from Copenhagen to America, through Faroe Islands, Iceland and Greenland and he did make some surveys, but Others though it best to cross Siberia, the Bering Strait (82 km), to Alaska. Work on this route was started. 4
1866 A telegraph cable across the Atlantic 1866 is the year that the two continents were connected together, this time with an improved cable and the only ship able to carry the whole cable (about 5000 tons). The ship in question, Great Eastern, was launched in 1858 and was by far the biggest ship afloat. One of its designers was I. K. Brunel, that many consider as one of the greatest engineers of that era. With each project he expanded engineering technique beyond anything known or imagined (John Lienhard at University of Houston). I. K.

The first telegraph cable across the Atlantic The first big step in the laying of submarine cables, in essence a giant step considering the state science at the time. Understandably many thought this was impossible. This drawing is supposed to be from a meeting with Cyrus Field on the 8 th of May 1854 when the New York, Newfoundland and London Company was founded. Cyrus Field turned out to be the biggest driving force of this idea (project), even though much of the money, ships and all of the cable came from Britain. 7

About 40 years later the Icelanders isolation was finally ended: The first telegraph cable to Iceland came in 1906. 9 In 1904 an agreement was made with the Danes and the Great Northern Telegraph Company about a telegraph cable to Iceland and telephone line from Seyðisfjörður in the east of Iceland to Reykjavik. The cable would link Lerwik, Shetland Islands Torshavn, Faroe Islands and Seyðisfjörður, Iceland. It should formally open the 1st of October 1906. The cable came to shore at Seyðisfjörður on the 18th of August 1906.
Iceland connected to the wider world by telegraph cable 1906 The steamer Cambria, a specially built cable laying ship, that was used in laying the first communication cable to Iceland. The picture shows the ship at Lerwick, Shetland Islands in 1906. (Error in picture text.) 10
The development between 1906 ~ 1950 a short overview 1906 The first telegraph cable to Iceland. Telegraph service opened to abroad from Seyðisfjörður. Telephone and telegraph service service from there to Reykjavík. Landsími Íslands (the national telephone company) established. 1918 The wireless station in Reykjavik, Reykjavík radíó oftskeytastöðin í Reykjavík, Reykjavík radíó, established. Morse is used in all communications. 1929 The telephone system now finally a ring around the country. 1930 Telephone service to ships and boats through wireless MW (medium wave). 1932 The first automatic telephone exchanges in Iceland oprerational. 1935 Telephone service on wireless SW (short waves) to abroad opened. The telephone and postal service merged into one company: Póstur og Sími. 1938 A service to establish a connection between ships and a telepone user on land set up. 1946 Radio communications in service of international airplaine traffic started. Morse code is used. 111947 Telephony on SW to N-America. Partly from: www.simnet.is/ofeigur/simstodin.htm
Another landmark cable in 1956: TAT-1 the first telephone cable across the Atlantic. It was not possible to transmit voice across very long cables until it was possible to insert amplifiers regularly within the cable. (Consider bandwidth, attenuation and noise.) Even though the transistor had been invented in 1947, tubes were used as the amplifying element in the first telephone submarine cables. 12
The development in Iceland 1951 ~ 1986 a short overview 1951 Voice communications to aeroplanes. 1962 Scotice, a telephone cable between Iceland, Faroe Islands and Britain. 1963 Icecan, a telephone cable between Iceland, Greenland and Canada. 1966 The state television RÚV starts to broadcast in September that year. 1977 RÚV starts to broadcast in color! 1980 The earth station Skyggnir opened for service. Telephone connections to abroad now go through satellites. Users can dial directly to numbers abroad! 1984 The first digital telephone exchanges set up and eleven years later all the exchanges were digital. 1985 The laying of fiber optic cable around Iceland commences. 13 1987 All telephones in the country connected to an automatic telephone exchange. Masts carrying telephone cables have mostly dissapeared as the cables were put in the ground.

14 The first telephone cables to Iceland were connected in 1962 and 1963. SCOTICE, 1962 The old cable from 1906 failed on the 9th of January 1962 and was not used thereafter. SCOTICE became operational on the 22nd of January 1962 and offered initially 24 voice channels. ICECAN, 1963 As seen previously telephone connections to and from Iceland had been available on SW since 1935 (1947 to USA). Icelanders owned nothing in these cable systems, except the landing station for the cables in Vestmann Islands. To facilitate the laying of these cables, the Icelandic government made an agreement with The Great Nordic Telephone company, offering exclusive rights for telephone connections from Iceland for 25 years. Another vital element was an agreement with ICAO, as the number of flights across the North Atlantic were continually increasing.
15 Connections through SCOTICE og ICECAN I spite of these cables the telephone connection to abroad was not too secure. A number of incidents/failures were on these cables, especially in the beginning, both by fishing vessels and icebergs around Greenland. Sometimes both were down at the same time. Radio links were used as backup. But with these cables the cost of telephony to abroad was somewhat reduced and the use nearly doubled each year. Soon the number of channels on the cables were too few to meet demand. In 1973 a group was formed by the initiative of Póstur og Sími to explore the cost of a new cable between Iceland and Faroe Islands. Another group was also formed with the task of examine the cost of establishing earth station in Iceland capable of communicating through satellites. Results were available in 1974 and the latter option was considered more economical.
16 The connections to and from Iceland: The earth station, Skyggnir After some discussion with the Great Northern an agreement was made in 1977 on building an earth station and its ownership. (The Icelanders wanted most to own it themselves.) The earth station was formally operational on the 6th of October 1980. The station was given the name Skyggnir. Even though the number of telephone calls increased 100% in its first year of operation, for the first time the demand could be met. The ease of use was increased as the users could now dial directly to abroad and that was also cheaper than calling a human operator at the switchboard and have him/her place the call.
The development between 1986 ~ 1994 a short overview 1986 Connection to the Internet : When the Marine Institute connected to the European Unix network (Eunet). The connection was at first 300 bits per second and the Marine Institute and the University of Iceland were connected together. 1987 Research institutions establish a union, SURÍS. 1989 The running of SURÍS was moved from the Marine Institute to the computing department of the University of Iceland (RHÍ) and the international connectivity was moved to NORDUnet. NORDUnet is a joint collaboration by the Nordic National Research and Education Networks (NREN s): Forskningsnettet in Denmark, Funet in Finland, RHnet in Iceland, Uninett in Norway and SUNET in Sweden, and operates a world-class Nordic and International network and einfrastructure service for the Nordic research and educational community.

In 1994 the first optical cable connected to Iceland: The CANTAT-3 submarine optical cable 18 Canadian Transatlantic cable no. 3 - CANTAT-3
CANTAT-3 more info The length is about 7500 km Number of regenerators : 89 Regenerate the signal as it travels through the cable. This was the last cable across the Atlantic that used this technique, optical amplifiers and WDM were the next evolutunary steps for the optical fiber. Total capacity 5000 Mb/s = 5 Gb/s Operational in 1994 Owners: Teleglobe (An Indian company buys Telegleobe in the summer of 2005 *) Deutsche Bundespost British Telecom Telecom Denmark Síminn 19 *Videsh Sanchar Nigam Limited, VSNL. India's leading provider of international communications and Internet services." Now renamed to TATA Communications. Cables from around 1990
20 CANTAT-3 The connection to Iceland was to Vestmann Islands ( Heimaey ). Submarine optical fiber was layed from Westmann Islands to the mainland. To enhance the security a microwave link was also established between Heimaey and the mainland. A radar was also set up to follow the sea traffic around CANTAT-3.
The development between 1995 ~ 2004 a short overview 21 1995 All telephone centrals digital. Consequently some new services were offered. 1997 The company Post and telephone ( Póstur og sími hf. ) formally established as a limited company. 1998 Breiðbandið becomes operational. Telephone services seperated from the postal service. Landsími Íslands Inc. begins operation. Competition within telecommnunications opened up. TAL Inc. sets up a GSM a mobile telecommunication system. 1999 Internet in Iceland Inc. (Intis) increases its connection to USA to 45 Mb/s. 2000 New legislation on telecommunications come into force where each household ar should have at least 128 kb/s (ISDN) available. TETRA system becomes operational. Reykjavik Internet Exhange (RIX) established. 2001 The Icelandic research and educational network (RHnet) formally established the 24th of January. The University -_Hospital, several research institutions and all the universities in Reykjavík connected together with a ring connected fiber optic network with gigabit transmission capacity. a new fiber optic cable layed across the highland to Akureyri. 2003 Og Vodafone established through a merger from TAL Inc. and Íslandssíma Inc. New legislation on telecommunications come into force where there is no longer necessary to have a special licence to offer telecommunications services, but are now able to use general licences. 2004 Farice fiber optic cable formally opened on the third of February

The latest fiber optic cable to Iceland: Danice At the end of the summer of 2008 a new cable was destined for Iceland, this time from Denmark (Blaabjerg). It would use the same landing site as Greenland Connect on Landeyjarsandur. This new cable has four pairs. Each pair has 128 10Gb/s channels. The total capacity is therefore: 4x128x10Gb/s = 5120 Gb/s, or about 5,1 Tb/s (Tera = 10 12 ) The laying of the cable was not finished until in the summer 2009 and it was ready for service later that summer. 30 Picture from: www.invest.is/resources/images/invest.is/keysectors/kaplar.gif
