    Networks on networks

    Connecting entities through networks – in

    technological, societal and personal terms –

    enables telecommunication. Networks occur on

    different levels, form parts of larger networks,

    and exist in numerous varieties. The artist Odd

    Andersen visualises the networks on networks

    by drawing interconnected lines with different

    widths. Curved connections disturb the order

    and show that networks are not regular but are

    adapted to the communication needs.

    Telektronikk’s forerunner, TECHNICAL INFORMA- TION from the Telegraph Administration, appeared in April 1904, with the intention “to impart knowl- edge, to all personnel, of the State Telegraph Admin- istration technical installations, and to supply the more important news in the areas of telegraphic and telephonic technology.”

    This modest beginning took place at a time when telecommunications was dominated by the telegraph. Since the establishment of the Norwegian Telegraph Administration in 1855, the countrywide telegraph services had in 1904 grown to be a necessary instru- ment, a must, in all kinds of commercial activities. The telephone service was in its early youth; it existed mainly within the cities with poor coverage. Long distance telephone calls might be dispatched only on a few routes.

    Radio communications had hardly come to Norway. The first trials with radiotelegraphy had taken place in 1903 in the northern part of the country.

    There is a huge gap between the state of the art in 1904 and the technology of today and the wide port- folio of advanced services which are now being offered. In a number of short articles in this issue, Telektronikk’s editor, Per H. Lehne, gives an overview of the technology and how some events have been reflected in the journal. In all the years after the introduction of the journal idealistic engi- neers and technologists have presented information about innovations in telecom with emphasis on appli- cations in Norway. In older issues you will find pre- sentations about the bigger paradigm shifts in tech- nology and new technical installations in the network. The journal has in that way kept up with the original idea to update the personnel in the technical field. Looking back in the old volumes a historian may find detailed information about the first long distance net- work made up of open-wire lines on poles, the devel- opment in telephony, the manual systems, conversion to automatic systems, automation of the long distance network, the introduction – and the end – of the telex network, the large scale deployment of micro wave systems in the trunk network, satellite communica- tion systems, introduction of fibre technology, and not to forget the digitalisation of the telecom network.

    In 1967 the Research Institute was established as part of the Telegraph Administration and opened for an

    influx of young and ambitious researchers, which led to a new keenness in all professional operations of the company. A natural development was that this new personnel category gradually left their mark on the journal and raised the quality of the content. Further- more, the journal could also serve as a channel to external readers, within and outside the country, and might thus promote the company as a modern techno- logical enterprise. As a consequence articles written in English appeared in the journal.

    The objective of promoting the company was even more emphasized when the state enterprise in 1994 was converted to the private company Telenor (although fully state owned) and later introduced to the stock exchange. A new editorial policy was intro- duced for the journal, with more systematic selection of topics for each issue, aiming at readers both at home and abroad. As a consequence, it was decided that Telektronikk should have full production in English.

    So, what is ahead? A leading engineer and later Director of the Telegraph Administration, Sverre Rynning Tønnesen, formulated his vision for the tele- phone service in the 1930s as: “Anyone, located any- where, should at any time easily get access to a tele- phone, and be able to establish a telephone call with good quality to any other person, located anywhere in the world.”

    Certainly, it can be said that this vision is a reality today. But this is not the end of the development and the demands from the users. Mobile communication has revolutionized the possibility for any person to be accessible at any time and wherever the person might be, not only for telephone conversations, but also for all other kinds of communication which may be real- ized face-to-face. The demand for portability and higher capacity is increasing and must be expected to increase furthermore in the years to come, as a pre- requisite to realizing new and enhanced services. While fixed-line technology generally offers higher capacity than mobile communication, mobile offers portability. You can easily predict that much creative research may be invested in efforts to bridge this kind of gap between the two technologies.

    The modern society of today depends on efficient and reliable telecommunications services to enable busi- ness operations and public services to society. Over
