Net+it works business began with mobile system solutions. Of course, in 1967 the number of companies that specialized in this field was extremely limited. There was another system using radio technology called fixed-type, or stationary, wireless communication. However, Net+it works specialised in mobile-wireless technology, which is only now starting to blossom. Then in the 1980s we began to turn our attention to building systems to respond to the digitalization of communication technology. As a part of that effort we added to our core competencies the integration of telecommunication systems. These formed the foundation of data transmission and of software development, in particular of Unix Operating System which was the defacto OS for communication software. At about the same time we added so-called open network solutions with the integration of Internet Protocol (IP) networks and computer networks. The development of these technologies requires much time and financial resources, but Net+it works set out steadily and with singleminded commitment to achieve an extremely high level of network solution capacity. Similarly, with the many leading edge technologies and new technical fields that will henceforth emerge, Net+it works will continue to strive resolutely to meet these challenges.
