Popis: The paper approaches one of the most important technologies of the modern communications the Code Division Multiple Acces (CDMA), which has a huge influence on the actual mobile communications networks (3G, 4G) and beyond. The paper presents CDMA from a dual point of view, as a powerful technology for the most dynamic communications networks, cellphone broadband mobile communications, but on the other hand revealing that CDMA represents also one of the information and communications technologies (ICT) that could inluence people and their ways of thinking, as a model. Some interesting aspects covered by the paper present important moments and contributions in the spectacular evolution of CDMA, in USA, Romania and generally manifest in the World, as CDMA is an inherent feature of the spread-spectrum systems (SSS) of communications (first and long time used only for secure military communications) and both CDMA and SSS were very skeptical perceived by the civilian specialists and the industry, because they were long time considered too complicated for commercial use. One of the papers points stress the deep significance of the CDMA/SSS evolution, as a long fight against all the challenges, a process where the knowledge, the innovation and the passion were the main ingredients of the final succes a huge achievement for ICT and the information society (IS). One the same line, the papers conclusions refer to the power of CDMA to leverage the mankind activity, by technological concrete consequences and also as a model to manage the resources - from time and electromagnetic spectrum to anything people must share on Earth.
