Abstract:In this paper, the part of multicriteria analysis of road knowledge innovation in ICT subfields are segregated and grouped according to the international classification standards (ICS). Correlations between innovation and standardization of communications, local area networks (ICS-2 = 35.110), the global communications and the internet (ICS-2 = 35.100) are presented. Presentation of research innovation sources of knowledge are based on the result of years of study. Results from the overall population of creativity with over 72.340 standardized knowledge sources (ISO standards and SRPS) are segregated for these standardized subfields. Clustering, PDCA methodology (Plan-Do-Check-Act) and other research methods are applied. The focus is on the subfields of the highest intensity of innovation. There are original results: trend analysis, original dimensions, quantity indices, indices of setting values, indices of innovation knowledge resources, etc. The results indicate a correlation of standardization and innovation in the time dimension of the concept of PDCA.
CARRD.NET enables quick and easy design of point-to-point (PP) and passive repeaters microwave networks by simply entering the site coordinates; geographic distribution of radio stations, output powers, antenna radiation patterns, filter suppression of neighboring channels and receiver thresholds as well as the repeaters details; and coordinates for each link into a simple set of forms. The paper gives detailed description of module for calculation of interference in the network with a special consideration for the role of passive reflectors, by whose increase the network jamming increases exponentially. Besides, the CARRD.NET is realized as GIS software so that it can be used for both maintenance and radio-relay networks extension.Keywordsinterference, GIS software, passive repeater, planning of radio-relay networks I. INTRODUCTIONExpansion of Internet and mobile telephony has created a need for high-density radio-relay networks because of their low price and quick installation. The needs for new applications and ever denser networks have caused interference problems i.e. a more careful choice of sub bands, channels and antenna polarization. The limiting factors in solving of this problem are the number of available channels and the costs. In order to minimize frequency dependent spare parts such are oscillators, diplexers and sometimes the whole microwave blocks, it is beneficial to use the same channels as often as possible. Majority of radio-relay equipment producers fabricate devices that cover bands from 28MHz to 56MHz, which means 4 to 8 channels when it comes to small or medium capacities [1][2][3], i.e. one channel when it comes to high capacity. This problem is additionally complicated by the fact that high capacity devices are much more expensive than the others. Petar Joanovic, is with the
