Calculation of expense for local computer networks

Different concepts of local computer network technological scheme and its economic justification with some appropriate calculations have been shown in this article. In our article, we are using our proposed approach, which can be helpful for some different companies, which is engaging to projecting and cabling the local computer networks. With using of this presented approach, these companies or other specialists in this area will be able to optimize their own costs more than 40% from full costs, which are planned for structured cabling design in data centres, and apartment buildings for data or voice communications using various kinds of cables. Our approach based on some standard costs varieties for the structured cabling design, which can be recommended to using only half part from cable possibility (wired cable). Therefore, full number of conductors in wired cable with the help of addition devices (splitters) was been offered to use. At the same time, any main functional characteristics of this wired cable were not being changed. In additional, is not any necessary to changing or re-building the rooms, hall-way's, passages and other kind of premises with using our approach, because this approach suggested to directly modify communication channels near the computer devices.
