This article is devoted to the analysis of operator strategies during frequency spectrum auction conduction. The strategic factors which are taken into account by the operators when making a decision about spectrum range buying are considered.
It is often possible to hear about "unlicensed LTE". It is told about unlicensed spectrum in the LTE networks. In this context different terms are applied LTE-U, LAA-LTE, LWA and others.
Nowadays amount of Big Data grows year by year. Increase in data array leads to emer- gence of new data processing technologies. Modern Big Data processing technologies have to solve 3 key problems: big data array storage, disparate data structuring, fast and accurate analysis.
At the present time published a number of papers that explore the issues of assessing the reliability of standard topologies networks (bus, ring, star), whereas data recovery tools of topologies have not been studied enough.
According to the theory, Fresnel's zones of a different order differently influence a signal on the route of its distribution. The signals passing at the same time through odd and even zones in a point of reception are opposite on a phase.
