Future deployments of 5G mobile telephone networks will bring large-scale small-cell roll-outs. A small cell is nothing more than a miniature base station, or low-powered mobile telephone node, that improves a network’s spectral efficiency by allowing the same frequencies to be reused within a geographic area thanks to its limited range (10 meters to a few kilometers).
Traditionally several current network scenarios are based on packet routing, but to reduce the network complexity, a concept has appeared on the market: session-based routing. This is due to theThe evolution of the network, which has reached a point where the complexity is continuously growing, and the elements involved are more and more expensive.
Nowadays, all offices, hotels, parks, hospitals and above all private domiciles, have Wi-Fi connectivity for laptops, tablets and smartphones. Likewise, we must consider the new lines of intelligent domestic equipment, also connected and remotely managed via Wi-Fi. There is, however, a question we all ask ourselves: how safe are wireless networks?
Payment Credit cards are now used world over and are more popular than ever. In Spain, for example, there are almost 50,000,000 cards in use (of different types). The latest generation of cards comes with Brand new technological components that increase security and help simplify operations.
Multiprocessing is the use, within the same system, of several CPUs that share resources among them. There are many kinds of multiprocessing systems and they vary according to different aspects. Their type will first depend on the location of the CPUs (i.e., whether they are on the same die, chip or on the same board).
