Abstract:

Wireless networks have become an indispensable element of the space that surrounds us. There are several reasons why wireless networks have crept into the favor of today's engineers. The first is the ease of adding another device to an existing network. In the case of wired networks, if this network has been planned for a specific number of devices, and after some time we are going to add one or more devices, we need to build a piece of physical infrastructure to be able to do it. In some cases it is very complicated. For example, in industrial spaces, it is impossible to lay new infrastructure without taking into account the existing one. The wires can not go in any way and the logic cabinets have to be placed in very strictly defined places. Sometimes the expansion operation turns out to be impossible and a rebuilding, not just an extension, is necessary. In the case of a wireless network, the physical infrastructure does not exist, so it does not cause any problems.
