Wireless communication technologies have been developed using electromagnetic waves propagating in the air, in several frequency ranges. It is the case of e.g. Wi-Fi and FSO, whose importance and utilization have been increasing. Wi-Fi is a microwave based technology providing for versatility, mobility and favorable prices. The importance and utilization of Wi-Fi have been growing for complementing traditional wired networks. It has been used both in ad hoc mode and in infrastructure mode. In this case an access point, AP, permits communications of Wi-Fi devices with a wired based LAN through a switch/router.
