The  wireless communication
The  wireless communication  or wireless is one in which the  communication ( transmitter / receiver ) is not attached by a propagation medium physical, but the used modulation of electromagnetic waves through space.

The term  wireless network  (in English: wireless network) is used in computer science to designate the connection of nodes that occurs through electromagnetic waves, without the need for a   wired or wired network . Transmission and reception are done through ports
History of the Wireless Network
Wireless communication, which is carried out through radio frequency waves  , facilitates operation in places where the computer is not in a fixed location (warehouses, multi-storey offices, etc.) is currently used in a general and accessible way to all public. It should also be mentioned that wired networks have an advantage in terms of data transmission over wireless networks.
