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. In this sense, physical devices are only present in the transmitters and receivers of the signal, among which we find: antennas , laptops , PDAs , mobile phones , etc.           

Wireless network

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.
