This paper provides a detailed picture on computer networks and especially on wireless networks, focusing on specific characteristics of wireless systems. By using MIMO technology (Multiple Input Multiple Output), network logon can be realized at distances much greater. The use of antennas allows reception and transmission of multiple data streams simultaneously, and the router gives a much better quality of data transmission and added safety. For network security is available WEP encryption on 64 or 128 bits. Technology and wireless services now offered by manufacturers and retailers are moving quickly to satisfy all communication needs.
