Exploring Wireless Network tutorials

  • In today’s age business uses WLAN (Wireless LAN). Unlike wired LANs, wireless devices transmit and receive data using Radio Frequencies (RF) or infrared signals. This frequencies or signals are sent through an Access Point (AP).

 

WIRELESS NETWORK ADAPTOR

  • Most wireless network adaptor (NIC) and Wireless Access Point confirm to standard based on the IEEE 802.1 Specification.
