Terms: Coverage area: The space in which the wireless radio signals in one wireless LAN can effectively reach and be used to send and receive data between the WLAN’s APs and its clients. Shared bandwidth: A term referring to how some networks must share the right to send data by taking turns‚ which limits the total number of bits sent by all devices (the network’s total capacity). Wi-Fi: A term created by the Wi-Fi Alliance as part of its overall wireless LAN branding and marketing strategy; this term

Abstract Wireless technology can now be seen almost everywhere. This technology has recently become very popular‚ and with the convenience that comes with its use‚ it will probably be the most commonly used technology among computer networks in the near future. Unfortunately‚ new technology is always under fire when it comes to security‚ which is a topic that has now become more imperative and indispensable when dealing with transferring and storing sensitive computer information. The realm of wireless

-Anam Will Wi-Fi Replace Wired LANs? In life today‚ networking has become a large part of our lives. It is the fastest way to transport data‚ and it is accessible wherever you are in the world. These connections are called LANs. LAN (local area network) is a group of computers and other electronic devices that are connected via a communications line. The LAN’s I will talk about are wired and wireless LANS. Before wireless networking‚ everything was connected with wires. However‚ today
