About Wireless LANs.
About Wireless LANs A-1 About Wir eless LANs Wireless LANs are a revolutionary way of connecting devices to each other . In a wireless LAN, information is transmitted using r adio waves. This means that you can establish a network of wireless devi ces in a room or across different rooms without linking the devices with wires and cables.
About Wireless LANs A-2 About Ad-Hoc Mode Ad-hoc mode allows for wireless-to-wir eless communication. Wireless clients connected in this way can share files, prin ters, driv es and other resources, as well as access the Internet using a shared mode m.
About Wireless LANs A-3 About Infrastructur e Mode In Infrastructure mode, a wireless cl ient communicates with other wired and wireless clients through an AP router . A wi reless client connected in this wa y can access resources of Ethernet or wireless LA Ns connected to the AP router , including access to the Internet using a shared modem.
About Wireless LANs A-4 Setting Up Wir eless LANs When setting up a wireless LAN, ta ke note of the following points: ❑ Start by determining the areas to be networ ked, the number of users and the type of devices to be used. Then determine if you re quire AP routers and where they should be placed.
