WiFi Equipment For Your Home
A Wireless RouterThe first thing needed for a WiFi network, in most cases, is a wireless router. Many broadband companies now provide this piece of equipment when they set up your service. What the wireless router does is transmit the information that comes from your provider to the other computers in your network. It manages who gets what information and it is the device you configure to determine the SSID, which determines which computers can access your network.
A Wireless CardHowever, WiFi with just a transmitter isnít very useful. Unless your computer or laptop has built-in wireless devices, you will need some sort of wireless card. For PCs, this is usually a card that plugs into the PCI slot on your motherboard and has an antenna to aid in receiving data. If you have a laptop, itís probably built in, but can also be obtained by a wireless card that you plug into the PC Card slot. Alternately, there are wireless receivers that run through USB as well. With a wireless card to receive what your router sends, you have a basic WiFi network.
The Advantage Of WifiThe big benefit of WiFi over wireless networks, of course, is that with just a little equipment, you can connect several computers to your home network without running any wires. Even if you donít have a wireless router at home, for example, as long as you have a wireless card and permission to use an SSID, whether at a coffee shop that offers WiFi access or at a friendís house, you can have access to a computer network.
Because WiFi equipment is inexpensive, with cards available for under $50 nowadays, itís also a very affordable technology. If your broadband company provides the router, the startup costs of such a network is very low, giving you access to fast Internet access for research or online gaming anywhere in your home. With such an advantage, itís easy to see how having basic WiFi equipment can improve your home computing.
