When a Wi- Fi card is correctly installed, an option will appear on your desktop to let the adaptor search for a nearby connection (often, this is set to happen automatically when the computer is turned on). In order to give you online access, the Wi- Fi adaptor must be able to find a router or hub creating a Wi- Fi hot spot. Wi- Fi hotspots are areas where a local area network (LAN) is available, usually through a device that connects to the Internet via a cable and broadcasts the signal as radio waves.
If there is no wireless LAN near your desktop, you can easily create one by buying a router and turning your landline connection into a wireless network, although this is only useful if you have a second desktop or laptop computer. Wi- Fi hotspots are usually 3. When the Internet service is paid for and your desktop computer picks up a viable Wi- Fi signal, several things happen. First, the adaptor and the Wi- Fi hot spot must be able to communicate—there are several kinds of radio frequency formats Wi- Fi uses, known as a, b, g and n, and your adaptor must be able to read at least one of those. Most adaptors and networks broadcast in more than one format, so this is rarely a difficulty. Alternative Wireless Connectivity for Desktops. In addition to providing Internet access this way, desktops can also pick up several other types of wireless activity.
Certain phone companies, such as Sprint, offer a service that gives Internet access on their phone network, sending and receiving data through the same system they use to send voice information. This capability is available on 3. G networks, and can be given to your desktop if you buy a 3. G adaptor instead of a Wi- Fi adaptor. You must pay the phone company to use its 3. G network, but you can then access the Internet wherever the company offers phone service.
Wi. MAX is a service similar to Wi- Fi, but focuses on urban areas and a much wider broadcast range. Security and Data. Wi- Fi networks are protected from outside access by layers of encryption and passwords. Your adaptor sends packets of information back and forth from the Wi- Fi network with the correct password, and the network allows your computer to decrypt the data packets it sends.
Once the security qualifications have been met, the two devices can communicate effectively and begin sending large numbers of data packets back and forth, giving you access to web browsers, e- mail and other online applications on your desktop, just as an Ethernet connection would, often just as quickly, with only a few seconds of difference.
