Wi-Fi technology uses radio waves in order to produce wireless high-speed Internet connections. No physical wiring is required with Wi-Fi since it uses radio frequency technology. To use Wi-Fi, an access point must exist. This access point broadcasts a wireless signal that can be detected by other computers. Once a computer detects the signal, it can tune in provided the computer has the specified wireless network adapters.
Connecting wireless Internet to a desktop computer in addition to a laptop is certainly possible and even favorable so that you always have access. Typically, you need to have a router in order to allow more than one machine to have access to Internet. For Internet services accessed via satellite, wires do not even come into the picture.
However, if you plan to have more than one computer using the wireless Internet, each machine needs to have its own Wi-Fi card. You have two choices for your Wi-Fi cards- an external one or an internal one. An external Wi-Fi card is a device that the computer user inserts in an external slot on his machine in order to add Wi-Fi capability. Typical examples are CardBus, PCMCIA, USB, or Expresscard. These devices can be used on either laptops or desktops.
An internal Wi-Fi card is one that exists inside the laptop or desktop computer in order to add Wi-Fi capability. Some cards are preinstalled and come with the machine. In other cases, the Wi-Fi card can be inserted into the computer easily enough.
Wi-Fi cards allow computer users to tap into certain hot spots. Today, hot spots can be found all over the place as many businesses have signed on to provide public access to wireless high-speed Internet. A USB device can be installed to allow you to gain access to wireless Internet on the go wherever you are. In general, you need to be within a certain range or number of yards in order to access this service.
Shop around for prices and availability if you are interested in Internet on the go. Different plans and rates are featured by most of the major telephone companies. In fact, some of them even offer special deals for members of their phone services. I might also recommend that you try out this service before signing on for a year’s contract. In fact, AT & T offers a one-time connection at the moment for less than $4.00 for a 2-hour connection or twice that amount for a 24-hour connection. Why not sample what’s out there before you make the commitment?
