How Wireless Internet Cards Work

Understanding how a wireless internet card connects you to the internet will allow you to better maximize its potential. Before you are able to understand the mechanical workings of an internet card, it’s a good idea to know how wireless internet works in the first place. The functioning of wireless internet is very similar to the technology that drives radios and cellphones – capitalizing on radio waves; however, it still remains different from a digital subscriber line, or DSL, which transmits data through a phone line. When using a Wi-Fi hotspot, data is transferred through a wireless router. This particular router is connected to a plain old phone line, and has the ability to convert data in a binary format into radio waves. In order for certain devices such as laptops, some desktops and even PDAs to work with that data, they require a wireless internet card. This type of peripheral translates the detected radio waves from the router back into a binary format that the wireless device is able to understand. The entire process is then reversed when sending data back to the router from the device.

By taking a trip to the local computer sales or service shop, you should be able to find a variety of different network adapters. Some computer devices will even come with these cards, while others need to have them installed. The mini PCI and the PCI wireless adapter card are both the most popular forms of wireless internet cards available. The mini PCI is most commonly used in laptops, while the other is designed for desktops. In some cases you can obtain a USB network card, which tends to be far more convenient than the PCI wireless adapter cards, which generally require a little more hardware work during the entire installation process.
