Working with the mesh of network cables is somehow annoying. You have to organize the network cables to connect with your PC at home or at office. To avoid such a mesh of cables you need a wireless network. In this way you can work on your PC from anywhere through that wireless connection.

Such a wireless connection is also called as “WiFi connection”.

WiFi technology is another way of connecting your computer to the network using radio frequency and no network cables.

Wireless works similarly to cordless phones; they transmit data from one point to another through radio signals. But wireless technology also requires that you be within the wireless network range area to be able to connect your computer. There are three different types of wireless networks:

·         Wireless Local Area Network (WLAN): WLAN are wireless networks that use radio waves. The backbone network usually uses cables, with one or more wireless access points connecting the wireless users to the wired network. The range of a WLAN can be anywhere from a single room to an entire campus.

·         Wireless Personal Area Network (WPAN): WPANs are short-range networks that use Bluetooth technology. They are commonly used to interconnect compatible devices near a central location, such as a desk. A WPAN has a typical range of about 30 feet.

·         Wireless Wide Area Networks (WWAN): WWANs are created through the use of mobile phone signals typically provided and maintained by specific mobile phone (cellular) service providers. WWANs can provide a way to stay connected even when away from other forms of network access. Also, be aware that additional charges are often associated with the usage of WWANs in some locations.

How to Connect to a Wireless Network

If you have a laptop, you can see a list of available wireless networks, and then connect to one of those networks, no matter where you are. The wireless networks appear only if your computer has a wireless network adapter and driver installed and the adapter is enabled.

1.       Open Connect to a Network by clicking the network icon in the notification area shown below:

2.       In the list of available wireless networks, click a network, and then click Connect.

Some networks require a network security key or passphrase. To connect to one of those networks, ask your network administrator or Internet service provider (ISP) for the security key or passphrase.
