Wireless Network
Surf free from the constraints of cables
Wireless networking refers to the connection and communication between multiple computers that is accomplished without the use of wiring. Instead, communication is generally achieved through electromagnetic or radio waves.
Using wireless network cards or Ethernet adaptors, most devices can be configured to be part of your wireless home network. All devices in the network connect to a single access point, all with the same service set identifier. As well, because wireless networks make transmitted data more susceptible to electronic eavesdropping, a Wired Equivalent Privacy (WEP) key or other authentication method is used. Each device in the network shares the same key, thus enhancing wireless network security.
Wireless Internet connections can be made to a computer network through a wireless router, which also uses electromagnetic waves to send and receive data. A wireless card or USB adaptor is required for communication between the wireless routers and the computer.
Wireless protocols and standards are established by the Institute of Electrical and Electronics Engineers (IEEE), which set the standard at 802.11, though there are further specifications within this standard - the 802.11a, 802.11b and 802.11g protocols, also called Wireless-A, Wireless-B and Wireless-G respectively. Wireless-B is the most common protocol; it is more reliable and less expensive to produce and use than Wireless-A. Wireless-G, however, is increasing in popularity, as it is much faster than Wireless-B.
Must-Have Features
- Your wireless router should have a removable, range-extending antenna so that you can adjust your range when you need to.
- Security features like Wired Equivalent Privacy (WEP) and encryption are required to prevent electronic eavesdropping.
- A wireless adaptor or wireless network interface card in every desktop and laptop in the network.
Major Considerations
- Is a wireless network better than a wired network for my computer and Internet usage?
- What kind of wireless network best suits my needs?
- What IEEE standard should I use?
