Wireless Networks

Wireless networks use radio signals in place of wires to transmit the information among the devices on your network. Wireless is a relatively recent addition to the networking scene, but it has really taken off—especially in the home networking arena. .
Wireless networks offer several advantages compared to wired networks:
1.Installing wireless networks is easier than with wired networks, because you do not have to run cables.
2.Adding more PCs to a wireless network is easy.
3.Wireless networks give you the freedom to move to different locations within the range of the network with virtually no fuss or bother.
4.Wireless networks are rapidly becoming the most popular form of home networking, so the wireless network you set up today might have a longer useful lifetime than a wired network would.
Wireless networks do have some disadvantages, though:
1.The basic equipment required to set up a wireless network costs somewhat more than that for a simple wired network.
2.Wireless networks tend to be slower than wired networks.
3.Keeping a wireless network secure is somewhat more difficult than with a wired network.
4.Wireless networks can suffer from interference from numerous sources, such as microwave ovens and cordless phones.
5.Wireless networks might suffer from obstruction problems that severely restrict their operating distance.
