Advantages of wireless networking are its mobility and potential range. If you have a large enough antenna network, your network can stretch many miles. This would be an expensive network, but one that would easily break out of the brick and mortar confines of the office.
Wireless networking would also be a great advantage to college campuses to eliminate the need to tear through walls to install cabling because more and more students expect to have a network connection in their dorm rooms. Wireless networking cards are becoming more reasonable in price and can easily be issued to each student as he requires them.
Home networkers can also benefit from wireless networking. For those who cannot do wired network modifications to their homes, wireless networking removes the unsightly wires running along baseboards and ceilings that are required to connect computers in different rooms. With a wireless home network, you are not even confined to inside the house. Depending on the transmit power of your router, you can sit out in your backyard and watch clouds drifting by as you type away. Wireless routers are coming down in price with each passing day.
Choosing the right types of wireless devices is an important decision. The next sections discuss some of the basic differences between current protocols used for wireless networking.
