Wireless networks are rapidly becoming more popular and coming down in price. Because they don't require cables, you can use the devices anywhere in an office or home, even out on the patio. There's no need to roll out an Ethernet network cable to each room of a house; you can network anywhere--without wires. Outside the home, wireless networking is available in hotspots at coffee shops, businesses, and airports--great when you're on the road and need to get some work done. For convenience, wireless networking is the answer.

Which Wireless Standard Is Right for Me?
Now that you've decided to create a wireless network, the next step is to figure out which wireless standard to use.

Basically, a standard is a set of specifications for a device. All devices that follow a specific standard share operating characteristics, such as the radio frequency used and maximum data transfer speed.

For wireless networking, there are three standards to choose from at this time:

• 802.11b
• 802.11a
• 802.11g
