Wireless Ethernet speed and frequency

Wireless Ethernet is available at two different speeds and at two different frequencies. The

following table compares the various wireless Ethernet network types.

Important If your computer came equipped with an internal radio frequency

wireless device, see “Safety, Regulatory, and Legal Information” in

your user’s guide for general wireless regulatory and safety

guidelines. To find out if your computer has an internal wireless

device, check the device manager. For more information, see

“Determining if wireless Ethernet is already installed on your

computers” on page91.

Important Note any antenna placement constraints in the user guide of each

type of wireless device in your network.

Network Type Speed Frequency Advantages Disadvantages

IEEE 802.11a 54 Mbps 5 GHz Less possible

interference than
