Using a wireless Ethernet network
A wireless Ethernet network is ideal for creating a home or office network or
adding mobility to an existing wired Ethernet network. A wireless Ethernet
network allows you the freedom to move about your home or office with your
notebook or tablet PC. For example, you can take your notebook or tablet PC
from your home office to your patio without having an Ethernet jack available.
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.
