house. Devices based on the 802.11 standards can connect to this network.
Your computer comes with a built-in wireless network card and a configuration utility to help you make
wireless connections and monitor the status of your connection, so that you can stay connected to your
network while you are in the office, in a meeting room, or at home, with no need for a wired connection.
Wireless WAN
Wireless Wide Area Network (wireless WAN), using cellular networks for data transmission, enables you
to establish wireless connections over remote public or private networks. These connections can be
maintained over a large geographical area, such as a city or an entire country, by use of multiple antenna
sites or satellite systems maintained by wireless service providers.
Note: Wireless WAN service is provided by authorized service providers in some countries.
