DANGER
Your computer has an Ethernet connector. To avoid the risk of electrical shock, do not connect
the telephone cable to the Ethernet connector.
Wireless connections
Wireless communication is the transfer of data without the use of cables but by means of radio waves only.
Depending on the wireless device used in your computer, you might be able to connect to the following
categories of wireless networks.
Wireless LAN
A wireless LAN covers a relatively small geographic area, such as an ofce building or a 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 conguration utility to help you make
wireless connections and monitor the status of your connection. This enables you to stay connected to your
network while you are at the ofce, in a meeting room, or at home, with no need for a wired connection.
Tips for using the wireless LAN feature
To achieve the best connection, use the following guidelines:
• Place your computer so that there are as few obstacles as possible between the wireless LAN access
point and the computer.
• Open your computer display to an angle of slightly more than 90 degrees.
• If you use the wireless feature (the 802.11 standards) of your computer simultaneously with a Bluetooth
option, the data transmission speed can be delayed and the performance of the wireless feature can be
degraded.
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.
Some ThinkPad notebook computers come with a built-in wireless WAN card integrated with some wireless
WAN technologies, such as 1xEV-DO, HSPA, 3G, GPRS, or LTE. By using the built-in wireless WAN card and
the conguration utility that comes with your computer, you can establish wireless WAN connections and
monitor the status of your connection.
Note: Wireless WAN service is provided by authorized service providers in some countries.
