Connecting to the network Your computer has one or more network cards for connecting to the Internet and to your company's wired LAN or wireless LAN network. Note: Some models come with a built-in wireless WAN card enabling you to establish wireless connections over remote public or private networks. The Access Connections program is a connectivity assistant program for creating and managing location profiles. Each location profile stores all the network and Internet configuration settings needed for connecting to a network infrastructure from a specific location such as a home or an office. Ethernet connections You can connect to your network or a broadband connection, such as DSL or CATV, by use of the Ethernet feature built into your computer. This feature enables you to do 1Gbps half or full duplex data transmission. To connect to a network through Ethernet, you can use the Access Connections program. 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 connection is the transfer of data without the use of cables by means of radio waves only. Depending on the frequency used for data transmission, the area covered, or the type of the device used for data transfer, the following categories of wireless networks might be available to you. Wireless LAN A wireless LAN covers a relatively small geographic area, such as an office building or a house. Devices based on the 802.11 standards can connect to this network. Wireless WAN A wireless WAN covers a broader geographic area. Cellular networks are used for data transmission, and access is provided by a wireless service carrier. Bluetooth Bluetooth is one of a number of technologies used to create a wireless personal area network. Bluetooth can connect devices a short distance from one another, and is commonly used for connecting peripheral devices to a computer, transferring data between hand-held devices and a personal computer, or remotely controlling and communicating with devices such as mobile phones. WiMAX This long-range wireless data transmission technology based on the 802.16 standard is expected to provide the user a "last mile" broadband connectivity similar to that provided by cable or ADSL, but without the need to physically connect a cable to the personal computer. 32 User Guide
