Wireless modem setup 9 Wireless modem setup Important: This feature is available only if your service provider's network supports 1XRTT or circuit-switched data (CSD) digital data and fax services. A subscription to these services may also be necessary. Please check with your service provider for more details. Your phone can function as a wireless modem when connected to your PC. Once your phone is installed and configured properly, your phone works in conjunction with your existing data and fax software, allowing you to connect to a corporate network, the Internet, or check e-mail wherever you are. • LEARN ABOUT DIGITAL DATA Circuit Switched Data (CSD) Until now, your only wireless data option has been your service provider's Circuit Switched Data (CSD) network. Using CSD, you create a virtual circuit between your phone (as a wireless modem) and your Internet service provider (ISP), corporate network, or a fax machine. As long as a digital data or fax call is active, you are typically being billed for the air time (whether you are transmitting/receiving data or not). The fastest CSD data rate available is 14.4KBps. Quick Net Connect (QNC) A Quick Net Connect (QNC) digital data call allows you to connect to the Internet more quickly than a traditional CSD call. This is achieved because your wireless service provider supplies the local connection to the Internet (instead of your local ISP's dial-up number). Like CSD calls, you are typically being billed for the air time (whether you are transmitting/receiving data or not). The fastest QNC data rate available is 14.4KBps. 1XRTT/3G packet data 9 Your Nokia phone is the first in a new generation of phones to take advantage of a new higher-speed data protocol called 1XRTT (1X). The benefits to you include: • Higher data transfer rates - up to 153.6KBps over the wireless network. • Data on-demand - data is transferred only when requested and billing is based on the amount of data you transfer. 1X packet data services work much the same way as a PC connected to a corporate network. Information is sent in bursts or packets only when there is a request for information. Otherwise, the PC or phone remains in an idle state. Internet access using your wireless service provider Your wireless service provider now becomes your Internet service provider when you use your phone as a wireless modem and use 1XRTT packet data or QNC. You no longer have to configure your laptop computer or handheld device for connection to your normal ISP when you want to browse the Web or check your e-mail. Access corporate network/e-mail using a VPN Virtual Private Network (VPN) services provide an encrypted communications tunnel through the Internet, creating a secure connection between your PC and corporate network using a high-speed or broadband Internet connection. If you plan on using 2G or 3G packet data services to access your corporate network's e-mail system, Intranet, or LAN, your corporate network must have VPN services available. In addition, your network administrator must grant you permission to access the corporate network through the VPN. Additional software on your PC (or modification of your PC's current network settings) may also be required. For more information on VPN services, please contact your network administrator. Important: Some ISPs may not permit access to certain services from Internet connections outside of your ISP's domain, for example checking/sending e-mail or newsgroup access. Therefore you may not be able to use 2G or 3G packet data in conjunction with some of your home ISP's services. Please contact your ISP for more information on accessing their services from outside their domain. Determine type of data services to use Your phone supports all three types of data services. There are times when it may be advantageous or appropriate to use one type of data service over another. [ 23 ]
