Configure your data and fax software[ 34 ]99 Configure your data and fax softwareBefore you can use your phone as a wireless modem with your data or fax software, there are a few things you need to know aboutrecent developments in the wireless data technology. Once you understand more about the different types of digital data and faxservices available to you, you can configure your data or fax software for the right type of service.• INTRODUCTION TO DIGITAL DATACircuit Switched Data (CSD)Until now, your only wireless data option has been your service provider’s Circuit Switched Data (CSD) network. Using CSD, youcreate a “virtual circuit” between your phone (as a wireless modem) and your Internet service provider (ISP), corporate network, ora 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/receivingdata or not). In addition, the fastest CSD data rate available is 14.4k bps.General Packet Radio Service (GPRS)Your Nokia phone is the first in a new generation of phones to take advantage of a new higher-speed data protocol called GPRS(General Packet Radio Service). The benefits to you include:• Higher data transfer rates - up to 40.2k bps over the wireless network.• Data on-demand - data is transferred only when requested. You pay only for the amount of data you transfer (vs. air time).GPRS data services work much the same way as a PC connected to a corporate network. Information is sent in “bursts” and“packets” only when there is a request for information. Otherwise, the PC or phone remains in an idle state.Internet access through your service provider using GPRSYour wireless service provider now becomes your Internet service provider when you use your phone as a wireless modem. You nolonger have to configure your laptop computer or handheld device for connection to your normal ISP when you want to browsethe Web or check your e-mail.Determine type of data services to useYour phone is capable of functioning as a wireless modem for both types of data services. There are times when it may beadvantageous or appropriate to use one type of data service over another.Access corporate network/e-mail using a VPNVirtual Private Network (VPN) service provides an encrypted communications “tunnel” through the Internet. It creates a secureconnection 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, yourcorporate network must have VPN services available. In addition, your network administrator must grant you permission to accessthe 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 informationon 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 (forexample: checking or sending e-mail, newsgroup access). Therefore you may not be able to use 2G or 3G packet data inconjunction with some of your home ISP’s services. Please contact your ISP for more information on accessing services fromoutside their domain.GPRS DATAYou may consider using GPRS data when:• you have large amounts of data to transfer and time/speed is a factor• you are traveling and want to surf the Web or check e-mail wirelessly. Because your service provider is your Internet accesspoint, you don’t have to search for your regular ISP’s local dial-up number.CIRCUIT SWITCHED DATAYou may need to use CSD when:• you need to send a fax to a machine connected to a traditional phone line• you do not have VPN access to your corporate LAN, Intranet, or e-mail system
