9 Configure your data and fax software
Before you can use your phone as a wireless modem with your data or fax software, there are a few things you need to know about
recent developments in the wireless data technology. Once you understand more about the different types of digital data and fax
services available to you, you can configure your data or fax software for the right type of service.
• INTRODUCTION TO 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). 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 GPRS
Your wireless service provider now becomes your Internet service provider when you use your phone as a wireless modem. 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.
Determine type of data services to use
Your phone is capable of functioning as a wireless modem for both types of data services. There are times when it may be
advantageous or appropriate to use one type of data service over another.
GPRS DATA
You 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 access
point, you don't have to search for your regular ISP's local dial-up number.
CIRCUIT SWITCHED DATA
You may need to use CSD when:
•
you need to send a fax to a machine connected to a traditional phone line
•
your corporate e-mail or ISP's e-mail system does not allow checking of e-mail from other Internet access points
•
your corporate network has not established a GPRS access point to allow secure access to their network from your wireless
service provider
Observe the following before making or receiving digital data or fax calls
•
You must subscribe to digital data and fax services with your service provider.
•
Your phone must be powered up, and you must be in a GSM1900 network. GPRS services must be available for GPRS data calls.
•
Your PC's infrared port must be configured properly (internal or external port).
•
You must establish an infrared connection between your PC and your phone.
•
Your data software must be running and configured to recognize your Nokia phone as the active modem.
