GPRS

General Packet Radio Service (GPRS) is an enhancement to the GSM mobile communications system that supports transmission of data packets. GPRS is capable of running at speeds up to 115 kilobits per second and enables continuous flows of IP data packets over the system. Current GSM systems are capable of running only 9.6 kilobits per second.

GPRS makes efficient use of limited bandwidth and is especially suitable for sending and receiving data, whether in small bursts like e-mail and web browsing or large volumes like file transfers. GPRS technology offers broad high-speed connectivity and access Internet-based content, e-mail messages, and text messaging.

EDGE

EDGE is an enhancement to GPRS technology that enables higher speed data connections up to 384 kilobits per second. EDGE provides faster phone multimedia capabilities, like sending and receiving SMS/MMS messages and sharing video clips. EDGE is rapidly becoming a global standard for wireless wide-area data communication.

Users’ individual service providers may or may not support EDGE technology. If the user’s service provider does not support the EDGE network, the HP iPAQ automatically switches to GPRS data transfer rates, providing a seamless mobile experience and widespread access to Internet-based content and data services worldwide.

Notes

HP iPAQ devices are equipped to allow users to take advantage of GSM/GPRS/EDGE technology. However, users must arrange for GSM/GPRS/EDGE services separately with service providers. Service providers can supply information about availability and coverage in particular areas. Data transmission and download speeds may vary based up on network capabilities and other conditions. GPRS/EDGE data services may be subject to an additional charge beyond standard GSM mobile phone service.

HP iPAQ GSM/GPRS/EDGE Phone and Data Connection

GSM/GPRS/EDGE technology offers users more than the ability to make and receive telephone calls. HP iPAQ devices offer a comprehensive set of wireless capabilities to keep users connected in or out of the office. With GSM/GPRS/EDGE integrated into a single HP iPAQ, users have broad coverage offering high speed access to the Internet as well as business and personal information.

HP iPAQ devices offer the following connectivity options:

•Use the integrated GPRS/EDGE technology to connect to a Virtual Private Network (VPN) or to remotely connect to a mobile Internet Service Provider (ISP).

•Make a wireless GSM/GPRS/EDGE connection to place a phone call, send or receive e-mail or send SMS/MMS messages.

To send or receive data over a GSM/GPRS/EDGE network, users must have an account with a mobile phone service provider that supports GSM/GPRS/EDGE data services and an activated SIM card. The following features are supported on HP iPAQ devices but must be activated by users’ individual mobile phone service providers:

•Call forwarding

•CSD—Circuit Switched Data
