Wireless WAN (WWAN) Communications with GSM/GPRS
Note: The Dolphin 9500 is the only terminal in the Dolphin 9500 Series that can be configured with an integrated Siemens
®
GSM/GPRS tri-band radio module for WWAN communications.
Overview
Enabling the GSM/GPRS Radio
The radio driver for GSM is installed and enabled by default after each hard reset. Before using the radio, make sure that the
GSM radio is enabled. For details, see Using the Radio Manager on page 4-15.
Tri-Band Antenna
Dolphin terminals configured with a GSM/GPRS radio feature a tri-band antenna that supports 900, 1800 and 1900 MHz
frequencies for worldwide mobile applications.
Requirements
Using GMS/GPRS on a Dolphin terminal requires a:
• Network subscription to a GSM/GPRS network (you need to know what service providers are in your geographic area), and
• SIM card that has been activated by the network service provider installed on the terminal.
Capabilities
Dolphin terminals with integrated GSM/GPRS radios are optimized for the following two-way voice and data communications:
• GSM voice data ("dial-up")
• SMS (Short Message Service) text messages
• GPRS Class 10 - data transmissions average 40-60 Kbps (wireless network carrier dependent)
GSM Short for Global System for Mobile communications, GSM is an open, non-proprietary wireless WAN system
that is constantly evolving and growing. One of its great strengths is international roaming capability, which
provides standardized dialing in more than 170 countries.
GPRS Short for General Packet Radio Service, GPRS is a non-voice value added service that allows packet-
switched data to be instantly sent and received across mobile telephone networks.
