Dolphin® 9500 Series Mobile Computer User’s Guide 9 - 1

Wireless WAN Communications with GSM/GPRS
Overview
Dolphin 9500 terminals can be configured with Wireless Wide Area Network (WWAN) via an integrated Siemens
®
GSM/GPRS
tri-band radio module.
Note: Dolphin 9550 mobile computers with pistol-grip do NOT support GSM/GPRS.
GSM - GSM stands for Global System for Mobile communications. It is an open, non-proprietary wireless wide area networking
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 - GPRS stands for General Packet Radio Service. It is a non-voice value added service that allows packet switched data
and information to be instantly sent and received across a mobile telephone network.
Powering Up the GSM/GPRS Radio Driver
When the mobile computer is first initialized, the radio driver for the GSM module is installed. Before using the radio, make sure
that the GSM radio is powered up. For more information,
see The Radio Manager on page 4-18.
Tri-Band Antenna
Requirements
Using GMS/GPRS on a Dolphin 9500 terminal requires:
a network subscription to a GSM/GPRS network (you need to know what service providers are in your geographic area), and
a SIM card that has been activated by the network service provider installed on the terminal.
Capabilities
Dolphin 9500 computers with integrated GSM/GPRS WWAN 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)
