Wireless WAN Communications with GSM/GPRS

Overview

Dolphin 9500 terminals can be configured with Wireless Wide Area Network (WWAN) via an integrated Siemens
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
