Working with GSM
Overview
The Dolphin 7600 can be configured with an integrated, embedded GSM/GPRS EDGE quad-band radio
module for WWAN communication.
Requirements
Using GSM/GPRS requires a:
•
Network subscription to a GSM/GPRS network (you need to know what service providers are in your
geographic area), and
•
An installed SIM card that has been activated by the network service provider (see

output and receiver sensitivity. This is an omni-directional antenna with zero dBm gain.
There are two different antennas based on geographical location; each supports two bandwidths:
Europe:
Supports 900 MHz and 1800 MHz bands.
North America:
Supports 850 MHz and 1900 MHz bands.
Signal Strength
The signal strength of the GSM connection is indicated by the number of bars that appear in the signal
strength icon in the Navigation bar at the top of the window.
Voice and Data Communication
Dolphin terminals with integrated GSM/GPRS radios are optimized for the following two-way voice and
data communications:
Voice:
GSM voice data ("dial-up")
GSM
Short for Global System for Mobile communications, GSM is an open, non-proprietary wireless
WAN system that is constantly evolving and growing.
