Working with GSM/HSDPA/UMTS/GPRS/EDGE

Overview

The Dolphin 9700 terminal can be configured with an integrated, embedded GSM/UMTS/GPRS/EDGE penta-band radio module for WWAN communication.

GSM

Short for Global System for Mobile communications, GSM is an open, non-proprietary wireless

 

WAN system that is constantly evolving and growing.

HSDPA

Short for High-Speed Download Packet Access, HSDPA is a non-voice value added service that

 

allows packet-switched data to be instantly sent and received across mobile telephone networks.

UMTS

Short for Universal Mobile Telecommunications System, UMTS is a non-voice value added service

 

that allows packet-switched data to be instantly sent and received across mobile telephone

 

networks.

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.

EDGE

E-GPRS is a non-voice value added service that allows packet-switched data to be instantly sent

 

and received across mobile telephone networks at a higher data rate than standard GPRS.

RequirementsUsing GSM/HSDPA/UMTS/GPRS/EDGE requires a:

•Network subscription to a GSM/HSDPA/UMTS/GPRS/EDGE 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 SIM Card Installation on page 9-2).

Penta Band Antenna

The GSM radio features an internal antenna that is optimized for power output and receiver sensitivity. This is an omni-directional antenna.

For the HC-25 radio, there is a unified penta-band antenna that supports 850/900/1800/1900 (GSM/ GPRS/EDGE) and 850/1900/2100 (HSDPA/UMTS) MHz for obtaining GSM service worldwide.

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.
