Dolphin terminals can be configured with a Siemens

®

 GSM/GPRS quad-band radio module for Wireless WAN connectivity. 

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 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 network.

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 enabled. For more information, see 

Radio Manager

 on page 

4-5.

Dolphin 7900 terminals can support an MC-45, MC-46, or MC-75 radio. 

Supports 900/1800/1900 MHz frequencies for use in Europe, Middle East, Asia and Australia. 

 

Dolphin terminals with an MC-45 radio have two-way voice and data communication.

Supports 850/1800/1900 MHz frequencies for use in the U.S., Canada, and Latin America. 

 

Dolphin terminals with an MC-46 radio have two-way data communication only.

Supports 850/900/1800/1900 MHz frequencies for use in the U.S., Canada, Latin America, Europe, 
Middle East, Asia, and Australia. 

 

Dolphin terminals with an MC-75 radio have two-way voice and data communication .

Dolphin 7900 terminals configured with an MC-45 or  MC-46, or MC-75 radio feature an external antenna that is optimized for 
power output and receiver sensitivity. 

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 installed on the terminal (see 

.

Dolphin computers with integrated GSM/GPRS MC-45 radios are optimized for the following two-way voice and data 
communications:   

•           GSM voice data ("dial-up")
•           Short Message Service (SMS) text messages
•           GPRS Class 10 data transmissions average - 40-60 Kbps (The speed is dependent on the wireless network carrier.)
