0 INTRODUCTION

0.1 General

This manual is focussed on the GSM/GPRS/EDGE data solutions of the enhanced
performance SAMBA 75 USB modem from FALCOM GmbH.
The SAMBA 75 is a Plug-and-Play, compact, light-weight, wireless modem that
provides EDGE, GPRS and GSM connectivity for portable, handheld computers and
others. The SAMBA 75 maintains the same form-factor of the well-known SAMBA
GSM/GPRS modem. The major benefit over earlier SAMBA GSM/GPRS modem is that
SAMBA 75 supports EDGE and additionally offers a TCP/IP stack. The SAMBA 75
modem is designed to place and receive data calls but not voice calls.
SAMBA 75 allows subscribers to send and receive data, including digital images, web
pages and photographs, with a transfer rate three times higher than possible with
GSM/GPRS sevices. It supports Data, SMS, fax as well as it offers a choice of seven
different ringing tones/melodies, which are easily selectable using AT command. It
can be easily controlled by using AT commands for all kinds of operations. The
SAMBA 75 is designed for use on any GSM network in the world, it is a Quad-Band
EDGE and GSM/GPRS engine that works on the four frequencies GSM 850, GSM 900,
DCS 1800 MHz and PCS 1900 MHz and it can be used in all existing GSM networks in
Europe, the U.S.A. and Asia. This full type approved integrated modem constitutes a
self contained, fully integrated implementation of the GSM/GPRS and EDGE
functionalities. The SAMBA 75 provides an integrated SIM card reader and an
internal GSM antenna.
The physical interface to the modem application is made through an embedded
USB connector. It consists of 4 pins, required for controlling the unit, transferring data
and providing power supply lines. The embedded USB interface allows it direct
connection to a USB serial port of desktop or notebook computers. The SAMBA 75
features GPRS multi-slot class 12 and supports the GPRS coding schemes CS-1, CS-2,
CS-3 and CS-4. The SAMBA 75 equipment supports GPRS Class-B. This means, that the
Mobile Station can set up a GSM call (CSD or fax) while it is GPRS attached.
The SAMBA 75 features EDGE multi-slot class 10 and supports the modulation and
coding schemes MCS-1 ... MCS-9.
About GPRS
GPRS is a high-speed, data-only service that is an add-on to the GSM
(Global System for Mobile Communications) cellular network - a type of
network used to provide cellular phone service.
The SAMBA 75 Modem provides reliable data connections to GPRS 850 MHz
(GSM), GPRS 850 (GSM), 1800 MHz (DCS) and 1900 MHz (PCS) networks.
When in regions where GPRS is not available, user can still establish 14.4
kbps GSM data connections.
About EDGE
Enhanced Data rates for GSM Evolution (EDGE) is a third-generation (3G)
high-speed mobile data and Internet access technology, with theoretical
peak rates of 473 kbps and average throughput of 110-130 kbps. The
average rates are fast enough to support a wide range of advanced data
services, including streaming audio and video, fast Internet access and
large file downloads.
