0 INTRODUCTION
TANGO55/i and TANGO56/i are designed for use on any GSM network in the world.
TANGO55/i and TANGO56/i are Tri-Band GSM/GPRS engines that work on three
frequencies GSM 900 MHz, DCS 1800 MHz and PCS 1900 MHz or 850 MHz, DCS 1800
MHz, PCS 1900 MHz, respectively. These full type approved integrated modems
constitute a self contained, fully integrated implementation of the GSM/GPRS.
TANGO55/i and TANGO56/i feature GPRS class B, class 10 (making download at
speeds up to 85 kbps) and support the GPRS coding schemes CS-1, CS-2, CS-3 and
CS-4.
TANGO55/i and TANGO56/i modems incorporate all you need to create high-
performance GSM/GPRS solutions; base band processor, power supply ASIC,
complete radio frequency circuit including a power amplifier, internal and external
SIM interfaces and an antenna interface as well.
The physical interface to the cellular application is made through a RS-232
connector. It consists of 9-pin RS232 interface, required for controlling the unit and
transferring data. They can be directly connected via RS232 interfaces to the serial
port of a desktop or notebook computer. Interfaces for audio signals and applying
power supply are also available.
The external dual band or triple band antenna can directly be connected to the
integrated 50 connector on the modem.
The TANGO55/56 are mobile stations for transmission of voice, data calls and FAX as
well as short messages (SMS - Short Message Service) in GSM Network.
To control the GSM module there is an advanced set of AT commands according to
GSM ETSI (European Telecommunications Standards Institute) 07.07 and 07.05
implemented.
About GPRS:
GPRS is standard for General Packet Radio 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.
When in regions where GPRS is not available, user can still access their important
information with GSM 14.4 kbps data connections.
Users are advised to quickly proceed to the “Security” chapter and read the hints
carefully.
0.1 The differences between TANGO55/i & TANGO56/i
modems
TANGO55 is a Tri-band GSM/GPRS device that operates on three frequencies
GSM 900 MHz, DCS 1800 MHz and PCS 1900 MHz, and is available to use
in the European and Asian Networks.
TANGO55i is also a Tri-band GSM/GPRS device that operates on three frequencies
GSM 900 MHz, DCS 1800 MHz and PCS 1900 MHz, and is available to use
in the European and Asia Networks. The TANGO55i modem provides a
specific software and hardware (internal TCP/IP stack software with
hardware extension) which has been internally implemented for using
the embedded TCP/IP stack software.

TANGO55/I & TANGO56/IVERSION 1.03
The integration of TCP/IP stack with hardware extension (a TCP/IP-
module added) into the equipment converts it to a stand-alone client
that can be connected to the internet via GPRS network. The modem
can also send and receive data by GSM (set into Command-Mode)
and GPRS network using TCP/IP stack. It supports SMS, DATA and FAX
calls. The TANGO55i modem can be easily controlled by using TCP and
AT commands. The “TCP Command Set” manual is also issued as
separate document and is available on the distributed CD for the
TANGO55i’s users.
TANGO56 is a Tri-band GSM/GPRS device that operates on three frequencies
GSM 900 MHz, DCS 1800 MHz and PCS 1900 MHz, and is available to use
in the European and Asia Networks.
TANGO56i is also a Tri-band GSM/GPRS device that operates on three frequencies
GSM 850 MHz, DCS 1800 MHz and PCS 1900 MHz, and is available to use
in the American Networks. However, the TANGO56i modem contains
1800 MHz GSM functions that is not operational (not allowed for use) in
U.S. Territories. This filing is only applicable for 850MHz GSM/1900 MHz
PCS operations, whereby only these frequencies (850MHz GSM/1900
MHz PCS) are possible to be used in U.S. Territories. The TANGO56i
modem provides a specific soft- and hardware (internal TCP/IP stack
software with hardware extension) which has been internally
implemented for using the embedded TCP/IP stack software.
The integration of TCP/IP stack with hardware extension (a
TCP/IP-module added) into the equipment converts it to a stand-alone
client that can be connected to the internet through any GSM
850/1800/1900 network. The modem can also send and receive data
by GSM (set into the Command-Mode) and GPRS network using TCP/IP
stack. It supports SMS, DATA and FAX calls. The TANGO56i modem can
be easily controlled by using TCP and AT commands. The “TCP
Command Set” manual is also issued as separate document and is
available on the distributed CD for the TANGO56i’s users.
Regarding the electrical interfaces, mechanical specification (dimension, form etc.)
and electrical specification are the same to all modems.
Please note that, according to your requirement you can choose the desired
device.
