I65/I56I HARDWARE DESCRIPTION VERSION 1.00
0 Introduction
0.1 General
The I56/I56i is designed for use on any GSM network in the world. The
I56/I56i is a tri band GSM/GPRS engine that works on three frequencies
GSM 850 MHz, DCS 1800 MHz and PCS 1900 MHz.
This full type approved integrated modem constitutes a self contained, fully
integrated implementation of the GSM/GPRS. I56/I56i features GPRS class
B, class 10 (making download at speeds up to 85 kbps) and supports the
GPRS coding schemes CS-1, CS-2, CS-3 and CS-4.
The I56/I56i module incorporates 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 board-to-
board connector. It consists of 50 pins, required for controlling the unit,
transferring data and audio signals and providing power supply lines.
The external dual band or triple band antenna can directly be connected to
the integrated 50 connector on the side of module.
The I56/I56i is a mobile station for transmission of voice, data calls and
FAX as well as short messages (SMS - Short Message Service) in GSM
Network.
For battery powered applications, I56/I56i features a charging control which
can be used to charge a Li-Ion battery. The charging circuit must be
implemented external the module on your application platform.
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.

0.2 The difference between I56 and I56i modules
I56 The I56 is a Tri-band device which operates in three frequencies
GSM 850 MHz, DCS 1800 MHz and PCS 1900 MHz, and is
available to use in the American Networks. However, the I56
module contains 1800 MHz GSM functions that is not operational
(must not be used) 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.
I56i The I56i is also a Tri-band device which 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 I56i
module contains 1800 MHz GSM functions that is not operational
(must not be used) 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 I56i 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 I56i module comes without modification regarding to
the 50-pin board-to-board connector.
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 module can also send and receive data
by GSM and GPRS network using TCP/IP stack. It supports SMS,
DATA and FAX calls. The I56i module can be easily controlled by
using AT or TCP commands. The “TCP Command Set” manual is
also issued as separate document and is available on the distributed
CD for the I56i’s users.
Please note that, according to your requirement you can choose the desired
device.

IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF
YOUR GSM MODEM, READ THIS INFORMATION BEFORE USE!
Your cellular engine I56/I56i is one of the most exciting and innovative
electronic products ever developed. With it you can stay in contact with
your office, your home, emergency services and others, wherever service is
provided.
This chapter contains important information for the safe and reliable use of
the I56/I56i. Please read this chapter carefully before starting to use the
cellular engine I56/I56i.
1.1 General information
Your I56/I56i modem utilises the GSM standard for cellular technology.
GSM is a newer radio frequency („RF“) technology than the current FM
technology that has been used for radio communications for decades. The
GSM standard has been established for use in the European community and
elsewhere.
Your modem is actually a low power radio transmitter and receiver. It sends
out and receives radio frequency energy. When you use your modem, the
cellular system handling your calls controls both the radio frequency and the
power level of your cellular modem.
1.2 Exposure to RF energy
There has been some public concern about possible health effects of using
GSM modem. Although research on health effects from RF energy has
focused for many years on the current RF technology, scientists have begun
research regarding newer radio technologies, such as GSM. After existing
research had been reviewed, and after compliance to all applicable safety
standards had been tested, it has been concluded that the product is fit for
use.
If you are concerned about exposure to RF energy there are things you can
do to minimise exposure. Obviously, limiting the duration of your calls will
reduce your exposure to RF energy. In addition, you can reduce RF
exposure by operating your cellular modem efficiently by following the
guidelines below.
1.3 Efficient modem operation
In order to operate your modem at the lowest power level, consistent with
satisfactory call quality please take note of the following hints.
 If your modem has an extendible antenna, extend it fully. Some models
allow you to place a call with the antenna retracted. However, your
modem operates more efficiently with the antenna fully extended.
 Do not hold the antenna when the modem is „IN USE“. Holding the
antenna affects call quality and may cause the modem to operate at a
higher power level than needed.
