3Safety Precautions
The following safety precautions must be observed whenever the Smart SAM3W modem is in operation or in
service. Failure to comply with these precautions violates the safety standards of the design, manufacture
and intended use of the product
- Switch off the Smart SAM3W modem :
In hospitals or places where medical equipments may be in use.
In an aircraft
Refuelling points
Explosive areas
- Restricted use of the Smart SAM3W modem
Near any chemical plant
Near any Fuel depot
Areas with mobile phone warning signs
Respect national regulations on the use of cellular devices. Road safety always comes first
The Smart SAM3W modem receives and transmit radio frequency energy while switched on, therefore
interference can occur if the Smart SAM3W is near TVs, radios, PCs or any inadequately shielded
equipment.

4Radio Frequency Exposure - SAR
The Smart SAM3W modem is a low-power transceiver, similar to a typical handheld GSM/GPRS/UMTS
mobile phone. When it is turned on, it will emit low-level radio frequency energy.
There are different guidelines and standards around the world that govern the permitted levels of radio
frequency exposure for general population. The levels include a safety margin to a human body.
The Specific Absorption rate (SAR) is a measure of the rate at which radio frequency energy is absorbed by
the body when exposed to radio frequency electromagnetic field. The SAR value is determined at the highest
certified power level in the laboratory conditions, but the actual SAR level of the transceiver while operating
can be well below this value. This is because the transceiver is designed to use minimum power to connect
to the network.
The Smart SAM3W modem is approved to use in applications where the antenna is placed more than
21cm from the body.
For other applications, the integrator is responsible for the local SAR requirements.

9Smart SAM3W TCP/IP Operation
When the STD-Link is closed, the modem acts as a standard modem, with the default terminal speed is
115200bps, data format is 1+8+1.
When the STD link is open, the TCP/IP stack is activated as described below.
9.1 The TCP/IP Stack Description
The Smart SAM3W TCP/IP stack allows the Smart SAM3W modem to act either as a standard 3G modem
(SAMMODE=0) or as a smart 3G modem. With the SAMMODE=1 or 2 the TCP/IP stack will take full control
of the Smart SAM3W and stay in GSM mode when SAMMODE=2 to allows the modem to receive GSM data
call (CSD) or automatically connect to PSD network when SAMMODE=1. Both UDP and TCP are supported,
the modem can work as a TCP client (making TCP connection) or as an TCP server (listen for TCP
connection), remote AT commands are supported on both CSD and PSD, all communications parameters
are store in FLASH can be programmed remotely over CSD, PSD or SMS, on power up the software reads
all parameters from FLASH and activates a GPSR connection, it then create an UDP and a TCP socket for
data transfer, an UDP and a TCP socket for remote AT commands, if programmed as TCP client it will try to
connect to a remote TCP server, the modem then stay in GPRS online idle state waiting for CSD call, SMS,
UDP data or TCP connection, the software maintain GPRS connectivity by the mean of IP TRACE using the
poll period programmed in FLASH. The TCP/IP stack can be update locally over the serial port or remotely
over GPRS or CSD.
9.2 Communication Sockets
TCP Data: Socket connection allows transparent data to pass through from host computer to the modem
serial port and vice versa, this operation is similar to the GSM data communication, in TCP
server mode the socket will be disconnected after 5 minutes of no data transfer.
UDP Data: Socket connection allows transparent data to pass through from host computer to the modem
serial port and vice versa, this operation is similar to the GSM data communication, a block
of data received from a remote UDP server will open a 2 minutes window for data to be
transfer from the serial port.
TCP AT Command: Socket connection allows a user from the host computer to send AT commands to
the modem and receive its responses, socket will be disconnected after 5 minutes of no
activity, and socket also can be used for remote firmware update.
UDP AT Command: Socket connection allows a user from the host computer to send AT commands to
the modem and receive its responses; socket also can be used for remote firmware update.
