Radio Frequency Exposure - SAR 

 

The  Smart  SAM3T  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  SAM3T  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.
