Radio Frequency Exposure - SAR
The SAM3Gplus 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 SAM3Gplus 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.
