establish permitted levels of RF energy for the general population. The guidelines are based
on standards that were developed by independent scientific organizations through periodic and thorough
evaluation of scientific studies. The standards include a substantial safety margin designed to assure
the safety of all persons, regardless of age and health.
The exposure standard for Corporationdevices including mobile phones and Corporationmodems uses
a unit of measurement known as the Specific Absorption Rate, or SAR. Tests for SAR are conducted
using standard operating positions reviewed by the FCC with the device under test.
This device is to be used only for mobile and fixed applications. The antenna installation and
operating configurations of this transmitter, including any applicable source-based time-averaging duty
factor, antenna gain and cable loss must satisfy MPE categorical Exclusion Requirements of
§2.1091. The antenna(s) used for this transmitter must be installed to provide a separation distance of
at least 20 cm from all persons and must not be co-located or operating in conjunction with any other
antenna or transmitter.
transmitting at its highest certified power level in all frequency bands. Although the SAR is
determined at the highest certified power level, the actual SAR level of the phone or modem while
operating can be well below the maximum value. This is because the phone or modem is
designed to operate at multiple power levels so as to use only the power required to reach the network.
In general, the closer you are to a Corporationbase station antenna, the lower the power
output.
Before this device is made available for sale to the public, it must be tested and certified to the
FCC that it does not exceed the limit established by the government-adopted requirement for safe
exposure. The tests are performed in positions and locations (for example, at the ear or worn on
the body) as required by the FCC for each model.
In general, for the United States market, the embedded modules are treated as “mobile devices”
as per FCC CFR47 paragraph 2.1091. A mobile device is defined as “a transmitting device designed to
be used in other than fixed locations and to generally be used in such a way that a separation distance
of at least 20 cm is normally maintained between the transmitter’s radiating structure(s) and the body of
the user or nearby persons.” Manufactures of mobile devices may
be able to submit a Maximum Exposure Rate (MPE) calculation in order to demonstrate SAR
compliance.
