Introduction:
A section explaining RF exposure requirements for integrating the RIM units into other
products should be added to the Integrator’s Guide. A draft of this section is included
here.

For portable devices, defined in accordance with FCC rules as a transmitting device
designed to be used within 20 cm of the user body under normal operating conditions, RF
evaluation must be based on Specific Absorption Rate (SAR) limits in Watts/kg. SAR is
a measurement of the rate of energy absorption per unit mass of body tissue.

For mobile devices, defined as a transmitting device designed to be generally used such
that a separation distance of at least 20 cm is maintained between the body of the user and
the transmitting radiated structure, the human exposure to RF radiation can be evaluated
in terms of Maximum Permissible Exposure (MPE) limits for field strength or power
density in mWatts/cm

RIM will submit module specific information and test reports for a generic MPE
compliance. For an end product not covered by RIM testing and submission, the
integrator will submit for a separate FCC ID. The submission should include end product
information, end product SAR/MPE test report and a reference to RIM module FCC ID
for all other Part 90 requirements.

Limits
1) SAR limits for General Population/Uncontrolled exposure is 1.6 W/kg for partial body
exposure, averaged over 1 g of tissue and 4 W/kg for hands, wrists and feet averaged over
10 g of tissue. The limits for Occupational/Controlled exposure are more relaxed, i.e., 8
W/kg for partial body and 20 W/kg for hands, wrists and feet. The 1.6 W/kg limit applies
for most of RIM OEM integrators.
2) The limit for MPE is 0.6 mW/cm

Guidelines
RF exposure distance is based on normal operating proximity to the user’s body. This
distance is measured from the feed point of the antenna to the closest body part. A test
need to be performed to determine the passing distance that meets the exposure limits.
