                                             Device Types
                      A fixed device is defined as a device physically secured at one fixed location
Fixed
                      and cannot be easily re-located.
                      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
Mobile                distance of at least 20 centimeters is normally maintained between the
                      transmitter's radiating structure(s) and the body of the user or nearby persons.
                      (47 CFR 2.1091)
                      A portable device is defined as a transmitting device designed to be used so
Portable              that the radiating structure(s) of the device is/are within 20 centimeters of the
                      body of the user. (47 CFR 2.1093)
                                        Exposure Categories
                     Limits apply in situations in which persons are exposed as a consequence of
                     their employment provided those persons are fully aware of the potential for
Occupational /       exposure and can exercise control over their exposure. Limits for
Controlled           occupational/controlled exposure also apply in situations when an individual is
                     transient through a location where occupational/controlled limits apply provided
                     he or she is made aware of the potential for exposure.
                     Exposures apply in situations in which the general public may be exposed, or in
General population / which persons that are exposed as a consequence of their employment may
uncontrolled         not be fully aware of the potential for exposure or cannot exercise control over
                     their exposure.

                                         Assessment procedure
Standalone operation assessment:

For each radio and frequency band the worst case transmission mode with the highest peak
conducted or radiated power is evaluated at the frequency that results in the most restrictive rf-
exposure limit. From the peak power values, antenna gains and duty cycles taken from the reference
documents, the source average radiated power values are calculated. From the average radiated
power the power densities at antenna far-field distance, at 20cm separation distance from the
radiation source is calculated. Compliance with the RF-Exposure limit is determined at 20cm
separation distance.

Concurrent operation assessment:

First the evaluation distance is set to 20 cm. The ratios of the power densities and/or field strength
values and the corresponding limits are calculated and summed and the sum is compared to the
maximum of 1.
