Device Classifications
Since host devices vary widely with design features and configurations module integrators shall
follow the guidelines below regarding device classification and simultaneous transmission, and
seek guidance from their preferred regulatory test lab to determine how regulatory guidelines will
impact the device compliance. Proactive management of the regulatory process will minimize
unexpected schedule delays and costs due to unplanned testing activities.
The module integrator must determine the minimum distance required between their host device
and the user’s body. The FCC provides device classification definitions to assist in making the
correct determination. Note that these classifications are guidelines only; strict adherence to a
device classification may not satisfy the regulatory requirement as near-body device design
details may vary widely. Your preferred test lab will be able to assist in determining the
appropriate device category for your host product and if a KDB or PBA must be submitted to the
FCC.
Note, the module you are using has been granted modular approval for mobile applications.
Portable applications may require further RF exposure (SAR) evaluations. It is also likely that the
host / module combination will need to undergo testing for FCC Part 15 regardless of the device
classification. Your preferred test lab will be able to assist in determining the exact tests which
are required on the host / module combination.
FCC Definitions
Portable: (§2.1093) — A portable device is defined as a transmitting device designed to be used
so that the radiating structure(s) of the device is / are within 20 centimeters of the body of the
user.
Mobile: (§2.1091) (b) — 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 centimeters is normally maintained between the transmitter’s radiating structure(s) and
the body of the user or nearby persons. Per §2.1091d(d)(4) In some cases (for example, modular
or desktop transmitters), the potential conditions of use of a device may not allow easy
classification of that device as either Mobile or Portable. In these cases, applicants are
responsible for determining minimum distances for compliance for the intended use and
installation of the device based on evaluation of either specific absorption rate (SAR), field
strength, or power density, whichever is most appropriate.
