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.
