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.
Simultaneous Transmission Evaluation
This module has not been evaluated or approved for simultaneous transmission as it is impossible to determine the
exact multi-transmission scenario that a host manufacturer may choose. Any simultaneous transmission condition
established through module integration into a host product must be evaluated per the requirements in
KDB447498D01(8) and KDB616217D01,D03 (for laptop, notebook, netbook, and tablet applications).
These requirements include, but are not limited to:
• Transmitters and modules certified for mobile or portable exposure conditions can be incorporated in mobile
host devices without further testing or certification when:
• The closest separation among all simultaneous transmitting antennas is >20 cm,
Or
• Antenna separation distance and MPE compliance requirements for ALL simultaneous transmitting antennas
have been specified in the application filing of at least one of the certified transmitters within the host device.
In addition, when transmitters certified for portable use are incorporated in a mobile host device, the antenna(s)
must be >5 cm from all other simultaneous transmitting antennas.
• All antennas in the final product must be at least 20 cm from users and nearby persons.
