10.5 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.

10.6 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.

10.7 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).

As mentioned above, the DWM3001C has been granted modular approval as a “Portable” device. However, end-customer Portable

applications may require further RF exposure (SAR) evaluations. It is also possible that the host / module combination will need to

undergo further testing for FCC Part 15 compliance 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.

10.8 Operating Requirements and Conditions

The design of DWM3001 complies with U.S. Federal Communications Commission (FCC) guidelines respecting safety levels of radio

frequency (RF) exposure for Portable devices.

10.9 Miscellaneous

Except as otherwise described above, the DWM3001C BLE and UWB transmitters meets all requirements for SAR or RF Exposure,

intended or unintended, under FCC, ISED, and ETSI rules. The BLE radio falls well below the limit determined for <5mm separation (a

“body-worn” device) and, for a UWB radio operating above 6GHz, there are currently no exposure limits specified.

All products developed by the user incorporating the DWM3001C must be approved by the relevant authority governing radio emissions

in any given jurisdiction prior to the marketing or sale of such products in that jurisdiction and user bears all responsibility for obtaining

such approval as needed from the appropriate authorities.
