user than a unique (non-standard) antenna connector (as permissible by FCC) must be used (e.g. RP
(Reverse Polarity)-SMA socket). If an RF coaxial cable is used between the module RF output and the enclosure, than a unique (non-
standard) antenna connector must be used in the enclosure wall for interface with antenna. 1 2 3 4 5 6 7 8 Note:
1 Preliminary Revision 0.0 (06/2020) Regulatory Compliance Information 1.2 WFI32E01 Usage Instructions under Modular Approval Table 1-2: Features and supported modes of operation Frequency Range Wi-Fi: 2.400 GHz ~ 2.4835 GHz (2.4 GHz ISM Band) Number of Channels Wi-Fi: 11 for North America The availability of some specific channels and/or operational frequency bands are country dependent and should be programmed at the Host product factory to match the intended destination. Regulatory bodies prohibit exposing the settings to the end user. This requirement needs to be taken care of via Host implementation. The Host product manufacturer must ensure that the RF behavior adheres to the certification (e.g. FCC, ISED) requirements when the module is installed in the final Host product. 1.3 WFI32E01 Usage Instructions under Modular Approval Host Board Top Layer Instructions:
The top layer (underneath the module) of the host PCB must be ground with as many GND vias as possible. 2 Preliminary Revision 0.0 (06/2020) Regulatory Compliance Information 2.1 United States The WFI32E01 modules have received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C Intentional Radiators single-modular approval in accordance with Part 15.212 Modular Transmitter approval. Single modular transmitter approval is defined as a complete RF transmission sub-assembly, designed to be incorporated into another device, that must demonstrate compliance with FCC rules and policies independent of any host. A transmitter with a modular grant can be installed in different end-use products (referred to as a host, host product, or host device) by the grantee or other equipment manufacturer, then the host product may not require additional testing or equipment authorization for the transmitter function provided by that specific module or limited module device. The user must comply with all of the instructions provided by the Grantee, which indicate installation and/or operating conditions necessary for compliance. A host product itself is required to comply with all other applicable FCC equipment authorization regulations, requirements, and equipment functions that are not associated with the transmitter module portion. For example, compliance must be demonstrated: to regulations for other transmitter components within a host product; to requirements for unintentional radiators (Part 15 Subpart B), such as digital devices, computer peripherals, radio receivers, etc.; and to additional authorization requirements for the non-transmitter functions on the transmitter module (i.e., SDoC or Certification) as appropriate (e.g., Bluetooth and Wi-Fi transmitter modules may also contain digital logic functions). 2.1.1 Labeling and User Information Requirements The WFI32E01 module has been labeled with its own FCC ID number. If the FCC ID is not visible when the module is installed inside another device, then the outside of the finished product into which the module is installed must display a label referring to the enclosed module. This exterior label can use wording as follows:
For the WFI32E01PE, WFI32E01UE, WFI32E01PC, WFI32E01UC:
Contains Transmitter Module FCC ID: 2ADHKWFI32E01 or Contains FCC ID: 2ADHKWFI32E01 This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. A user's manual for the finished product should include the following statement:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna Connect the equipment into an outlet on a circuit different from that to which the receiver is connected Increase the separation between the equipment and receiver 3 Preliminary Revision 0.0 (06/2020) Regulatory Compliance Information Consult the dealer or an experienced radio/TV technician for help Additional information on labeling and user information requirements for Part 15 devices can be found in KDB Publication 784748, which is available at the FCC Office of Engineering and Technology (OET) Laboratory Division Knowledge Database (KDB) https://apps.fcc.gov/oetcf/kdb/index.cfm 2.1.2 RF Exposure All transmitters regulated by FCC must comply with RF exposure requirements. KDB 447498 General RF Exposure Guidance provides guidance in determining whether proposed or existing transmitting facilities, operations or devices comply with limits for human exposure to Radio Frequency (RF) fields adopted by the Federal Communications Commission (FCC). From the FCC Grant: Output power listed is conducted. This transmitter is restricted for use with the specific antenna(s) tested in this application for Certification. In the end product, the antenna(s) used with this transmitter must be installed to provide a separation distance of at least 8.0 cm from all persons and must not be co-located or operation in conjunction with any other antenna or transmitter. User and installers must be provided with antenna installation instructions and transmitter operating conditions for satisfying the RF exposure compliance. 2.1.3 Approved Antenna Types To maintain modular approval in the United States, only the antenna types that have been tested shall be used. It is permissible to use a different antenna, provided the same antenna type and antenna gain
(equal to or less than) is used. An antenna type comprises antennas having similar in-band and out-of band radiation patterns. Antennas approved for WFI32E01 module with the antenna types are listed in Table 1-1. 2.1.4 Helpful Websites Federal Communications Commission (FCC): http://www.fcc.gov FCC Office of Engineering and Technology (OET) Laboratory Division Knowledge Database (KDB):
