The Module is designed to comply with the FCC statement. FCC ID is 2BMXW-S2022EU3. The host system using
Module, should have label indicated it contain modular’s FCC ID: 2BMXW-S2022EU3. This radio module must not
installed to collocate and operating simultaneously with other radios in host system additional testing and equipment
authorization may be required to operating simultaneously with other radio.
The Module and its antenna must not be co-located or operating in conjunction with any other transmitter or antenna
within a host device.
The modular must be installed in the host that assign by Company name: Sonix Technology Co., Ltd., Model no.:
S2022EU3 if other host types used would need further evaluation and possible C2PC if they are not significantly
similar to the one tested The WIFI Module is designed for a compact PCB design. It should be installed and operated
with host or other minimum distance of 20 centimeters between the radiator and your body." To comply with FCC
regulations limiting both maximum RF output power and human exposure to RF radiation, the maximum antenna gain
including cable loss in a mobile-only exposure condition must not exceed 0.5 dBi in the 5G. The module uses External
antenna, the antennas are sold with the module.
Notice to OEM integrator
The end user manual shall include all required regulatory information/warning as show in this manual. The OEM
integrator is responsible for testing their end-product for any additional compliance requirements required with this
module installed. If the final product contains circuits of other FCC PART 15 Subparts, the final host product still
requires Part 15 Subpart B compliance testing with the modular transmitter installed The intended use is generally not
for the general public. It is generally for industry/commercial use. The connector is within the transmitter enclosure and
can only be accessed by disassembly of the transmitter that is not normally required, the user has no access to the
connector. Installation must be controlled. Installation requires special training.
This device complies with Part 15 of the FCC Rules.
This equipment should be installed and operated with a minimum distance of 20 cm between the radiator and your
body.
2.2
This module has been assessed against the following FCC rule parts: CFR 47 FCC Part 15 E (NlI). lt is applicable to
the modular transmitter.
2.3
This radio transmitter Module has been approved by Federal Communications Commission to operate with the
antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list that
have a gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device.
The concrete contents to check are the following three points.
1) Maximum antenna gains are shown in item 2.7 below.
2) Should be installed so that the end user cannot modify the antenna
3) Feed line should be designed in 50ohm
Fine-tuning of return loss etc. can be performed using a matching network.
The antenna shall not be accessible for modification or change by the end user.
2.4
The module complies with FCC Part 15.407 and apply for Single module approval.
2.5
Trace antenna designs: applicable.
Any deviation(s) from the defined parameters of the antenna trace, as described by the instructions, require that
the host product manufacturer must notify the module grantee that they wish to change the antenna trace
design. in this case, a Class ll permissive change application is required to be filed by the grantee, or the host
manufacturer can take responsibility through the change in FCC lD (new application) procedure followed by a
Class ll permissive change application.
The device must be professionally installed.
The intended use is generally not for the general public.
It is generally for industry/commercial use.
The connector is within the transmitter enclosure and can only be accessed by disassembly of the transmitter
that is not normally required.
The user has no access to the connector.
Installation must be controlled.
Installation requires special training.
2.6
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This
equipment should be installed and operated with a minimum distance of 20cm between the radiator & your
body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
2.7
The following antennas have been certified for use with this module.
Only antennas of the same type with equal or lower gain may also be used with this module.
Other types of antennas and/or higher gain antennas may require the additional authorization for operation. The
installer should use unique antenna connector and Antenna types not included in this list that have a gain
greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device. The
manufacturer of module will inform installer to meet with the FCC part 15.203 in the warning part.
Antenna Specification list below:
5G:
Antenna type: External antenna
The max antenna gain (in dBi):
Antenna 1: 0.5dBi
Antenna 2: 0.5dBi
2.8Please notice that if the FCC identification number is not visible when the module is installed
inside another device, then the outside of the device into which the module is installed must also
display a label referring to the enclosed module. This exterior label can use wording such as "
Contains FCC ID: 2BMXW-S2022EU3 "; any similar wording that expresses the same meaning may
be used.
2.9
Testing of the host product with all the transmitters installed - referred to as the composite investigation test- is
recommended, to verify that the host product meets all the applicable FCC rules. The radio spectrum is to be
investigated with all the transmitters in the final host product functioning to determine that no emissions exceed
the highest limit permitted for any one individual transmitter as required by Section 2.947(f). The host
manufacturer is responsible to ensure that when their product operates as intended it does not have any
emissions present that are out of compliance that were not present when the transmitters were tested
individually.
If the modular transmitter has been fully tested by the module grantee on the required number of channels,
modulation types, and modes, it should not be necessary for the host installer to re-test all the available
transmitter modes or settings. lt is recommended that the host product manufacturer, installing the modular
transmitter, perform some investigative measurements to confirm that the resulting composite system does not
exceed the spurious emissions limits or band edge limits (e.g., where a different antenna may be causing
additional emissions).The testing should check for emissions that may occur due to the intermixing of
emissions with the other transmitters, digital circuitry, or due to physical properties of the host
product (enclosure). This investigation is especially important when integrating multiple modular
transmitters where the certification is based on testing each of them in a stand-alone
configuration.
2.10
Any company of the host device which install this modular should perform the test of radiated & conducted emission
and spurious emission etc. according to 15.209 & 15.207, part 15E: 15.407, part 15B: class B requirement, only if
the test result comply with 15.209 & 15.207 part 15 E 15.407, 15B class B requirement. Then the host can be sold
legally.
The host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not
covered by the modular transmitter grant of certification, lf the grantee markets their product as being Part 15
Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a
notice stating that the final host product still
requires Part 15 Subpart B compliance testing with the modular transmitter installed.
