１) Must use a PIFA antenna such as the WC0D-60 with gains not exceeding those shown in the table 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.

Antennas:

5G

PIFA antenna & 2.57 dBi

2.4G

PIFA antenna & 1.72 dBi

Notice to OEM integrator

Must use the device only in host devices that meet the FCC RF exposure category of mobile, which means the device

is installed and used at distances of at least 20cm from persons.

The end user manual shall include FCC Part 15 /ISED RSS GEN compliance statements related to the transmitter as

show in this manual.

Host manufacturer is responsible for compliance of the host system with module installed with all other applicable

requirements for the system such as Part 15 B, ICES 003.

Host manufacturer is strongly recommended to confirm compliance with FCC requirements for the transmitter when

the module is installed in the host.

Must have on the host device a label showing Contains FCC ID: 2AC23-DCT2E

The use condition limitations extend to professional users, then instructions must state that this information also

extends to the host manufacturer’s instruction manual.

This module is stand-alone modular. If the end product will involve the Multiple simultaneously transmitting

condition or different operational conditions for a stand-alone modular transmitter in a host, host manufacturer

have to consult with module manufacturer for the installation method in end system.

Modular Approval Request FCC (Per 15.212) FCC ID: 2AC23-DCT2E Items to be covered Answer From Applicant 1. The modular transmitter must have its own RF shielding. Yes 2. The modular transmitter must have buffered modulation/data inputs (if Yes such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-

modulation. 3. The modular transmitter must have its own power supply regulation. Yes 4. The modular transmitter must comply with the antenna requirements of Yes Section 15.203 and 15.204(c). The antenna must either be permanently attached or employ a "unique" antenna coupler (at all connections between the module and the antenna, including the cable). 5. The modular transmitter must be tested in a stand-alone configuration, Yes i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. 6. The modular transmitter must be labeled with its own FCC ID number, Yes and, if the FCC ID 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 the following: "Contains Transmitter Module FCC ID: XYZMODEL1" or "Contains FCC ID: XYZMODEL1."

Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. 7. The modular transmitter must comply with any specific rule or Yes operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(ee), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. 8. The modular transmitter must comply with any applicable RF exposure Yes requirements. For example, FCC Rules in Sections 2.1091, 2.1093 and specific Sections of Part 15,including 15.319(i), 15.407(f), 15.253() and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance in accordance with Section 15.247(b) (4). Modular transmitters approved under other Sections of Part 15,when necessary, may also need to address certain RF Exposure concerns, typically by providing specific |

installation and operating instructions for users, installers and other interested parties to ensure compliance. Note: If compliance with one or more of the numbered requirements, listed above, cannot be demonstrated, it may be possible to obtain a Limited Modular Approval (LMA).
