FCC Certification Requirements.
According to the definition of mobile and fixed device is described in Part 2.1091(b), this device is a
mobile device.
And the following conditions must be met:
1. This Modular Approval is limited to OEM installation for mobile and fixed applications only. The antenna
installation and operating configurations of this transmitter, including any applicable source-based
timeaveraging duty factor, antenna gain and cable loss must satisfy MPE categorical Exclusion
Requirements of 2.1091.
2. The EUT is a mobile device; maintain at least a 20 cm separation between the EUT and the user’s
body and must not transmit simultaneously with any other antenna or transmitter.
3. A label with the following statements must be attached to the host end product: This device contains
FCC ID: XMR2021EC25AFDL
4. To comply with FCC regulations limiting both maximum RF output power and human exposure to RF
radiation, maximum antenna gain (including cable loss) must not exceed:
❒ LTE Band 2 :≤8.000dBi
❒ LTE Band 4:≤8.000dBi
❒ LTE Band 5 :≤6.00dBi
❒ LTE Band 12 :≤5.004dBi
❒ LTE Band 13:≤5.00dBi
❒ LTE Band 14:≤5.00dBi
❒ LTE Band 26:≤8.00dBi
❒ LTE Band 71:≤5.00dBi
5. This module must not transmit simultaneously with any other antenna or transmitter
6. The host end product must include a user manual that clearly defines operating requirements and
conditions that must be observed to ensure compliance with current FCC RF exposure guidelines.
For portable devices, in addition to the conditions 3 through 6 described above, a separate approval is
required to satisfy the SAR requirements of FCC Part 2.1093
If the device is used for other equipment that separate approval is required for all other operating
