which are connected with your applications.
This document can help you quickly understand module interface specifications, electrical and
mechanical details, as well as other related information of EG91 series module. With application note and
user guide, you can use EG91 series module to design and set up mobile applications easily.
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: XMR2021EG91NAXDL
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 :≤8.500dBi
❒ LTE Band 4:≤5.500dBi
❒ LTE Band 5 :≤9.908dBi
❒ LTE Band 12 :≤9.197 dBi
❒ LTE Band 13:≤9.656dBi
❒ LTE Band 25:≤8.000dBi
❒ LTE Band 26(Part 22):≤9.408dBi
LTE Band 26(Part 90):≤9.361dBi
❒
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 configurations,
including portable configurations with respect to 2.1093 and different antenna configurations.
