Introduction

This document defines EC21 series Mini PCIe module, and describes its air interfaces and hardware

interfaces which are connected with customers’ applications.

This document helps customers quickly understand module interface specifications, electrical

characteristics, mechanical specifications and other related information of the module. To facilitate

application designs, it also includes some reference designs for customers’ reference. The document,

coupled with application notes and user guides, makes it easy to design and set up wireless applications

with EC21 series Mini PCIe.

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: XMR2021EC21ADL

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 :≤9.500dBi

❒

LTE Band 4:≤6.500dBi

❒

LTE Band 12 :≤

10.197

dBi

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.

For this device, OEM integrators must be provided with labeling instructions of finished products.

Please refer to KDB784748 D01 v07, section 8. Page 6/7 last two paragraphs:

A certified modular has the option to use a permanently affixed label, or an electronic label. For a permanently

affixed label, the module must be labeled with an FCC ID - Section 2.926 (see 2.2 Certification (labeling
