1. Introduction
CRI I9074L is a high perform M.2 module to leverage QCN9074 chip with Qualcomm®
802.11ax technology which is a highly integrated wireless local area network (WLAN)
system-on chip (SoC) for 2.4/5/6 GHz IEEE802.11ax/ac/n/g/b/a applications. QCN9074
performs AP and STA functionality with 4x4 MIMO and 4 spatial streams. The
QCN9074 is a dual-synthesizer WLAN radio with native 160 MHz support, and through
PCIe to access for Enterprise Access Points and Campus deployments.
The QCN9074 chip platform is a single band 4x4 802.11 ax WLAN. The I9074L M.2
module is includes 2.4 GHz and 5 GHz, however it only works in either 2.4 GHz or 5
GHz, not dual band operation.

7. RF Certification Notice
NOTICE
The OEM integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the user’s manual of the end
product which integrates this module. The end user manual shall include all required
regulatory information/warning as shown in User manual.
Unlicensed radiator / License-exempt radiator
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1) this device may not cause harmful interference and
2) this device must accept any interference received, including interference that may
cause undesired operation.
You are cautioned that changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
List of applicable FCC rules
This module has been tested and found to comply with the following requirements for
Modular Approval.
47 CFR Part 15 Subpart C Intentional Radiators
47 CFR Part 15 Subpart E Unlicensed National Information Infrastructure Devices
47 CFR Part 15 Subpart F Ultra-Wideband Operation
Limited module procedures
by case…
RF exposure considerations
1. The host product operating conditions must be such that there is a minimum
separation distance of 20 cm (or possibly greater than 20 cm) between the antenna
radiating structures and nearby persons. The host manufacturer is obligated to
confirm the use conditions of the host product to ensure that the distance specified
in the instructions is met. In this case the host product is classified as either a
mobile device or a fixed device for RF exposure purposes.
2. If the modular transmitter to be used in a specific type of host platform and installed
such that it can be operated at closer than 20 cm to users or nearby persons,
please follow below guidance.
a. For the host product integrated with this modular transmitter as a stand-alone
configuration, the maximum conducted power from the original grant shall be
retained in order to meet SAR exemption requirements.
b. For configuration with multiple transmitters in the same host, routine evaluation
or SAR testing for the simultaneous transmission of the co-located transmitters
I9074L M.2 MODULE USER MANUAL
I9074L 8 COREXOM
according to KDB 447498 is required. The potable host product shall be
evaluated for ensuring to continue compliance FCC rule part 2.1093 & part
1.1310 by C2PC. The additional guidance for the portable host products is
provided in KDB Publication 996369 D02 and D04.
c. For the host product is not installed according to this guide, the module
certification will be invalid, and a new grant certification will be required for the
host product.
ANTENNAS
This radio transmitter has been approved by Federal Communications Commission
and Innovation, Science and Economic Development Canada 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.
Label and compliance information
The host device integrating this module must be labeled with the following regulatory
identifiers to ensure compliance with regulations, these labels must be clearly visible
on the exterior of the host device's enclosure as required by applicable regulatory
guidelines.
Contains FCC ID: 2BPQQ-I9074L
Information on test modes and additional testing requirements
The module can be configured to continuously transmit on a specific frequency with a
fixed modulation pattern. This allows evaluation of radiated emissions and spurious
emissions in a controlled condition.
These test modes are intended for compliance testing only and must not be enabled
during normal operation of the final product.
For more detailed information, please contact the grantee for assistance with test
modes needed for module/host compliance test requirements.
Additional testing, Part 15 Subpart B disclaimer
The modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC
transmitter rules) listed on the grant, and that 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.
The final host product still requires Part 15 Subpart B compliance testing with the
modular transmitter installed.

I9074L 9 COREXOM
Note EMI Considerations
Note that a host manufacture is recommended to use KDB996369 D04 Module
Integration Guide recommending as "best practice" RF design engineering testing and
evaluation in case non-linear interactions generate additional non-compliant limits due
to module placement to host components or properties.
For standalone mode, reference the guidance in KDB996369 D04 Module Integration
Guide and for simultaneous mode; see KDB996369 D02 Module Q&A Question 12,
which permits the host manufacturer to confirm compliance.
How to make changes
Only Grantees are permitted to make permissive changes, if the module will be used
differently than granted conditions, please contact us to ensure modifications will not
affect compliance.
