1. Introduction
BL-M8852BP2 is a highly integrated Dual-band WLAN+Bluetooth Combo module. It combines a
2T2R Dual-band WLAN subsystem with PCI Express interface controllers and a Bluetooth v5.2
subsystem with UART interface controller. The module compatible IEEE 802.11a/b/g/n/ac/ax
standard and provides the maximum PHY rate up to 1201Mbps, it supports Bluetooth dual mode
with v5.2/v4.2/v2.1 compliant. The module provides a complete solution for high-performance
integrated WALN and Bluetooth devices such as OTT Boxes, Set-top Boxes, HD Cameras, etc.
1.1 Features

2.5
Trace antenna designs: applicable.
Any deviation(s) from the defined parameters of the antenna trace, as described by the instructions, require that the
host product manufacturer must notify the module grantee that they wish to change the antenna trace design. in this
case, a Class ll permissive change application is required to be filed by the grantee, or the host manufacturer can
take responsibility through the change in FCC lD (new application) procedure followed by a Class ll permissive
change application.
The device must be professionally installed.
The intended use is generally not for the general public.
It is generally for industry/commercial use.
The connector is within the transmitter enclosure and can only be accessed by disassembly of the transmitter that is
not normally required.
The user has no access to the connector.
Installation must be controlled.
Installation requires special training.
2.6
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This
equipment should be installed and operated with a minimum distance of 20cm between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
2.7
The following antennas have been certified for use with this module.
Only antennas of the same type with equal or lower gain may also be used with this module.
Other types of antennas and/or higher gain antennas may require the additional authorization for operation. The
installer should use unique antenna connector and 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. The
manufacturer of module will inform installer to meet with the FCC part 15.203 in the warning part.

2.8
Please notice that if the FCC identification number 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 "Contains FCC ID: 2AL6K-BLM8852BP2 "; any similar
wording that expresses the same meaning may be used.
2.9
Testing of the host product with all the transmitters installed - referred to as the composite investigation test- is
recommended, to verify that the host product meets all the applicable FCC rules. The radio spectrum is to be
investigated with all the transmitters in the final host product functioning to determine that no emissions exceed the
highest limit permitted for any one individual transmitter as required by Section 2.947(f). The host manufacturer is
responsible to ensure that when their product operates as intended it does not have any emissions present that are
out of compliance that were not present when the transmitters were tested individually.
If the modular transmitter has been fully tested by the module grantee on the required number of channels,
modulation types, and modes, it should not be necessary for the host installer to re-test all the available transmitter
modes or settings. lt is recommended that the host product manufacturer, installing the modular transmitter,
perform some investigative measurements to confirm that the resulting composite system does not exceed the
spurious emissions limits or band edge limits (e.g., where a different antenna may be causing additional emissions).
The testing should check for emissions that may occur due to the intermixing of emissions with the other
transmitters, digital circuitry, or due to physical properties of the host product (enclosure). This investigation is
especially important when integrating multiple modular transmitters where the certification is based on testing each
of them in a stand-alone configuration.
2.10
Any company of the host device which install this modular should perform the test of radiated & conducted
emission and spurious emission etc. according to FCC Part 15C: 15.247 and15.209 & 15.207, part 15E: 15.407,
part 15B: class B requirement, only if the test result comply with FCC part 15C: 15.247 and 15.209 & 15.207 part
15 E 15.407, 15B class B requirement. Then the host can be sold legally.
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, lf the grantee markets their product as being Part 15
Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a
notice stating that the final host product still
requires Part 15 Subpart B compliance testing with the modular transmitter installed.
