4. Introduction

BL-R8822BU1 module design is based on Realtek RTL8822BU solution, The RTL8822BU is a
highly integrated single chip which has built in a 2x2 dual-band wireless LAN radio and Bluetooth
radio.It includes Bluetooth EDR and LE radio which complies with Bluetooth v2.1+EDR, v3.0,
v4.0+BLE andV4.2.The Module is a highly integrated MAC/BBP and 2.4/5GHz PA/LNA single
chip which supports a 866.7Mbps PHY rate. The Module is designed to support standard-based
features in the areas of security, quality of service, and international regulations, giving end
users the greatest performance anytime and in any circumstance. This documentation describes
the engineering requirements specification.

6 Antenna

WIFI:Connect to external antenna through the connector,The gain of the external antenna is

2dBi, the length of the antenna is 200mm, the internal structure is copper tube structure.

Antenna manufacturer： Shenzhen Bilian Electronic Co.，Ltd.
External antenna model: Black knife antenna
Antenna gain:2dBi

WIFI Antenna

BT Antenna

BT:

The module needs to be attached to the PCB board and connected to the external antenna through the PIN 30

solder joint of the circuit on the PCB. The gain of the external antenna is 2dBi, the length of the antenna is

200mm, the internal structure is copper tube structure. A resistance of 0R is added between the module and the

antenna at R8 to ensure that the impedance of the connection between the module and the antenna reaches

50R.J1 position on PCB is the position of external antenna.

FCC Statement
FCC standards: FCC CFR Title 47 Part 15 Subpart C Section 15.247 ,15.407

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.

Any Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.

Note: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation.

This equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur

in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following

measures:

—Reorient or relocate the receiving antenna.

—Increase the separation between the equipment and receiver.

—Connect the equipment into an outlet on a circuit different from that to which the receiver is

connected.

—Consult the dealer or an experienced radio/TV technician for help.

We will retain control over the final installation of the modular such that compliance of the end
product is assured. In such cases, an operating condition on the limit modular approval for the
module must be only approved for use when installed in devices

produced by a specific manufacturer. If any hardware modify or RF control software modify
will be made by host manufacturer,C2PC or new certificate should be apply to get approval,if
those change and modification made by host manufacturer not

expressly approved by the party responsible for compliance ,then it is illegal.

FCC Radiation Exposure Statement

The modular can be installed or integrated in mobile or fix devices only. This modular cannot
be installed in any portable device.This modular complies with FCC RF radiation exposure limits
set forth for an uncontrolled environment. This transmitter must

not be co-located or operating in conjunction with any other antenna or transmitter. This
modular must be installed and operated with a minimum distance of 20 cm between the radiator
and user body.

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 the following: “Contains Transmitter Module FCC ID: 2AL6K-R8822BU1-A Or

7

Contains FCC ID: 2AL6K-R8822BU1-A”

When the module is installed inside another device, the user manual of the host must contain
below warning

statements;

1. 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.

(2) This device must accept any interference received, including interference that may cause
undesired operation.

Note: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation.

This equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications.

However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged

to try to correct the interference by one or more of the following measures:

—Reorient or relocate the receiving antenna.

—Increase the separation between the equipment and receiver.

—Connect the equipment into an outlet on a circuit different from that to which the receiver is

connected.

—Consult the dealer or an experienced radio/TV technician for help.

2. Changes or modifications not expressly approved by the party responsible for compliance

could void the user's authority to operate the equipment.

The devices must be installed and used in strict accordance with the manufacturer's
instructions as described in the user documentation that comes with the product.

Any company of the host device which install this modular with modular approval should
perform the test of radiated & conducted emission and spurious emission,etc. according to FCC
part 15C : 15.247 and 15.407 and 15.209 & 15.207 ,15B Class B

requirement, Only if the test result comply with FCC part 15C : 15.247 and 15.407 and 15.209
& 15.207 ,15B Class B requirement，then the host can be sold legally.
