FCC Caution

1. The 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.

2. FCC RF Radiation Exposure Statement: The equipment complies with FCC
RF radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with a minimum
distance of 20 centimeters between the radiator and your body.

3. This Transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter.

4. Changes or modifications to this unit not expressly approved by the
party responsible for compliance could void the user authority to operate
the equipment.

FCC Statement

This device is intended only for OEM integrators under the following

1) The antenna must be installed such that 20 cm is maintained between antenna

and users, and

2) The transmitter module may not be co-located with any other transmitter or

antenna.

As long as 2 conditions above are met, further transmitter test will not required. However,
the OEM integrator is still responsible for testing end-product for any additional compli­ance requirements required with module installed (for example, digital device emissions,
PC peripheral requirements, etc.).

Important Note

In the event that these conditions can not be example certain laptop configurations or co­location with another transmitter), then the FCC authorization is no longer considered
valid the FCC ID can not be used on the final product. In these circumstances, OEM
integrator will be responsible for re-evaluating the end product (including the transmitter)
and obtaining a separate FCC authorization.

Introduction

>>> 1.1 CM11BGN-BT (MS-3870) - Wireless 11b/g/n +

Bluetooth BT2.1 Combo Slim Module

MSI CM11BGN-BT (MS-3870), the Wireless 11b/g/n +
Bluetooth Combo Slim Module, which can be used to integrate
with such systems as notebook, mini-barebone, portable PC.
With MSI MS-3870 embedded inside, a system could provide
users with the ability and flexibility to connect up to Internet
wirelessly via 802.11b/g/n with speed up to 150Mbps, and to
link with peripherals wirelessly through BluetoothTM v2.1 and
advanced EDR (Enhanced Data Rate) technology. Bluetooth
v2.1 technology increases the data rate of BluetoothTM v1.1/1.2
from 1.0Mbps to 2.1Mbps.

MSI MS-3870 is taking advantage of leading technologies from
Ralink and CSR. It addresses the co-existence issues in PAN
(Personal Area Network) and WLAN (Wireless Local Area
Network) markets by providing true simultaneous connectivity
while deploying IEEE 802.11b/g/n and Bluetooth v2.1 Along
with this combo solution, a system installed with a single mod­ule is able to offer dual mode capability of WiFi and BluetoothTM.
It will benefit system vendors in miniaturization of system di­mension and BOM cost reduction, as well as also make users
happy with the all-in-one functionality.

>>> 1.2 How MS-3870 Works

In WLAN Environment1.2.1
Ad-hoc Mode : An Ad-hoc network is a local area network or

other small network, especially one with wireless or temporary
plug-in connections, in which some of the network devices are
part of the network only for the duration of a communications
session. Users in the network can share files, print to a shared
printer, and access the Internet with a shared modem. In this
kind of network, new devices can be quickly added; however,
users can only communicate with other wireless LAN comput­ers that are in this wireless LAN workgroup, and are within
range.

Infrastructure Mode : The difference between Infrastructure
network and Ad-hoc network is that the former one includes an
Access Point. In an Infrastructure network, the Access Point can
manage the bandwidth to maximize bandwidth utilization. Addi­tionally, the Access Point enables users on a wireless LAN to
access an existing wired network, allowing wireless users to take
advantage of the wired networks resources, such as Internet,
email, file transfer, and printer sharing. The scale and range of the
Infrastructure networking are larger and wider than that of the
Ad-hoc networking.

In Bluetooth Connection

1.2.2

The term “Bluetooth” refers to a worldwide standard for the
wireless exchange of data between two devices. In order to ex­change data, two Bluetooth devices must establish a connection.
Before a connection is established, one device must request a
connection with another. The second device accepts (or rejects)
the connection. The originator of the request is known as the
client. The device that accepts (or rejects) the request is known
as the server. Many Bluetooth devices can act as both client and
server. Every Bluetooth device that provides a service must be
prepared to respond to a connection request. Bluetooth soft­ware is always running in the background on the server, ready to
respond to connection requests.

determined by turning the equipment off and on, the user is encouraged to try to correct the interference by
one 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.

Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this
device must accept any interference, including interference that may cause undesired operation of the device.

IC Radiation Exposure Statement:
