Warning statement
FCC STATEMENT
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.
2. 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.
FCC Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance
20cm between the radiator & your body.
The EMW3162 module is designed to comply with the FCC statement. FCC ID is
P53-EMW3162. The host system using EMW3162, should have label indicated FCC ID
P53-EMW3162.

1. Introduction
Project Name: Embedded M2M Module with Broadcom 802.11bgn (1x1) WiFi.
Project Number: T77H497.00.
This documentation describes the engineering requirements specification of WiFi module
with T77H497.00. It is a confidential document of Foxconn.
1.1 RF module Overview
This M2M (Machine to Machine) module integrates 32 bit MCU and Broadcom WiFi. It
provides wireless modem functionality utilizing direct sequence spread spectrum and
OFDM/CCK technology. It operates in 2.4GHz ISM band, compatible with the IEEE
802.11b/g/n standard. It can implement the wireless network function on the embedded
devices easily and improve the product’s competitiveness. It supports TCP/IP protocol and
all of the Wi-Fi security. This module has implemented some efficient mechanisms in its
software and hardware to maximize the performance.
The functional block diagram is shown in Figure .1.
