1. Introduction
Project Name: 11n USB WiFi Module with RT5372L
Project Number: T77H387.00
This documentation describes the engineering requirements specification of WiFi module
with RT5372. It is a confidential document of CyberTan.
1.1 RF module Overview
The general HW architecture for the module is shown in Figure 1. This WLAN Module
design is based on Ralink RT5372L. It is a highly integrated single-chip MIMO (Multiple In
Multiple Out) Wireless LAN (WLAN) USB2.0 network interface controller complying with
the 802.11n specification. It combines a MAC, a 2T2R capable baseband, and RF in a
single chip. The RT5372 provides a complete solution for a high throughput performance
wireless client.

Appendix D-Federal Communication Commission Interference
Statement
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 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 Caution:
Any changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate this equipment. 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.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This transmitter module must not be co-located or operating in conjunction with any
other antenna or transmitter. This End equipment should be installed and operated with a minimum
distance of 20 centimeters between the radiator and your body.
IMPORTANT NOTE:
In the event that these conditions can not be met (for example certain laptop configurations or
co-location with another transmitter), then the FCC authorization is no longer considered valid and
the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be
responsible for re-evaluating the end product (including the transmitter) and obtaining a separate
FCC authorization.
End Product Labeling
The final end product must be labeled in a visible area with the following: “Contains FCC ID:
N89-WU172HS”.
Manual Information to the End User
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.
