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.
IMPORTANT NOTE:
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.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
ii
Preface
This device is intended only for OEM integrators under the following conditions:
1)
The antenna must be installed such that 20 cm is maintained between the 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 be required. However, the OEM integrator is still responsible
for testing their end-product for any additional compliance requirements required with this module installed (for example,
digital device emissions, PC peripheral requirements, etc.).
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
This transmitter module is authorized only for use in device where
the antenna may be installed such that 20 cm may be maintained
between the antenna and users (for example access points, routers,
wireless ADSL modems, and similar equipment). The final end
product must be labeled in a visible area with the following: “Contains TX FCC ID: O6M-WM253”.
iii
WLAN Mini module quick guide
Manual Information That Must be Included

What is Wireless LAN?
Wireless Local Area Network (WLAN) systems offer a great number of advantages over traditional wired systems. WLANs are
flexible and easy to setup and manage. They are also more economical than wired LAN systems.
Using radio frequency (RF) technology, WLANs transmit and receive data through the air. WLANs combine data connectivity
with user mobility. For example, users can roam from a conference room to their office without being disconnected from the
LAN.
Using WLANs, users can conveniently access shared information,
and network administrators can configure and augment networks
without installing or moving network cables.
WLAN technology provides users with many convenient and cost
saving features:
•
Mobility: WLANs provide LAN users with access to realtime information anywhere in their organization, providing
service opportunities that are impossible with wired networks.
•
Ease of Installation: Installing is easy for novice and expert users alike, eliminating the need to install network
cables in walls and ceilings.
•
Scalability: WLANs can be configured in a variety of topologies to adapt to specific applications and installations.
Configurations are easily changed and range from peer-topeer networks suitable for a small number of users to full
infrastructure networks of thousands of users roaming over
a broad area.
—Introduction
LAN Modes
Wireless LANs can be configured in one of two ways:
Ad-hoc
Networking
Also known as a peer-to-peer network, an ad-hoc network is one that allows all workstations and computers
in the network to act as servers to all other users on
the network. Users on the network can share files,
print to a shared printer, and access the Internet with a
shared modem. However, with ad-hoc networking,
users can only communicate with other wireless LAN
computers that are in the wireless LAN workgroup, and
are within range.
Infrastructure
Networking
Infrastructure networking differs from ad-hoc networking in that it includes an access point. Unlike the adhoc structure where users on the LAN contend the
shared bandwidth, on 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.
Infrastructure networking has the following advantages
over ad-hoc networking:
•
Extended range: each wireless LAN computer
within the range of the access point can communicate with other wireless LAN computers within
range of the access point.
•
Roaming: the access point enables a wireless
LAN computer to move through a building and
still be connected to the LAN.
•
Wired to wireless LAN connectivity: the access
point bridges the gap between wireless LANs and
their wired counterparts.

Notes on wireless LAN configuration
When configuring a wireless LAN (WLAN), be sure to note the
following points:
•
Optimize the performance of the WLAN by ensuring that
the distance between access points is not too far. In most
buildings, WLAN cards operate within a range of 100 ~
300 feet, depending on the thickness and structure of the
walls.
•
Radio waves can pass through walls and glass but not
metal. If there is interference in transmitting through a wall,
it may be that the wall has reinforcing metal in its structure.
Install another access point to circumvent this problem.
•
Floors usually have metal girders and metal reinforcing
struts that interfere with WLAN transmission.
