Federal Communication Commission Interference StatementThis equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a resi-dential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed andused in accordance with the instructions, may cause harmful interference to radio communications. However, thereis no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful in-terference to radio or television reception, which can be determined by turning the equipment off and on, the user isencouraged 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 thatto which the receiver is connected.- Consult the dealer or an experienced radio/TV technician for help.FCC Caution: To assure continued compliance, (example - use only shielded interface cables when connecting tocomputer or peripheral devices). Any changes or modifications not expressly approved by the party responsible forcompliance 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) Thisdevice may not cause harmful interference, and (2) this device must accept any interference received, including in-terference 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.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, and2) 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 in-tegrator is still responsible for testing their end-product for any additional compliance requirementsrequired 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 con-figurations or co-location with another transmitter), then the FCC authorization is no longer consideredvalid and the FCC ID can not be used on the final product. In these circumstances, the OEM integratorwill be responsible for re-evaluating the end product (including the transmitter) and obtaining a separateFCC authorization.End Product LabelingThis transmitter module is authorized only for use in device where the antenna may be installed such that20 cm may be maintained between the antenna and users (for example access points, routers, wirelessADSL modems, and similar equipment). The final end product must be labeled in a visible area with thefollowing: “Contains TX FCC ID: O6M-WM600I ”.Manual Information That Must be IncludedThe OEM integrator has to be aware not to provide information to the end user regarding how to install orremove this RF module in the users manual of the end product which integrate this module.The users manual for end users must include the following information in a prominent location“ IMPORTANT NOTE: To comply with FCC RF exposure compliance requirements, the antenna used forthis transmitter must be installed to provide a separation distance of at least 20 cm from all persons andmust not be co-located or operating in conjunction with any other antenna or transmitter.

1Chapter 1IntroductionThank you for using the Wireless Module. This high-speed 54Mbps Wireless Module provides you with an inno-vative wireless networking solution for your embedded system. The module is easy to set up and use. With thisinnovative wireless technology, you can share files and printers on the network—without inconvenient wires! Nowyou can carry the LAN in your pocket!This module is designed for1. Wireless LAN Printer Server2. Wireless LAN Ethernet Adapter3. Wireless LAN Access Point4. Wireless LAN Router / Gateway / Cable Modem5. Wireless LAN Broadband Router6. Wireless LAN Presentation GatewayFeatures• Wire-free access to networked resources from anywhere beyond the desktop• Low interference & high susceptibility guarantee reliable performance• Delivers data rate up to 54 Mbps• Dynamically shifts between 11G (draft) & 11B network speed, based on signal strength, for maximum availabilityand reliability of connection• Uses 2.4GHz frequency band, which complies with worldwide requirement• Used on embedded operating systems• Ensures great security by providing the Wired Equivalent Privacy (WEP) defined in the IEEE 802.11 standardWhat is Wireless LAN?Wireless Local Area Network (WLAN) systems offer a great number of advantages over traditional wired sys-tems. WLANs are flexible and easy to setup and manage. They are also more economical than wired LANsystems.Using radio frequency (RF) technology, WLANs transmit and receive data through the air. WLANs combinedata connectivity with user mobility. For example, users can roam from a conference room to their officewithout being disconnected from the LAN.Using WLANs, users can conveniently access shared information, and network administrators can configureand 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 real-time information anywhere in their organiza-tion, 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 installnetwork cables in walls and ceilings.• Scalability: WLANs can be configured in a variety of topologies to adapt to specific applications andinstallations. Configurations are easily changed and range from peer-to-peer networks suitable for asmall number of users to full infrastructure networks of thousands of users roaming over a broad area.
54M Wireless LAN Module2LAN ModesWireless LANs can be configured in one of two ways:Ad-hocNetworkingAlso known as a peer-to-peer network, an ad-hoc net-work is one that allows all workstations and computersin the network to act as servers to all other users on thenetwork. Users on the network can share files, print toa shared printer, and access the Internet with a sharedmodem. However, with ad-hoc networking, users canonly communicate with other wireless LAN computersthat are in the wireless LAN workgroup, and are withinrange.InfrastructureNetworkingInfrastructure networking differs from ad-hoc network-ing in that it includes an access point. Unlike the ad-hoc structure where users on the LAN contend theshared bandwidth, on an infrastructure network theaccess point can manage the bandwidth to maximizebandwidth utilization.Additionally, the access point enables users on a wire-less LAN to access an existing wired network, allowingwireless users to take advantage of the wired networksresources, such as Internet, email, file transfer, andprinter sharing.Infrastructure networking has the following advantagesover ad-hoc networking:• Extended range: each wireless LAN computerwithin the range of the access point can commu-nicate with other wireless LAN computers withinrange of the access point.• Roaming: the access point enables a wirelessLAN computer to move through a building and stillbe connected to the LAN.• Wired to wireless LAN connectivity: the accesspoint bridges the gap between wireless LANs andtheir wired counterparts.Notes on wireless LAN configurationWhen 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 toofar. In most buildings, WLAN cards operate within a range of 100 ~ 300 feet, depending on the thick-ness and structure of the walls.• Radio waves can pass through walls and glass but not metal. If there is interference in transmittingthrough a wall, it may be that the wall has reinforcing metal in its structure. Install another access pointto circumvent this problem.• Floors usually have metal girders and metal reinforcing struts that interfere with WLAN transmission.
