Federal Communication Commission Interference State-ment 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 installa-tion. 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 interfer-ence will not occur in a particular installation. If this equipment does cause harmful interference to radio or televi-sion 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.

WLAN Mini module quick guide 2 What is Wireless LAN? Wireless Local Area Network (WLAN) systems offer a great num-ber of advantages over traditional wired systems. WLANs are flexible and easy to setup and manage. They are also more eco-nomical than wired LAN systems. Using radio frequency (RF) technology, WLANs transmit and re-ceive data through the air. WLANs combine data connectivity with user mobility. For example, users can roam from a confer-ence 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 real-time information anywhere in their organization, providing service opportunities that are impossible with wired net-works. • Ease of Installation: Installing is easy for novice and ex-pert users alike, eliminating the need to install network cables in walls and ceilings. • Scalability: WLANs can be configured in a variety of to-pologies to adapt to specific applications and installations. Configurations are easily changed and range from peer-to-peer networks suitable for a small number of users to full infrastructure networks of thousands of users roaming over a broad area.
—Introduction 3 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 net-work 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 network-ing in that it includes an access point. Unlike the ad-hoc 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 wire-less 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 commu-nicate 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.
WLAN Mini module quick guide 4 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.
