This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The 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 instruction, may cause harmful interference to radio communication. However, there is no grantee that interference will not occur in a particular installation. If this equipment dose causes 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. Notice: The Part 15 radio device operates on a non-interference basis with other devices operating at this frequency. Any changes or modification not expressly approved by the party responsible could void the user’s authority to operate the device. "ASUSTeK COMPUTER INC. declare that WL-161 (802.11b USB Pen Type WLAN Adapter) is limited in CH1~CH11 by specified firmware controlled in USA." 5 REGULATORY INFORMATION ASUS WL-161 WLAN Adapter must be installed and used in strict accordance with the instructions. This device complies with the following radio frequency and safety standards. USA - Federal Communications Commission (FCC) This device complies with Part 15 of 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 that may cause undesired operation.

Introduction Thank you for purchasing ASUS WL-161 WLAN Adapter. You are about to install a networking system that is not only fast and powerful, but also easy to set up and simple to maintain. In a short time you and those in your network will be able to share a local printer and files, access the Internet, and roam about the office wire-free. Using radio frequency (RF) technology, WLANs transmit and receive data over the air, mizing the need for wired connections. Thus, WLANs combine data connectivity with user mobility, and, through simplified configuration, enable movable LANs. This wireless networking solution has been designed for both large and small businesses, and it is scalable so that you can easily add more users and new network features as your business grows. This manual will assist you in the installing ASUS WL-161 WLAN Adapter. 7 2. Wireless LAN basics Wireless LAN network defined by IEEE 802.11b standard committee could be configured as: • Ad Hoc wireless LAN, or • Infrastructure wireless LAN. Ad Hoc network is a group of notebooks with wireless LAN PC card called a BSS (Basic Service Set). These notebooks use their wireless LAN PC cards to communicate with each other, and notebooks cannot connect to the Internet. Figure 2-1 Ad Hoc wireless network The most obvious differentiation between Infrastructure wireless network and Ad Hoc wireless network is that the notebooks in Infrastructure wireless network can make use of the resource in the Internet through Access Point. STA 3 STA 1 STA 2 Access Point Internet Figure 2-2 Infrastructure wireless network To set up your notebook’s network as the type of “Ad Hoc” or “Infrastructure” wireless network depends completely on your requirement. Generally, if your network environment has an Access Point, we recommend that you set it as “Infrastructure” to connect to the Internet. STA 1 STA 2 STA 3 8 3. Windows Installation Before You Start To use the ASUS WL-161 WLAN Adapter with a computing device, the ASUS WL-161 WLAN Adapter must be equipped with an USB 1.1 or 2.0 Interface. All drivers and supporting software for the ASUS WL-161 WLAN Adapter must be loaded and configured. Ask your system abstractor for the following information, which you may need to provide …

FCC ID: MSQWL161 Report No. RF930302R04A Operational Description The transmitter of the EUT is powered by host equipment. The antenna used in this product is Chip antenna without antenna connector. The other instruction, please have a look at the users manual. DSSS Information This device is Direct Sequence Spread Spectrum, the data is mixed by pseudorandom code which is an orthogonal code. The mixed data is digital modulated by BPSK and QPSK technique depends on the data rates. The CCK coding is applied for increasing the data rate, and also the processing gain will be increased. The bit rates are 1,2,5.5,11Mbps, the symbol rates are 1,1,1.375,1.375Mbps, the chip rates are always 11Mbps. So, the Chip/symbol is 11,11,8 and 8 respectively. Although is higher bit rate, the processing gain is lower than 10, but the CCK coding used in higher bit rate will provide 2.2dB coding gain.
