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-freely. Using radio frequency (RF) technology, WLAN devices transmit and receive data over the air, minimizing 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 user’s guide will assist you in installing the WLAN USB Adapter. 6 2 Wireless LAN Basics Wireless LAN network defined by IEEE 802.11b standard committee could be Configure as:Ad Hoc wireless LAN orInfrastructure wireless LAN. Ad Hoc network is a group of notebooks with wireless LAN adapter, called a BSS (Basic Service Set). These notebooks use their wireless LAN adapter to communicate with each other directly. 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. 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, it’s recommend that you set it as “Infrastructure” mode to connect to the Internet. 7 3 Drivers and Utility Installation This section describes the procedures for installing the Wireless LAN USB…

FCC ID: RAFXWL-11BUZX Report No.920611R01B 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.

ADDRESS: 13F-4, No.738, Chung Cheng Road, Chung Ho City, Taipei Hsien, Taiwan, R.O.C. ISSUED BY: Advance Data Technology Corporation LAB LOCATION: 47 14th Lin, Chiapau Tsun, Linko, Taipei, Taiwan, R.O.C. 0528 ILAC MRA Lab Code: 200102-0 FCC ID: RAFXWL-11BUZX Report No: 920611R01B 2 RF Exposure Measurement (Portable Device) 1. Introduction In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC) calibrated for antenna measurement in ADT, and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis transmission formula is a far field assumption, the calculated result of that is an over-prediction for near field power density. We will take that as the worst case to specify the safety range. 2. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Average Time (minutes) (A)Limits For Occupational / Control Exposures 300-1500......F/3006 1500-100,000......56 (B)Limits For General Population / Uncontrolled Exposure 300-1500......F/15006 1500-100,000......1.030 F = Frequency in MHz FCC ID: RAFXWL-11BUZX Report No: 920611R01B 3 3. Friis Formula Friis transmission formula : Pd = (Pout*G) / (4*pi*r 2 ) where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the MPE value at distance r.
