The Client Utility Program .......................................................................................9 5 1. Network Implementation Using The product There are two possible types of wireless network configurations using the product: (1) Infrastructure (wireless network using an Access Point) Using the Client/Server or Master/Slave concept, an Access Point is used to link a wired network with wireless clients. Not only can the wireless clients access the wired network but they can also access each other via the Access Point. Multiple Access Points can be used in the same infrastructure network in order to extend the wireless network range or share the workload of handling more wireless clients. (2) Ad-Hoc (wireless network not using an Access Point) Since there is no Access Point to act as a link to a wired network, wireless network nodes can only access each other but cannot access a wired network or the Internet. 2. Before Installation Package Contents Unpack and confirm that the following contents (in addition to this User Manual) are included: 11g WLAN USB Adapter (1 ea.) Installation CD (1 ea.) Quick Installation Guide (1 ea.) USB cable To Prepare Before Installation Ask your system administrator for the following information, which you may need to input during installation: 6 - Your SSID (group name of the wireless network) - If you are using a fixed IP address: IP address, gateway address, and subnet mask info. To use the Dual-band Wireless LAN USB Adapter, the device must be equipped with an internal or external USB slot. You should have the latest drivers and utility software for the product (please visit our website for the latest drivers and utility software). 3.…

FCC ID: SI5WUB200Z Report No.RF940324L03 Operational Description This device is a Wireless 802.11g USB Adapter which operates in the 2.4GHz frequency spectrum with throughput of up to 54Mbps which OFDM technique will be applied. If the signal to noise radio is too poor which could not support 54Mbps, the 11Mbps data rate with DSSS technique will be applied. The transmitter of the EUT is powered by host equipment. The antenna used in this product is Printed antenna without connector. The other instruction, please have a look at the users manual.

FCC ID: SI5WUB200Z Report No: SA940324L03 1 RF EXPOSURE REPORT REPORT NO.: SA940324L03 MODEL NO.: WUB-200Z ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT: U-MEDIA Communications, Inc. ADDRESS: 9F, No.1, Jin-shan 7th St., Hsinchu 300, Taiwan, R.O.C. ISSUED BY: Advance Data Technology Corporation LAB ADDRESS: No. 47, 14th Ling, Chia Pau Tsuen, Lin Kou Hsiang 244, Taipei Hsien, Taiwan, R.O.C. TEST LOCATION: No. 19, Hwa Ya 2nd Rd., Wen Hwa Tsuen, Kwei Shan Hsiang, Taoyuan Hsien 333, Taiwan, R.O.C. FCC ID: SI5WUB200Z Report No: SA940324L03 2 RF Exposure Measurement (Mobile 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: SI5WUB200Z Report No: SA940324L03 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. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 4. EUT Operating condition The software provided by Manufacturer enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 5. Classification This device is not fixed inside the host equipment, it is connected with host through wire. So it is easy to be re-located in the place where at least 20cm far away from the body of the user. Warning statement to the user for keeping at least 20cm or more separation distance with the antenna should be included in users manual. So, this device is classified as Mobile Device.
