If the Wireless-G PCI Adapter does not function after attempting the above steps, remove the adapter and do the following: •Uninstall the driver software from your PC. •Restart your PC and repeat the hardware and software installation as specified in this User Guide. 2. I cannot communicate with the other computers linked via Ethernet in the Infrastructure configuration. •Make sure that the PC to which the Wireless-G PCI Adapter is associated is powered on. •Make sure that your Wireless-G PCI Adapter is configured on the same channel and with the same security options as with the other computers in the Infrastructure configuration. 27 Appendix A: Troubleshooting Frequently Asked Questions Wireless-G PCI Adapter Frequently Asked Questions Can I run an application from a remote computer over the wireless network? This will depend on whether or not the application is designed to be used over a network. Consult the application’s user guide to determine if it supports operation over a network. Can I play computer games with other members of the wireless network? Yes, as long as the game supports multiple players over a LAN (local area network). Refer to the game’s user guide for more information. What is the IEEE 802.11b standard? It is one of the IEEE standards for wireless networks. The 802.11b standard allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11b standard. The 802.11b standard states a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz. What IEEE 802.11b features are supported? The product supports the following IEEE 802.11b functions: •CSMA/CA plus Acknowledge protocol •Multi-Channel Roaming •Automatic Rate Selection •RTS/CTS feature •Fragmentation •Power Management What is ad-hoc mode? When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to communicate directly with each other. The ad-hoc wireless network will not communicate with any wired network. What is infrastructure mode? When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with a wired network through a wireless access point. What is roaming? Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout an area greater than that covered by a single access point. Before using the roaming function, the workstation must make sure that it is the same channel number with the access point of dedicated coverage area. To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each node and access point, for example, must always acknowledge receipt of each message. Each node must 28 Appendix A: Troubleshooting Frequently Asked Questions Wireless-G PCI Adapter maintain contact with the wireless network even when not actually transmitting data. Achieving these functions simultaneously requires a dynamic RF networking technology that links access points and nodes. In such a system, the user’s end node undertakes a search for the best possible access to the system. First, it evaluates such factors as signal strength and quality, as well as the message load currently being carried by each access point and the distance of each access point to the wired backbone. Based on that information, the node next selects the right access point and registers its address. Communications between end node and host computer can then be transmitted up and down the backbone. As the user moves on, the end node’s RF transmitter regularly checks the system to determine whether it is in touch with the original access point or whether it should seek a new one. When a node no longer receives acknowledgment from its original access point, it undertakes a new search. Upon finding a new access point, it then re-registers, and the communication process continues. What is ISM band? The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in the hands of users around the globe. What is Spread Spectrum? Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband transmission, but the trade-off produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows…

ISSUED BY: Advance Data Technology Corporation TEST LOCATION: No. 19, Hwa Ya 2 nd Rd., Wen Hwa Tsuen, Kwei Shan Hsiang, Taoyuan Hsien 333, Taiwan, R.O.C. FCC ID: Q87-HGA5S-4 Report No: SA931009L02 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: Q87-HGA5S-4 Report No: SA931009L02 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 20cm.
