USER’S MANUAL OF X-Micro WLAN 11b ACCESS POINT Version: 2.0 4 Frequently Asked Questions (FAQ) 4.1 What and how to find my PC’s IP and MAC address? IP address is the identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol route messages based on the IP address of the destination. The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255. For example, 191.168.1.254 could be an IP address. The MAC (Media Access Control) address is your computer's unique hardware number. (On an Ethernet LAN, it's the same as your Ethernet address.) When you're connected to the Internet from your computer (or host as the Internet protocol thinks of it), a correspondence table relates your IP address to your computer's physical (MAC) address on the LAN. To find your PC’s IP and MAC address, 9 Open the Command program in the Microsoft Windows. 9 Type in ipconfig /all then press the Enter button. ¾ Your PC’s IP address is the one entitled IP Address and your PC’s MAC address is the one entitled Physical Address. 4.2 What is Wireless LAN? A wireless LAN (WLAN) is a network that allows access to Internet without the need for any wired connections to the user’s machine. 4.3 What are ISM bands? ISM stands for Industrial, Scientific and Medical; radio frequency bands that the Federal Communications Commission (FCC) authorized for wireless LANs. The ISM bands are located at 915 +/- 13 MHz, 2450 +/- 50 MHz and 5800 +/- 75 MHz. 4.4 How does wireless networking work? The 802.11 standard define two modes: infrastructure mode and ad hoc mode. In infrastructure mode, the wireless network consists of at least one access point connected to the wired network infrastructure and a set of wireless end stations. This configuration is called a Basic Service Set (BSS). An Extended Service Set (ESS) is a set of two or more BSSs forming a single subnetwork. Since most corporate WLANs require access 19 USER’S MANUAL OF X-Micro WLAN 11b ACCESS POINT Version: 2.0 to the wired LAN for services (file servers, printers, Internet links) they will operate in infrastructure mode. Example 1: wireless Infrastructure Mode Ad hoc mode (also called peer-to-peer mode or an Independent Basic Service Set, or IBSS) is simply a set of 802.11 wireless stations that communicate directly with one another without using an access point or any connection to a wired network. This mode is useful for quickly and easily setting up a wireless network anywhere that a wireless infrastructure does not exist or is not required for services, such as a hotel room, convention center, or airport, or where access to the wired network is barred (such as for consultants at a client site). Example 2: wireless Ad Hoc Mode 4.5 What is BSSID? A six-byte address that distinguishes a particular a particular access point from others. Also know as just SSID. Serves as a network ID or name. 4.6 What is ESSID? The Extended Service Set ID (ESSID) is the name of the network you want to access. It is used to identify different wireless networks. 20 USER’S MANUAL OF X-Micro WLAN 11b ACCESS POINT Version: 2.0 4.7 What are potential factors that may causes interference? Factors of interference: ¾ Obstacles: walls, ceilings, furniture... etc. ¾ Building Materials: metal door, aluminum studs. ¾ Electrical devices: microwaves, monitors and electrical motors. Solutions to overcome the interferences: 9 Minimizing the number of walls and ceilings. 9 Position the WLAN antenna for best reception. 9 Keep WLAN devices away from other electrical devices, eg: microwaves, monitors, electric motors, ... etc. 9 Add additional WLAN Access Points if necessary. 4.8 What are the Open System and Shared Key authentications? IEEE 802.11 supports two subtypes of network authentication services: open system and shared key. Under open system authentication, any wireless station can request authentication. The station that needs to authenticate with another wireless station sends an authentication management frame that contains the identity of the sending station. The receiving station then returns a frame that indicates whether it recognizes the sending station. Under shared key authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11 wireless network communications channel. 4.9 What is WEP? An optional IEEE 802.11 function that offers frame transmission privacy similar to a wired network. The Wired Equivalent Privacy generates secret shared encryption keys that both source and destination stations can use to alert frame bits to avoid disclosure to eavesdroppers. WEP relies on a secret key that is shared between a mobile station (e.g. a laptop with a wireless Ethernet card) and an access point (i.e. a base station). The secret key is used to encrypt packets before they are transmitted, and an integrity check is used to ensure that packets are not modified in transit. 4.10 What is Fragment Threshold? The proposed protocol uses the frame fragmentation mechanism defined in IEEE 802.11 to achieve parallel transmissions. A large data frame is fragmented into several 21 USER’S MANUAL OF X-Micro WLAN 11b ACCESS POINT Version: 2.0 fragments each of size equal to fragment threshold. By tuning the fragment threshold value, we can get varying fragment sizes. The determination of an efficient fragment threshold is an important issue in this scheme. If the fragment threshold is small, the overlap part of the master and parallel transmissions is large. This means the spatial reuse ratio of parallel transmissions is high. In contrast, with a large fragment threshold, the overlap is small and the spatial reuse ratio is low. However high fragment threshold leads to low fragment overhead. Hence there is a trade-off between spatial re-use and fragment overhead. Fragment threshold is the maximum packet size used for fragmentation. Packets …

Dear Tim: Would you mind to help us to check why the FRN no. is not valid. On the website, it is existed, and our client have no idea what is the matter. And we revised the block. And about the comment 4, the card is an coverter, it is used to connect PC and the EUT. And about the comment 5, we used the more worst situation to calculate it. And the error on the plot shows no more than 4dB, but the restrict band is under more than 4dB. So do you think we really need to change the plot. Here is the declaration letter. (See attached file: Declaration form.pdf) Thank you for your kind assistance.

FCC ID: RAFXWL-11BARG Report No. RF920916R02A Operational Description The transmitter of the EUT is powered by power adapter. The antenna used in this product is diople antenna without antenna connector. Under normal use condition, the user has to keep at least 20 cm separation distance between radiator and the body of the user. 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 235, R.O.C. ISSUED BY: Advance Data Technology Corporation LAB LOCATION: 47 14th Lin, Chiapau Tsun, Linko, Taipei, Taiwan, R.O.C. FCC ID: RAFXWL-11BARG Report No: RF920916R02A 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: RAFXWL-11BARG Report No: RF920916R02A 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.

(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, for normal use, 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.
