WIRELESS 4-25 Wireless The Barricade also operates as a wireless-to-wired bridge, allowing wireless computers to access resources available on the wired LAN, and to access the Internet. To configure the Barricade as a wireless access point for wireless clients (either stationary or roaming), all you need to do is enable the wireless function, define the radio channel, the domain identifier, and the encryption options. Check Enable and click APPLY. CONFIGURING THE BARRICADE 4-26 Channel and SSID You must specify a common radio channel and SSID (Service Set ID) to be used by the Barricade Wireless Router and all of your wireless clients. Be sure you configure all of your clients to the same values. ParameterDescription ESSIDExtended Service Set ID. The ESSID must be the same on the Barricade and all of its wireless clients. Transmission Rate The default is Fully Automatic. The transmission rate is automatically adjusted based on the receiving data error rate. Usually the connection quality will vary depending on the distance between the wireless router and wireless adapter. You can also select a lower transmission data rate to maximize the radio communication range. WIRELESS 4-27 Basic RateThe highest rate specified will be the rate that the Barricade will use when transmitting broadcast/multicast and management frames. Available options are: All (1, 2, 5.5, and 11Mbps), and 1, 2Mbps (default is 1, 2Mbps). ChannelThe radio channel must be the same on the Barricade and all of your wireless clients. The Barricade will automatically assign itself a radio channel, or you may select one manually. ParameterDescription CONFIGURING THE BARRICADE 4-28 Encryption If you are transmitting sensitive data across wireless channels, you should enable encryption. You must use the same set of encryption keys for the Barricade and all of the wireless clients. Choose between standard 64-bit WEP (Wired Equivalent Privacy) or the more robust 128-bit encryption. You may automatically generate encryption keys or manually enter the keys. For automatic 64-bit security, enter a passphrase and click Generate, four keys will be generated. Choose a key from the drop-down list or accept the default key. Automatic 128-bit security generates a single key. Note: The passphrase can consist of up to 32 alphanumeric characters. To manually configure the keys, enter five hexadecimal pairs of digits for each 64-bit key, or enter 13 pairs for the single 128-bit key. (A hexadecimal digit is a number or letter in the range 0-9 or A-F.) Note that WEP protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet. WIRELESS 4-29 MAC Address Filtering Client computers can be filtered using the unique MAC address of their IEEE 802.11 network card. To secure an access point using MAC address filtering, you must enter a list of allowed/denied client MAC addresses into the filtering table. (See “Finding the MAC address of a Network Card” on page 4-57.) ParameterDescription Filtering DisableDisables MAC address filtering. EnableEnables MAC address filtering. Setting PermissionsAllows only devices with their MAC address in the list to connect to the Barricade. ProhibitionDenies access to the Barricade from devices with their MAC address in the list. CONFIGURING THE BARRICADE 4-30 NAT Some applications require multiple connections, such as Internet gaming, videoconferencing, and Internet telephony. These applications may not work when Network Address Translation (NAT) is enabled. If you need to run applications that require multiple connections, use these pages to specify the additional public ports to be opened for each application. Address Mapping Allows one or more public IP addresses to be shared by multiple internal users. This also hides the internal network for increased privacy and security. Enter the Public IP address you wish to share into the Global IP field. Enter a range of internal IPs that will share the global IP into the from field. NAT 4-31 Virtual Server If you configure the Barricade as a virtual server, remote users accessing services such as Web or FTP at your local site via public IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the Barricade redirects the external service request to the appropriate server (located at another internal IP address). If you configure the Barricade as a virtual server, remote users accessing services such as Web or FTP at your local site via public IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the Barricade redirects the external service request to the appropriate server (located at another internal IP address). CONFIGURING THE BARRICADE 4-32 For example, if you set Type/Public Port to TCP/80 (HTTP or Web) and the Private IP/Port to 192.168.2.2/80, then all HTTP requests from outside users will be transferred to 192.168.2.2 on port 80. Therefore, by just entering the IP Address provided by the ISP, Internet users can access the service they need at the local address to which you redirect them. The more common TCP service ports include: HTTP: 80, FTP: 21, Telnet: 23, and POP3: 110. A list of ports is maintained at the following link: http://www.iana.org/assignments/port-numbers. Note:The WAN interface should have a fixed IP address to best utilize this function. If your ISP only provides dynamic IP addresses, a search for “free dynamic IP” on any major search engine will turn up tools that will allow you to use the same domain name even though your IP address changes each time you log into the ISP. ROUTING SYSTEM 4-33 Routing System These pages define routing related parameters, including static routes and RIP (Routing Information Protocol) parameters. Static Route Click A…

DownstreamMaximum data rate downstream. Operation Data/Defect Indication Noise Margin UpstreamMinimum noise margin upstream. DownstreamMinimum noise margin downstream. Output PowerMaximum fluctuation in the output power. Attenuation UpstreamMaximum reduction in the strength of the upstream signal. DownstreamMaximum reduction in the strength of the downstream signal. Fast Path FEC Correction There are two latency paths that may be used: fast and interleaved. For either path a forward error correction (FEC) scheme is employed to ensure higher data integrity. For maximum noise immunity, an interleaver may be used to supplement FEC. Interleaved Path FEC Correction An interleaver is basically a buffer used to introduce a delay, allowing for additional error correction techniques to handle noise. Interleaving slows the data flow and may not be optimal for real-time signals such as video transmission. Fast Path CRC Error Indicates the number of Fast Path Cyclic Redundancy Check errors. Interleaved Path CRC Error Indicates the number of Interleaved Path Cyclic Redundancy Check errors. Loss of Signal Defect Momentary signal discontinuities. Loss of Frame Defect Failures due to loss of frames. CONFIGURING THE BARRICADE 4-52 Loss of Power Defect Failures due to loss of power. Fast Path HEC Error Fast Path Header Error Concealment errors. Interleaved Path HEC Error Interleaved Path Header Error Concealment errors. Statistics(Superframes represent the highest level of data presentation. Each superframe contains regular ADSL frames, one of which is used to provide superframe synchronization, identifying the start of a superframe. Some of the remaining frames are also used for special functions.) Received Superframes Interleaved Number of interleaved superframes received.

Lab Code: 200376-0 FCC ID: HED7404WBRAACC Report No.: 911125H02 RF Exposure Measurement 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: HED7404WBRAACC Report No.: 911125H02 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 Pd is the limit of MPE, 1 mW/cm 2 . 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. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq.
