To manually enter the port information: 1Specify the trigger port (the one used by the application when it is initialized) in the Trigger Port column, and specify whether the trigger is TCP or UDP. 2Specify the Public Ports used by the application, that will need to be opened up in the firewall for the application to work properly. Also specify whether these ports are TCP or UDP. 3Check the Enabled checkbox, then click Apply. 72CHAPTER 5: CONFIGURING THE ROUTER Virtual ServersThe Virtual servers feature allows you to route external (Internet) calls for services such as a web server (port 80), FTP server (Port 21), or other applications through your Router to your internal network. Since your internal computers are protected by a firewall, machines from the Internet cannot get to them because they cannot be 'seen'. If you need to configure the Virtual Server function for a specific application, you will need to contact the application vendor to find out which port settings you need. The maximum number of virtual servers that can be configured is 20. Figure 57 Virtual Servers Screen A list of popular servers has been included to choose from. Select the server from the Popular servers drop-down menu. Then click Add, your selection will be added to the table. If the server that you want to use is not listed in the drop-down menu, you can manually add the virtual server to the table. To manually configure your virtual servers: 1Enter the IP address, and the description in the spaces provided for the internal machine. 2Select the protocol type (TCP, UDP, or both TCP and UDP) from the drop-down menu. 3Specify the public port that will be seen by clients on the Internet, and the LAN port which the traffic will be routed to. Firewall73 4You can enable or disable each Virtual Server entry by checking or unchecking the appropriate Enabled checkbox. 5Click Apply to save the changes for each Virtual Server entry. DMZIf you have a client PC that cannot run an Internet application properly from behind the firewall, you can open the client up to unrestricted two-way Internet access. This may be necessary if the NAT feature is causing problems with an application such as a game or video conferencing application. Figure 58 DMZ Screen Use this feature on a temporary basis. The computer in the DMZ is not protected from hacker attacks. To put a computer in the DMZ: 1Check the Enable 1-to-1 NAT checkbox. 2Enter the last digits of the LAN IP address in the Client PC IP Address field. Enter the IP address (if known) that will be accessing the DMZ PC into the Public IP Address field, so that only the computer on the Internet at this address can access the DMZ PC without firewall protection. If the IP address is not known, or if more than one PC on the Internet will need to access the DMZ PC, then set the Public IP Address to 0.0.0.0. 3Click Apply. 74CHAPTER 5: CONFIGURING THE ROUTER Schedule RuleThe Router can be configured to restrict access to the Internet, email or other network services at specific days and times.

Introduction The EUT operates in the 2.4GHz ISM band. Due to the EUT (include antenna) at its normal operation distance is at least 20 cm from the human body, the EUT was defined as a Mobile Device. The reason to do the MPE Evaluation is to avoid the RF hazard to human body. The maximum output power and gain of the antenna were used to calculate the limited Power density (S) at 20cm distance away from the product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. 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 30-300 61.4 0.163 1.0 6 300-1500 - - F/300 6 1500-100,000 - - 5 6 (B) Limits for General Population / Uncontrolled Exposure 30-300 27.5 0.073 0.2 30 300-1500 - - F/1500 30 1500-100,000 - - 1.0 30 F= Frequency in MHz FCC ID. : RAXAR4505NW Report No.: EME-060250 Page 5 of 5 3. RF Exposure calculations From §FCC 1.1310 table 1, the maximum permissible RF exposure for an uncontrolled environment is 1mW/(cm 2 ) Power density (S) is calculated by the following formula: S = (P * G)/4πR 2 where, S = Power density (mW/cm 2 ) P = Output power to antenna (mW) R = Distance between radiating structure and observation point (cm) G = Gain of antenna in numeric π = 3.1416 Example: Assume a mobile device operates at 2412MHz and its maximum output power is 50mW, and the maximum gain of antenna is 1 (numeric) /0dBi. then the power density (S) = (50 * 1)/4*π*20 2 = 0.00995 (mW/cm 2 ) 4.
