EmulationEngine 11a/b/g User's Guide 080104 5-25 Traffic Source: Select Internal or External from the list box. In Internal mode, traffic is generated internally by each vSTA using ICMP Echo (Ping) Request/Reply packets. In External mode, packets coming into the EmulationEngine over 802.3 are mapped to virtual stations by source IP or MAC address and forwarded via 802.11. Packets coming back via 802.11 are remapped to the originating MAC address. Layer 2/Layer 3: If External is selected in the Traffic Source field, select one of these radio buttons to identify the external frames to be captured. If Layer 2 is selected, frames will be captured based on the source 802.3 MAC address. If Layer 3 is selected, frames will be captured based on the source IP address. For vSTAs configured at layer 3, IP and ARP packets generated from this host that contain the virtual station's IP address as a source will be translated at the MAC layer to appear as if sourced from the virtual station's MAC address. Target IP Address: Enter the target IP address where ICMP Echo (Ping) Requests should be sent. The default IP address (0.0.0.0) shown in this Communication Machinery Corporation (CMC) 5-26 080104 example dialog must be replaced by a valid IP address (e.g., 10.10.10.19). Packet Length: Specify the size of the ping data buffer (64...1024). The default is 1024. Count: Specify the total number of pings to be sent: 0...10000 (0=None). !" Click “Create” to create the group. !" Click “Cancel” to exit this dialog. vSTA->New Group->Runtime The Runtime section of the New Emulation Group dialog allows you to run a virtual station’s test multiple times. This is only applicable to internal traffic generation. After each iteration of a test, the state of the virtual station can be set to a “base state”. A user-defined delay between successive iterations is defined in milliseconds. Optionally, any results collected for the virtual station can be cleared at the start of each iteration. EmulationEngine 11a/b/g User's Guide 080104 5-27 Number of Iterations: Enter the number of times (1...10000) to repeat the virtual station’s task (Ping) or select the Infinite checkbox to continuously iterate indefinitely. Iteration Delay: Enter the delay (in milliseconds) to be introduced between iterations of the test. It can be set to a value in the range: 0...300000 milliseconds (5 minutes). Before Running Next Iteration->Reset vSTA State to: Select a state from the list box. Each virtual station in this group will be reset to the selected state (initialized, authenticated, or associated) at the end of each iteration. Before Running Next Iteration->Clear vSTA Results: Select this check box to clear test results before successive iterations of the test. RTS Threshold: Enter a value in the range 1...2346 to define the RTS threshold for the virtual station(s) in this group. Any frame to be transmitted by a virtual station that exceeds the RTS threshold, will require a successful RTS/CTS frame exchange before the frame is transmitted. The minimum value (1) effectively requires RTS/CTS for all transmit frames. The maximum value (2346) is the maximum 802.11 frame size and effectively disables RTS. Fragmentation Threshold: Enter a value in the range 256...2346 to define the fragmentation threshold for the virtual station(s) in this group. The fragmentation threshold will limit the number of bytes in any 802.11 frame transmitted by the virtual station(s). If this field is set to 2346 (i.e., the maximum 802.11 frame size), fragmentation is effectively disabled. !" Click “Create” to create the group. !" Click “Cancel” to close this dialog. vSTA->New Group->On Error The On Error section of the New Emulation Group dialog defines whether virtual stations should reconnect to the System Under Test during a test if the system de-authenticates or disassociates a virtual station. Communication Machinery Corporation (CMC) 5-28 080104 Persist: Select this checkbox to enable or disable persistence. When enabled, virtual stations in this group will remain persistent (connected) if the System Under Test de-authenticates or disassociates. If the EmulationEngine loses connection to a System Under Test, persistence will allow it to recover and continue the test at the point where it was interrupted. For example, if a virtual station is in a run or associated state and an 802.11 management frame (deauth or disassoc) is sent by the System Under Test and received by the EmulationEngine, the virtual station will attempt to return to the state it was in before the management frame was received. If the virtual station was running a ping test, the ping test will continue. If it was in an associated state, the virtual station will reissue the associate request. Retries: This field specifies the number of times the EmulationEngine should issue authentication and association requests before failing the operation. It can be a value in the range 0...10. EmulationEngine 11a/b/g User's Guide 080104 5-29 Timeout: This field specifies the timeout value (in milliseconds) for authentication and association requests. It can be set to a value in the range 250...60000 milliseconds (1 minute). !" Click “Create” to create the group. !" Click “Cancel” to close this dialog. vSTA->New Group->Encryption This section of the New Group dialog defines whether the virtual station will use encryption, the associated cipher to be used and the type of authentication (Open System or Shared Key) to be used for authenticating with the System Under Test. NOTE: The four shared keys for Wired Equivalency Privacy (WEP) encryption must be defined in the Encryption Defaults dialog in the Configuration side bar. Encryption: Select this checkbox to enable/disable encryption. Communication Machinery Corporation (CMC) 5-30 080104 Authentication: Select the authentication type: Open System or Shared Key. Cipher Selection: Reserved for future use. WEP is the only supported selection in this release. Shared …

EmulationEngine 11a/b/g User's Guide 080104 6-1 CHAPTER 6: The Command Line Interface (CLI) The CLI can be used to display and modify the configuration of the EmulationEngine from a PC that is connected via Telnet or the serial port. The CLI also includes commands to configure and run virtual stations, display statistics, and to access the System Under Test. The EmulationEngine maintains statistics and event log files that you can configure and display using CLI commands. CLI Usage Notes 1) CLI commands are not case sensitive (e.g., "set Date" is the same as "set date"). 2) You do not need to enter the entire command string to execute a command. Only the number of unique characters required to identify the command are needed (e.g., "se da" will execute the "set date" command because there are no other CLI commands that begin with “se” and no other set objects that begin with "da"). 3) Some parameters can be assigned very large values in the range: 0...2,147,483,647. Do not enter commas (,) for values larger than 999 (e.g., use 1000 rather than 1,000). 4) It is very important to keep a printed record of configuration parameters. See "Configuration Records" in Chapter 9. User Log-In The EE login prompt is displayed after you successfully establish a connection to the EmulationEngine. See “Initial Setup” in Chapter 4. When you have successfully established this connection, the CLI prompts you to enter a log in name and password. EE login: Admin Password: ** The default log in user name is "Admin". The default password is "EE". Both entries are case sensitive (i.e., the default user name is "Admin", not "admin"). After you enter a valid user name and password, the CLI displays a version banner, the current system time and status, and a CLI prompt. Communication Machinery Corporation EmulationEngine(tm) 11a/b/g Rev 2.3.0.a1 System date & time: THU JAN 01 00:00:20 2004 Use the "set date" or "set time" command to adjust EmulationEngine 11a/b/g software version 2.3.0.a1 WLAN mode .................... 802.11a WLAN MAC address ............. 00:02:8a:b6:1e:c9 WLAN address mask ............ ff:ff:ff:ff:00:00 LAN MAC address .............. 00:0b:16:00:00:57 BSSID of System Under Test ... 00:04:e2:38:a7:9c EE-SUT connection status .....

Communication Machinery Corporation (CMC) 6-2 080104 NOTE: If the CLI displays the message “This EmulationEngine has not been Node Locked” after you enter the EE login name and password, see “Missing Key File” in Chapter 9, Troubleshooting. User Log-Off Use the quit command to log off from the CLI: CMC_EE -> quit After log-off, you must reopen the telnet connection to log in to the CLI. CLI Commands The “help” command will display a list of all CLI commands. Example: CMC_EE -> help List of EmulationEngine CLI commands: assoc -- Associate a vSTA with the SUT auth -- Authenticate a vSTA with the SUT acquireip -- Acquire an IP address for a vSTA releaseip -- Release a vSTA's IP address autoconf -- Autoconfig-init-auth-assoc N vSTAs autorun -- Run N configured/associated vSTAs clear bssid -- Clear BSSID for System Under Test clear evlog -- Clear event log file or buffer clear group -- Clear vSTA group data clear sntpserver -- Clear SNTP/NTP server IP address clear systemname -- Clear the EmulationEngine system name clear vsta -- Clear vSTA data conf -- Configure a vSTA deauth -- Deauthenticate a vSTA del group -- Delete a vSTA group del key -- Delete Encryption key del statfile -- Delete a vSTA statistics file del summfile -- Delete a vSTA statistics summary file del vsta -- Delete a vSTA disassoc -- Disassociate a vSTA exec -- Execute a command file ftp -- Software update via FTP get association -- Display Association Table get basic11b -- Display Basic 11b Rates get bssid -- Display BSSID of System Under Test get bsslist -- Display list of discovered BSSIDs get channel -- Display Radio Channel get config -- Display current EmulationEngine configuration get countrycode -- Display Country Code get ctsmode -- Display CTS mode (11g) get ctsrate -- Display CTS rate (11g) get ctstype -- Display CTS type (11g) get eemac -- Display Wireless LAN MAC Address get eemask -- Display Wireless LAN Address Mask get eestatus -- Display EmulationEngine status get evlog -- Display event log data get features -- Display authorized features get frequency -- Display Radio Frequency (MHz) get gateway -- Display Gateway IP Address get group -- Display information for a vSTA group get hardware -- Display Hardware Revisions get ipaddr -- Display IP Address get ipmask -- Display IP Subnet Mask get key -- Display Encryption Key EmulationEngine 11a/b/g User's Guide 080104 6-3 get keyentrymethod -- Display Encryption Key Entry Method get login -- Display Login User Name get pmmode -- Display Power Management Mode get power -- Display Transmit Power Setting get psinterval -- Display Power Save Listen Interval get rate -- Display Data Rate get shortpreamble -- Display Short Preamble (11b/11g) Usage get shortslottime -- Display Short Slot Time (11g) Usage get sntpserver -- Display SNTP/NTP Server IP Address get ssid -- Display Service Set ID get statfile -- Display vSTA statistics from file get station -- Display Station Status get summfile -- Display vSTA statistics summary from file get systemname -- Display the EmulationEngine system name get telnet -- Display Telnet Mode get tzone -- Display Time Zone Setting get uptime -- Display UpTime get version -- Display Firmware Version get vsta -- Display vSTA information get wirelessmode -- Display Wireless LAN Mode halt -- Halt a running vSTA help -- Display CLI Command List history -- Display the command line history init -- Initialize a configured vSTA join -- Join the EE with the System Under Test ping -- Ping quit -- Logoff reboot -- Reboot the EmulationEngine reset eemac -- R…

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…
