4.4 Radio CharacteristicsRadio Characteristics of USI 802.11b WLAN CF Cards may vary:• According to the country where the product was purchased.• According to the type of product that was purchased.Wireless communication is often subject to local radio regulations. Although“USI 802.11b WLAN CF Card” wireless networking products have been designedfor operation in the license-free 2.4 GHz band, local radio regulations mayimpose anumber of limitations to the use of wireless communication equipment.To comply with such regulations, USI 802.11b WLAN CF Cards are marketedwith dedicated channel-sets with a number of factory-programmed channelsidentified by the following acronyms:• ETS for countries that adhere to the regulations as defined by theEuropean Telecommunications Standards Institute (ETSI).• FCC for countries that adhere to the regulations as defined by the USFederal Communications Commission (FCC).• FR for France, and• JP for Japan.The acronym of the channel-set supported by your card is printed on a labelon the back-side of your USI 802.11b WLAN CF Card.Radio Characteristics USI 802.11b WLAN CF Card AR-F Frequency Band 2.4 GHz (2400-2500 MHz)North America (FCC) 11Europe (ETS) 13France (FR) 4Japan (JP) 1Number of selectablesub-channelsOther Countries: FCC 11, ETS 13Modulation TechniqueDirect Sequence Spread SpectrumCCK for High & Medium Transmit RateDQPSK for Standard Transmit Rate• DBPSK for Low Transmit RateSpreading 11-chip Barker SequenceBit Error Rate (BER) Better than 10 -5Nominal Output Power 15 dBm

Use on the supplied antenna. Unauthorized antenna, modification, orattachments could damage the transmitter and may violate FCC regulations.This device complies with Part 15 of the FCC Rules. Operation is subject to the followingtwo conditions:(1) This device may not cause harmful interference.(2) This device must accept any interference received, including interference that maycause undesired operation.
Basic TroubleshootingIf you cannot connect your USI 802.11b WLAN CF Card to the network, thefirst troubleshooting hint is to verify LED activity of the CF Card . The LEDsmay show the following behavior:• Power LED on, Transmit/Receive LED off • Power LED on, Transmit/Receive LED flickering • Both LEDs blink once every 10 seconds • Power LED is Flickering • No LED Activity If there is LED activity, run the Client Manager diagnostic tool on your stationto:• Run the Link Test to verify the quality of wireless network interfaceradio communications with the network. Power LED on, Transmit/Receive LED offThis LED status indicates normal operation:• The USI 802.11b CF WLAN Card is powered on • The Transmit/Receive LED indicates there is no activity on the wirelessnetwork. The absence of activity on the Wireless Network Interface might be related tohe fact that:• You moved out of Wireless Range of the Base Station(s) that couldprovide access to the selected network. • There are no Wireless Client Stations in the Wireless Range of yourcomputer to participate in the selected Peer-to-Peer Group. • The Base Station(s) that could provide access to the selected network has(have) a problem (e.g. power is off). Power LED on, Transmit/Receive LED flickeringThis LED status indicates normal operation:• The USI 802.11b WLAN CF Card is powered on • The Transmit/Receive LED indicates activity on the wireless network.
If the radio of your USI 802.11b WLAN CF Card seems to communicate withother radio devices, but does not succeed in actually connecting to thenetwork (i.e. the power and radio LED shows normal activity), you may needto verify whether your operating system installed the correct Network ProtocolSettings.Both LEDs blink once every 10 secondsThis LED indicates that the USI 802.11b WLAN CF Card is powered onand working properly, but it is not able to establish a wireless connectionto the wireless network. Possible causes might be:• Your wireless station is outside the Wireless Range of the BaseStation(s) that could provide you access to the selected network. • The Wireless Network Interface of your station has been configuredwith an incorrect Network Name and/or Encryption Key settings. • By mistake you selected a configuration profile on your wirelessstation, that does not belong to the wireless network that you wantto connect to. • The Base Station(s) that could provide access to the selectednetwork has (have) been configured to deny access to stations thatuse the value ANY as their Network Name. Contact your LAN Administrator for information about the correct values ofthe parameter settings that apply in your network.No LED ActivityIf there is absolutely no LED activity on the Power LED andReceive/Transmit LED of the USI 802.11b WLAN CF Card, this may bedue to one of the following reasons:• The USI 802.11b WLAN CF Card device is not properly connectedto your computer. • No driver was installed to allow communication between yourcomputer and the wireless network interface. Power LED is FlickeringA flickering Power LED identifies that you enabled the Card PowerManagement option for the USI 802.11b WLAN CF Card of a WirelessClient Station (Advanced Settings).
