Encryption On the Encryption screen, show in Fig 4-5, you can set the level of security with which you will be using the WLAN PC Card. Under the drop-down box, you can choose to have WEP encryption Disabled, 64-Bit, or 128- Bit Wired Equivalent Privacy (WEP) is an encryption scheme use to protect wireless data communi- cation. If you decide to use encryption, you can choose any of the available WEP keys (1 to 4). You also have option to select the WEP mode (Mandatory/optional). If you select “Mandatory”, then not only WEP will be used, but also any other station needs to use WEP encryption in order to establish a communication with your station. This requirement is in line with the IEEE 802.11b standard. If, on the other hand, you choose “Option”, then your station can communication with every other station regardless if they use WEP or not. The Disabled setting prevents the sharing of data with other computers on the WEP network. When Enable encryption for the WEP Key entry, enter the hexa- decimal number (the letters “A” through “F” and the numbers “0” through “9”) set by the other wireless WEP settings; these settings must be identical to the WEP encryption on all points in your wireless network in order to network to your WLAN PC Card. The security keys are four 10 digit key for the 64-Bit WEP setting and four 26 digit key for the 128-Bit WEP setting. Fig 4-5 15 NOTE: The WEP Key Entry must match the Key on all other devices on the wireless network or this device will be unable to transmit or receive data. 33 33 3 Advanced The Advanced screen (Fig 4-6) allows you to set Fragmentation Threshold, the RTS/CTS Threshold, and the Preamble Type. The Fragmentation Threshold Value indicates how much of the network resources is devoted to recovering packet errors. The value should remain at its default setting of 2,432. If you experience high packet error rates, you can decrease this value but it will likely decrease overall network performance. Only minor modifications of this value are recom- mended. Fig 4-6 For Authentication Type, you may choose between Open System or Shared Key. Shared Key is when both the sender and recipient share a secret key. Both units this key for an extended length of time, sometimes indefinitely. Any eavesdropper that discovers the key may decipher all packets unit the key is changed. Open System the default setting, is when the sender and the recipient do not share a secret key. Each party generates its own key-pair and asks the receiver to accept the (usually randomly) generated key. Once accepted, this key is use for short time only: then a new key is generated and agrees upon. 16 The About screen (Fig 4-7) shown the release information for the Driver Version, Firmware Version, Application Version, and MAC Address. User the “Exit” button in order to exit the application. About Fig 4-7 17 The RTS Threshold Value should remain at its default setting of 2,432. A preamble is a signal used to synchronize the transmission timing between two or more systems. A series of transmission pulses is sent before the data to indicate that “someone is about transmit data.” this ensures that systems receive the information correctly when the data transmission stars. The Preamble Type should be set to Short (if the network environment is “noisy”) or Long (if the environment is “clear”) Click Submit to complete the configuration. 18 How to Uninstall the configuration & Monitor Utility In order to uninstall the Configuration & Monitor Utility from Windows 95/98/ME, you can RUN Setup utility again then you will see Fig 4-7 then step by step remove all installed components. It is recommended to stop the WLAN adapter and “Exit” the application prior to staring the uninstallation procedure. Fig 4-8 Chapter 5: Installation Procedure Under Windows NT 4.0 (Only For PCMCIA) About Windows NT 4.0 Use the procedures described in this section to install and configure the WLAN adapter under MS Windows NT 4.0. Although Windows NT 4.0 are similar in appearance wit Windows 95/98/ME, and Windows 2000, they have different philosophy when installing a new hardware. Throughout this section it is assumed that you have basic working knowledge of Windows NT 4.0 and how to install new network cards on them. However, in this paragraph, some specific features of Windows NT 4.0 are briefly explained. Unlike Windows 95/98/ME, and Windows 2000. Windows NT 4.0 do not support the “Plug & Play” and “Hot Swapping” features. In Windows NT 4.0 you need to inform the operating system about the existence of the new card in order to star installing the driver. Also, if you want to swap cards, you need to restart the PC in order to recognize the card. Another difference between Windows 95/98/ME and Windows NT 4.0 is how these operating systems handle the “User Profiles” feature. Windows 2000 handle “User Profiles” in the same way as Windows NT 4.0. In Windows 95/98/ME, the “User Profiles” are use only in order to customize the appearance of the desktop between the different users. However, in Windows NT 4.0, “User Profiles” play the role of accounts and are associated with certain privileges on the machine. Therefore, we have different “User Profiles” (and privileges) for simple users, power users, and administrators. The privilege settings for each user are set in the “User Manager” program of Windows NT 4.0. Installing the Driver NOTE: In order to be able to install the WLAN adapter on to your PC running under Windows NT 4.0, you will need to log on as “Administrator”. Also to have at least NT Service Pack 4 installed. 33 33 3 First of all, in order to obtain the necessary privileges for the driver installation, you need to log on as Administrator to Windows NT 4.0. Since Windows NT 4.0 do not support “Plug & Play”, you must enable the detection of PC cards by the operating system by following the following procedure: 1. Click Start XSettingsXControl Panel. 2. Double click the “Devices” icon. 3. Select “PCMCIA” from …

Introduction 2.4 GHz frequency band is regarded specially as a dangerous band for its heating harmfulness to the human body. That’s why microwave oven is operating in this frequency band. The manufacturer whose product is working in this frequency band is obligatory to prove the harmfulness of his product. 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), and 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. 2. Classification The antenna of the product, under normal use condition, is at least 20 cm away from the body of the user. Warning statement for keeping 20 cm separation distance and the prohibition of operating next to a person has been printed on the users manual. So, this product is classified as the Mobile Device. 3. 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). FCC ID: IIO-0232USB611 ADT No.: 910814R07 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 30-30061.40.1631.06 300-1500......F/3006 1500-100,000......56 (B)Limits For General Population / Uncontrolled Exposure 30-30027.50.0730.230 300-1500......F/150030 1500-100,000......1.030 F = Frequency in MHz 4. 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 distance r where the MPE limit is reached. Ref. : David K.
