System Requirements • Laptop/ PC containing: • 32-bit CardBus slot (or Desktop PC with PC Card-PCI adapter) • Mini PCI • 32 MB memory or greater • 300 MHz processor or higher PRELIMINARY Atheros Communications, Inc. Page 3 COMPANY CONFIDENTIAL February 2005 Microsoft Windows 2000, Windows Millennium Edition, Windows 98 Second Edition, Windows XP, or Windows NT 4.0 (with Service Pack 6) Profile Management Configure the wireless network adapter (wireless card) from the Profile Management tab of the Atheros Client Utility. • Add a profile • Edit a profile • Import a Profile • Export a Profile • Order profiles • Switch to a different profile • Remove a profile • Connect to a Different Network The wireless network adapter works in either infrastructure mode (which uses an access point) or ad hoc mode (a group of stations participating in the wireless LAN). Create or Modify a Configuration Profile To add a new configuration profile, click New on the Profile Management tab. To modify a configuration profile, select the configuration from the Profile list and click the Modify button. The Profile Management dialog box displays the General tab . Profile Management: • Edit the General tab. • Edit the Security tab. • Edit the Advanced tab. To configure a profile for ad hoc or access point (infrastructure) mode, edit the Network Type field on the Advanced tab . Remove a Configuration Profile 1. Go to the Profile Management tab. 2. Select the profile to remove from the list of configuration profiles. 3. Click the Remove button. PRELIMINARY Atheros Communications, Inc. Page 4 COMPANY CONFIDENTIAL February 2005 Auto Profile Selection Management Including a profile in the auto selection feature allows the wireless adapter to automatically select that profile from the list of profiles and use it to connect to the network. Including a profile in auto profile selection: 1. On the Profile Management tab, click the Order Profiles button. 2. The Auto Profile Selection Management window appears, with a list of all created profiles in the Available Profiles box. 3. Highlight the profiles to add to auto profile selection, then click Add. The profiles appear in the Auto Selected Profiles box. Ordering the auto selected profiles: 1. Highlight a profile in the Auto Selected Profiles box. 2. Click Move Up or Move Down as appropriate. The first profile in the Auto Selected Profiles box has highest priority, and the last profile has lowest priority. 3. Click OK. 4. Check the Auto Select Profiles box. 5. Save the modified configuration file. When auto profile selection is enabled by checking Auto Select Profiles on the Profile Management tab, the client adapter scans for an available network. The profile with the highest priority and the same SSID as one of the found networks is the one that is used to connect to the network. If the connection fails, the client adapter tries the next highest priority profile that matches the SSID, and so on. With auto profile selection enabled, the wireless adapter scans for available networks. The highest priority profile with the same SSID as a found network is used to connect to the network. On a failed connection, the client adapter tries with the next highest priority profile. Switching to a different configuration profile 1. To switch to a different profile, go to the Profile Management tab. 2. Click on the profile name in the Profile List. 3. Click the Activate button. The Profile List provides icons that specify the operational state for that profile. The list also provides icons that specify the signal strength for that profile. See also Scan Available Networks. PRELIMINARY Atheros Communications, Inc. Page 5 COMPANY CONFIDENTIAL February 2005 Import and Export Profiles Importing a Profile 1. From the Profile Management tab, click the Import button. The Import Profile window appears. 2. Browse to the directory where the profile is located. 3. Highlight the profile name. 4. Click Open. The imported profile appears in the profiles list. Exporting a Profile 1. From the Profile Management tab, highlight the profile to export. 2. Click the Export button. The Export Profile window appears. 3. Browse to the directory to export the profile to. 4. Click Save. The profile is exported to the specified location. TCP/IP Configuration Configuring the TCP/IP Address for the network device: 1. After configuring the wireless network adapter properties, open the Control Panel and open Network and Dial-up Connections. 2. Find the Local Area Connection associated with the wireless network adapter. Right-click that connection, and click Properties. 3. Select Internet Protocol (TCP/IP) and click Properties. 4. Click the radio button Use the following IP address, then enter an IP address and Subnet mask. Assigning an IP address and Subnet mask allows stations to operate in access point mode (infrastructure mode) or in ad hoc mode and to have Internet access. Default gateway and DNS server information is also required. IP configuration information (DHCP to assign the IP addr…

CALCULATIONS Given E = √ (30 * P * G) / d and S = E ^ 2 / 3770 where E = Field Strength in Volts/meter P = Power in Watts G = Numeric antenna gain d = Distance in meters S = Power Density in milliwatts/square centimeter Combining equations and rearranging the terms to express the distance as a function of the remaining variables yields: d = √ ((30 * P * G) / (3770 * S)) Changing to units of Power to mW and Distance to cm, using: P (mW) = P (W) / 1000 and d (cm) =100 * d (m) yields d = 100 * √ ((30 * (P / 1000) * G) / (3770 * S)) d = 0.282 * √ (P * G / S) where d = distance in cm P = Power in mW G = Numeric antenna gain S = Power Density in mW/cm^2 Substituting the logarithmic form of power and gain using: P (mW) = 10 ^ (P (dBm) / 10) and G (numeric) = 10 ^ (G (dBi) / 10) yields d = 0.282 * 10 ^ ((P + G) / 20) / √ S Equation (1) where d = MPE distance in cm P = Power in dBm G = Antenna Gain in dBi S = Power Density Limit in mW/cm^2 Equation (1) and the measured peak power is used to calculate the MPE distance.
