## Using the Intel® PRO/Wireless LAN Site Survey Utility

Use the Site Survey Utility to establish a two-way data network using both stationary and mobile devices at various points within the proposed radio coverage area.

## Starting the Site Survey Utility

To start the Site Survey Utility, click Start, Programs, Intel® Wireless LAN, Access Point Administration Utilities, and then Site Survey. Another way to start the Utility is to double-click the Site Survey icon on the Windows* desktop.

When you are running the software, use the F1 key or Help button for additional information.

A dialog box displays prompting you to choose the type of wireless LAN card installed in your computer, then the Site Survey Utility Welcome dialog box displays.

Use the Welcome dialog box to

- Open an existing site survey area workspace.
- Create a new workspace.
- Create a new workspace from an existing site survey area workspace ( .ssw ) or site survey template ( .sst ) file.
- Open a recently used workspace.

A workspace corresponds to the entire survey site area. An area contains one or more radio coverage areas within a survey site. Create a separate workspace for every survey conducted at the same site. After you select one of the options and click OK, the Site Survey dialog box displays.

### Creating a New Site Survey

To create a new site survey, select New Site Survey from the File menu. Select the date and type in the site name, the surveyor, and a description.

### Selecting an Existing Site Survey

To open a standard Windows dialog box displaying site survey workspace (.ssw) files, select Open Site Survey from the File menu.

- If an invalid file is read, an error message displays. Otherwise, a bar graph displays the progress as the workspace is loaded.
- If the workspace has at least one defined area, the Site Survey Test dialog box opens.
- If the existing workspace does not have a defined area, the Site Survey Area dialog box opens.

The status bar displays the workspace and area name.

### Defining a New Site Survey Area

To define a new site survey area, display a Site Survey Area dialog box. To display this dialog box, select New Area from the File menu.

- Type the area name and a description.
- An error message displays if you leave the Area Name field blank or enter the name of an existing area. The area name displays at the bottom of the screen.
- The Test Name field lists the tests defined for that area. To add a new test, click the ellipsis ( ...) button.

| NOTE: Delete is disabled when defining a survey area.

### Saving a Workspace

- To save the open workspace using the existing survey name, select Save from the File menu.
- To save the survey using a different name, select Save As from the File menu.

### Importing a Site Survey

To import a site survey, select Import from the File menu. The Import Areas and Tests dialog box displays.

- To replace existing survey areas and tests or to add new ones, select Import Areas or Import Tests or both, as appropriate.
- To open a standard Microsoft Windows dialog box displaying site survey workspace (.ssw) files, click Import.

### Working with Reports

You can generate, edit, and print a Site Survey Report for each site survey workspace. The Site Survey Report is a Microsoft WordPad document generated when the survey is complete.

The report can be edited as a typical WordPad Rich Text Format (RTF) document. The template for a new report has the filename "Site Survey Results.doc" and is installed in the same directory as the Site Survey Utility program.

#### Displaying Recent Site Surveys

To display the last four site survey workspace files created or accessed, select Recent Site Surveys from the File menu.

Select any workspace in the list to load that workspace.

- If a workspace is already open, you are prompted to save the existing workspace first.
- If there is at least one Area defined for the workspace, the Site Survey Test dialog box opens.

The status bar at the bottom of the dialog box displays the status, filename, area name, and workspace name.

### Editing Existing Site Survey Information

To edit existing site survey information, select Site Survey from the Edit menu. The Site Survey dialog box displays. Enter the site name, surveyor, and a description.

If a workspace is already open, you are prompted to save the existing workspace. To save the edited workspace information, click OK.

### Editing the Properties of an Existing Site Survey Area

To view a list of existing site survey areas, select Area from the Edit menu. The Site Survey Area List dialog displays.

Browse the list and descriptions of the survey areas. To edit the properties of an existing site survey area, select an area name and click Edit Area.

Run the Site Survey Utility in either automatic or manual mode. To run the test suite for the rerun count or until the surveyor stops the tests, check Auto Rerun.

##### ICMP Host Address

Type an ICMP Host Address in the field provided. The default address is the default address of the access point.

##### Ping Count

Type in the number of pings to be transmitted during the ping test in the Ping Count field. The default Ping Count is 100 , with a maximum of 2000.

##### Rerun Count

Enter the number of times the ping test is transmitted in the Rerun Count field. The default Rerun Count is 100 . The rerun can be 1 to 2000.

Use the Noise Meter dialog box to view the mobile computer BSSID and the RSSI minimum, maximum and average values. The RSSI values displayed in the graph continuously update with the last six received values displayed in blue.

- In a 2.4 GHz environment a graph displays the average signal level ranging from 0 to 31. See the dialog box below. It is calculated as the mean of the maximum and minimum signal values over time.

To start calculating statistics again,
