Introduction to the Laird Connection Manager

Laird Technologies delivers a connection management and monitoring utility called the Laird Connection Manager (LCM), the successor to the Summit Client Utility (SCU). LCM allows you to view all radio and security settings, and status. It also enables you to troubleshoot connectivity issues.

The following is a detailed list of what you can view using the LCM:

  • Individual Laird Wi-Fi radio configuration profile contents including radio and security settings.
  • Global settings, which apply to every profile.
  • A snapshot status of the current wireless network connection.
  • Detailed status information on the radio, the access point to which it is connected, and the RF connection on link between the two.
  • In-depth diagnostic information on the radio and its connection, so users can accurately report key data to an administrator when there is a connection or performance issue.
  • Other radio information, such as software versions and regulatory domains.

Note: LCM management functions are only available to administrators. For more information on administrator functions, refer to the Laird Administrator's Guide which can be accessed from the Laird Wi-Fi Documentation page.

This LCM User's Guide provides the following information:

  • Instructions on how to access LCM.
  • Detailed information regarding LCM windows including Status, Configuration, and Diagnostics.
  • Brief information on Wi-Fi profiles and global settings.
  • Brief information on Bluetooth devices and settings.
  • Instructions on how to use the Laird System Tray Icon (only available for Windows CE and Windows Mobile).


Accessing the Laird Connection Manager

This version of the LCM is available for Windows Embedded CE and Windows Mobile. To access LCM from the Start menu, select Programs > Laird > Laird Connection Manager.

The Laird directory includes the LCM application and a directory for the storage of security certificates.

To run LCM, double click the LCM icon. The LCM has three tabbed windows:

To view a window, tap the applicable tab.



Status Tab

LCM_status_image  

Figure 1: Status tab   

The status tab is divided into Wi-Fi and Bluetooth sections. The Wi-Fi section provides status information on the radio's Wi-Fi connection between the client device and the access point to which it's associated. The Bluetooth section provides status information on the radio's Bluetooth connection between the client device and the destination device.

The Status tab displays the following sections:


The two images at right (Figure 1) are the LCM Main windows for Windows CE/Windows Mobile and Windows XP operating systems.

Status - Wi-Fi

The Wi-Fi section of the Status tab provides the following information:

Status 

Indicates the current status of the Laird Wi-Fi radio. Connection statuses include:

 

Down: The radio is not recognized by Laird software and therefore is not associated or authenticated.

 

Disabled: The radio is disabled. To enable the radio, check the Wi-Fi check box located on the Configuration window. When the radio is disabled, it does not attempt to make a connection to an access point.

 

Not Associated: The radio has not established a connection to an access point.

 

Associated: The radio has established a connection to an access point but is not EAP authenticated. The radio cannot communicate unless it is associated and EAP authenticated. 

Note: If the Encryption type is set to WEP or Open (None), it can communicate (send data) while in the Associated state.

 

Connected to [SSID]: The radio is connected to the named SSID.

IP Address 

Displays the IP address of the Wi-Fi device.

Signal Strength 

Displays the signal strength (or RSSI) in dBm.


Status - Bluetooth

The Bluetooth section of the Status tab provides the following information:

Status 

Indicates the current status of the Laird Bluetooth radio. Connection statuses include:

 

Down: The radio is not recognized by Laird software and therefore is not associated or authenticated.

 

Disabled: The radio is disabled. To enable the radio, check the Bluetooth check box located on the Configuration window. When the radio is disabled, it does not attempt to make a connection to an access point.

 

Not Connected: The radio is not connected to any Bluetooth devices.

 

Paired, Not Connected: The radio has found a Bluetooth device but is not paired with it.

 

Connected: The radio is connected to a Bluetooth device.

MAC 

The local device's MAC address.

Signal Strength 

Displays the signal strength.


Note: Although you can view current settings, you cannot make any changes to LCM from the Status window.



Configuration Tab

Using the Laird System Tray Icon

On Windows CE or Windows Mobile, Laird software includes a service that displays an icon in the Windows System Tray. This icon provides a visual status for the Laird Wi-Fi radio in the device and it provides access to the LCM application. The image at right (Figure 4) shows the Laird System Tray Icon.

Note: Tap the icon to launch the LCM application.

The service is active and displays an icon in the System Tray only when all of the following conditions are met:

  • A Laird Wi-Fi radio is installed in the device or inserted in an external slot in the device.
  • The device is active.
  • Windows Zero Config (WZC) is not active.
  • The LCM Tray Icon global setting is On (the default setting).

When the service is active, it queries the radio every three seconds for connection status. Based on the radio's response to the query, the service displays one of the following icons:

Table 4: LCM Tray Icons 

RSSI0  The radio is not associated/authenticated to an AP.
RSSI1  The signal strength (RSSI) for the current AP (to which the radio is associated) is -90 dBm or weaker, which means that a Laird 802.11b/g radio will operate at 802.11b data rates only.
RSSI2  The RSSI for the current AP is stronger than -90 dBm but not stronger than -70 dBm, which means that a Laird radio will operate at 802.11g or 802.11a data rates that are less than 54 Mbps
RSSI3  The RSSI for the current AP is stronger than -70 dBm but not stronger than -50 dBm, which means that a Laird radio should operate consistently at 54 Mbps
RSSI4  The RSSI for the current AP is stronger than -50 dBm.

LCM Bluetooth Tray Icon 

The Bluetooth tray icon displays connectivity and power status for the Bluetooth radio.  It displays one of the following:

BT0  The Bluetooth radio is disabled, and therefore disconnected.
BT1  The Bluetooth radio is enabled, but is not connected.  
BT2  The Bluetooth radio is connected to a device.


Tapping the icon launches the LCM.  On most CE devices, the System Tray icon is not visible while LCM is running, although the service remains active.

 Note: If LCM usually runs on the device, or if you want to maximize performance, then you should disable the System Tray icon service by setting the Tray Icon global setting to Off and power cycling the device.
