1.4.7 Checking cellular modem signal strength
To check the signal strength of a 3100-iSIC cellular modem you can use a program called
Wireless Ace. This utility is available from the support section of the Airlink Communications
website: www.airlink.com or on the 3100-iSIC Companion CD:
http://www.nexsens.com/support/downloads.htm
After installing Wireless Ace on your computer, run the program and click the Connect button.
Enter the IP address of the modem and click OK.
Wireless ACE will connect to the modem. If successful it will show the modem information in the
main part of the screen. Click on the word “Status” and then look at the RSSI Value. The
optimal range for 3100-iSIC cellular modems is -60 to -95. Low RSSI will affect the functionality
of the unit and the ability to communicate to it. If you are experiencing too low of RSSI you may
want to try moving the data logger to another location, or raising the cellular antenna with a
longer RF cable.
