3.10.5 ECHO TESTS
This function is used to measure the coverage of the range, estimate the number of APs
and mobile computers needed, and determine the topology of deploying APs.
Client Mode
Set the mobile computer as a client. Enter the IP address of a server with which a connection is
desired. Then, it will try to connect to an AP.
1. Run the utility “EchoTest.exe” on your computer. Associated settings include
- Select “TCP/IP – Server” for interface.
- Set Action Mode to “Passive”.
2. Start the echo test on both ends.
3. Enter the server IP and port number on the mobile computer.
Server Mode
Set the mobile computer as a server. The mobile computer will try to connect to an AP.
1. Run the utility “EchoTest.exe” on your computer. Associated settings include
- Select “TCP/IP – Client” for interface.
- Set Action Mode to “Passive”.
2. Start the echo test on both ends.
While running echo tests, if WPA setting is enabled for security, the SSID and Passphrase
will be processed to generate a pre-share key.
Note: If you change the SSID or Passphrase, it will have to re-generate a pre-share key.
1) For initial association with an access point, you will see an antenna icon developing
on the screen to indicate that the mobile computer is processing a pre-share key.
2) After having generated the pre-share key, the mobile computer proceeds to establish
a connection with an access point, and you will see the whole antenna is flashing.
3) When the mobile computer has been connected to the access point successfully, you
will see the whole antenna and the indication of wireless signal strength.
