Figure 59. Roaming Test Connection Range
NOTE: When the
tester roams to a new AP, the
Connection Range line graph shows a green vertical line
at the time the tool connected to the new AP.
PHY Date Rate: The connection's transmit physical data rate
in Mbps.
NOTE: If the tester roams to a new AP after a connection
test has completed, a data rate of -- displays. The dashes
indicate that AirCheck G2 is not currently transmitting
Wi-Fi data and a data rate cannot be obtained.
Signal Level: The connection's signal level in dBm.
Noise Level: The noise level in dBm on the channel used.
SNR: The connection's signal-to-noise ratio in dB.
Retry Rate: The percentage of transmitted frames that are
Wi-Fi retry frames.
Press the Stop button to stop the test.
Press the Log button to see detailed connection activities.
The Access Point Range Test
A range test is used to determine the effective connectivity
range of a specific AP. The connection range shows the
probability of the best possible connection to the access
point from your location.
The best possible connection gives a ping response rate of
100% and the maximum possible data rate. The connection
range value decreases as you move farther away from the
access point. First, the data rate decreases. As you continue
to move away from the access point, the ping response rate
decreases and the connection becomes unreliable.
How to: Start a Range Test
Once AirCheck G2 has connected to an AP, the Tests button
appears at the bottom of the Connect to AP screen (Figure
49).
1 Tap the Tests button to open the Test Type screen.
2 Select Range Test, which presents you with the Select
Target screen.
3 Select a test target.
4 Tap Apply. This opens the Range Test screen and live
data starts to populate the screen.
