Timer Settings section. The available settings are described in Table 140:
Setting Default Description
Legacy Laptop
Min/Max (sec)
90/360
This timer determines how often to calculate the location for legacy laptop devices.
Taken with the data samples the calculation acts as follows:
l After the minimum timer (default is 90 seconds), check to see if the number of
data samples received from all APs that hear this client are greater than or
equal to the number of samples setting for legacy laptop devices (default of 3
data samples).
l If so (Yes to question above), then recalculate the client device's location based
on the samples received.
l If not (No to the question above), then wait until the number of sample setting is
met before recalculating. If the number of samples is never met, wait until the
maximum timer (default is 360 seconds) and then recalculate.

Laptop Min/Max (sec) 90/360
This timer determines how often to calculate the location for laptop (non-legacy)
devices. Taken with the data samples the calculation acts as follows:
l After the minimum timer (default is 90 seconds), check to see if the number of
data samples received from all APs that hear this client are greater than or
equal to the number of samples setting for legacy laptop devices (default of 3
data samples).
l If so (Yes to question above), then recalculate the client device's location based
on the samples received.
l If not (No to the question above), then wait until the number of sample setting is
met before recalculating. If the number of samples is never met, wait until the
maximum timer (default is 360 seconds) and then recalculate.
Laptop Number of
Samples
3 See definition above.
Phone Min/Max (sec) 60/240
This timer determines how often to calculate the location of phones. Taken with the
data samples the calculation acts as follows:
l After the minimum timer (default is 60 seconds), check to see if the number of
data samples received from all APs that hear this client are greater than or
equal to the number of samples setting for legacy laptop devices (default of 3
data samples).
l If so (Yes to question above), then recalculate the client device's location based
on the samples received.
l If not (No to the question above), then wait until the number of sample setting is
met before recalculating. If the number of samples is never met, wait until the
maximum timer (default is 240 seconds) and then recalculate.
Phone Number of
Samples
3 See definition above.
RFID Min/Max (sec) 30/120
This timer determines how often to calculate the location of RFIDs (such as devices
with tag readers for tracking). Taken with the data samples the calculation acts as
follows:
l After the minimum timer (default is 30 seconds), check to see if the number of
data samples received from all APs that hear this client are greater than or
equal to the number of samples setting for legacy laptop devices (default of 4
