Filter Threshold Constants T1,
T2, and T3
144
where the domain of K is {K: K = K1, K2, K3} and 0 (no filter) <= K3 <=
K2 <= K1 <= 9 (heavily damped filter).
K1 Used when less than 8 seconds elapse between RSSI samples.
K2 Used when between 8 and 16 seconds elapse between RSSI
samples.
K3 Used when more than 16 seconds elapse between RSSI samples.
Use the UP/DOWN arrows to make your selection or enter a value
directly. The threshold constants T1, T2, and T3 create a window that
RSSI samples must fall into in order to be considered valid. The
window is centered around the current RSSI Filter Value. The window
size is twice the value of the threshold constant.
The values (T1, T2, T3) are expressed as hexadecimal numbers ranging
from 0 (zero) to FF and should only be modified in accordance with
the following:
00 <= T1 <= T2 <= T3 <= FF
T1 Used when less than 8 seconds elapse between RSSI samples.
T2 Used when between 8 and 16 seconds elapse between RSSI
samples.
T3 Used when more than 16 seconds elapse between RSSI samples.
Note: Modification of filter threshold constants should be performed
only under the direction of a qualified radio engineer.
