When performing site surveys, directional antennas minimize the guessing associated with determining where
interferers are transmitting from. Instead of going into each room to see if amplitude increases or decreases,
Wi-Spy users with a Device Finder directional antenna can rotate it to find higher amplitude levels and walk in
the direction until the transmitter is located.
Users can highlight frequency ranges of a
transmitter’s peak signal and track it using a
directional antenna.
This feature only works in live captures, and is very
useful because it gives exact amplitude levels over
time – freeing the user from interpreting color ranges.
Highlight a transmitter by clicking and dragging across
the Density View. Select Device Finder.
A new tab appears with an amplitude over time graph
to track down interfering transmitters.
With Device Finder, users can track down any device,
no matter if the software identifies the interfering
device or not.
This method is perfect for transmitters that emit a
constant signal, like cordless phones or AV
transmitters.
While using the Device Finder graph, continually
monitor the Density View to identify the pattern of the
device.
