(FYI:  The internal antennas are called PIFA Antennas)

After the modification.

No soldering required; just pop them on!

Wi-Fi Radar Scanners

Scanners work with Windows XP, Vista, and Win7 (32 and 64-bit)

When you purchase the Mod Kit don't forget to remind us

and we will send you a link to a FREE download for the two Wi-Fi Radio Scanners.

Wi-Fi Frequency Scope #1

The Wi-Fi Scope continually sweeps the area for internet connections.
Works great for adjusting any external antennas you have attached.
For example, if Blackstone is an open connection we will make adjustments
to our antennas with the objective of getting Blackstone in a range where
we can make a good connection:  -50 to -70 is ideal.  The closer to center the better.
The scope shows we are currently connected to a Linksys/DD-WRT Router at -53. 

Look at the Menu above.
Lots of cool Testing options including a User's Guide,
Speed Test, Quality Test, Connection Test.

Quality Test

Speed Test

Connection Test

An excellent Diagnostic Test to look for Wi-Fi Networking Problems;
much better than Microsoft

Wi-Fi Freqency Scope #2

Wi-Fi Signal Strength

Nice chart for monitoring signal strength from various Internet connections in your neighborhood.

In the graph above we are Transmitting on Channel 6 at 300 Mbps. 

Wi-Fi Radar Scanners are great for laptops too!


Wi-Fi Radar Scanner on campus
Look at all the signals that are being broadcast.  A jumble of activity.
RSSI (Received Signal Strength Indication): The closer to -0 the better the signal, and the closer to -100 the worse.
 Notice two are open for public access but the signal from both is weak: -90.
So we will move about campus with our laptop to see if we can get a stronger signal. 


Thanks for stopping by!
