I explain RSSI and how we can get the mos out of it with the x8r and Taranis
Just a snippett from the Fluke Networks Wireless Workshop Here I review the term RSSI and how to interpret it. Linkedin Profile http://ca.linkedin.com/in/fortunat Lovemytool Blog: http://www.lovemytool.com/blog/tony-fortunato/ Youtube Channel: http://www.youtube.com/user/thetechfirm
I am a big fan of teaching methodology and ask people who attend my presentations, not to focus on my results, but rather understand how I do things so you can reproduce my test. In this example I discuss the merits of understanding how well your access points hear your clients. I chose a popular Samsung Galaxy S2 smartphone and recorded the receive signal strength from the access point’s perspective. When you conduct this type of test, you should be aware that many WiFi devices will change the radio behavior depending on power and if it transmitting any data. To ensure consistency, I simply ‘pinged’ the phone’s IP address every 10 millisecond using hrping. As I said in the video, I’m not expecting you to do this for every device, in every location in every orientation, but think its important to understand this behavior for those tricky WiFi issues. I actually used this methodology when troubleshooting a problem in a warehouse with WiFi terminals mounted in forklifts that were dropping their connection. In the end I found two very important details; 1. The signal strength was marginal at best since the survey was completed using highly sensitive directional antennas and the terminals had less sensitive omnidirectional antenna’s. 2. There was an area of the warehouse with a lot of metal shelving that, in combination with the forklift orientation caused the RF signal to drop and the connection to drop. Enjoy

I understand there are RSSI pads on some receivers, and you can get the RSSI into your OSD that way. But I'll show you a way that requires no extra wiring. It only uses one channel from your receiver. This is also useful if you receivers doesnt even have a RSSI pad. Amazon...................

In this video I'm going to show you my sketch I'm using for my current project. This sketch allows you to get-read the RSSI Signal using a Arduino. For Code and more informations: http://letsmakerobots.com/node/37243 This video shows you how to get the RSSI Value of an Xbee! I use Xbee Series 2 but I think Series 1 works too Sender: AT Mode Receiver: API Mode Sender sends data after 100ms.
