Hello everyone, Thanks for all the tips. I was thinking getting this antenna: https://www.amazon.com/Super-Power-Supply-Directional-Wireless/dp/B016APUGB6/ref=sr_1_8?s=pc&ie=UTF8&qid=1481113798&sr=1-8&keywords=wifi+directional It's compact and perfect for 2.4 GHz band. Just need to get an RP-SMA to SMA converter adapter to use it with HackRF.
But i am still not sure where to look for interference. Which software i should use and what should i look for? I was thinking running SDRsharp with RX gain settings adjusted (low gain settings to pick any signal from 2.4GHz device when i physically close to it) I have decided to use HackRF after i came across a wifi analyzer device called Chanalyzer http://www.metageek.com/products/wi-spy/ They provide a fancy software to determine possible intereference source and they are quite expensive, around $2000. But i think i won't need any fancy software or look out for any specific waveform determine this interference, right? Again, i have no idea what should i look for. (Noise? Waveform?) Any ideas would be great. Thanks! On Wed, Dec 7, 2016 at 8:21 AM, Scott Davis <[email protected]> wrote: > There are many, many commercial directional antennas available for the 2.4 > GHz band.
