Isolating wifi signal

Other Hardware General Electronics
1

Good morning,

I'm looking to isolate the wifi signal, so I imagine I have to turn to a low and high pass filter? I found this site that helps me calculate what I would need RC, RL, LC Passive Filter Calculator | DigiKey Electronics and I ask myself the question: should we take into account the very resistance of the breadboard for example? Because the resistance value necessary to isolate approximately 5ghz is very close to the resistance value of a cable for example so I imagine for the breabord too?

Thank you for your help!

Selective filters at such high frequencies can't be constructed on a breadboard, but can on a very carefully designed PCB.

Advanced skills and calculations taking into account the resistance, capacitance and inductance of all the components, leads and traces are required just to get started, then testing with a full array of lab equipment is usually needed to optimize the result.

Or, just buy professionally designed and manufactured filters: Qualcomm RFFE Wi-Fi Solutions | Qualcomm

If you explain what you actually want to do, forum members might suggest easier approaches.

Thanks,
i want to do a wifi intensity calculator to check my dayly exposition... Just to try it

The RSSI (received signal strength indicator) can be read out of many receivers.

Thanks,

yes just noticed it was possible with any smartphone for example. By bad
