I am very new to this so I apologize in advance if this is a redundant question. I didn't see anything similar in my searches.
Is it possible to have a single radio (2.4Ghz or 5Ghz) with multiple antennas (up to 5) and be able to determine the strength of the signal from the various antennas. For example if you have 5 antennas placed in different locations but attached to the same radio and then determine the exact strength each antenna registers when picking up the same signal.
If this is possible, can anyone give me some suggestions of what radio module(s) I might try for this project?
Any feedback is greatly appreciated.
Thank you,
Adam
No.
Best you could do would be to build a PIN diode RF multiplexor to connect each antenna one at a time to
the receivers input and try and measure the input, but this is not a beginners project.
Also, while some receivers do have a RSSI output, most are not in any way calibrated, so you would need a
calibrated signal generator to calibrate the receiver.
Why measure?
Use Wireless chipsets support MIMO(multiple-input and multiple-output) and leave all the antennas attached same time.
