Hello, my thesis is based on providing mobility to a Lifi user in a room using LED transmitters. I will be adjusting the distance between LEDs to give a continuous pattern in a specific room so there's no void space left between the signal lobes. For that I need to physically move the detector under a transmitting LED to check 'Signal Strength'. The photodetector (receiver) is connected with Channel 1 of the oscilloscope, what do I measure to determine signal strength including point of disconnection, using oscilloscope?
Hint: I have measure dc levels and form a tabular data!
