Initial exercise for path loss

[mayurdhepe]

transmitter: omni directional
Aim receiver antenna
Receiver will have a choice
Note the received signal power.

Notes:
Path loss (dB) = Received signal power = transmitted signal power + transmitting antenna gain in direction of receiver + receiving antenna gain in direction of transmitter + path loss

To calculate antenna gain from pattern

antenna gain at the angle of interest (Volts per Volt)

Convert antenna gain to dB = 20 * Math.log10(antenna gain at the angle of interest)

power level in dBm (power relative to 1 mW) =10*log10(Power level to be converted / 1mW)

Power level in dBW (power relative to 1 W) = 10*log10(Power level to be converted / 1W)
