Fibre optic may well be expected to be quicker - after all the bandwidth there is technically possibly many times that of 'wireless' - because you can only, according to 'Shannon', stuff so much content into a transmission medium depending on the 'native bandwidth' - wireless has a 'frequency' of the possible 'on and off bits' that is orders of magnitude lower than that of visible light due to the relative 'frequencies of the possible on and off bits in a given period of time' - ie the wavelength/frequency.
