I understand that different frequencies are like different pipelines. For instance on 587 MHz u can transmit data on but on 850 MHz u can also transmit data not related to one another. Does anyone understand how this works. And what is the highest frequency we are able to utilize?How is data encoded into a specific frequency?
data, analog or digital can be 'modulated' with just about any RF carrier frequency to produce a modulated RF signal that is usually amplified to significantly bump up the transmitting power. What you're referring to is data multiplexing. As far as highest frequency humans are able to utilize....try 300Ghz any higher and we're talking about playing in the light frequency spectrums.
