That, according to Hartley's law, the digital data rate limit, or channel capacity, a physical communication

This definition of bandwidth is in contrast to the field of http://en.wikipedia.org/wiki/Signal_processing, http://en.wikipedia.org/wiki/Wireless_communications, http://en.wikipedia.org/wiki/Modem http://en.wikipedia.org/wiki/Data_transmission, http://en.wikipedia.org/wiki/Digital_communications, and http://en.wikipedia.org/wiki/Electronics, in which bandwidth is used to refer to analog http://en.wikipedia.org/wiki/Signal_bandwidth measured in http://en.wikipedia.org/wiki/Hertz, meaning the frequency range between lowest and highest attainable frequency while meeting a well-defined impairment level in signal power. The connection to the computing term is that, according to http://en.wikipedia.org/wiki/Hartley%27s_law, the digital data rate limit, or http://en.wikipedia.org/wiki/Channel_capacity, of a physical communication link is proportional to its bandwidth in hertz.

I'd like to know what role "of" plays in my example.
Thank you in advance for your help.

It's the preposition for a prepositional phrase of attribution modifying "data rate limit." It tells which limit you're talking about, namely the one associated with a physical communication link.
