Using modulation-transcendent rf sampled digital data over an ip connection

The apparatus and methodologies used herein leverages roip to generically transport either conventional modulation (e.g., am, fm, phase or pulse) or complex modulation (e.g., gmsk, cdma, tdma, ofdm, etc.) in real time or near real time across an internet protocol link, such as gigabit ethernet (gbe). The purpose of the invention is a method of creating a live, virtual, modulation transcendent link by using an internet protocol (ip) link to extend the natural range of a connection between an rf signal source (e.g.
