Abstract

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. transmitter) and an RF receiving device (e.g. receiver). This methodology is referred to herein as radio frequency over internet protocol (RFoIP).

Claims (16)

1. Apparatus for real-time data streaming using modulation-transcendent RF sampled digital data over an IP connection, said apparatus comprising:

a first transmission station, said first transmission station comprising:

a transceiver;

an RF digitizer, said transceiver configured to transmit to said RF digitizer, and said RF digitizer configured to digitize the transmission by said transceiver;

a low voltage differential signaling/gigabit Ethernet (LVDS/GBE) converter, said LVDS/GBE converter configured to receive the digitized transmission from said RF digitizer, and to communicate the digitized transmission over the internet;

a second transmission station, said second transmission station comprising:

GBE/LVDS converter, said GBE/LVDS converter configured to receive the digitized transmission from the internet;

a transceiver;

an RF signal generator, said RF signal generator configured to receive the digitized transmission from said GBE/LVDS converter and to convert the digitized transmission to a signal, and said RF signal generator further configured to transmit the signal to said second transceiver;

an RF digitizer, said transceiver of said second transmission station configured to transmit to said RF digitizer therein, and said RF digitizer of said second transmission station configured to digitize the transmission; and

a LVDS/GBE converter, said LVDS/GBE converter of said second transmission station configured to receive the digitized transmission from said RF digitizer therein, and to communicate the digitized transmission over the internet;

and

wherein said first transmission station further comprises:

a GBE/LVDS converter, said GBE/LVDS converter of said first transmission station configured to receive the digitized transmission from the internet; and

an RF signal generator, said RF signal generator of said first transmission station configured to receive the digitized transmission from said GBE/LVDS converter therein and to convert the digitized transmission to a signal, and said RF signal generator of said first transmission station configured to transmit said signal to said first transceiver therein.

2. The apparatus according to claim 1 , wherein each said GBE/LVDS converter is configured to provide resolution in the range of 8 bits to 14 bits.
