5g over coaxial node systems and methods

A node apparatus comprising:

• a Distributed Unit (DU);
• and
• a Radio Unit (RU) in communication with the DU, wherein the RU comprises:
• a first port for interfacing with a signal transmitted from the DU, wherein the signal transmitted from the DU comprises at least an 8 layer spatial stream;
• a Digital Front End (DFE) configured to process the spatial stream by combining a first four streams of the spatial stream in a first Digital to Analog (DAC) converter to form a first signal, and by combining a second four streams of the spatial stream in a second DAC, to form a second signal;
• a first Power Amplifier (PA) configured to boost a signal strength of the first signal;
• a second PA configured to boost a signal strength of the second signal;
• a Radio Frequency (RF) combiner configured to combine the first signal and the second signal into a combined signal;
• an impedance matching component configured to sufficiently match the combined signal;
• and
• a second port in communication with a coaxial cable, wherein the coaxial cable is configured to transmit the combined signal.
