This seems like a misunderstanding of the technologies. Mobile networks modulate RF and emit it via antennas, cable networks modulate RF and carry it via RF cables (aka coaxial cable, or "cable"). Its the same technology from a fundamental standpoint, but the latter has superior propagation characteristics and dramatically reduced noise. Wireless can't be better than wired - if it was, you'd just connect the LTE or whatever transceivers to the cable plant and be done with it.
