TLDR
In this paper, a relay extension system is provided to minimize the investment costs when adding a new service to a new frequency band by using a twisted pair cable and a coaxial cable.
Abstract: 
PURPOSE: A relay extension system is provided to minimize the investment costs when adding a new service to a new frequency band. CONSTITUTION: A remote distribution unit(40) converts a twisted pair signal of a fixed band into an RF(Radio Frequency) signal. The remote distribution unit relays the RF signal through an antenna. At least one additional remote distribution unit(46) is connected to the remote distribution unit by the twisted pair cable and a coaxial cable. The additional remote distribution unit is transmitted to the twisted pair signal of the added band through the twisted pair cable. The additional remote distribution unit changes the twisted pair signal of the transmitted additional band into the RF signal. The additional remote distribution unit transmits the RF signal through to the remote distribution unit to the coaxial cable.

Method and apparatus for coupling an antenna to a device

Paul Shala Henry, +5 more
TL;DR: In this paper, the authors describe a system that receives, by a feed point of a dielectric antenna, electromagnetic waves from a core coupled to the feed point without an electrical return path, and radiates a wireless signal responsive to the electromagnetic waves being received at the aperture.

Backhaul link for distributed antenna system

Paul Shala Henry, +5 more
TL;DR: In this paper, a distributed antenna and backhaul system provide network connectivity for a small cell deployment using high-bandwidth, millimeter-wave communications and existing power line infrastructure, rather than building new structures, and installing additional fiber and cable.
