Backhaul link for distributed antenna system
First Claim
1. A system, comprising:
- a first dielectric coupler;
a second dielectric coupler;
an antenna;
a memory to store instructions; and
a processor, communicatively coupled to the memory, to facilitate execution of the instructions to perform operations, comprising;
receiving, by the antenna, a first wireless signal that is converted to a first guided electromagnetic wave that propagates along a first transmission medium, wherein the first wireless signal is generated by a first communication device, wherein the first wireless signal conveys data;
receiving, by the first dielectric coupler, the first guided electromagnetic wave guided by the first transmission medium;
converting the first guided electromagnetic wave to an electronic signal; and
converting the electronic signal to a second guided electromagnetic wave, the second guided electromagnetic wave generated on a surface of a second transmission medium utilizing the second dielectric coupler, wherein the second guided electromagnetic wave conveys the data, and wherein the second guided electromagnetic wave is directed to another system that converts the second guided electromagnetic wave to a second wireless signal conveying the data, and wherein the second wireless signal is directed to a second communication device.

Abstract
A distributed antenna and backhaul system provide network connectivity for a small cell deployment. Rather than building new structures, and installing additional fiber and cable, embodiments described herein disclose using high-bandwidth, millimeter-wave communications and existing power line infrastructure. Above ground backhaul connections via power lines and line-of-sight millimeter-wave band signals as well as underground backhaul connections via buried electrical conduits can provide connectivity to the distributed base stations. An overhead millimeter-wave system can also be used to provide backhaul connectivity. Modules can be placed onto existing infrastructure, such as streetlights and utility poles, and the modules can contain base stations and antennas to transmit the millimeter-waves to and from other modules.
