Abstract (en)

[origin: WO2017214162A1] 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. An overhead millimeter-wave system can 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. Uplink and downlink signals (i.e., signals directed to/from a base station from/to acommunication node) can be spectrally divided into control channels, uplink/downlink spectral segments each including modulated signals which can be frequency converted to their original/native frequency band for enabling the communication nodes to communicate with one or more mobile or stationary devices, and pilot signals which can be supplied with some or all of the spectral segments for mitigating distortion created between the communication nodes.The pilot signals can be processed by transceivers of up- and downstream communication nodes to remove distortion from a receive signal (e.g., phase distortion).
