Abstract: A communication system includes an earth station configured to receive a downlink transmission from a satellite and transmit an uplink transmission to the satellite. The communication system further includes a server in operable communication with the earth station, a beacon detector in operable communication with the server, an access point configured to operate within a proximity of the earth station, and a beacon transmitter disposed within close proximity to the access point. The beacon transmitter is configured to transmit a beacon signal to one or more of the server and the beacon detector. The beacon signal uniquely identifies the access point. The server is configured to implement a measurement-based protection scheme with respect to at least one of the downlink transmission and the uplink transmission.

Abstract: Systems and methods presented herein provide for improved duplex communications in an RF cable network comprising a plurality of CMs. In one embodiment, a system includes a CMTS operable to transmit downstream communications to the CMs and to process upstream communications from the CMs. The system also includes a duplex RF communication path between the CMTS and the CMs. The CMTS is further operable to transmit a control signal that directs a first of the CMs to transmit, to direct the remaining CMs to receive the transmission from the first CM, to direct the CMs to report received power levels of the transmission from the first CM, and to calculate RF isolations of the remaining CMs with respect to the first CM based on the reported power levels.

Abstract: Correction of errors within over-the-air signaling is contemplated. The error correction may include correcting over-the-air signaling used to facilitate transmitting content, broadcast television, etc. according to error correction data transmitted separately from the over-the-air signaling. A receiver may be configured to process the over-the-air signaling according to the error correction data so as to facilitate the contemplated error correction.

Abstract: Systems and methods presented herein provide for optimizing or otherwise improving capacity in a communication network. In one embodiment, a method is operable in a network hub that is communicatively coupled to UEs via a plurality of communication links. Each communication link has a different data rate capacity and each UE comprises a profile that indicates its data rate capabilities (e.g., modulation schemes and the like). The method includes detecting communications of the UEs, determining the data rate capabilities of the UEs from their profiles, and determining how many different data rate capacities the network hub supports over the communication links. The method also includes grouping the UEs according to their data rate capabilities, generating a common profile for each UE group, and assigning the communication links to the UE groups based on their common profiles.

Abstract: A method to test a signal path with vacant bandwidth by sending a test signal twice and processing two resulting nonlinear distortion signals captured in the vacant bands to determine presence of nonlinear distortion. If the signals correlate, the energy in the vacant bands is nonlinear distortion. If the test signal is sent followed by an inverse (in time-domain) of itself, and a resulting correlation peak is negative, the nonlinear distortion is determined to have been created by odd-order nonlinear distortion.

Abstract: Signal transport with noise cancellation is contemplated. The noise cancellation may be facilitated with a transmitter configured to induce echoes in a signal desired for transport in order to facilitate subsequently retrieving signal components associated with noise influenced portions of the transported signal from non-noise influence portions of the transported signal.

Abstract: Methods, systems, and devices for network maintenance are described. A controller may receive an indication that the performance of a network device has decreased. The indication may include case identification data associated with the network device. The controller may request proactive network maintenance (PNM) data associated with the network device based on receiving the case identification data. The controller may transmit the PNM data to a machine learning (ML) engine. The ML engine may transmit, to the controller, an indication of a predetermined operation predicted to improve the performance of the network device. The controller may transmit the predetermined operation to a client device based on receiving the indication of the predetermined operation. The ML engine may receive feedback indicating whether an execution of the predetermined operation improved the performance of the network device. The ML engine may a training data set based on the feedback.
