Abstract: Systems and methods presented herein provide for an LTE wireless communication system operating in a Radio Frequency (RF) band with a conflicting wireless system. The LTE system includes an eNodeB operable to detect a plurality of UEs in the RF band, to generate LTE frames for downlink communications to the UEs, and to time-divide each LTE frame into a plurality of subframes. The eNodeB is also operable to condense the downlink communications into a first number of the subframes that frees data from a remaining number of the subframes in each LTE frame, and to burst-transmit the first number of the subframes of each LTE frame in the RF band.

Abstract: A method for transmitting data in a communication network including a shared communication medium includes (a) transmitting local data between a first client node and a second client node according to a first data protocol, using a first shared communication medium, and (b) transmitting remote data between the first client node and a network hub according to a second data protocol different from the first data protocol, using at least the first shared communication medium.

Abstract: Facilitating echo cancellation within communication networks is contemplated, such as but not necessarily limited to facilitating echo cancellation within full-duplex (FDX) communication networks. The echo cancellation may optionally be performed with an echo canceller included as part of or otherwise associated with an FDX node used to facilitate interfacing signaling between a digital domain and an analog domain of a FDX or other communication network.

Abstract: A method for virtually performing delta-sigma digitization is provided. The method is performed on a series of digital samples output from a communication stack of a communication network. The method includes steps of obtaining a delta-sigma digitization sampling frequency for the output series of digital samples, calculating an oversampling ratio for the output series of digital samples, interpolating the output series of digital samples at a rate equivalent to the oversampling ratio, and quantizing the interpolated series of digital samples to plurality of discrete predetermined levels.

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.
