Abstract: A method for operating a wireline communication device on a wireless communication network includes (a) receiving a downlink radio frequency (RF) electrical signal at a first connector, (b) converting the downlink RF electrical signal to a downlink access signal having a format that is compatible with the wireline communication device, and (c) providing the downlink access signal to a second connector for transporting to the wireline communication device. A method for extending a wireline communication network includes (a) receiving a downlink wireline signal at a node of the wireline communication network, (b) converting the downlink wireline signal to a downlink RF electrical signal, and (c) converting the downlink RF electrical signal to a downlink wireless signal, for transmission to one or more communication devices which are not physically connected to the wireline communication network.

Abstract: Systems and methods presented herein provide for altering communications of a LTE wireless communication system operating in an RF band with a conflicting WiFi system. In one embodiment, an LTE system includes a wireless base station operable to transmit downlink communications to a UE in the RF band and to receive uplink communications from the UE in the RF band. The LTE system also includes a processor operable to detect the uplink communications from the UE, to estimate a location of the UE based on the detected uplink communications, to determine a communication capability between the UE and the wireless base station based on the location of the UE, and to downgrade the downlink communications from the wireless base station to the UE based on the determined communication capability to avoid interference with the WiFi communication system.

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: 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: A method for detecting aggressive signal transmission signatures in a wireless communication network is provided. The network includes at least one cooperative device, an access point, and at least one non-cooperative device. The method includes steps of generating a matrix of at least 8 bits configured to register each instance of at least one of a clear-to-send frame and a request-to-send frame transmitted between the at least one cooperative device and the access point during a specified duration, calculating a cumulative distribution function based on the registered instances within the generated matrix for a probability of the presence of an aggressive transmission signal by the at least one non-cooperative device within a measurable vicinity of one or more of the cooperative device and the access point, and determining the presence of the aggressive transmission signal based on the calculated cumulative distribution function being greater than a predetermined threshold.
