Signals used to test for upstream signal leaks in a hybrid fiber-coaxial (HFC) network may be interleaved with client data and strategically timed to be received by a leak detection device with a one-hundred percent probability of intercept. A method includes receiving an indication that a user device is in proximity to a computing device. The method includes determining, based on the indication that the user device is in proximity to the computing device, signal information. The method includes causing, based on the signal information, the user device to output a signal. The method includes determining, based on an indication that the signal was received by the computing device, a location of a network leak.

Methods and systems for determining signal leaks in a network

Methods and systems for monitoring an optical network are described. An optical device may receive a data signal. The optical device may send the data signal to a test port. A measuring device may measure characteristics associated with the data signal.

Methods and systems for monitoring optical networks

A mesh network may be established between a plurality of access points to facilitate load balancing for one or more of the access points. The mesh network may define a plurality of communication routes through the access points having capabilities sufficient to facilitate or mimic communications underperforming or being unavailable at the access point requesting load balancing.

Mesh networking of access points for load balancing

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.

Hybrid full duplex communications in a radio frequency cable network

Systems and methods herein provide for the aggregation of a plurality of wireless base stations for access by a Mobile Central Office (MCO) communicating with user equipment (UEs) through a network. In one embodiment, a communication system includes a first plurality of wireless base stations, each being operable to communicate with UEs. The system also includes a base station aggregator operable to aggregate the wireless base stations into a virtual base station, and to interface with the MCO. The base station aggregator is further operable to process a request from the MCO for access to communications provided by the virtual base station, to grant the request, to intermediate on behalf of the MCO, and to exchange communications between the MCO and a UE subscribing to the MCO and operating within the coverage of the virtual base station.

Virtual cells for radio access network (RAN) sharing

Systems and methods for performing broadband profile management in a cable network are disclosed. The method may include establishing a network connection with a cable modem termination System (CMTS) and discovering OFDM channels utilized by the cable network where each of the OFDM channels includes a plurality of OFDM subcarriers. In addition, a current set of profiles for the cable network is discovered and each of the profiles defines a modulation order for each of the plurality of OFDM subcarriers in each OFDM channel. Signal quality values are obtained for the plurality of OFDM subcarriers to generate a mapping between the signal quality values and the OFDM subcarriers, and a plurality of profiles are generated based upon the mapping between the signal quality values and the OFDM subcarriers. Then each of the cable modems is assigned to one of the plurality of profiles.
