Abstract: The present disclosure generally relates to systems, methods and software for quantitatively comparing an overall capacity improvement for a channel used for transmissions to a population of user devices when an existing profile is replaced with a proposed profile. Additionally, the quantitative comparison can be used to prioritize profile changes and/or network maintenance.

Abstract: An ad-hoc wireless network is implemented by a plurality of wireless access points to detect and report failure of a concurrently implemented conventional network. The wireless access points collect and store network status information of the conventional network and send the network status information to a centralized emergency manager when failure of the conventional network is detected. The ad-hoc wireless network may also provide backhaul connectivity to a wireless access point of the failed conventional network for emergency communication.

Abstract: A method for automatically identifying an impairment of a communication medium includes (1) obtaining a spectrum response of communication signals traveling through the communication medium, (2) converting the spectrum response from a frequency domain to a time domain, to generate an impulse response, and (3) identifying the impairment of the communication medium at least partially based on one or more characteristics of the impulse response.

Abstract: A transmitter is configured to transmit data to a receiver over a communications network. The transmitter includes a memory for storing computer-executable instructions and a processor in operable communication with the memory. The processor is configured to (i) collect spectrum data of a spectral band over a first sampling interval, and (ii) store the collected spectrum data in the memory. The transmitter further includes a common path distortion (CPD) detection unit configured to (i) sample the collected spectrum data, over a second sampling interval less than the first sampling interval, for a plurality of sub-bands within the spectral band, (ii) analyze the spectral band and each sub-band for indications of common path distortion, and (iii) inject a test signal configured for detection at a headend of the communications network. The transmitter further includes a modem portion configured to operably communicate with the headend and the receiver.

Abstract: Authenticating a device is contemplated. The authenticating may include generating an authentication sufficient to represent trust in an identity of a device when being provisioned or re-provisioned for network access, reconciling inventory management and/or otherwise performing operations dependent on trust.

Abstract: Grafting segments of a network together to mitigate service disruptions associated with impairments, maintenance, etc., is contemplated. The grafting may include instantiating a wired and/or wireless graft to facilitate connecting an impaired portion of a network to an unimpaired portion, such as to reestablish services at the impaired portion via the graft to the unimpaired portion.
