Abstract: A tool listening device including a transceiver is configured to listen on a radio channel selected from a discovery channel hopping sequence. The tool listening device is configured to identify a preamble, indicating a start of a packet. The tool listening device continues to listen until a packet header is received. The tool listener extracts, from the packet header, a source address, a destination address and a frame type. The tool listening device adds the source address, the destination address, and the frame type to a data structure, and transmits the data structure to an external device, where the data may be visualized. The tool listening device is further configured to select another radio channel from the discovery channel hopping sequence.

Abstract: A method includes identifying a packet for transmission and determining a radio channel for the transmission of the packet. The method further includes determining that the packet is in a restricted class and, responsive to the packet being in the restricted class, determining a dynamic maximum available time on the radio channel based on a reserved time and a dwell time limit. The method further includes calculating a remaining dwell time on the radio channel based on a comparison of a spent dwell time on the radio channel to the dynamic maximum available time. Further, the method includes determining a transmission duration for transmitting the packet over the radio channel and, responsive to the remaining dwell time being less than the transmission duration, postponing the packet.

Abstract: A single ended, frequency domain reflectometry signal processing based scheme measures loop loss of a telecommunications wireline. A distortion-corrected, normalized data array is differentially combined with an associated set of wireline noise spectrum values. The resulting noise margin data is processed by a Shannon Theorem operator, to produce a set of N frequency bins, each containing the number of bits which the link will support for a respective tone. The bit contents of the bins represent a composite bit rate that is available for use for ADSL signalling.
