Abstract: An interference detection system comprises memory storing computer instructions to cause a processor to perform gathering a temporal snapshot of radio parameter values associated with a first site of a point-to-point radio system, the radio parameter values including at least a receive signal level (RSL) value and at least one other radio parameter value correlated with signal degradation; determining whether the RSL value is greater than an RSL threshold; determining whether the other radio parameter value indicates a threshold level of signal degradation; when the RSL is greater than the RSL threshold and the other parameter indicates a threshold level of signal degradation during the temporal snapshot, determining that external interference is present during the temporal snapshot; when the RSL is not greater than the RSL threshold, determining that the external interference is not present; and performing a responsive action to a determination of the external interference being likely present.

Abstract: An example method comprises receiving, by a first PHY of a first transceiver, a timing packet, timestamping, by the first transceiver, the timing packet and providing the timing packet to a first intermediate node, determining a first offset between the first intermediate node and the first transceiver, updating a first field within the timing packet with the first offset between the first intermediate node and the first transceiver, the offset being in the direction of the second transceiver, receiving the timing packet by a second transceiver, the timing packet including the first field, information within the first field being at least based on the first offset, determining a second offset between the second transceiver and an intermediate node that provided the timing packet to the second transceiver and correcting a time of the second transceiver based on the information within the first field and the second offset.

Abstract: An example system comprises a router configured to receive a bandwidth update associated with a change in bandwidth over a wireless channel, determine if the change in bandwidth identified in the bandwidth update results in bandwidth being over-reserved at at least one priority level, previously reserved bandwidth of the wireless channel being associated with a plurality of different priority levels, the previously reserved bandwidth being previously reserved based on a plurality of path requests from a head end router, each path request including at least one priority level and a bandwidth reservation request, if the change in bandwidth results in bandwidth being over-reserved, then preempt a lowest priority path request, based in the preemption of the lowest priority path request, update reserved bandwidth of the wireless channel of at least one priority level, and provide a message to the head end router regarding the change of bandwidth.

Abstract: Rapid failure detection and recovery in wireless communication networks is needed in order to meet, among other things, carrier class Ethernet transport channel standards. Thus, resilient wireless packet communications is provided using a hardware-assisted rapid transport channel failure detection algorithm and a Gigabit Ethernet data access card with an engine configured accordingly. In networks with various topologies, this is provided in combination with their existing protocols, such as rapid spanning tree and link aggregation protocols, respectively.
