摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： One aspect related to design of systems and methods for manufacturing products that include technology in skilled areas is configuring a production station for use by an operator without specialized skills. The present invention contemplates an approach to designing a station configurable to perform one or more of incoming inspection, assembly, testing, and branding. A preferred approach includes verifying data associated with units prior to accepting them for incorporation, preventing incorporation of an incorrect unit, and guiding an operator in possible remedial action. This approach includes storing data in a server and making such data substantially instantly accessible to production stations once written in the server. Such data preferably includes software to configure the production station such that the operator need not have specialized skills. A production station designed using this approach is particularly useful in the manufacture of an outdoor unit of a split-mount microwave radio system.

摘要： Systems and methods for combining signals from multiple active wireless receivers are discussed herein. An exemplary system comprises a first downconverter, a phase comparator, a phase adjuster, and a second downconverter. The first downconverter may be configured to downconvert a received signal from a first antenna to an intermediate frequency to create an intermediate frequency signal. The phase comparator may be configured to mix the received signal and a downconverted signal to create a mixed signal, compare a phase of the mixed signal to a predetermined phase, and generate a phase control signal based on the comparison, the downconverted signal being associated with the received signal from the first antenna. The phase adjuster may be configured to alter the phase of the intermediate frequency signal based on the phase control signal. The second downconverter may be configured to downconvert the phase-shifted intermediate frequency signal to create an output signal.

摘要： An exemplary system comprises a linearizer module, a first upconverter module, a power amplifier module, a signal sampler module, and a downconverter module. The linearizer module may be configured to receive a first intermediate frequency signal and to adjust the first intermediate frequency signal based on a reference signal and a signal based on a second intermediate frequency signal. The first upconverter module may be configured to receive and up-convert a signal based on the adjusted first intermediate frequency signal to a radio frequency signal. The power amplifier module may be configured to receive and amplify a power of a signal based on the radio frequency signal. The signal sampler module may be configured to sample a signal based on the amplified radio frequency signal. The downconverter module may be configured to receive and down-convert a signal based on the sampled radio frequency signal to the second intermediate frequency signal.
