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: A frame error correction circuit may identify and correct errors in data frames provided to a receiver as part of a diversity communications scheme. The frame error correction circuit may further align the data frames so that the data frames can be compared. The frame error correction circuit may perform a bit-wise comparison of the data frames and identify inconsistent bit positions where bits in the data frames differ from one another. Once inconsistent bit positions have been identified, the frame error correction circuit may access a permutation table of permutations of bits at the inconsistent bit positions. In some implementations, the frame error correction circuit uses the permutation table to reassemble permutations of the data frames. In various implementations, the frame error correction circuit performs a CRC of each permutation of the data frames, and provides a valid permutation to a network.

Abstract: Various embodiments provide for systems and methods for signal conversion of one modulated signal to another modulated signal using demodulation and then re-modulation. According to some embodiments, a signal receiving system may comprise an I/Q demodulator that demodulates a first modulated signal to an in-phase (“I”) signal and a quadrature (“Q”) signal, an I/Q signal adjustor that adaptively adjusts the Q signal to increase the signal-to-noise ratio (SNR) of a transitory signal that is based on a second modulated signal, and an I/Q modulator that modulates the I signal and the adjusted Q signal to the second modulated signal. To increase the SNR, the Q signal may be adjusted based on a calculated error determined for the transitory signal during demodulation by a demodulator downstream from the I/Q modulator.

Abstract: An exemplary method of synchronizing a master clock and a slave clock comprises transmitting a plurality of packets between a master device and a slave device, calculating a first skew between a first pair of the plurality of packets at the slave device and a second skew between the first pair at the master device, calculating a ratio between the first skew and the second skew, providing a slave clock frequency correction to the slave device, calculating a first packet trip delay using a time that the master device initiates sending a packet to the slave device, a time the master device receives a response from the slave device, a corrected time the slave device receives the packet, and a corrected time the slave device initiates sending the response, calculating a first offset based on the first packet trip delay, and providing the first offset to the slave device.

Abstract: In some embodiments, a first RF signal is received at a wireless repeater, a signal quality is determined based on the first RF signal, the signal quality is analyzed based on a parameter, an operation mode is auto selected based on analysis of the signal quality, and a second RF signal based on the first RF signal is generated for transmission according to the selected operation mode. Under one mode, a first RAC of the wireless may generate data based on a first IF signal downconverted from a first RF signal. Based on the data, a second RAC of the wireless repeater may generate a second IF signal, which can be used to generate a second RF signal for transmission. Under another mode, the first RAC may provide the IF signal to the second RAC, which provides the IF signal for generation of the second RF signal.

Abstract: Various embodiments provide for waveguide assemblies which may be utilized in wireless communication systems. Various embodiments may allow for waveguide assemblies to be assembled using tools and methodologies that are simpler than the conventional alternatives. Some embodiments provide for a waveguide assembly that comprises a straight tubular portion configured to be shortened, using simple techniques and tools, in order to fit into a waveguide assembly. For instance, for some embodiments, the waveguide assembly may be configured such that the straight portion can be shortened, at a cross section of the portion, using a basic cutting tool, such a hacksaw. In some embodiments, the straight portion may be further configured such that regardless of whether the straight tubular portion is shortened, the waveguide assembly remains capable of coupling to flanges, which facilitate coupling the straight tubular portion to connectable assemblies, such as other waveguide assemblies, radio equipment, or antennas.
