In a wireless local area network that includes high-throughput communication devices with multiple antennas and legacy communication devices with single antennas, training tones are transmitted over a plurality of spatial channels during a first portion of an orthogonal frequency division multiplexed packet-training preamble. Each of the panel segments includes a fluted core sandwiched between first and second facesheets. The sensor system is configured to determine a temperature of the distribution transformer, and the communications module is configured to transmit a load reduction request along the low voltage line to the electrical device based on the temperature of the distribution transformer. The receiving device calculates a quality of slot score for each slot that it receives data for. Some further embodiments also use results from cloud-based tools to initiate local virtual machine tool platforms that are used to further analyze traffic of interest. The control member performs preset driving control of the driving member on the basis of the preset information stored in the storage member.
