    Abstract: This waveguide comprises: three or more conductor layers that are stacked; two or more dielectric layers that are stacked, each being formed between two conductor layers adjacent to each other among the three or more conductor layers; and a first via group and a second via group each including one or more vias disposed in at least one dielectric layer among the two or more dielectric layers. The first via group and the second via group are arrayed in parallel. Among the vias included in the first via group and the second via group, the vias disposed in at least one of the two or more dielectric layers differ in position on the plane of the dielectric layer from the vias disposed in the remaining dielectric layer.

    Abstract: In a radio network system containing a first radio apparatus that performs central control and a second radio apparatus, the second radio apparatus receives a first signal containing first identification information indicating a transmission source during a first reception period, receives a second signal containing second identification information indicating a transmission source during a second reception period, measures first reception information on reception of the first signal, measures second reception information on reception of the second signal, and transmits first measurement information containing the first reception information and the first identification information and second measurement information containing the second reception information and the second identification information to the first radio apparatus. When the first identification information and the second identification information are the same, the first radio apparatus compares the first reception information and the second reception information to determine whether a radio apparatus in an abnormal condition is present.

    Abstract: A radio communication apparatus includes reception circuitry, which, in operation, receives a first frame transmitted by a first node in a wireless mesh network; and control circuitry, which, in operation, configures a relay destination node as second information in case that the first frame includes first information indicating a third node that performs transmission in cooperation with a second node that transmits a radio signal to a radio link in which communication quality is less than a threshold in the wireless mesh network and in case that the third node included in the first information indicates the radio communication apparatus, the relay destination node being a node to which the second node transmits the first frame, the second information indicating a relay destination node to which the third node transmits the first frame.

    Abstract: Provided is an improved estimation and identification device that estimates the position of a plurality of identification targets and identifies the plurality of identification targets. The estimation and identification device has a configuration comprising: a plurality of tracking devices that emit electromagnetic waves or sound waves and detect the position of an identification target on the basis of reflected electromagnetic waves or sound waves from the identification target holding a wireless transmission terminal; a plurality of wireless communications devices that wirelessly communicate with wireless communications terminals and receive identification information for the wireless communications terminals from the wireless communications terminals; and an analysis circuit that identifies the identification target and estimates the position of the identification target, on the basis of the results of the wireless communications results, the detected position of the identification target, and the identification information.
