Abstract: A network includes a mobile network node (MNN) that includes a mobile node communications manager (MNCM) to facilitate wireless communications to a plurality of stationary network nodes (SNNs) in a wireless network via a wireless network protocol. The MNCM utilizes a multicast address received over the wireless network. The multicast address is assigned to a predetermined network time slot to communicate uplink data from the MNN to the SNNs. The MNN receives downlink data via a separate predetermined network address and time slot assigned to a given SNN.

Abstract: A method for pseudo channel hopping in a node of a wireless mesh network is provided that includes scanning each channel of a plurality of channels used for packet transmission by the node, wherein each channel is scanned for a scan dwell time associated with the channel, updating statistics for each channel based on packets received by the node during the scanning of the channel, and selecting a channel of the plurality of channels for scanning based on the statistics when the scan dwell time of a currently scanned channel ends.

Abstract: In an example method of target position estimation, the method includes calculating initial estimated positions of a target transmitter. Each of the initial estimated positions is based on an angle of arrival estimate received from a locator. The method includes generating an error projection associated with each of the initial estimated positions. The error projection is based on azimuth and elevation error characteristics of the locator associated with the initial estimated position. The method includes creating a select group of the locators based on overlaps of the error projections, wherein the select group of locators comprises a subset of the locators. The method includes calculating a refined estimate of the position of the target transmitter based on the initial estimated positions associated with the select group of locators.

Abstract: An electronic device includes a printed circuit board (PCB) with electronics configured to generate and receive data by a radio-frequency carrier signal via a signal terminal. A monopole antenna having first and second ends is connected to a signal terminal of the PCB at the first end. A first section of the antenna extends away from the signal terminal by a first length in a first direction. A second section of the antenna extends away from the first section by a second greater length in a second direction different from the first direction. The first section is spaced apart from the PCB by a third section of the antenna, and the second end of the antenna is spaced apart from the PCB by a dielectric spacer. The length of the antenna may be ¼ of a carrier frequency provided by the signal terminal.
