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 BLE-Mesh device includes a controller, an RF driver for driving the transceiver adapted to be coupled to an antenna, and a counter. The controller implements an applications layer including BLE and Mesh Applications, and a BLE stack and a mesh stack. A redundant traffic suppression relaying algorithm is for waiting for a random time within a selected time window from W1 to a later W2 before attempting to transmit a first packet that has the first relay device's sender's source (SRC) address and a sequence (SEQ) number. If during the random time a packet with both the device's SRC address and the SEQ number is received, the counter is incremented from an initial count to a current count. After the random time elapses, the current count is compared to a Cthreshold value, and the first packet is transmitted only if the current count

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.

Abstract: A network includes a plurality of parent nodes to communicate in a wireless network via a wireless network protocol. A network node establishes a network connection to one of the parent nodes of the plurality of parent nodes in response to received beacons from the parent nodes. A signal analyzer in the network node processes a received signal strength of the beacons and the number of beacons received over a given time period from each of the parent nodes. The signal analyzer selects the parent node by analyzing the received signal strength for a number of beacons received from each parent node with respect to a number of expected beacons transmitted from each parent node of the plurality of parent nodes over the given time period.

Abstract: A BLE-Mesh device includes a controller coupled to a memory and to a transceiver adapted to be coupled to an antenna, wherein the controller implements an applications layer including BLE and Mesh applications, and a BLE stack and a mesh stack. The BLE-Mesh device has a switchable high-speed and low-speed mode and a speed switching algorithm for implementing a method of communications in BLE-mesh network. A broadcast ping is sent to neighborhood devices with a time to live (TTL)=1. A manufacturer's ID is analyzed to identify in a manufacturer's ID field in pongs received to determine a higher-speed capable device or a lower-speed device. A higher-speed data rate is utilized for mesh communications if a percentage of higher-speed capable devices is≧a threshold percentage or a lower-speed data rate is utilized for the mesh communications if the percentage of higher-speed capable devices is
