Abstract: Routing system is disclosed. The system comprises one or more head devices participating in routing operations and one or more destination devices. Each head device has one or more member devices. At least one head device is configured to in response to receiving from a member device an uplink data packet DPU, forward the DPU and store into a routing table linkage information representing a linkage of a destination device generated the DPU to the member device. In response to receiving a downlink data packet DPD addressed to a destination device, forward the DPD only to its member device to which the destination device, to which the DPD is addressed, is linked based on the routing table, if linkage information related to the destination device, to which the DPD is addressed, is stored in the routing table. Also routing methods, head device, computer program, and computer readable medium are disclosed.

Abstract: The application relates to a configuration system (100) for a wireless communication network (102) that comprises at least one first communication device (104b) and at least one second communication device (104c). The at least one first and second communication devices (104b, 104c) belong to a plurality of communication devices (104, 104a, 104b, 104c, 104d). Each communication device (104, 104a, 104b, 104c, 104d) in the plurality of the communication devices is a radio node device configured to provide a bi-directional radio communication with at least one of the plurality of the communication devices.

Abstract: Disclosed is a wireless mesh network that includes a first node node and at least one second node. The first node is configured to provide a bi-directional mesh communication to the at least one second node. The first node is configured to broadcast a beacon periodically. The at least one second node is configured to sent a data frame to the first node. The data frame is encrypted by way of an Initialization Vector, which has been composed from at least a first node-specific Super Frame Counter included into the beacon, a Sender-Node-Specific-Frame Counter, and an identification of a sender.

Abstract: The invention relates to a wireless communication system comprising a plurality of radio devices. Each radio device belongs to one or more radio neighborhoods and is capable of repeating the transmission of the broadcast message regardless of whether the radio device is operating as a router device or as a non-router device. The radio devices belonging to each radio neighborhood are configured to repeat collectively a transmission of a broadcast message a collective target amount of repetitions within each radio neighborhood. Each radio device within each radio neighborhood to which it belongs is arranged to: define a total repetition load value representing a contribution of said radio device to the collective target amount of repetitions of the broadcast message within said radio neighborhood, and decide whether to repeat the transmission of the broadcast message in accordance with the defined total repetition load value.

Abstract: Disclosed is a wireless communication system, including one or more monitoring devices and one or more asset tag devices. The one or more monitoring devices are configured to: transmit a beacon frame on at least one first communication channel and listen to the second communication channel. The one or more asset tag devices are configured to: scan at least one first communication channel to receive at least one beacon frame; select a monitoring device; switch to the second communication channel indicated in the beacon frame; and initiate communication with the selected monitoring device on the second communication channel. The selected monitoring device is further configured to communicate with the one or more asset tag devices on the second communication channel. Also disclosed are discovery methods, an asset tag device and a monitoring device for the wireless communication system.

Abstract: Disclosed is a system for co-operative repetition of broadcast messages comprising a plurality of router nodes, each being able to receive and repeat transmission of broadcast messages. The plurality of router nodes is configured to repeat collectively a transmission of a broadcast message on one or more frequency channels a collective target amount of times inside a neighborhood of the plurality of router nodes. The amount of repetitions of individual router nodes differs from 0 to n, wherein n>0, in order to achieve the collective target amount of repetitions.
