Abstract: An association system for a wireless communication network includes an association initiator device and association target device. Each association target device transmits beacon messages including load data of the association target device including at least data indicative of number of currently associated router devices. After receiving the beacon message from an association target device, each association initiator device: decides whether to attempt to associate with the association target device on a basis of the load data included at least partly in the received beacon message from the at least one association target device, and send an association request message to each of the at least one association target device with which the association initiator device decides to attempt to associate. The application relates also to association methods for a wireless communication network, an association target device, an association initiator device, a computer program, and a computer readable medium.

Abstract: The invention relates to a wireless communication system (100) comprising a plurality of radio devices (102, 202, 204). Each of the plurality of radio devices (102, 202, 204) is capable of transmit and receive data packets (220). At least one radio device (102, 202, 204) is configured to: ACK packets (240) received from one or more neighbouring radio devices (102, 202, 204) in response to transmitted data packets (220); determine lengths of ACK gap (230) periods of the one or more neighbouring radio devices (102, 202, 204) based on the observed ACK packets (240); and adjust its ACK listening duration (250) based on the determined lengths of the ACK gap periods (230). The invention relates also to a method for a wireless communication system (100), a radio device (102, 202, 204) for a wireless communication system (100), a method for the radio device (102, 202, 204), a computer program (505), and a tangible non-volatile computer-readable medium.

Abstract: The invention relates to timing system for wireless communication network comprising plurality of communication devices. The timing system comprises at least one cluster head device associated with at least one beaconing cluster member device configured to transmit beacon messages. The at least one cluster head device and its associated at least one beaconing cluster member device belong to the plurality of communication devices of the wireless communication network. The at least one beaconing cluster member device is configured to periodically transmit a periodical message to its cluster head device. The periodical message comprises timing information indicating timing of next beacon message of the beaconing cluster member device transmitting the periodical message.

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: The invention relates to a wireless communication system (100) comprising a plurality of radio devices (102, 104). Each radio device of the plurality of radio devices (102, 104) is configured to: obtain timing information representing timing schedules of one or more other radio devices (102, 104) within its neighborhood; define, based on the obtained timing information, at least one timing schedule group (106, 108) into which the plurality of radio devices (102, 104) are divided and a size of each at least one timing schedule group (106, 108); and synchronize its own timing schedule with the timing schedule of the timing schedule group (106, 108) with the largest size. The invention relates also to a synchronization method (500) for the wireless communication system (100), a radio device (102, 104) for a wireless communication system, and a synchronization method for the radio device (102, 104).

Abstract: Disclosed is a wireless communication network including radio nodes, which include a first radio node and a second radio node. The nodes are configured to provide a bi-directional radio communication between each other. The nodes are configured to receive a software-distribution package. In addition, the first node sends to at least the second node a timer frame indicating when all nodes of the network start to execute the received package in order to update a software of the nodes.

Abstract: The invention relates to a wireless communication system (100), comprising a plurality of radio nodes, each being able to operate at least as a router node (104) or as a non-router node (104). Each of the plurality of radio nodes is configured to: detect density of the router nodes (104) within its neighbourhood, and make a decision based on the detected density whether to operate as a router node (104) or as a non-router node (106). The invention relates also to a role selection method and a radio node device (104, 106, 500) for the wireless communication system (100).
