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

Decentralized synchronization solution for wireless communication networks

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.

Software-updating method for a wireless communication network

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