Software-updating method for a wireless communication network

A software-updating method for a wireless communication network including radio nodes including a first radio node and a plurality of second radio nodes, the radio nodes providing a bi-directional radio communication between each other, said method comprising:

• receiving, by the radio nodes, a software-distribution package;
• sending, by each of the second radio nodes having received and stored the software-distribution package, an indication to the first radio node indicating that the software-distribution package is received and stored;
• sending, by the first radio node, after the first radio node has received the indication that the software-distribution package has been received and stored from each of the second radio nodes that has received and stored the software-distribution package to each of the second radio nodes having sent the indication, a timer frame indicating timing information that indicates a moment of time when each of the second radio nodes that has sent the indication, and the first radio node are to start to execute the received software-distribution package to simultaneously update a software of the radio nodes;
• receiving, by at least the second radio node, the timer frame;
• and
• simultaneously updating, by each of the first radio node and each of the second radio nodes, which has sent the indication, the software of the radio nodes at the indicated moment of time.

A radio node device for a wireless communication network, the radio node device comprising:

• a microcontroller;
• and
• a radio transceiver,
• wherein the radio node device is configured to
• provide, by the radio transceiver, a bi-directional radio communication with a plurality of other radio node devices,
• receive, by the radio transceiver, a software-distribution package,
• receive, by the radio transceiver, an indication indicating that the software-distribution package is received and stored from each of the other radio node devices having received and stored the software-distribution package,
• send, by the radio transceiver, after the radio node device has received the indication that the software-distribution package has been received and stored from each of the other radio nodes that has received and stored the software-distribution package to each of the other radio node devices having sent the indication, a timer frame indicating timing information that indicates a moment of time when each of the other radio node devices that has sent the indication, and the radio node device are to start to execute the received software-distribution package to simultaneously update a software of the radio node devices, and
• update, by the radio node device simultaneously with each of the other radio node devices, which has sent the indication, the software of the radio nodes at the indicated moment of time.
