The application relates to a wireless mesh communication system (100) that comprises a plurality of radio nodes (102, 104, 106). Each of the plurality of radio nodes is configured to provide a bi-directional radio communication with other radio node (102, 104, 106) of the system and to obtain (213, 216, 224) an assisted GNSS (A-GNSS) assistance data used in a global navigation satellite system (GNSS) positioning. Also, at least one (102, 104) of the radio nodes indicates (230) to other radio nodes (102, 104, 106) of the system that the A-GNSS assistance data is available and transmissible on request, if the at least one of the radio nodes has this A-GNSS assistance data.

The application relates to a double acting demolition device according to one embodiment for demolishing structures. The device includes a first crushing jaw for crushing operation, a first cutting jaw for cutting operation, and a combination jaw. The first jaws are separate jaws. The combination jaw is attachable to the first cutting jaw for constructing a second crushing jaw and to the first crushing jaw for constructing a second cutting jaw. The second crushing jaw is used jointly with the first crushing jaw in crushing operation and the second cutting jaw is used jointly with the first cutting jaw in cutting operation. In crushing operation, the first crushing jaw rotates around a fulcrum other than that of the second cutting jaw in cutting operation.

The application relates to a demolition device for demolishing a concrete structure according to one embodiment. The device has a crushing blade for crushing concrete, and a cutting blade for cutting metal or a pulverizing blade for grinding concrete, and a combination blade. The device can be attached to a utility machine in a detachable manner. The crushing and cutting/pulverizing blade are separate blades from each other. The combination blade is adapted to be used for crushing concrete with the crushing blade. The combination blade is adapted to be used for cutting metal with the cutting blade or for grinding concrete with the pulverizing blade. The combination blade has abutment surface parts for the crushing and cutting/pulverizing blade. The abutment surface part for the cutting/pulverizing blade makes possible a power transmission between the cutting/pulverizing and combination blade when using the combination blade for crushing concrete. The abutment surface part for the crushing blade makes possible a power transmission between the crushing and combination blade when using the combination blade for cutting metal or grinding concrete.
