A method determines a quality of a communication connection between a selected secondary station and a main station of a radio-operated multi-hop hazard reporting system. The method includes the determination of a value of a first parameter for the selected secondary station, the value of the first parameter is indicative of the connection security only between the selected secondary station and the main station. The method further includes a determination of a value of a second parameter for the selected secondary station, wherein the value of the second parameter is indicative of the connection security only between any directly adjacent secondary stations of the selected secondary stations and the main station, and a determination of the quality of the communication connection based only on the value of the first parameter and the value of the second parameter.

Quality assessment of a communication connection in a radio-operated multi-hop hazard reporting system

A method and a system for the propagation of a message in a radio-operated communication network having a base unit and a plurality of members, wherein the base unit and the members each includes a transmitter and a receiver, the receiver being activated at cyclical switch-on times for a certain respective receiving period. A message to be sent from a member to the base unit is transmitted by the member to at least one adjacent member as a function of at least one rule, and the message is transmitted by the at least one adjacent member, according to the at least one rule, to at least one member adjacent thereto, in the direction of the base unit. The process is repeated such that the message is transmitted from at least one adjacent member receiving the message according to the at least one rule to at least one member adjacent thereto, in the direction of the base unit. The message is transmitted from the at least one member that is adjacent to the base unit to at least the base unit.
