Data communication radio network
First Claim
1. A data communication radio network (11) with bidirectionally operating data collectors (13) which communicate data telegrams (18) from data-generating terminal devices (12) to a data-documenting master data collector (14), characterised in that the data collectors (13) determine distribution criteria in respect of the respective primary radio section (10) between a terminal device (12) and a first data collector (13) in the network (11) and communicate same to the master data collector (14), on the basis of which an association of the transmission of the original data telegram (18) from a terminal device (12) by way of its primary radio section (10) is effected singularly with one and only one of the data collectors (13), with which also other terminal devices (12) can be singularly associated and which also receives distribution criteria belonging to other terminal devices (12) not associated with it and makes same available to the master data collector (14).

Abstract
In the wireless telegram communication (28) from data-generating, unidirectionally communicating terminal devices (12) by way of primary radio sections (10) and by way of subsequent bidirectionally operating data collectors (13) of a radio network (11) to a data-documenting master data collector (14), a memory and selection expenditure governed by redundancy as a consequence of multiple connections by way of the primary radio sections (10) is avoided and nonetheless very reliable telegram communication (18) is achieved with simplified data collectors (13) if distribution criteria such as for example reception field strength-dependent quality information (22) is currently detected and stored in data collectors (13) for primary radio sections (10) from terminal devices (12). In dependence on the instantaneous distribution criteria for each terminal device (12) the master data collector (14) implements a quasi-stationary association with one and only one of the data collectors (13) for the subsequent telegram communications (18), until for example periodically or in an event-controlled manner a new association of a terminal device (12) is again implemented with one and only one, possibly a different one of the data collectors (13). The data collectors (13) also operate with each other as relay stations (25) for forwarding the data telegrams (18) to the master data collector (14) and are equipped, to prevent telegram doublets occurring on different routes, with a barrier against the same data telegram (18) being read out a plurality of times.
