The method is performed by relaying data to a central site from locality-distributed data-recording sites (D1-D5) via a relay or bridging station when direct reception fails or is unreliable. The central station retrieves by radio, and stores, data from the data site. If entire data sites are not reached by the central site, the central site transmits to the achievable data sites or makes further attempts by those relay or bridging places which can be reached. The reached data places, or relay or bridge sites, thereupon try to relay the data from the initially unreached data site, either directly or indirectly by radio and retransmit to the central station. An Independent claim is included for a central recording system. |
