Abstract:
1. A method for resolving contention among the signals traveling between a base and a plurality of remotes and among the signals from the plural remotes, in the process to register the remotes into a data network having a pre-determined number of network slots, said method utilizing radio frequency signals and comprising the steps of: Broadcasting a hail signal from the base to initiate the registration process, said hail signal being intended for the remotes; Allowing a pre-selected hail time to expire; Calculating at the base maximum time delay signal, said time delay signal to be used by the remotes in responding to the base; Transmitting said maximum time delay signal to the remotes; Issuing a synchronization signal to the remotes; Accepting at one or more remotes said maximum time delay signal and calculating therefrom a new random delay, said random delay having a time value ranging between “0” and said maximum; Waiting for said synchronization signal to complete and said random delay to expire; Sending to the base a response from one or more remotes, said response containing therein the unique address of its respective remote; Receiving at the base said responses from one or more remotes and registering said remotes into the data network; Conveying acknowledgment signals to the remotes, said acknowledgment signals indicating the registration of said remotes into the data network; and Exiting the registration process.
