Abstract:
The invention relates to a method for the telecommunication of data by frequency hopping in a first frequency band, wherein the frequency hops follow a predetermined time sequence, known at least to a data transmitter, characterized in that it comprises the following steps implemented by said data transmitter: defining, from a pseudo-random sample, successive values of respective differences in frequency (Δfs1, Δfs2, Δfs3, . . . ; Δfd1, Δfd2, Δfd3, etc.) in order to determine the hopping time sequence starting at a first frequency (f1), transmitting to at least one data receiver          at a first frequency (f1), said first frequency being randomly selected (S 1 ) within the first frequency band, then at successive frequencies (S 5 ) which, starting at the first frequency, comply with said successive values of respective differences in frequency, said successive values of differences in frequency defining, at reception, a succession of reception frequencies for useful data to be received from said data transmitter.

Claim (Index 11):
A method for the telecommunication of data by frequency hopping in a first frequency band, wherein the frequency hops follow a predetermined time sequence, known at least to a data transmitter, characterized in that it comprises the following acts implemented by said data transmitter:\n defining, from a pseudo-random sample, successive values of respective differences in frequency (\u0394fs1, \u0394fs2, \u0394fs3, . . . ; \u0394fd1, \u0394fd2, \u0394fd3, . . . ) in order to determine the hopping time sequence starting at a first frequency (f1), transmitting to at least one data receiver\n at a first frequency (f1), said first frequency being randomly selected (S 1 ) within the first frequency band, \n then at successive frequencies (S 5 ) which, starting at the first frequency, comply with said successive values of respective differences in frequency, said successive values of differences in frequency defining, at reception, a succession of reception frequencies for useful data to be received from said data transmitter; \n wherein the transmitter sends: synchronization data at the first frequency (fs1=f1), then at a first set of successive frequencies (fs2, fs3, . . . ) with differences in frequency (\u0394fs1, \u0394fs2, \u0394fs3, . . . ) between the successive frequencies of this first set, starting at the first frequency, which are representative of said successive values of respective differences in frequency of the time sequence (\u0394fd1, \u0394fd2, \u0394fd3, . . . ), then useful data, at the first frequency (fd1=f1) then at a second set of successive frequencies which, starting at the first frequency, comply with said successive values of respective differences in frequency of said time sequence (\u0394fd1, \u0394fd2, \u0394fd3, . . . ) wherein a receiver, to which data is to be sent, scans the first frequency band (S 21 ) to identify the first frequency (S 24 ) and a first portion at least of said successive frequencies which, starting at the first frequency, comply with said successive values for the respective differences in frequency (\u0394fi, \u0394fi+1, . . . ), said first portion at least of said successive frequencies allowing the receiver to identify (S 28 ) the succession of reception frequencies for useful data to be received from the data transmitter; wherein the receiver is connected to a database (DB) storing pseudo-random samples defining sequences used in transmission by one or more transmitters, and wherein, on the basis of said first portion at least of said successive frequencies, the receiver: determines successive differences in frequency (S 25 ) starting at the first frequency identified by scanning the first frequency band (S 24 ), compares (S 27 ) said successive differences in frequency, to differences in frequency of sequences corresponding to the pseudo-random samples stored in the database, and identifies (S 28 ), on the basis of said comparison, the time sequence used by the transmitter for receiving (S 30 ) useful data on the successive frequencies of the sequence thus identified, wherein the database stores pseudo-random samples defining sequences used for the transmission of synchronization data, and wherein the transmitter and receiver use a predetermined rule (F), known to the transmitter and receiver, to define a sequence for respectively transmitting (S 9 ) and receiving useful data based on a sequence used for the transmission of synchronization data.
