A method for transmitting data packet blocks over multiple frequency channels (16, 24) is described, the frequency channels (16, 24) being at least in part already used in an existing basic network (10) for digital data and/or voice transmission. In a first step a frequency channel (16, 24) currently unoccupied by the basic network (10) is identified, whereupon in a second step a data packet block is transmitted over the identified frequency channel (16, 24). These steps are cyclically repeated, in the manner of a frequency-hopping technique, until all the data packet blocks of a transmission have been transmitted. A corresponding subscriber unit for an auxiliary network (21) with multiple subscriber units (23) is also described, the subscriber unit (23) transmitting the data packet blocks, in accordance with the frequency-hopping technique, in temporally staggered fashion on frequency channels (16, 24) unoccupied at the time by the basic network (10).

[ I claim:] [1.] A method of transmitting data packet blocks over multiple frequency channels that at least in part are already being used in an existing basic network for digital data and/or voice transmission, the transmission occurring in an auxiliary network between multiple subscriber units each of which has its own address that is known to other subscriber units, comprising the steps:1) identify a frequency channel currently unoccupied by the basic network, based on signals that are received and suitably analyzed by any one subscriber unit in the auxiliary network;2) transmit a data packet block over the identified frequency channel; and3) cyclically repeat steps 1) and 2), in the manner of a frequency-hopping technique, until all the data packets blocks of a transmission have been transmitted.
