Claim Text:
1. A communication terminal, comprising: a digital communication circuit utilizes a time division multiplexing on a single radio channel, selectable in a given frequency band, the communication terminal implements a wireless communication in conference and hands-free mode on an autonomous network between at least two wearers of similar communication terminals, the digital communication circuit is configured so that each frame transmitted contains both an order number of the communication terminal in a group and an ordered chaining data of the order numbers of the communication terminals synchronized with each other for the group comprising more than three communication terminals; an automatic synchronizer synchronizes to a signal of any of other communication terminals in the group of terminals, synchronizes an internal time reference, thus a periodic cycle time, to a time reference common for all terminals of the group, the synchronization being based on the order number of a transmitting terminal present in a frame, and calculates a transmission time slot in the periodic cycle time of the time division multiplexing in accordance with the order number; and wherein the automatic synchronizer conducts re-synchronizations by resetting its internal clock to that of a receiving terminal of the group from which it has received a frame, when the group is composed of more than three communication terminals, the automatic synchronizer implements resynchronization in accordance with the order number of the transmitting terminal and the ordered chaining data of order numbers of the terminals synchronized with each other.
