The invention concerns a method of transmitting non-dated digital data between a transmitter and a receiver in which the data can take at least two different paths between the transmitter and the receiver and handover from one path to another occurs during transmission. In the transmitter, packets intended for the second path are transmitted only after the last packet intended for the first path has been transmitted and in the transmitter and in the receiver packets on the first or second path are delayed in order for packets on the second path to arrive after packets on the first path. It is therefore not necessary to transmit signaling to differentiate the two paths at the receiver, which can include a single demodulator.

Packet mode telecommunications method and system in which calls can be handed over from one path to another

A method of controlling power in a transmission link between a central station and a terminal in a point to multi-point communication network and system for carrying out the method, particularly suitable for implementation in satellite access networks or terrestrial point to multi-point access networks. A transmitter transmits a plurality of reference signals ( ) to a plurality of receivers ( ); each receiver ( ) measures the respective quality of the signals so as to determine a reference signal ( ) corresponding to the receiver ( ); each receiver ( ) indicates to the transmitter ( ) the reference signal ( ) corresponding thereto; and if required, the transmitter ( ) adjusts the power level of transmission of the traffic data ( ).
