Method for establishing radiofrequency communication between what is termed a slave terminal and what is termed a master terminal of a DECT communication network, each terminal being equipped with a plurality of antennae and including means for measuring the power level of a signal received by each antenna and means for selecting one of these antennae as a reception antenna by comparing the power levels thus measured, said master terminal being intended to broadcast a beacon signal with which said slave terminal time-synchronizes and frequency-synchronizes itself, said method including: - a step of continuous broadcasting of a beacon signal by the master terminal, - a step of seeking to time-synchronize and frequency-synchronize said slave terminal with the master terminal, - a step of synchronizing the slave terminal with the master terminal, - a step of transmitting a radio resources allocation request signal, - a step of reception, by the master terminal, of the radio resources allocation request signal, - a step of transmission, by the master terminal, of the allocated radio resources, and a step of exchanging traffic signals between the master terminal and the slave terminal, during which, upon each reception of a traffic signal by either the slave terminal or the master terminal, a receiver terminal tests whether more than one antenna receives a traffic signal and then selects the reception antenna to be the one on which the measured power level of the received signal is highest, characterized in that - during the step of seeking to synchronize with the master terminal, each antenna of a slave terminal is considered in turn for a predetermined period and, during each period, it is checked whether a beacon signal transmitted by the master terminal is received by the antenna under consideration during this period and, if an antenna receives the beacon signal transmitted by the master terminal, the antenna is determined as being the reception antenna of the slave terminal, - during the step of transmitting a radio resources allocation request signal, the slave terminal transmits the radio resources allocation request signal via the antenna determined in step as being the reception antenna, - during the step of reception, by the master terminal, of the radio resources allocation request signal, the master terminal tests whether more than one antenna receives the radio resources allocation request signal and then selects, as reception antenna, the antenna on which the measured power level of the received signal is highest, and I - during the step the master terminal transmits the allocated radio resources via the antenna selected in step of reception of the radio resources allocation request signal. - a step of continuous broadcasting of a beacon signal by the master terminal, - a step of seeking to time-synchronize and frequency-synchronize said slave terminal with the master terminal, - a step of synchronizing the slave terminal with the master terminal, - a step of transmitting a radio resources allocation request signal, - a step of reception, by the master terminal, of the radio resources allocation request signal, - a step of transmission, by the master terminal, of the allocated radio resources, - during the step of seeking to synchronize with the master terminal, each antenna of a slave terminal is considered in turn for a predetermined period and, during each period, it is checked whether a beacon signal transmitted by the master terminal is received by the antenna under consideration during this period and, if an antenna receives the beacon signal transmitted by the master terminal, the antenna is determined as being the reception antenna of the slave terminal, - during the step of transmitting a radio resources allocation request signal, the slave terminal transmits the radio resources allocation request signal via the antenna determined in step as being the reception antenna, - during the step of reception, by the master terminal, of the radio resources allocation request signal, the master terminal tests whether more than one antenna receives the radio resources allocation request signal and then selects, as reception antenna, the antenna on which the measured power level of the received signal is highest, and I - during the step the master terminal transmits the allocated radio resources via the antenna selected in step of reception of the radio resources allocation request signal.
