A method for configuring a wireless conferencing system comprising a plurality of conference terminals in an indoor environment, each of said conference terminals being equipped with a transceiver adapted to operate in a first mode and a second mode, said first mode being an omnidirectional mode and said second mode being a directional mode, the method comprising: - in a discovery phase, for each pair of conference terminals, discovering a number of directions in which a direct wireless exchange of signals between said pair of conference terminals is possible, by operating a first one of said pair of conference terminals in said first mode and a second one of said pair of conference terminals in said second mode and attempting to exchange first signals while said transceiver of said second conference terminal is operated so as to vary a direction of operation; - for a first one of said plurality of conference terminals and a second one of said plurality of conference terminals, selecting a first one of said number of directions in which said direct wireless exchange of signals between said first one of said plurality of conference terminals and said second one of said plurality of conference terminals is possible as an active transmission direction; - in an operational phase, sending second signals from said first one of said plurality of conference terminals to said second one of said plurality of conference terminals, using said active transmission direction; and, - in a primary recovery phase, if a failure in said sending of said second signals is detected and if said discovering resulted in at least two directions in which said direct wireless exchange between said first one of said plurality of conference terminals and said second one of said plurality of conference terminals is possible, selecting a second one of said number of directions in which said direct wireless exchange of signals between said first one of said plurality of conference terminals and said second one of said plurality of conference terminals is possible as a new active transmission direction, and sending third signals from said first one of said plurality of conference terminals to said second one of said plurality of conference terminals, using said new active transmission direction. - in a discovery phase, for each pair of conference terminals, discovering a number of directions in which a direct wireless exchange of signals between said pair of conference terminals is possible, by operating a first one of said pair of conference terminals in said first mode and a second one of said pair of conference terminals in said second mode and attempting to exchange first signals while said transceiver of said second conference terminal is operated so as to vary a direction of operation; - for a first one of said plurality of conference terminals and a second one of said plurality of conference terminals, selecting a first one of said number of directions in which said direct wireless exchange of signals between said first one of said plurality of conference terminals and said second one of said plurality of conference terminals is possible as an active transmission direction; - in an operational phase, sending second signals from said first one of said plurality of conference terminals to said second one of said plurality of conference terminals, using said active transmission direction; and, - in a primary recovery phase, if a failure in said sending of said second signals is detected and if said discovering resulted in at least two directions in which said direct wireless exchange between said first one of said plurality of conference terminals and said second one of said plurality of conference terminals is possible, selecting a second one of said number of directions in which said direct wireless exchange of signals between said first one of said plurality of conference terminals and said second one of said plurality of conference terminals is possible as a new active transmission direction, and sending third signals from said first one of said plurality of conference terminals to said second one of said plurality of conference terminals, using said new active transmission direction.
