An apparatus and method for managing inter-personal activities to facilitate matchmaking between single individuals, by instructing each individual what to do and with whom during a series of game sessions. All the light beams from the light source devices are incident on the optical deflector in directions oblique to a normal line of the scanning surfaces in a main-scanning cross section and to a normal line of a deflecting reflection plane of the optical deflector in a sub-scanning cross section. The received indications are assigned to the user group by users associated with the user group, and the received indications reflect a desire by the users for a special treatment of future calls from the call source. To be able to transmit simultaneously in an arbitrary combination of more than one beam, the BS antenna array includes a separate feeder cable for each combination of beams corresponding to a particular polarization, from one feeder per beam to one feeder with all beams of that polarization.
