<p>A multi-antenna transmission process is described for providing down-link radio coverage from radio base station to mobile terminal in a network for radio mobile communications through a transmission system comprising: at least one multi-radiator transmitting antenna, in particular a Smart Antenna or an Array Antenna, directed towards at least one mobile terminal; at least one database associated with at least one coverage cell of said mobile communications network and containing information about a position of said mobile terminal; processing means cooperating with said at least one multi-radiator transmitting antenna and said at least one database, said processing means being adapted to associate a transmission direction with said position of said mobile terminal, wherein said transmission direction is suitable for reaching said mobile terminal, comprising the steps of: a) detecting a position of said mobile terminal; b) storing said position into said at least one database; c) determining at least one transmission direction of at least one transmission beam from said at least one multi- radiator transmitting antenna to said mobile terminal depending on said position stored in said at least one database, wherein at least one of the transmission parameters that must be set in the at least one multi-radiator transmission antenna in order to transmit in said transmission direction is associated with said stored position of said mobile terminal.</p> |
