ABSTRACT:
The invention relates to a radio system where oriented antenna beams are used over a radio connection between a network subsystem and a subscriber terminal with a fixed location. The network subsystem comprises means for storing parameters of a bidirectional radio connection, including e.g. the transmit beam angle, the receive beam angle, the air interface delay profile, the air interface impulse response, the transmit power of the network subsystem, the transmit power of the subscriber terminal, and the number of rake branches. The network subsystem also comprises a common measuring unit that measures parameters of a bidirectional test radio connection of a new user.
