1. A radio system comprising:
- a network subsystem for permitting communication between users;
at least one subscriber terminal coupled to the network and having a fixed location; and
a bi-directional radio connection between the subscriber terminal and the network subsystem, the bi-directional radio connection utilizing oriented antenna beams;
the network subsystem comprising (i) at least one common measuring unit to measure parameters of a bi-directional test radio connection of a new user, (ii) means for storing the parameters of the test radio connection, and (iii) means for utilizing the parameters of the test radio connection stored in the network subsystem when the bi-directional radio connection is set up between the network subsystem and a subscriber terminal.

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.

9. A method for setting up a bi-directional radio connection utilizing oriented antenna beams between a network subsystem and a fixed location subscriber terminal in a radio system, comprising:
-
setting up a bi-directional test radio connection if a user is new; measuring the parameters of the new user'"'"'s test radio connection; storing the measured parameters; retrieving the stored parameters if the user is not new; and setting up the bi-directional radio connection by means of the retrieved parameters. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
