20080274693 | Method for Selecting the Installation Position and Direction of Link Antenna in Inbuilding Radio Frequency Repeater and Cable Apparatus Used in the Same - The present invention relates to a method for selecting an installation position of a link antenna of an in-building RF repeater, a cable device thereof, and a terminal. The method selects the position for measuring the greatest Ec/lo by using directivity of the link antenna in an area for installing the link antenna. The link antenna is installed at the selected position. The direction with the greatest Ec/lo that is measured by using directivity of the link antenna is fixed to be a desired direction from among target directions to be directed by the link antenna. In this instance, measurement of Ec/lo by using directivity of the link antenna is performed by a mobile station connected to the link antenna through an access cable. Accordingly, the link antenna can be installed at the optimized position and in the optimized direction. Hence, the Ec/lo within the building is substantially reduced. | 11-06-2008 |
