Abstract
An apparatus, a method and a computer program for characterizing antenna units in a predefined space. The antenna units provide coverage with radio services for a mobile transceiver in the space. An antenna unit is operated in two modes of operation, sending and receiving. At least one first antenna unit has multiple radiation characteristics. The method includes operating the first antenna unit in a first mode of operation and operating a second antenna unit in the second mode of operation and varying the radiation characteristics of the first antenna unit and capturing information about transmission properties between the first antenna unit and the second antenna unit for the radiation characteristics. The method also includes characterizing the antenna units based on the information about the transmission properties.
