Abstract
The invention relates to a repeater arrangement for amplifying a communication link between a base station and user equipment, wherein the communication link comprises an uplink and a downlink utilizing frequencies within a coherence bandwidth. The repeater arrangement comprises: a first antenna for communication with the base station; a second antenna for communication with the user equipment; an amplifying device operatively connected to the first antenna and to the second antenna for conveying and amplifying communication signals between the first antenna and the second antenna, the amplifying device comprising a first signal path for the uplink and a second signal path for the downlink, the first and second signal paths having equal electrical length, in order to affect said communication signal identically in both uplink and downlink, providing same phase and amplitude characteristics to said communication signal.
