The achievable throughput of the entire cellular area is investigated, when employing fractional frequency reuse techniques in conjunction with realistically modelled imperfect optical fibre aided distributed antenna systems (DAS). Given a fixed total transmit power, a substantial improvement of the celledge area's throughput can be achieved without reducing the cellcentre's throughput. The cell-edge's throughput supported in the worst-case direction is significantly enhanced by the cooperative
