A determination of whether the first data rate exceeds the backhaul data rate is made and an excess data rate is determined. When the first data rate exceeds the backhaul data rate a neighboring cell site having a second backhaul networks is accessed. A determination is made of how much additional capacity the second backhaul network can handle. When the neighboring cell site can handle the excess data rate backhaul sharing using beamforming is initiated.
