This paper presents a real-time utility based procedure for antenna tilt control in cellular networks. The method's convergence to Nash equilibrium is guaranteed by the concave dependence between utility function and tilt angle. The solution was verified using a CDMA motion simulator with real path-loss data collected in downtown Delhi. The simulations show a significant reduction in dropped calls when the tilt is adapted to changes in traffic. This solution can be realized on systems that install remote control antennas.
