“…The authors show that even with uniform traffic the optimization provides a set of network configurations with a larger capacity-coverage tradeoff. The effect of electrical and mechanical antenna down-tilting in UMTS networks is presented in [3]. In this paper the authors demonstrate the need for adapting antenna settings to the expected traffic distribution and cell size.…”

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.

“…In [8] GSM system performance improvement with antenna tilting has been discussed. In [9] and [10,11] focus is on UMTS and LTE system performances respectively, with regard to antenna tilting. Tilting plays a crucial role in interference management [12], improves the conditions for handover by minimizing unwanted overlapping with neighboring cells [13].…”

“…The antenna tilt angle of wireless base-stations is known to impact cell coverage and interference management in existing cellular networks [1], [2]. In this paper we investigate the role of tilt angle adjustment in next generation LTE networks where SIMO receivers and adaptive OFDM/TDMA transmission scheduling may additionally be used to mitigate interference [3].…”

Abstract-In this paper we investigate the role of tilt angle adjustment in next generation LTE networks where SIMO receivers and adaptive OFDM/TDMA transmission scheduling may additionally be used to mitigate interference. We present detailed performance measurements when (i) optimal fair tilt angle adjustment is applied in combination with SIMO receivers using Linear Minimum Mean Square Error (LMMSE) detection to mitigate interference , and when (ii) tilt angle adjustment is applied in combination with proportional fair OFDM transmission scheduling which adapts the transmission rate per subcarrier (narrow-band rate allocation). We find that even when SIMO/LMMSE reception and adaptive transmission scheduling are used to mitigate interference, tilt angle adjustment still offers the potential for significant performance gains, namely increases in mean user throughput of more than 65% and improvements in the network sum-log rate of greater than 20%.
