The Impact of Antenna Tilt on UMTS Network Performance

The paper investigates the effect of antenna tilting on UMTS network performance. At first radio network planning of UMTS networks based on WCDMA technology is described. Next the dimensioning and detailed planning phases are described. Finally, the effect of antenna tilting on network coverage, capacity and interference is analyzed and based on the results, an optimum tilt angle can be found for different bit rates. All results for different services with 8, 64 and 144 Kbps bit rates are
