The Effects of Antenna Orientation Errors on UMTS Network Performance
E. Dinan, Aleksey Kurochkin · 2006
Inconsistencies in setting up antenna azimuth and tilt during installation may reduce overall network performance. However, the degree of quality degradation depends on the amount of the discrepancy between the designed and installed parameters. The paper investigates the effect of these errors on UMTS RAN key performance indicators, including coverage, signal quality (EC/I0), and soft-handoff areas. Two examples are studied that include real field tests and measurement data. The studies show the effect of azimuth and tilt installation inaccuracies on UMTS network quality
