OBJECTIVE
› This presentation intend to show how to change the site frequency through command line.
› The example show in the presentation is:– Utrancell: WJUC11 / WJUC12 / WJUC13– Uarfcn: DL=10787; UL=9837– Frequency: HighEdge=21599; LowEdge= 21549
› In the scripts are considered that the confirmation at RNC and NodeB is disable. Thus, any yes confirmation is needed.
