Dears,
I have WCDMA coverage problem. Before is was enough for our city, but now it is down everywere. We did following actions.
1. We upgraded RNC and NodeB R10 to R12(BSC6810 to BSC6900 huawei). but BTS transmittion power is same for R10.
2. CS and PS traffic is increased 5 times. Now i have several cells that is code congestion and 2 cells have power congestion. But average cell capacity usage is approximately 80%.
We didn't change antenna downtilt and direction.
What happened my network? Is is possible increased traffic is affecting our coverage? What i need to do?
Please share with me your experience.
Best regards,
Magno
