You are in optimizing 1 new site and 4G Payload suddenly increase and impact to your CSSR KPI, what will you NOT do immediately?

• Check if any promo campaign to up the sales
• Check your validity of your measurement if any double counting
• Payload Increase is good, so make justification for CSSR KPI
• Check if any site surrounding site if shutdown

Is it possible to plot throughput with a planning tool capable of only path loss based calculations?

• 1. No, it is only possible with Monte Carlo simulations
• 2. Yes, if the tool can calculate path loss and SINR (for static load) and MAPL (from link budget) is available for different throughputs
• 1 and 3 True
• 3. No, it is not possible based on only path loss calculations
