Training: Capacity Management (Radio - Transmission - Core)

Capacity is the most issue in Network Planning and Optimization activities. Capacity problem impact Network KPI mostly in accessibility, give contribution in retainability degradation (ex. increasing drops) and integrity degradation (ex. low throughput). This training will give detail explanation to design capacity both in 2G & 3G networks in three main area : Radio, Transport and Core Network, also explain strategy to handle future traffic increment and traffic mobility.
