Optimizing in Two Worlds

Circuit-Switched Voice Traffic

• Some operators are implementing 1xRTT mainly to gain capacity for additional voice traffic
• Their optimization techniques remain about the same as for 2G voice networks today - Keep network adequately dimensioned – Control RF environment – Monitor and manage capacity utilization
  

IP Data Traffic

• Operators adding IP traffic to upgraded voice networks
• Conventional optimization techniques are still appropriate for general
  

RF environment and circuit-switched network performance

• New IP and QoS issues require a new optimization focus for the blended total network - IP performance depends on both IP and RF factors - IP and Voice performance involve competitive tradeoffs
