Tuning or Optimization, What is the difference!
(cid:131) During Tuning
No traffic in the network, No subscribers
Network tuned only based on drive test data
Labor intensive with repeated drive test
All is about Pre-launch activities
(cid:131) During Optimization
Commercial traffic, subscribers using the network
Statistics used widely to monitor network performance
Drive testing just in case
All is about Post–launch activities
