I am developing an integrated network based on WLAN and UMTS technologies running VOIP. I am using OPNET. Can anyone discuss the follwing questions with me pls or show me examples of work done in OPNET:
1) How to intregrate these two networks (UMTS/WLAN) in OPNET? Shall I develop them seperately and then integrate them?
2) How to run and test VOIP and test quality of voice in OPNET over this integrated network?
