Network trendsSummary
We may use packets, but customers expect connections
The core remains smart but becomes homogonous and transport is separated from services and applications
Intelligence, differentiation, and interoperation characterize the network edge
No single access technology is likely to dominate in the near future
Seamless mobility is the umbrella application driving growth in telecommunication

In a packet environment, lower layer network performance is coupled to higher layer software configuration
Optimizing and troubleshooting next generation networks requires significant understanding of traditional data networking issues
If you are not looking at the network edge, you are missing much
Interoperability is less an issue between access technologies asit is between networks and between elements within your own network
CDMA decoding, usage monitoring, and interference analysis are the keys to RF-side optimization
