2011년까지는 Voice가 Data보다많은 Traffic을 전송할 것임
1. Dominance of voice is still all-
encompassing for now
2. 2011 will be the watershed year
that data overtakes voice traffic as
networks undergo transformation
3. Operators must learn to cope with
the repercussions of the move to
a data-dominated world as traffic
and revenues become uncoupled
