SON is crucial for the whole mobile industry (operators & vendors)

SON is real!! First features of SON expected soon:proof of concept done in field and lab testsavailability in live networks in 2010

improvements and further SON features to follow soon

We have to live the SON idea to make it happenWe are at the beginning of the road – keep on pushing
