Joint processing between base stations has been shown as
an efficient technique to mitigate inter-cell interference and
increase data rates, in particular at the cell edges.
In this paper, we evaluate the utility of Internet applications
in a joint processing enabled cluster of base stations.
Utility is used to quantify system performance as
experienced by the end user.
In particular, the utility of three joint processing
schemes for the downlink is characterized and compared
within the cluster area.
The qualitative results indicate that joint processing
can significantly improve the utility of hard real-time
and adaptive applications.
For elastic applications, joint processing is not
worthwhile, since almost as high utility is achieved
also with conventional single base station assignment.
