What is DSA?

In-depth end-to-end RF and IP analysis toolcombination, enabling faster and pro-activeData Service performance analysis andtroubleshooting.

Close Integration of RF drive test and signallingtools makes it easier to get to the root cause ofproblems than with discrete tools.

To be on top of the wireless data, top-to-bottom visibility isrequired...

How well is the service performing?

What is the user experience?

What service have we committed to?

And what can we deliver?

Are any network devices down?

What components are performing poorly?

How heavily utilized are the links?

What caused the degradation in service?

What traffic is on the network?Any errors?

What’s causing traffic bottlenecks?

Handset problem? RF problem? Switching/routing problem? Signaling problem?Network congestion problem? Service configuration problem? ISP Problem?
