Problems / Challenges


Repeat Dispatches

Slide 5

Repeat dispatches costs service providers millions -- about 15% of their repair business



Problems Coming Inside the Home

Leading Problems Reported by Customers:

Slow or intermittent Internet service

“Faulty” modem but 80% of time modem replacement is unnecessary

Random dropping of connection

Why are They Difficult to Diagnose:

Can’t determine where the problem exists

Can’t measure compliance to field test procedures

Inconsistent testing methods, tools and technical expertise

Slide 6

These problems are difficult to identify and repair. Unresolved, our field data shows they can lead to 10 – 15% of customer churn
